    “There are more stars in our Universe than there are grains of sand on all the beaches on Earth.” There are 100 to 400 billion stars in the Milky Way and more than 100 billion galaxies in the Universe – maybe as many as 500 billion. If you multiply stars by galaxies, at the low end, you get 10 billion billion stars, or 10 sextillion stars in the Universe – a 1 followed by 22 zeros. At the high end, it’s 200 sextillion.

    These are mind bogglingly huge numbers. How do they compare to the number of grains of sand on the collective beaches of an entire planet? This type of sand measures about a half millimeter across.

    You could put 20 grains of sand packed in side-by-side to make a centimeter. 8000 grains in one cubic centimeter. If you took 10 sextillion grains of sand, put them into a ball, it would have a radius of 10.6 kilometers. And for the high end of our estimate, 200 sextillion, it would be 72 kilometers across. If we had a sphere bigger than the Earth, it would be an easy answer, but no such luck. This might be close.

    So, is there that much sand on all the beaches, everywhere, on this planet? You’d need to estimate the average volume of a sandy beach and the average amount of the world’s coastlines which are beaches.

    The estimates and calculations made by Dr. Jason Marshall, aka, the Math Dude are that, there about 700 trillion cubic meters of beach of Earth, and that works out to around 5 sextillion grains of sand.

  • Star Size Comparison 2


    Dear world,
    Let´s talk about time.
    When I uploaded my first YouTube video 7 years ago, I would have never thought that it would get that much attention. Had lots of discussions, met new people, continued to make videos about things that intrigued me. Or tried out effects.

    I enjoyed it a lot, and I still read every comment that pops up. And they keep coming in. It is a hobby that I am very glad about having started. And I am humbled by the attention.

    Well, as time went by I found less time to work on videos, struggled with other things in life, and wondered if I would ever find the time again.

    But I always knew one thing:
    I owe you something. All the time people were are asking about a sequel to starsize comparison. And yes, I promised once.
    I keep my promises. So, whenever I found time over the last year I spent it on that. Here it is.
    I hope you like it. I tried to do it in a bit different way. Curious for the feedback. I know I will be hardly able to beat the choice of music from the first part, but let me say, Vangelis Alpha is a piece that is very dear to my heart, I always had this in mind.
    Still looking for contact to musicians.
    I do not know what the future brings, but I hope we will hear from each other. Enjoy.

  • How Large is the Universe?


    The universe has long captivated us with its immense scales of distance and time. How far does it stretch? Where does it end, and what lies beyond its star fields and streams of galaxies extending as far as telescopes can see?

    These questions are beginning to yield to a series of extraordinary new lines of investigation and technologies that are letting us to peer into the most distant realms of the cosmos. But also at the behavior of matter and energy on the smallest of scales. Remarkably, our growing understanding of this kingdom of the ultra-tiny, inside the nuclei of atoms, permits us to glimpse the largest vistas of space and time. In ancient times, most observers saw the stars as a sphere surrounding the earth, often the home of deities. The Greeks were the first to see celestial events as phenomena, subject to human investigation rather than the fickle whims of the Gods.

    One sky-watcher, for example, suggested that meteors are made of materials found on Earth... and might have even come from the Earth. Those early astronomers built the foundations of modern science. But they would be shocked to see the discoveries made by their counterparts today. The stars and planets that once harbored the gods are now seen as infinitesimal parts of a vast scaffolding of matter and energy extending far out into space.

    Just how far began to emerge in the 1920s. Working at the huge new 100-inch Hooker Telescope on California's Mt. Wilson, astronomer Edwin Hubble, along with his assistant named Milt Humason, analyzed the light of fuzzy patches of sky... known then as nebulae.

    They showed that these were actually distant galaxies far beyond our own. Hubble and Humason discovered that most of them are moving away from us. The farther out they looked, the faster they were receding. This fact, now known as Hubble's law, suggests that there must have been a time when the matter in all these galaxies was together in one place.

    That time, when our universe sprung forth, has come to be called the Big Bang. How large the cosmos has gotten since then depends on how long its been growing and its expansion rate. Recent precision measurements gathered by the Hubble space telescope and other instruments have brought a consensus...

    That the universe dates back 13.7 billion years. Its radius, then, is the distance a beam of light would have traveled in that time ... 13.7 billion light years. That works out to about 1.3 quadrillion kilometers. In fact, it's even bigger.... Much bigger. How it got so large, so fast, was until recently a deep mystery.

    That the universe could expand had been predicted back in 1917 by Albert Einstein, except that Einstein himself didn't believe it until he saw Hubble and Humason's evidence. Einstein's general theory of relativity suggested that galaxies could be moving apart because space itself is expanding.

