  • The Most Dangerous Thing in the Whole Universe


    Are you afraid of alien invasions or giant meteors rushing toward Earth? Oh, forget about them! There’s something much more dangerous lurking in space, and it’s called strange matter. While people don't know much about it, experts are sure that under particular conditions, this stuff would be able to eat our planet alive!

    Imagine a jar of honey that suddenly goes nuts and decides to consume everything around: the table, plates, your kitchen, you, the whole galaxy! That's exactly what may happen if the strange matter was left to roam on its own. But would there be a way to stop all this from happening?

    - Imagine this: a super powerful and massive star is reaching the end of its life. If the star had been massive enough, it’ll produce a black hole. But if it wasn't that big, a neutron star will appear in its place.
    - Scientists say that one day these neutrons can get tired of holding all that weight, and the structure keeping the entire thing together will collapse. This leads to the appearance of a quark star.
    - The pressure inside a quark star is getting stronger. As a result, things called “strange quarks” can appear in its core. They’ve been dubbed “strange” because, well, they don’t behave like normal quarks.
    - But strange matter – oh, that's a bundle of chaos! Here’s where the “strange” part comes in. Its quarks have no boundaries – they just run totally amok wherever and however they want.
    - When two neutron stars collide or when a neutron star crashes into a black hole, these strangelets break free. Sadly, a strangelet wouldn't care whether the object it's encountered is a star or a planet full of life!
    - To get rid of strange matter, the only thing we could do is toss it into a black hole. But this escape plan raises all kinds of questions itself.
    - But as soon as you get to the black hole’s edge, aka the event horizon, you won't be able to turn back because it’s the point of no return.
    - Everything that approaches a black hole gets broken down into individual atoms. And we become long thin pasta.
    - At this point, strange matter is just a theory that hasn't been confirmed yet. Physicists have considered creating strange matter in a particle accelerator. Luckily, they later came to the conclusion that it's impossible to do since particle accelerators get so hot that they’d immediately melt any appearing strangelets.

  • The Most Extreme Temperatures in the Universe


    Try to remember the hottest you've ever felt! The stifling heat and irking sensation of sweat trickling down your back and forehead. But if you think that was hot, what if I tell you there are things in our Universe that are literally billions of times hotter?

    As you may know, the Solar System itself can be a pretty scorching place. The average temperature of the Earth's core reaches a blazing 10,800 degrees F, which is 800 degrees higher than the surface of the Sun! As for the Sun's super-hot center, it heats up to 27,000,000 degrees F! But in terms of the Universe, these temperatures are nowhere near the hottest!

    Animation is created by Bright Side.

    - The temperature at the core of a supernova is an incredible 6,000 times higher than that of the Sun's core. And that means it can reach several billion degrees F within microseconds!
    - The highest temperature has been discovered - or is it better to say created? - on Earth; in Switzerland, to be exact.
    - In 2012, scientists at CERN's Large Hadron Collider crashed the ions of lead to cook a so-called subatomic soup. The result was a plasma with an astonishing temperature of 9.9 trillion degrees F!
    - Theoretically, there’s a point at which atoms stop moving. This temperature is called Absolute Zero, and it's equal to 0 degrees Kelvin or -459.67 degrees F.
    - Several places in the Solar System come pretty close to Absolute Zero. For example, craters near the South Pole of the Moon are permanently shadowed and never see sunlight.
    - But the most naturally-cold thing in the visible Universe is the mysterious Boomerang Nebula. This nebula is located approximately 5,000 light-years away from the Earth, and its temperature is considered to be just 1 Kelvin, or -four hundred some degrees F!
    - The coldest temperature people have ever recorded was on Earth! It happened in an Italian underground laboratory, where scientists chilled a 35-cubic-ft chunk of copper to an incredible 6 millikelvins.
    - The coldest habitable place in the world is Oymyakon village in Russia. There, the temperature often drops below 32 degrees F in September, and it doesn't get any warmer until the middle of April.
    - The temperature in the village dropped to -96 degrees F, which became the coldest recorded temperature in the Northern Hemisphere!
    - How about we move to the hottest place on the Earth? It's Death Valley in California. Unfortunately, researchers are still arguing about whether this place holds the record for the hottest ever recorded surface temperature: 201 degrees F on July 15, 1972.

