    00:00 Spacesuit
    Before spaceflight aviators began wearing pressure suits to allow them to function at higher ceilings. These aviation suits were adapted for the early Cosmonauts and Astronauts but as requirements became more demanding spacesuit design became more elaborate.
    This episode looks at the evolution of the modern spacesuit, capable of supporting life in extreme conditions.

    25:44 The Other Planets
    For most of human history our neighbouring planets were little more that dots of light in the sky with comets and asteroids being a complete mystery. Today the smaller rocky planets and asteroids are seen as the key to understanding in the formation of our planetary system.
    This episode reveals what we know about the solar system’s difficult to reach planets and the probes that have visited them.

  • PLANET JUST LIKE EARTH: Alien Life - National Geographic Documentary HD

    50:42

    When NASA began 60 years ago, we had questions about the universe humans had been asking since we first looked up into the night sky. In the six decades since, NASA, along with its international partners and thousands of researchers, have expanded our knowledge of the Universe by using a full fleet of telescopes and satellites. From the early probes of the 1950s and 1960s to the great telescopes of the 1990s and 21st century, NASA scientists have been exploring the evolution of the universe from the Big Bang to the present.

    The Great Observatories
    NASA astronomers use several kinds of telescopes in space and on the ground. Each observes targets like stars, planets, and galaxies, but captures different wavelengths of light using various techniques to add to our understanding of these cosmic phenomenon.
    Dark Matter
    NASA telescopes have helped us better understand this mysterious, invisible matter that is five times the mass of regular matter. The first direct detection of dark matter was made in 2007 through observations of the Bullet Cluster of galaxies by the Chandra x-ray telescope.

    Black Holes
    Although we can’t “see” black holes, scientists have been able to study them by observing how they interact with the environment around them with telescopes like Swift, Chandra, and Hubble. In 2017, NASA's Swift telescope has mapped the death spiral of a star as it is consumed by a black hole. This year, astronomers using Chandra have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy.
    Galaxies
    A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, held together by gravity. Some are spiral-shaped like our Milky Way Galaxy; others are smooth and oval shaped. NASA telescopes are helping us learn about how galaxies formed and evolved over time.
    Exoplanets
    Just 30 years ago, scientists didn’t know if there were planets orbiting other stars besides our own Sun. Now, scientists believe every star likely has at least one exoplanet. They come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big as Earth or Mars. They can be hot enough to boil metal or locked in deep freeze. They can orbit their stars so tightly that a “year” lasts only a few days; they can even orbit two stars at once. Some exoplanets don’t orbit around a star, but wander through the galaxy in permanent darkness. NASA’s Kepler spacecraft and newly-launched Transiting Exoplanet Survey Satellite are helping us find more distant worlds

    3:37:19

    We Are Not Alone In The Universe
    I cannot imagine any single discovery that would have more impact on humanity than the discovery of life outside of our solar system. There is a human-centric, Earth-centric view of life that permeates most cultural and societal thinking. Finding that there are multiple, perhaps millions of origins of life and that life is ubiquitous throughout the universe will profoundly affect every human.

    We live on a microbial planet. There are one million microbial cells per cubic centimeter of water in our oceans, lakes, and rivers; deep within the Earth's crust and throughout our atmosphere. We have more than 100 trillion microbes on and in each of us. The Earth's diversity of life would have seemed like science fiction to our ancestors. We have microbes that can withstand millions of Rads of ionizing radiation; such strong acid or base that it would dissolve our skin; microbes that grow in ice and microbes that grow and thrive at temperatures exceeding 100 degrees C. We have a life that lives on carbon dioxide, on methane, on sulfur, or on sugar. We have sent trillions of bacteria into space over the last few billion years and we have exchanged material with Mars on a constant basis, so it would be very surprised if we do not find evidence of microbial life in our solar system, particularly on Mars.

    The recent discoveries by Dimitar Sasselov and colleagues of numerous Earth and super-Earth-like planets outside our solar system, including water worlds, greatly increases the probability of finding life. Sasselov estimates approximately 100,000 Earth and super-Earths within our own galaxy. The universe is young so wherever we find microbial life there will be intelligent life in the future.

    Expanding our scientific reach further into the skies will change us forever.

  • Is Alien ‘Life’ Weirder Than We Imagine: Who Is Out There?

    59:56

    If we want to discover alien life out there in the universe, we first need to figure out where to look—and what we're even looking for. Will it be biological like us? Could it be artificial, or take some other form we haven't yet considered? And how do we find something so fundamentally different from ourselves? In this program, scientists devise plans for searching for beings beyond Earth while they grapple with the very definition of life.

  • Space Science Documentary - Searching for ANOTHER Earth - The Planet Hunters Guide

    30:01

    The planets around our star, the sun, are not the only ones out there. For years, people have wondered what exists beyond the one star, eight planets, and 710,000 minor planets (including dwarf planets, asteroids, etc.) in our Solar System. In 600 BC, exoplanets were discussed as we would discuss the idea of alternative universes today – once Aristotle landed on the idea of Earth being unique, that was that and all speculation was shut down. It wasn’t until the Renaissance that the idea was revisited by Giordano Bruno. He claimed that there are ‘countless suns and countless Earths rotating around their suns in exactly the same way’, and that we only see their suns rather than the planets themselves. His teachings led him to be executed for blasphemy and heresy, and his idea was rejected.