    So when a photon gets blasted out from a distant star, it moves through a cosmic landscape that is getting larger and larger, increasing the distance it must travel to reach us. In 1995, the orbiting telescope named for Edwin Hubble began to take the measure of the universe... by looking for the most distant galaxies it could see.

    Taking the expansion of the universe into account, the space telescope found galaxies that are now almost 46 billion light years away from us in each direction... and almost 92 billion light years from each other. And that would be the whole universe... according to a straightforward model of the big bang. But remarkably, that might be a mere speck within the universe as a whole, according to a dramatic new theory that describes the origins of the cosmos.

  • Why Mars Died, and Earth Lived


    This video explores the most basic question of all: why we explore space? Be sure to experience the visual spectacle in full HD, 1080P.

    The Mars rover, Curiosity, is the latest in a long line of missions to Mars: landers sent to scoop its soil and study its rocks, orbiters sent to map its valleys and ridges.

    They are all asking the same question. Did liquid water once flow on this dry and dusty world? Did it support life in any form? And are there remnants left to find? The science that comes out of these missions may help answer a much larger, more philosophical question.

    Is our planet Earth the norm, in a galaxy run through with life-bearing planets? Or is Earth a rare gem, with a unique make-up and history that allowed it to give rise to living things? On Mars, Curiosity has spotted pebbles and other rocks commonly associated with flowing water.

    It found them down stream on what appears to be an ancient river fan, where water flowed down into Gale Crater. This shows that at some point in the past, Mars had an atmosphere, cloudy skies, and liquid water flowing. So what could have turned it into the desolate world we know today?

    One process that very likely played a role goes by the unscientific name, sputtering. Like the other planets in our solar system, Mars is lashed by high-energy photons from the Sun. When one of these photons enters the atmosphere of a planet, it can crash into a molecule, knocking loose an electron and turning it into an ion. The solar wind brings something else: a giant magnetic field. When part of the field grazes the planet, it can attract ions and launch them out into space.

    Another part might fling ions right into the atmosphere at up to a thousand kilometers per second. The ions crash into other molecules, sending them in all directions like balls in a game of pool. Over billions of years, this process could have literally stripped Mars of its atmosphere, especially in the early life of the solar system when the solar wind was more intense than it is today.

    Sputtering has actually been spotted directly on another dead planet, Venus. The Venus Express mission found that solar winds are steadily stripping off lighter molecules of hydrogen and oxygen. They escape the planet on the night side... then ride solar breezes on out into space.

    This process has left Venus with an atmosphere dominated by carbon dioxide gas... a heat trapping compound that has helped send surface temperatures up to around 400 degrees Celsius. The loss of Venus' atmosphere likely took place over millions of years, especially during solar outbursts known as coronal mass ejections.

    If these massive blast waves stripped Venus and Mars of an atmosphere capable of supporting life how did Earth avoid the same grim fate? We can see the answer as the solar storm approaches earth. Our planet has what Mars and Venus lack - a powerful magnetic field generated deep within its core.

    This protective shield deflects many of the high-energy particles launched by the Sun. In fact, that's just our first line of defense. Much of the solar energy that gets through is reflected back to space by clouds, ice, and snow.

    The energy that earth absorbs is just enough to power a remarkable planetary engine: the climate. It's set in motion by the uneveness of solar heating, due in part to the cycles of day and night, and the seasons. That causes warm, tropical winds to blow toward the poles, and cold polar air toward the equator.

    Wind currents drive surface ocean currents. This computer simulation shows the Gulf Stream winding its way along the coast of North America. This great ocean river carries enough heat energy to power the industrial world a hundred times over.

    It breaks down in massive whirlpools that spread warm tropical waters over northern seas. Below the surface, they mix with cold deep currents that swirl around undersea ledges and mountains. Earth's climate engine has countless moving parts: tides and terrain, cross winds and currents -- all working to equalize temperatures around the globe.

    Over time, earth developed a carbon cycle and an effective means of regulating green house gases. In our galaxy, are still-born worlds like Mars the norm? Or in Earth, has Nature crafted a prototype for its greatest experiment... Life?

    Big Bang Theory - The Premise
    The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment.

    According to the standard theory, our universe sprang into existence as singularity around 13.7 billion years ago. What is a singularity and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of black holes. Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called singularities. Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know.

    After its initial appearance, it apparently inflated (the Big Bang), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe. It continues to expand and cool to this day and we are inside of it: incredible creatures living on a unique planet, circling a beautiful star clustered together with several hundred billion other stars in a galaxy soaring through the cosmos, all of which is inside of an expanding universe that began as an infinitesimal singularity which appeared out of nowhere for reasons unknown. This is the Big Bang theory.