  • Living Universe Journey To Another Stars Documentary 4K


    LIVING UNIVERSE is an interstellar adventure that seeks to answer the most profound question of all: are we alone? Based on the latest scientific knowledge, we will take a journey to a planet beyond our solar system in search of life. We ask the world's leading space scientists what we might find if we travel to a neighboring star system. Recent breakthroughs have proven that every star we see in the sky is orbited by at least one planet, many similar to our own Earth. How do we get to these exoplanets? Once there, what will we find? And what will it mean for humanity when we discover we are not alone? Our speculative journey through space is set a hundred years in the future - when we have the technology to journey well beyond our solar system. On this first expedition, our star ship Aurora will be piloted not by astronauts, but by the artificial intelligence (A.I.) we call Artemis. We imagine how Artemis travels through space, on its 25-year journey, at one fifth of the speed of light. Its objective is Minerva B, a planet much like our own, with an atmosphere, temperature and liquid water that appears a likely candidate to contain life. With spectacular special effects we will reach and explore a new planet as we seek to answer the most profound question of all: are we alone in the universe? Our guides on this journey are narrator Dr Karl Kruszelnicki and as the voice of our AI, Artemis, real-life astrophysicist, Professor Tamara Davis. Inspired and informed by our rapidly developing knowledge of far-off worlds, our best scientists - including NASA engineers, astrophysicists and astronomers - we will discover that this amazing journey is not only possible, it is inevitable. To venture into distant space is our destiny. LIVING UNIVERSE captures a pivotal moment in the human story. A film full of insight and inspiration certain to thrill anyone who dreams of distant worlds, or have ever wondered why are we here? Have you ever wondered that someone like you, sitting less than a mile away, in some other universe, exists? The possibility in itself seems frightening as well as astonishing. From breaking news and intriguing historical documentaries to conspiracy theories, classified NASA files and UFO's. We provide you with material that the government doesn't want you to see. The Insomnia team comes up with a promise. To keep up with the same, the team now brings to us a documentary that aims to change your perspective Of another existence, of another possibility, as today, the scientists now believe there may really be the presence of a parallel universe - and in fact, also believe that there may be an infinite number of parallel universes, and where we live today just happens to be only one of them and many of these other parallel universes come with different laws of physics as well. These other universes that we are talking about not only contain space, time and strange forms of exotic matter but to surprise you, Some of them may even contain you, only maybe in a slightly different form. The thought itself is quite intriguing and scary on the same hand. The basis of this theory is as we know it the idea that parallel universes are constantly spinning off from reality that we humans know of. Though generally ignored at the time, that theory has gone on to become not just a popular topic of study among respected physicists, but the inspiration for such popular films, television shows, and books as Star Trek and The Golden Compass. according to the sources. The video soon progresses into the Wilkinson Microwave Anisotropy Probe (WMAP), that is now changing everything, as some say that the remarkable images reveal the true shape of the universe through baby pictures of the same from the time when it was 4 hundred thousand years old, looking so back in time, when there wasn't even the formation of galaxies yet. The WMAP is catching the very first signs of creation as it is officially tagged with measuring radiation that is left over from Big Bang. And now scientists have devised an experiment to find the overall true shape of the universe. The WMAP hence shows that the universe is flat. From here arises the possibility of more mind boggling parallel universe that are of the level-2 type and is made up of giant cosmic soap bubbles that float in hyperspace. Each of these bubbles within it has a whole universe. Now, the question that arises is that - Do we all live in a giant cosmic bubble? Journey to another stars finding lives on other planets

  • A Journey to the End of the Universe


    What will happen to us in the next few hundred years? Or a thousand? How will the Universe end? Nobody knows for sure, but we can gather all the existing theories together and find it out. Just a century from now humans will be the first living species outside Earth that we know of. In 1,000 years, humanity will accept technology not only in their lives but inside their bodies too. Ever heard about cyborgs? That’s exactly what every other human being will become in the future.

    100,000 years in the future — and many of the constellations we know will become unrecognizable because of the natural movement of stars. At nearly the same time, Earth will celebrate the distant anniversary by a supervolcanic eruption, with hot magma and volcanic ash covering thousands upon thousands of square miles of land...