    In the 20th century, ideas moved more rapidly. Isaac Newton also hypothesised that exoplanets exist, but had no means of testing his hypothesis. In 1952, Otto Struve claimed that we only know of our star and our Solar System but that there is more beyond. In 1992, Wolszczan and Frail found other stars at the end of their lives (pulsars), and three years later Mayor and Queloz observed a Jupiter-sized planet (now termed a “hot Jupiter”) that orbit around their stars. The idea that exoplanets exist had sunk in.

    Dark energy has a finite density, approximately 68% of the total energy density of the Universe. ... If the actual Universe is infinite, extending forever beyond our cosmological event horizon, then the total dark energy is infinite, but that beyond our cosmological event horizon can never interact with us.

  • The Best Documentary Ever!! - The Story Of Earth And Life

    1:30:01

    The best documentary to watch high and sober.

    The Earth might seem solid beneath our feet but five billion years ago there was no sign of the planet we call home. Instead there was only a new star and a cloud of dust in our solar system. Over millions of years, a series of violent changes led to the formation of our world and, eventually, the creation of life.

    In this photorealistic CGI epic, see how a boiling ball of rock transformed into the blue planet we know today. Explore every aspect of our world; learn how water first arrived on Earth, discover the vital role oxygen played as life forms began to evolve, and find out how land mammals evolved into dinosaurs and other giant beasts, before becoming extinct 65 million years ago.

    Cutting-edge imagery also reveals how humans first began to walk on two feet and looks into the future to see what may be in store for our home over the next five billion years.

  • Gaias mission: solving the celestial puzzle

    19:59

    A space mission to create the largest, most-accurate, map of the Milky Way in three dimensions will revolutionise our understanding of the galaxy and the universe beyond.

    On 19th December 2013, a rocket blasted into the sky from a launch site in French Guiana and travelled 1.5 million km to reach its destination in orbit around the Sun. The spacecraft is called Gaia. Its mission, funded by the European Space Agency and involving scientists from across Europe, is to make the largest, most precise, three-dimensional map of the Milky Way ever attempted.

    It will be a census of a billion stars spread across our galaxy. The results, says Professor Gerry Gilmore from Cambridge's Institute of Astronomy and the Principal Investigator for UK involvement in the mission, will revolutionise our understanding of the cosmos as never before.



  • UFOS & ALIENS - The Myth Of Space Travel | SPACETIME - SCIENCE SHOW

    48:51

    For more than 40 years, people have lived in space over longer periods of time - first on the space stations Saljut and Skylab, today on the international space station ISS, and perhaps soon in a spaceship on its way to Mars. But man is not made for space. The universe is so hostile to life that humans can not survive there permanently. Skeptics, conspiracy theorists claim that all manned space travel is just a well-staged drama and the moon landing is the biggest lie of all. Since man has set out to conquer outer space and then the universe, conspiracy theorists accompany the work of scientists and explorers. And at the same time, UFOs (unidentified flying objects) have been sighted with claims of visits by your favorite martian aka extraterrestrials. Mankind’s advance into space has triggered the imagination of earthlings since humans first looked up at the stars. And so, in addition to the epochal discoveries, countless myths and legends have arisen as well.

    The world is not enough for conspiracy theories. Since the first launches into space numerous myths and legends around space travel and astronauts abounded. The first images from space depicted our planet in spherical form. All lies was a cry heard immediately from so-called experts.: The earth is and remains a disc. To this day, there are advocates of the flat earth theory, which was actually refuted even before the birth of Christ.

    The claim that the earth is flat was almost extinct, but the Internet is helping fuel this theory in a kind of renaissance of fools. Any kind of conspiracy theory ever invented in the context of space travel is getting a revival in the age of the world wide web. The biggest of all is the denial of the successful landing of man on the moon.

    Hardly any other human event spawned such wild speculation as Neil Armstrong's moon landing as well as the eleven other US astronauts. Just a few months after the first steps on the Moon, skeptics accused NASA, its scientists and astronauts, and the entire US government as liars. The landing never took place, the live images were recorded in Hollywood studios, the whole moon program is a huge bluff. To this day, despite proof to the contrary, the conspiracy theorists continue to beat the drum of denial.
    But there is also a lot happening on planet Earth. Ever since man conquered space, first with balloons and then with airplanes, earth dwellers regularly sight unknown flying objects: UFOs. The first UFOs were reported at the end of the 19th century; at about the same time as the first attempts to launch aircraft heavier than air into the sky. The UFOs levitate alien creatures on Earth to collect humans as research objects or to keep in contact with the powerful leaders of the world. There’s more: US military are thought to have captured several extraterrestrials and keep them hidden in a secret facility, including the flying saucers they landed with. The site: A US Air Force test site in the Nevada desert known as Area 51.
    But even everyday problems and phenomena of manned and unmanned space travel repeatedly create fodder for skeptics, doubters and conspiracy theorists. Sci Fi movies are also fantastic sources for creating new myths and legends.
    In this Episode of Spacetime we try to shed some light on the dark realm of conspiracies, myths and legends. Astronaut Ulrich Walter explains what really happens to people in space, should they find themselves without a spacesuit. He shows us how to live and survive in weightlessness and why even flights deep into the solar system do not have to be lethal to humans. We look at what UFO sightings are all about and what's behind them and why Area 51 is so mysterious.
    We examine the surface of Mars, which appeared on the first photos of the Red Planet and terrified crowds of people. We explain the function of the warp drive and whether you can really travel through the universe with it. And of course we explain why man actually set foot on the moon.