    Big Bang Theory - Common Misconceptions
    There are many misconceptions surrounding the Big Bang theory. For example, we tend to imagine a giant explosion. Experts however say that there was no explosion; there was (and continues to be) an expansion. Rather than imagining a balloon popping and releasing its contents, imagine a balloon expanding: an infinitesimally small balloon expanding to the size of our current universe.

    Another misconception is that we tend to image the singularity as a little fireball appearing somewhere in space. According to the many experts however, space didn't exist prior to the Big Bang. Back in the late '60s and early '70s, when men first walked upon the moon, three British astrophysicists, Steven Hawking, George Ellis, and Roger Penrose turned their attention to the Theory of Relativity and its implications regarding our notions of time. In 1968 and 1970, they published papers in which they extended Einstein's Theory of General Relativity to include measurements of time and space.1, 2 According to their calculations, time and space had a finite beginning that corresponded to the origin of matter and energy.3 The singularity didn't appear in space; rather, space began inside of the singularity. Prior to the singularity, nothing existed, not space, time, matter, or energy - nothing. So where and in what did the singularity appear if not in space? We don't know. We don't know where it came from, why it's here, or even where it is. All we really know is that we are inside of it and at one time it didn't exist and neither did we.
    Big Bang Theory - The Only Plausible Theory?
    Is the standard Big Bang theory the only model consistent with these evidences? No, it's just the most popular one. Internationally renown Astrophysicist George F. R. Ellis explains: People need to be aware that there is a range of models that could explain the observations….For instance, I can construct you a spherically symmetrical universe with Earth at its center, and you cannot disprove it based on observations….You can only exclude it on philosophical grounds. In my view there is absolutely nothing wrong in that. What I want to bring into the open is the fact that we are using philosophical criteria in choosing our models. A lot of cosmology tries to hide that.4

  • 13 MIND BLOWING Discoveries - 2017!


    Most amazing recent discoveries! Top unbelievable science facts that we recently learned in the last few years

    13. The Cave Angel Fish
    Ever since the publication of his book On the Origin of Species in 1859, scientists have been searching for evidence to fill the gaps in Charles Darwin’s theory of evolution. In 1985, researchers discovered Cryptotora thamicola, more commonly known as the waterfall climbing fish or the cave angel fish. Found predominantly in water-filled caves in Thailand, this reclusive fish can climb steep inclines both in and out of water. It belongs to the hillstream loach family, a durable grouping of marine life that grows in algae. While other sea creatures such as pricklebacks, killifishes, eels, mudskippers, frogfish and some species of catfish are capable of temporary land-dwelling or mobility on the ocean floor, the cave angel fish is the only one with the sophisticated spinal and fin structure to do both. Its discovery brought researchers one step closer to understanding how the first vertebrates emerged from the sea roughly 375 million years ago.

    12. Data Super Storage
    In 2013, data storage experts from the University of Southampton in England demonstrated the concept of five-dimensional data storage. By early 2016, their method reached its prototype phase with the creation of an encoded disc capable of storing unparalleled file sizes and amounts that could last for up to 14 billion years. Unlike other forms of data storage, the 5D disc uses a protected form of digital dimensions called nano-gratings. Unlike optical discs like the everyday CD, 5D technology allows information to be stored more densely and is less vulnerable to heat or chemical corruption. The first files preserved using this new technology were the United Nations’ Universal Declaration of Human Rights, the King James Bible, and the book Opticks by Isaac Newton. Though it will likely be a few decades before these super-discs are available for widespread commercial use, the scientists who created them are already looking into more economical ways to duplicate and distribute their game-changing technology.

    11. Understanding Malaria
    Researchers in the College of Medicine at Penn State University have discovered the process by which Plasmodium falciparum, the deadliest malaria parasite, attacks red blood cells by overtaking the immune system. Using proteins that are meant to protect the human body from outside infection, P. falciparum reverses the normal process of attacking invading bacteria by causing antibodies to do the opposite of what they are supposed to - turning against the body itself. When these defenses become immobilized, the parasite targets red blood cells and spreads the virus throughout the body. In discovering this previously-unknown tactic of the disease, researchers gained an invaluable and long-awaited insight into developing a stronger vaccine.