    - In 100 years, technology will leap forwards, and we’ll all become part of a web larger than the Internet. We’ll also finally start colonizing nearby planets, most likely Mars.
    - And here goes… 10,000 years from today. Antares, the red supergiant star that is fifteenth brightest in our night sky, will explode in a supernova.
    - 100,000 years in the future — and many of the constellations we know will become unrecognizable because of the natural movement of stars.
    - In 500,000 years, our planet will be struck with a huge boulder from the sky: an asteroid of about a half mile in diameter. If humans don’t find a way to avoid the impact, it will cause mass destructions on Earth.
    - In 1 million years, two out of four moons of Uranus will collide with each other, causing chaos on the planet.
    - Just 400,000 years later, Phobos, one of Mars’s two satellites, will break apart because of increasing gravity, and the red planet will have its own set of rings, just like Saturn.
    - 110 million years from now is when the Sun will become 1% brighter. It will change the climate on every planet in the Solar system, ever so slightly making it hotter and hotter still.
    - 4 billion years from now the Milky Way galaxy will collide with the Andromeda galaxy.
    - In 7.9 billion years, the Sun will become super-inflated and turn into a red giant, swallowing the closest planets — including the scalding hot piece of rock that was once Earth.
    - In 100 billion years, the Universe will stretch so far and so fast that galaxies will become invisible from each other’s perspective.
    - In 1 trillion years, new stars will stop appearing in space.
    - In 100 trillion years, the Degenerate Era will begin. With no fuel to feed the new stars, they will simply stop forming at all, even if some tried at first.
    - In 120 trillion years, only white and brown dwarf stars will remain where normal stars have once been.
    - In 1 quadrillion years, all planets will be thrown out of their orbits and sent drifting in the cold, dark outer space.
    - 1 quintillion years, and things that once were stars will also become ejected from their galaxies, wandering the empty Universe for the rest of their time.
    - Now, for quintillions of quintillions of years, there will be nothing; this period is called the Dark Era, and time won’t matter at this point.
    - The false vacuum has just inflated and heated up to extreme temperatures, exploding in the empty space and filling it with new energy.
    - Giving life to the new universe — and possibly not even a single one. You know this event as the Big Bang. That’s how our Universe was born, and how it will probably be reborn after billions upon billions of years.

  • A Journey to the End of the Universe


    Could humans ever travel to other galaxies within their lifetime? The immense scale of the Universe seems to prohibit such voyages, after all the nearest galaxy is so far away that it takes light itself - the fastest thing in the Universe - 2.5 million years to complete the trip. Remarkably, there is a trick that might allow humans to accomplish this feat - join us today as we step onboard the constantly accelerating spaceship!

  • 7 Most Surprising Things About the Universe


    Once upon a time, there was nothing. And in the blink of an eye... There was everything! And maybe, it wasn’t the first time! We know it as the Big Bang, the creation of our Universe billions of years ago. But what was before the Big Bang? And what if you put it all in reverse, and everything shrank back into a single point? Could this be the way the Universe ends?...

    The Big Bang happened around 13.8 billion years ago. The Universe was condensed in a single dot with the most extreme density and heat. Then it exploded into a colossal overheated ball of plasma. Turn your TV on an empty channel with the cable switched off – those black and white dots you see dancing around your screen are an imprint of Cosmic Microwave Background. Isn't it exciting? Here are some of the most surprising and interesting things about the Universe we live in.

  • 25 Strange Things About The Universe


    The universe we live in is a pretty remarkable place. And yet, we've only scratched its surface. From black holes thousands of times the mass of our Sun to galaxies crashing together in violent collisions, we live in an active and exciting universe. In this list, we've dug up plenty of the lesser-known facts and phenomena in the universe (strange things about the universe if you will). What unites them all is that they are generally unexpected or surprising. And most you've probably never even heard of. For instance, did you know it can take 100,000 Earth years for light to move from the core of the Sun to its surface? Or how about that it would take 74,000 Earth years to reach our next closest star? Or how about the possibility of an extraterrestrial radio transmission in 2012?

    Whether you're a space junkie or just a science fiction fan, there's plenty on this list of strange things about the universe to capture your interest. From the temperature of the Sun to the origin of comets to the music soundtrack humanity sent out to the stars in case other lifeforms find our space probes, put on your spacesuit and blast into these 25 Strange Things About the Universe.

    What is a neutron star? What are neutron stars made of? Well, they might not be as popular as black holes, but it doesn't make them any less enigmatic! Little is known about these super-dense remains of ancient stars. But one recent event may shed light on at least some of their mysteries!