  • What is Space Time and How it Works | Documentary

    42:22

    The time scale of the universe is very long compared to that for human life. It was therefore not surprising that until recently, the universe was thought to be essentially static, and unchanging in time. On the other hand, it must have been obvious, that society is evolving in culture and technology. This indicates that the present phase of human history can not have been going for more than a few thousand years. Otherwise, we would be more advanced than we are. It was therefore natural to believe that the human race, and maybe the whole universe, had a beginning in the fairly recent past. However, many people were unhappy with the idea that the universe had a beginning, because it seemed to imply the existence of a supernatural being who created the universe. They preferred to believe that the universe, and the human race, had existed forever. Their explanation for human progress was that there had been periodic floods, or other natural disasters, which repeatedly set back the human race to a primitive state.

    This argument about whether or not the universe had a beginning, persisted into the 19th and 20th centuries. It was conducted mainly on the basis of theology and philosophy, with little consideration of observational evidence. This may have been reasonable, given the notoriously unreliable character of cosmological observations, until fairly recently. The cosmologist, Sir Arthur Eddington, once said, 'Don't worry if your theory doesn't agree with the observations, because they are probably wrong.' But if your theory disagrees with the Second Law of Thermodynamics, it is in bad trouble. In fact, the theory that the universe has existed forever is in serious difficulty with the Second Law of Thermodynamics. The Second Law, states that disorder always increases with time. Like the argument about human progress, it indicates that there must have been a beginning. Otherwise, the universe would be in a state of complete disorder by now, and everything would be at the same temperature. In an infinite and everlasting universe, every line of sight would end on the surface of a star. This would mean that the night sky would have been as bright as the surface of the Sun. The only way of avoiding this problem would be if, for some reason, the stars did not shine before a certain time.

    In a universe that was essentially static, there would not have been any dynamical reason, why the stars should have suddenly turned on, at some time. Any such lighting up time would have to be imposed by an intervention from outside the universe. The situation was different, however, when it was realised that the universe is not static, but expanding. Galaxies are moving steadily apart from each other. This means that they were closer together in the past. One can plot the separation of two galaxies, as a function of time. If there were no acceleration due to gravity, the graph would be a straight line. It would go down to zero separation, about twenty billion years ago. One would expect gravity, to cause the galaxies to accelerate towards each other. This will mean that the graph of the separation of two galaxies will bend downwards, below the straight line. So the time of zero separation, would have been less than twenty billion years ago.

    At this time, the Big Bang, all the matter in the universe, would have been on top of itself. The density would have been infinite. It would have been what is called, a singularity. At a singularity, all the laws of physics would have broken down. This means that the state of the universe, after the Big Bang, will not depend on anything that may have happened before, because the deterministic laws that govern the universe will break down in the Big Bang. The universe will evolve from the Big Bang, completely independently of what it was like before. Even the amount of matter in the universe, can be different to what it was before the Big Bang, as the Law of Conservation of Matter, will break down at the Big Bang.

    Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory, and say that time began at the Big Bang. Events before the Big Bang, are simply not defined, because there's no way one could measure what happened at them. This kind of beginning to the universe, and of time itself, is very different to the beginnings that had been considered earlier. These had to be imposed on the universe by some external agency. There is no dynamical reason why the motion of bodies in the solar system can not be extrapolated back in time, far beyond four thousand and four BC, the date for the creation of the universe, according to the book of Genesis. Thus it would require the direct intervention of God, if the universe began at that date. By contrast, the Big Bang is a beginning that is required by the dynamical laws that govern the universe. It is therefore intrinsic to the universe, and is not imposed on it from outside.

  • Alien Contact: Outer Space | Full UFO Documentary

    1:3:15

    **This film is under license from Vision Films Inc. All rights reserved**

    Alien Contact: Outer Space - Many people think of Space as a quiet and desolate vacuum of emptiness, but new evidence reveals that space is rife with activity beyond our comprehension. Just as we sent Voyager and Pioneer probes beyond our solar system, Aliens have probes of their own that may have arrived as early as the 1600's. While Tesla was the first to successfully communicate with neighboring worlds using radio waves, we have received recent signals from intelligent sources. In 1989, Russian Space Probe Phobos 2 photographed a UFO on the surface of Mars just prior to losing contact. Scientists have determined that the craft was real and of a thin elliptical shape over 20 miles in length. We are not alone in outer space and while the Aliens may be initiating contact, they could also be here already.