    10. The Known Placebo Effect
    The placebo effect describes the physical or mental state of relief experienced by an oblivious patient after they are provided with a treatment or prescription that does not contain any real medical component. Such “placebos” are often given out in the form of innocuous supplements like sugar pills. This phenomenon has been the subject of extensive debate and research within the scientific community since it was discovered by by a medic during World War II. But the recent emergence of the “known placebo effect” may entirely change the way doctors attend to their patients. Researchers at Harvard Medical School have introduced the concept of what they call “open-label placebos.” These are prescriptions that patients are honestly told do not contain any proven medical benefit before they take them. Despite being aware of their so-called medication’s complete lack of chemical integrity, many patients in an irritable bowel syndrome study experienced significant symptom relief. While it is unlikely to become a realistic treatment for all diseases, further examination of the known placebo effect has the potential to revolutionize medical care in the 21st Century.

  • The Largest Black Holes in the Universe


    Our Milky Way may harbor millions of black holes... the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there's evidence of something far more ominous. A breed of black holes that has reached incomprehensible size and destructive power. Just how large, and violent, and strange can they get?

    A new era in astronomy has revealed a universe long hidden to us. High-tech instruments sent into space have been tuned to sense high-energy forms of light -- x-rays and gamma rays -- that are invisible to our eyes and do not penetrate our atmosphere. On the ground, precision telescopes are equipped with technologies that allow them to cancel out the blurring effects of the atmosphere. They are peering into the far reaches of the universe, and into distant caldrons of light and energy. In some distant galaxies, astronomers are now finding evidence that space and time are being shattered by eruptions so vast they boggle the mind.

    We are just beginning to understand the impact these outbursts have had on the universe: On the shapes of galaxies, the spread of elements that make up stars and planets, and ultimately the very existence of Earth. The discovery of what causes these eruptions has led to a new understanding of cosmic history. Back in 1995, the Hubble space telescope was enlisted to begin filling in the details of that history. Astronomers selected tiny regions in the sky, between the stars. For days at a time, they focused Hubble's gaze on remote regions of the universe.

    These hubble Deep Field images offered incredibly clear views of the cosmos in its infancy. What drew astronomers' attention were the tiniest galaxies, covering only a few pixels on Hubble's detector. Most of them do not have the grand spiral or elliptical shapes of large galaxies we see close to us today.

    Instead, they are irregular, scrappy collections of stars. The Hubble Deep Field confirmed a long-standing idea that the universe must have evolved in a series of building blocks, with small galaxies gradually merging and assembling into larger ones.

  • Voyager Journey to the Stars


    Cosmic Journeys examines the great promise of the Voyager mission and where it will lead us in our grand ambition to move out beyond our home planet. The two Voyager spacecraft are part of an ancient quest to push beyond our boundaries... to see what lies beyond the horizon. Now tens of billions of kilometers from Earth, two spacecraft are streaking out into the void. What will we learn about the Galaxy, the Universe, and ourselves from Voyager's epic Journey to the stars?

    December 19, 1972... the splashdown of the Apollo 17 crew capsule marked the end of the golden age of manned spaceflight. The Mercury.... Gemini... and Apollo programs had proven that we could send people into space... To orbit the Earth.... Fly out beyond our planet... Then land on the moon and walk among its ancient crater.

    The collective will to send people beyond our planet faded in times of economic uncertainty, war, and shifting priorities. And yet, just five years after Apollo ended, scientists launched a new vision that was just as profound and even more far-reaching.

    It didn't all go smoothly. Early computer problems threatened to doom Voyager 2. Then its radio receiver failed, forcing engineers to use a back up. Now, after more than three and a half decades of successful operations, the twin spacecraft are sending back information on their flight into interstellar space. Along the way, they have revealed a solar system rich beyond our imagining.

    The journey was made possible by a rare alignment of the planets, a configuration that occurs only once every 176 years. That enabled the craft to go from planet to planet, accelerating as they entered the gravitational field of one, then flying out to the next. The Voyagers carried a battery of scientific equipment to collect data on the unknown worlds in their path. That included a pair of vidicom cameras, and a data transfer rate slower than a dialup modem.

  • The Most Powerful Objects in the Universe


    All across the immense reaches of time and space, energy is being exchanged, transferred, released, in a great cosmic pinball game we call our universe.

    How does energy stitch the cosmos together, and how do we fit within it? We now climb the power scales of the universe, from atoms, nearly frozen to stillness, to Earth's largest explosions. From stars, colliding, exploding, to distant realms so strange and violent they challenge our imaginations. Where will we find the most powerful objects in the universe?

    Today, energy is very much on our minds as we search for ways to power our civilization and serve the needs of our citizens. But what is energy? Where does it come from? And where do we stand within the great power streams that shape time and space?

    Energy comes from a Greek word for activity or working. In physics, it's simply the property or the state of anything in our universe that allows it to do work. Whether it's thermal, kinetic, electro-magnetic, chemical, or gravitational.