    When energy starts to leave the fading star, it transforms into a neutron star. Energy is leaving it in the form of neutrinos - particles. During a supernova explosion, the star emits almost 10 times more neutrinos than the number of protons, electrons, and neutrons in the Sun! No wonder such conditions give birth to something truly scary…

  • ब्रह्मांड के १० अदभूत ग्रह | Top 10 Strange Planets in Universe in Hindi


    The term planet is ancient, with ties to history, astrology, science, mythology, and religion. Several planets in the Solar System can be seen with the naked eye. These were regarded by many early cultures as divine, or as emissaries of deities. As scientific knowledge advanced, human perception of the planets changed, incorporating a number of disparate objects. In 2006, the International Astronomical Union (IAU) officially adopted a resolution defining planets within the Solar System. This definition is controversial because it excludes many objects of planetary mass based on where or what they orbit. Although eight of the planetary bodies discovered before 1950 remain planets under the modern definition, some celestial bodies, such as Ceres, Pallas, Juno and Vesta (each an object in the solar asteroid belt), and Pluto (the first trans-Neptunian object discovered), that were once considered planets by the scientific community, are no longer viewed as such.

    We will see top 10 strange planets in universe in this episode.

    The Big Bang has been the accepted theory about the beginning of the universe for so long, you might think we've worked out all the kinks in it. But there are several issues with the Big Bang Theory, which has caused some cosmologists to turn to alternative ideas.

    The Ekpyrotic Universe, based on string theory, is one of those ideas. And it's super weird.

  • How Far You Could Go in the Universe


    Our world map was finally complete in the 1820s, with the discovery of Antarctica. But why stop at the end of the earth? Or the moon? What’s the farthest we could go?
    Despite all our advancements, for a very long time, the farthest man could travel was restricted to distances on the earth. In April of 1961, that all changed when humanity became a spacefaring species. The Russian cosmonaut, Yuri Gagarin, was the first man in space. He blasted into orbit on a 108-minute flight high above Earth. The Americans followed a few months later.

    - In 1969, the Apollo 11 mission landed the first two men on the Moon.
    - Another great feat was achieved the next year in April 1970, when the crew of NASA's Apollo 13 swung wide around the far side of the moon at an altitude of 158 miles, putting them 248,655 miles away from Earth.
    - Humans kept exploring in the hope that maybe there’s something beyond the Milky Way as well. At this point, astronomers noticed that some stars were dimmer than others.
    - Leavitt had studied thousands of Variable stars; stars whose brightness, as seen from the Earth, fluctuates. She found that if certain stars, known as Cepheid variables, pulsate at the same rate, they have the same brightness.
    - Around this time, work was also going on to install the Hooker telescope at Mount Wilson Observatory, California. This would be the world's largest telescope from 1917 to 1949.
    - The farthest galaxy observed is named EGS-zs8-1. The light from it took 13.1 billion years to reach us.
    - No one really knows what lies farthest from us, or how big our universe really is. Some say that the universe is edgeless, while others believe in a multiverse hypothesis.

  • Is the Universe Infinite?


    For more 4K space, and more great History and Science than you'll ever watch, check out our sister network...

    Explore the biggest question of all. How far do the stars stretch out into space? And what's beyond them? In modern times, we built giant telescopes that have allowed us to cast our gaze deep into the universe. Astronomers have been able to look back to near the time of its birth. They've reconstructed the course of cosmic history in astonishing detail.

    From intensive computer modeling, and myriad close observations, they've uncovered important clues to its ongoing evolution. Many now conclude that what we can see, the stars and galaxies that stretch out to the limits of our vision, represent only a small fraction of all there is.

    Does the universe go on forever? Where do we fit within it? And how would the great thinkers have wrapped their brains around the far-out ideas on today's cutting edge?

    For those who find infinity hard to grasp, even troubling, you're not alone. It's a concept that has long tormented even the best minds.

    Over two thousand years ago, the Greek mathematician Pythagoras and his followers saw numerical relationships as the key to understanding the world around them.

    But in their investigation of geometric shapes, they discovered that some important ratios could not be expressed in simple numbers.

    Take the circumference of a circle to its diameter, called Pi.

    Computer scientists recently calculated Pi to 5 trillion digits, confirming what the Greeks learned: there are no repeating patterns and no ending in sight.

    The discovery of the so-called irrational numbers like Pi was so disturbing, legend has it, that one member of the Pythagorian cult, Hippassus, was drowned at sea for divulging their existence.

    A century later, the philosopher Zeno brought infinity into the open with a series of paradoxes: situations that are true, but strongly counter-intuitive.