    The 19th century German scientist Hermann von Helmholtz found that all forms of energy are equivalent, that one form can be transformed into any other. The laws of physics say that in a closed system - such as our universe - energy is conserved. It may be converted, concentrated, or dissipated, but it's never lost.

    James Prescott Joule built an apparatus that demonstrated this principle. It had a weight that descended into water and caused a paddle to rotate. He showed that the gravitational energy lost by the weight is equivalent to heat gained by the water from friction with the paddle. That led to one of several basic energy yardsticks, called a joule. It's the amount needed to lift an apple weighing 100 grams one meter against the pull of Earth's gravity.

    In case you were wondering, it takes about one hundred joules to send a tweet, so tweeted a tech from Twitter. The metabolism of an average sized person, going about their day, generates about 100 joules a second, or 100 watts, the equivalent of a 100-watt light bulb.

    In vigorous exercise, the power output of the body goes up by a factor of ten, one order of magnitude, to around a thousand joules per second, or a thousand watts. In a series of leaps, by additional factors of ten, we can explore the full energy spectrum of the universe.

    Exploring Stars in Our Galaxy - Full Documentary


    Exploring The Southern Stars - Full Documentary
    Billions and billions of stars in a galaxy (after a quote often mistakenly attributed to Carl Sagan) is how many people imagine the number of stars you would find in one. Is there any way to know the answer for sure?

    It's a surprisingly difficult question to answer. You can't just sit around and count stars, generally, in a galaxy, said David Kornreich, an assistant professor at Ithaca College in New York State. He was the founder of the Ask An Astronomer service at Cornell University.

    Even in the Andromeda Galaxy — which is bright, large and relatively close by Earth, at 2.3 million light-years away — only the largest stars and a few variable stars (notably Cepheid variables) are bright enough to shine in telescopes from that distance. A sun-size star would be too difficult for us to see. So astronomers estimate, using some of the techniques below.

    Massive investigation
    The primary way astronomers estimate stars in a galaxy is by determining the galaxy's mass. The mass is estimated by looking at how the galaxy rotates, as well as its spectrum using spectroscopy.

    All galaxies are moving away from each other, and their light is shifted to the red end of the spectrum because this stretches out the light's wavelengths. This is called redshift. In a rotating galaxy, however, there will be a portion that is more blueshifted because that portion is slightly moving toward Earth. Astronomers must also know what the inclination or orientation of the galaxy is before making an estimate, which is sometimes simply an educated guess, Kornreich said.

    A technique called long-slit spectroscopy is best for performing this type of work. Here, an elongated object such as a galaxy is viewed through an elongated slit, and the light is refracted using a device such as a prism. This breaks out the colors of the stars into the colors of the rainbow.

    Some of those colors will be missing, displaying the same patterns of missing portions as certain elements of the periodic table. This lets astronomers figure out what elements are in the stars. Each type of star has a unique chemical fingerprint that would show up in telescopes. (This is the basis of the OBAFGKM sequence astronomers use to distinguish between types of stars.)

    Any kind of telescope can do this sort of spectroscopy work. Kornreich often uses the 200-inch telescope at the Palomar Observatory at the California Institute of Technology, but he added that almost any telescope of sufficient size would be adequate.

    The ideal would be using a telescope in orbit because scattering occurs in Earth's atmosphere from light pollution and also from natural events — even something as simple as a sunset. The Hubble Space Telescope is one observatory known for this sort of work, Kornreich added.
    The number of stars is approximately …
    So is there any way to figure out how many stars are for sure? In the end, it comes down to an estimate. In one calculation, the Milky Way has a mass of about 100 billion solar masses, so it is easiest to translate that to 100 billion stars. This accounts for the stars that would be bigger or smaller than our sun, and averages them out. Other mass estimates bring the number up to 400 billion.

    The caveat, Kornreich said, is that these numbers are approximations. More advanced models can make the approximation more accurate, but it would be very difficult to count the stars one by one and tell you for sure how many are in the galaxy.

  • Smartass Kids Who Maybe Will Go Far In Life


    Kids. Some are smarter than others. But sometimes the kids that are considered the least smart are actually the smartest of all. But these kids aren't thinking technically. They're thinking much deeper than that. They're seeing THROUGH the question in order to get to the very heart of what's being asked. And that takes brains. Which is why we think that all these kids deserve an A for Awesome. Or, at the very least, an E for Effort.

    Every other Wednesday we present a new video, so join us to see the truth laid bare...

    Just for a moment, imagine a universe awash with life, where we humans are not the only intelligent beings around. What might these alien races look like? Could we communicate with them, or even recognise them as intelligent? And what would they make of our violent and dangerous species? Might they take one look, and decide not to bother with such primitive beings? A planetary nursery filled with spiteful, galactic infants. On the other hand, in our imaginary scenario, they may enrich us with scientific knowledge beyond our imagination. Or could an encounter with aliens have a more destructive outcome? It could be a bad day for human kind. But relax, it’s just make believe, it could never happen, could it?

    A mysterious crash in Roswell, New Mexico during the 1940s convinced many that our planet is being visited by space aliens. Crop circles in Britain have only added fuel to the fire. Few scientists doubt that life indeed exists elsewhere, but some believe we're more likely to make contact via radio waves. Join the search for extra-terrestrials and hear from scientists who think we are on the verge of making contact.

    Quantum mechanics (QM -- also known as quantum physics, or quantum theory) is a branch of physics which deals with physical phenomena at nanoscopic scales where the action is on the order of the Planck constant. It departs from classical mechanics primarily at the quantum realm of atomic and subatomic length scales. Quantum mechanics provides a mathematical description of much of the dual particle-like and wave-like behavior and interactions of energy and matter. Quantum mechanics provides a substantially useful framework for many features of the modern periodic table of elements including the behavior of atoms during chemical bonding and has played a significant role in the development of many modern technologies.

    In advanced topics of quantum mechanics, some of these behaviors are macroscopic (see macroscopic quantum phenomena) and emerge at only extreme (i.e., very low or very high) energies or temperatures (such as in the use of superconducting magnets). For example, the angular momentum of an electron bound to an atom or molecule is quantized. In contrast, the angular momentum of an unbound electron is not quantized. In the context of quantum mechanics, the wave--particle duality of energy and matter and the uncertainty principle provide a unified view of the behavior of photons, electrons, and other atomic-scale objects.

    The mathematical formulations of quantum mechanics are abstract. A mathematical function, the wavefunction, provides information about the probability amplitude of position, momentum, and other physical properties of a particle. Mathematical manipulations of the wavefunction usually involve bra--ket notation which requires an understanding of complex numbers and linear functionals. The wavefunction formulation treats the particle as a quantum harmonic oscillator, and the mathematics is akin to that describing acoustic resonance. Many of the results of quantum mechanics are not easily visualized in terms of classical mechanics. For instance, in a quantum mechanical model the lowest energy state of a system, the ground state, is non-zero as opposed to a more traditional ground state with zero kinetic energy (all particles at rest). Instead of a traditional static, unchanging zero energy state, quantum mechanics allows for far more dynamic, chaotic possibilities, according to John Wheeler.

    The earliest versions of quantum mechanics were formulated in the first decade of the 20th century. About this time, the atomic theory and the corpuscular theory of light (as updated by Einstein)[1] first came to be widely accepted as scientific fact; these latter theories can be viewed as quantum theories of matter and electromagnetic radiation, respectively. Early quantum theory was significantly reformulated in the mid-1920s by Werner Heisenberg, Max Born and Pascual Jordan, (matrix mechanics); Louis de Broglie and Erwin Schrödinger (wave mechanics); and Wolfgang Pauli and Satyendra Nath Bose (statistics of subatomic particles). Moreover, the Copenhagen interpretation of Niels Bohr became widely accepted. By 1930, quantum mechanics had been further unified and formalized by the work of David Hilbert, Paul Dirac and John von Neumann[2] with a greater emphasis placed on measurement in quantum mechanics, the statistical nature of our knowledge of reality, and philosophical speculation about the role of the observer. Quantum mechanics has since permeated throughout many aspects of 20th-century physics and other disciplines including quantum chemistry, quantum electronics, quantum optics, and quantum information science. Much 19th-century physics has been re-evaluated as the classical limit of quantum mechanics and its more advanced developments in terms of quantum field theory, string theory, and speculative quantum gravity theories.

  • Universe: Beyond the Millennium - Alien Life


    Universe: Beyond the Millennium is a television series observing astronomical phenomena, research, and theories on the universe and its origins.

    Narrated by John Hurt.

    The documentary premiered in 1999 and presents an overview of the universe as humans understood it at that time, and how we think it will evolve in the next millennium. Using 3D computer generated graphics, the series features animated sequences that offer insight into the Big Bang theory and the anatomy of the sun.

    Alien Life, when NASA scientists found a lump of rock from Mars with microscopic fossils in it, the search for extraterrestrial life beyond our own became a credible objective. Researchers and scientists from SETI (Search for Extra-Terrestrial Intelligence) have spent decades trying to determine how an alien life force would contact us and if one does, how we would reply.

    At the start of a new millennium we're about to embark on the greatest adventure of all time. Five hundred million miles from Earth, a spacecraft will land on Jupiter's icy moon, Europa. It's mission, to search for alien life. As we reach out across the galaxy, our spacecraft will explore the most extreme environments to answer the ultimate question, are we alone?