    In this modern update of one of Zeno's paradoxes, say you have arrived at an intersection. But you are only allowed to cross the street in increments of half the distance to the other side. So to cross this finite distance, you must take an infinite number of steps.

    In math today, it's a given that you can subdivide any length an infinite number of times, or find an infinity of points along a line.

    What made the idea of infinity so troubling to the Greeks is that it clashed with their goal of using numbers to explain the workings of the real world.

    To the philosopher Aristotle, a century after Zeno, infinity evoked the formless chaos from which the world was thought to have emerged: a primordial state with no natural laws or limits, devoid of all form and content.

    But if the universe is finite, what would happen if a warrior traveled to the edge and tossed a spear? Where would it go?

    It would not fly off on an infinite journey, Aristotle said. Rather, it would join the motion of the stars in a crystalline sphere that encircled the Earth. To preserve the idea of a limited universe, Aristotle would craft an historic distinction.

    On the one hand, Aristotle pointed to the irrational numbers such as Pi. Each new calculation results in an additional digit, but the final, final number in the string can never be specified. So Aristotle called it potentially infinite.

    Then there's the actually infinite, like the total number of points or subdivisions along a line. It's literally uncountable. Aristotle reserved the status of actually infinite for the so-called prime mover that created the world and is beyond our capacity to understand. This became the basis for what's called the Cosmological, or First Cause, argument for the existence of God.

    Here at SpaceRip, we value the exploration of the unknown. We surpass boundaries for the sake of uncovering the mysteries of the cosmos and what they may tell us about our origin and our future. With our videos, we hope to educate our viewers on how we fit into the universe, and more so how we can do our part to better it.

    We have partnered with MagellanTV with the goal of providing our viewers with insight regarding our uncertain future on Earth and beyond. Equipped with knowledge, we hope to inspire people to enact change and pave the way for a better tomorrow.

  • 5 Spacecraft Are Leaving The Solar System. What Did They See In Their Journey?


    Five spacecraft are leaving the solar system for good. Though we do not have the technology to land the first human on Mars, we have already accomplished the task of sending our robots into interstellar space.

    Pioneer 10: Pioneer 10 was launched in 1972 to explore the planets of the solar system. It achieved the first flyby of Mars, the first trip through the asteroid belt, and Jupiter's first flyby. It was the first time NASA had used nuclear energy to power its spacecraft. So, after Pioneer 10 passed Jupiter in 1973, it still had ample energy to keep going. Initially planned for 21 months, it continued to communicate with Earth for a total of 30 years.

    Pioneer 11: The twin spacecraft of Pioneer 10 saw similar success. It orbited Jupiter in 1974. Pioneer 11 became the first mission to ever encounter Saturn in 1979. It revealed what the ringed planet is made of and also discovered new moons of Saturn. Both these crafts are equipped with unique plaques designed to introduce their creators. NASA no longer receives signals from the Pioneer spacecraft.

    Voyager 1: Voyager 1 is the farthest spacecraft from Earth and is still in contact with NASA. It was launched in 1977 during a rare planetary alignment that takes place every 175 years. Jupiter, Saturn, Uranus, and Neptune were perfectly placed. NASA took advantage of this alignment. Voyager 1 made its flyby of Jupiter in 1979 and passed by Saturn in 1980. But instead of continuing to Uranus and Neptune, the craft changed its route to explore Titan. It's the largest moon of Saturn, having a thick atmosphere and methane lakes. In 2012, Voyager 1 reached the heliopause, a region where Sun's solar wind loses its sway. It became the first spacecraft to enter interstellar space. It is still sending data back to Earth. Voyager 1 is so far that radio signals take about 21 hours to get there. Voyager 1's course could bring it close to another star in some 40,000 years.

    Voyager 2: Voyager 2 was launched 15 days before its twin Voyager 1 in 1977. After exploring Jupiter and Saturn, Voyager 2 went on its planned trajectory. It became the first and the only probe to visit Uranus and Neptune to date. It entered interstellar space in 2018 and is still in contact with NASA.
    Just like Pioneer, both spacecraft contain identical copies of golden records.

    New Horizons: The most recent in the list, New Horizons was launched to explore Pluto. At Pluto, it found signs of ice volcanoes, giant mountains, and even a liquid water ocean. Now, New Horizons is continuing in the footsteps of the Pioneer and Voyager missions.