  • Massive Object the size of Mars may lurk beyond Neptune - Planet 10?


    An unknown, unseen planetary mass object may lurk in the outer reaches of our solar system, according to new research on the orbits of minor planets to be published in the Astronomical Journal. This object would be different from—and much closer than—the so-called Planet Nine, a planet whose existence yet awaits confirmation.

    In the paper, Kat Volk and Renu Malhotra of the University of Arizona's Lunar and Planetary Laboratory, or LPL, present compelling evidence of a yet-to-be- discovered planetary body with a mass somewhere between that of Mars and Earth. The mysterious mass, the authors show, has given away its presence—for now—only by controlling the orbital planes of a population of space rocks known as Kuiper Belt objects, or KBOs, in the icy outskirts of the solar system.

  • The Big Bang Theory : The Universe, The Space-time, And The Relativity Amazing Production


    The Universe is all of spacetime and everything that exists therein, including all planets, stars, galaxies, the contents of intergalactic space, the smallest subatomic particles, and all matter and energy.[1][2][3][4][5][6] Similar terms include the cosmos, the world, reality, and nature.

    The estimated diameter of the observable universe is about 93 billion light years or 28 billion parsecs.[7] Scientific observation of the Universe has led to inferences of its earlier stages, which appear to have been governed by the same physical laws and constants throughout most of its extent and history. The Big Bang theory is the prevailing cosmological model that describes the early development of the Universe, which is estimated to have begun 13.798 ± 0.037 billion years ago.[8][9]

    Scientists remain unsure about what, if anything, preceded the Big Bang. Many refuse to speculate, doubting that any information from any such prior state could ever be accessible.[citation needed] There are various multiverse hypotheses, in which some physicists have suggested that the Universe might be one among many, or even an infinite number, of universes that likewise exist.[10][11]

    The universe is composed of 4.9 percent atomic matter, 26.6 percent dark matter and 68.5 percent dark energy[12] Observations of supernovae have shown that the Universe is expanding at an accelerating rate.[13] There are several competing theories about the ultimate fate of the universe.

    If Alien exist where do they live and how do they live?
    Scientists say a world that's 490 light-years away qualifies as the first confirmed Earth-sized exoplanet that could sustain life as we know it — but in an environment like nothing we've ever seen.
    The planet, known as Kepler-186f, is more of an Earth cousin than an Earth twin, Elisa Quintana, an astronomer at the SETI Institute at NASA Ames Research Center, told the journal Science. Quintana is the lead author of a report on the planet published by Science this week.
    This discovery does confirm that Earth-sized planets do exist in the habitable zones of other stars, Quintana said during a Thursday news briefing at NASA Headquarters.
    Kepler-186f goes around an M-type dwarf star that's smaller and cooler than our sun. But it orbits much closer to its parent star than Earth does, within what would be Mercury's orbit in our own solar system. Those two factors combine to produce an environment that could allow for liquid water on the surface, assuming that the planet had a heat-trapping atmosphere.

    The star, to our eyes, would look slightly orange-y, about a third again as big as our sun but only a third as bright, said co-author Thomas Barclay, a staff scientist for NASA's Kepler mission who is also affiliated with NASA and the Bay Area Environmental Research Institute. At midday, Kepler-186f's landscape might look similar to what we see on Earth an hour before sunset, he told NBC News.
    Or it might not: If the planet lacked an atmosphere to retain and redistribute its sun's warmth, it would be a cold, dry, lifeless world.

    Kepler-186f probably rates as the most potentially Earthlike planet discovered so far, said Jim Kasting, a geoscientist at Penn State University who did not play a role in the Science study. But he told NBC News that it's still less likely to be habitable than planets around more sunlike stars. Even better prospects for alien habitability might well be identified in the months and years to come.

    How the world was found

    Kepler-186f is just the latest discovery to be pulled out of terabytes' worth of data collected by the Kepler mission. Before it went on the fritz last year, the Kepler space telescope stared at more than 150,000 stars in a patch of sky, looking for the telltale dimming of starlight as planets passed over the stars' disks. Nearly 1,000 exoplanets have been confirmed using Kepler data, and almost 3,000 more candidates are still awaiting confirmation.

    It takes years of observation to confirm the pattern of dimming and brightening that's associated with alien planets, particularly if the planets are small and far from their parent stars. In February, astronomers reported that at least four worlds circled the dwarf star known as Kepler-186 or KOI-571. In this week's Science paper, Quintana and her colleagues confirm the existence of Kepler-186f as the fifth and outermost world.
    They report that Kepler-186f is about 10 percent wider than Earth, tracing a 130-day orbit around its sun at a mean distance of 0.35 astronomical units. (An astronomical unit is the distance between Earth and our sun, which is 93 million miles or 150 million kilometers.) That would put Kepler-186f on the cooler, outer side of the star's habitable zone — the range of orbital distances where liquid water could exist on a planet's surface.

    Astronomers have confirmed the existence of other planets in their stars' habitable zone, but those prospects are super-Earth-size. Smaller habitable-zone candidates also have been found, but they have yet to be confirmed as planets.

    Barclay said Kepler-186f was particularly promising because it's less than 1.5 times the size of Earth. Planets in that size range are more likely to be rocky with a thinner atmosphere, like Earth, Mars and Venus. But worlds exceeding that size stand a better chance of retaining a thick atmosphere of hydrogen and helium, like the giant planet Neptune.

    While those planets also could be rocky, they don't remind us of home, Barclay said.
    Could we actually detect signs of life on Kepler-186f? That's a tough one. The astronomers behind the discovery acknowledge that the planet might be just too far away for follow-up studies. The SETI Institute has been searching for radio signals from the Kepler-186 system over a wide frequency range (1 to 10 GHz), but so far nothing has been detected.

    The Universe in a Nutshell: The Physics of Everything
    Michio Kaku, Henry Semat Professor of Theoretical Physics at CUNY

    What if we could find one single equation that explains every force in the universe? Dr. Michio Kaku explores how physicists may shrink the science of the Big Bang into an equation as small as Einstein's e=mc^2. Thanks to advances in string theory, physics may allow us to escape the heat death of the universe, explore the multiverse, and unlock the secrets of existence. While firing up our imaginations about the future, Kaku also presents a succinct history of physics and makes a compelling case for why physics is the key to pretty much everything.

  • what is gravity in Hindi ? | Newtons gravity - Part - 1 | the mystery of gravity | Documentary |


    welcome in your physics tv India

    visit Blog to know more:-

    Gravity, or gravitation, is a natural phenomenon by which all things with mass are brought toward (or gravitate toward) one another, including planets, stars, and galaxies. Since energy and mass are equivalent, all forms of energy, including light, also cause gravitation and are under the influence of it. On Earth, gravity gives weight to physical objects and causes the ocean tides. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing, forming stars – and the stars to group together into galaxies – so gravity is responsible for many of the large-scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker on farther objects.

    Hour long complete version of The New History of Humanity by Deek Jackson

    Extract - Hunting 2 MA

    Until recently the oldest, unchallenged evidence of human hunting came from a 400,000-year-old site in Germany the evidence came from marks left by spears on horse bones - horses were clearly being speared and their flesh eaten. but new Evidence from ancient butchery site in Tanzania shows early man used complex hunting techniques to ambush and kill antelopes, gazelles, wildebeest and other large animals at least two million years ago.- The discovery -- by anthropologist Professor Henry Bunn of Wisconsin University -- pushes back the definitive date for the beginning of systematic human hunting by hundreds of thousands of years.
    Two million years ago, our human ancestors were small-brained apemen previously many scientists assumed the meat they butchered and ate had been gathered from animals that had died from natural causes or had been left behind by lions, leopards and other carnivores - We know that humans ate meat two million years ago, said Bunn, speaking at the European Society for the study of Human Evolution (ESHE). What was not clear was the source of that meat. However, we have compared the type of prey killed by lions and leopards today with the type of prey selected by humans in those days. This has shown that men and women could not have been taking kill from other animals or eating those that had died of natural causes. They were selecting and killing what they wanted.
    Once our species got a taste for meat, it was provided with a dense, protein-rich source of energy. We no longer needed to invest internal resources on huge digestive tracts that were previously required to process vegetation and fruit, which are more difficult to digest. This new, energy-rich resource was then diverted inside our bodies and used to fuel our growing brains. over the next two million years our crania grew, producing species of humans with increasingly large brains

  • The Search for Intelligent Life Among the Stars: New Strategies


    January 20, 2010
    Dr. Seth Shostak (SETI Institute)

    A half-century ago, astronomers began trying to eavesdrop for radio messages from nearby star systems. Today, SETI (Search for Extra-Terrestrial Intelligence) researchers continue to point their telescopes at individual stars, on the assumption that technically advanced societies will inhabit a watery world like our own. Seth Shostak describes these searches, but then discusses some novel ideas for how we might pursue the hunt for cosmic company and why it's possible that we might find evidence of sophisticated intelligence out there within only a few decades. Shostak is Senior Astronomer at the SETI Institute, in Mountain View, California and hosts the syndicated radio show called Are We Alone?