  • The Most Massive Objects In The Universe!


    Did you know that our universe is so big that we cannot really approximate its actual size?
    Now that you can imagine how our universe is extremely big, it’s easy to grasp that it’s filled with wonder-souly massive objects. Curious to know these objects in order? Keep watching!
    The Most Massive Objects in the Universe.

    Subscribe for more videos:
    Business Enquiries:
    Prior to stating the list of the most massive objects in the universe, it’s crucial to understand the concept of mass along with the astronomical mass units. Mass by definition is the measure of the amount of matter in an object usually measured in grams (g) or kilograms (kg), however due to the difficulties in measuring and expressing astronomical data in the international system of units (SI units); the Astronomical System of Units was developed in 1979 in which there was a redefinition of units of mass, time and length and the astronomical constants as well.
    The astronomical unit of mass is the solar mass aka the mass of the sun which is approximately equal to 1.98892 * 10^(30) kg and it’s the standard unit of describing the mass of stars and galaxies.

    Passage 1
    When it comes to cosmology, the term object is a loose concept because the universe is filled up with so many objects such as planets, stars, black holes and pulsars. However, one must ask “is any structure of gravitationally bound matter considered to be an object?” If the answer is yes, then we must consider nebulae, galaxies, galaxy clusters and the clusters of the galaxy clusters as objects as well. Moreover, we should consider the cosmic web, which is an overarching structure that holds all the matter in the universe as an object. Therefore, in this video we are introducing the most massive objects in the universe covering most of their types in descending order:

    10- As you probably know, the most massive object in the universe from the beginning of time is the universe itself right before the moment of the big bang. The big bang model states that the universe at the beginning 13.7 billion years ago was in an extremely hot and dense state, just try to imagine the total mass of the universe condensed into extremely infinitesimally small point-like singularity.

    9- Dark Energy; which constitutes 68% of the universe- you may wonder how on earth would energy be massive?! But thanks to Einstein’s energy-mass famous equation E=mc^(2) where c is the speed of light, transforming energy into mass is trivial. You may also have heard of the dark energy previously but let me explain its importance in detail… scientists in the early 1990s were fairly certain about some dynamics of the universe’s expansion; such that it might have enough energy density to stop its expansion and recollapse or it might have so little energy that it would never stop expanding, however, the gravitational forces were certain to slow the expansion as time went on due to the fact that our universe is full of matter and the attractive force of gravity pulls all matter together. However, in 1998, the Hubble Space Telescope (HST) observations of very distant supernovae showed that a long time ago; the universe was actually expanding more slowly than it is today. In other words, the expansion of the universe has not been slowing down due to gravity, as everyone expected, but it has been accelerating and something was causing this acceleration. Eventually, theorists still do not know what the correct explanation is but they have given the solution a name, it’s called the dark energy.
    More is unknown than is known about dark energy, the amount of dark energy is known because we know how it influences the universe’s expansion. There Are three possible explanations of dark energy, One explanation is that it’s a property of space -yes space has many amazing properties, many of which are just beginning to be understood- Einstein was the first to realize that empty space can possess its own energy, furthermore, it’s possible for more space to come into existence. And because this energy is a property of space itself, it would not be diluted as the space expands. Additionally, as more space comes into existence, more of this space-energy will appear which will be the reason that the universe will expand faster and faster. Unfortunately, there are some issues regarding this fancy model and related to the cosmological constant.
    8- Dark matter which constitutes 27% of the universe.

  • A Star 200 MLN Years Older Than the Universe Cant Be Explained


    Once upon a time, there was nothing. And, in an instant, there was everything! A Big Bang, and the universe was born! Then came the stars, the planets, collecting into galaxies and systems. But imagine there’s something that calls everything we know into question, nullifies the works of our greatest astronomers! Like, a star older than the universe?

  • Sound Of The Universe



    It's long been said that there's no sound in space, and that's true.
    Space is a vacuum, so it generally doesn’t carry sound waves like air does here on Earth. Though some sounds do exist in outer space, we just can’t hear them.

    These sound can’t be heard because there aren’t enough particles in space for sound waves to travel. So we can't hear anything with our natural ears.

    Turn your ears into radio wave receivers, and suddenly you can hear interesting sounds in space.

    There are various probes zooming through our cosmos, that are capable of capturing radio emissions from space objects. These radio emissions are then converted into sound waves.

    Here are some of the most interesting sounds of the universe.
