How the Edge of Our Galaxy Defies Known Physics

  • How the Edge of Our Galaxy Defies Known Physics


    How is it possible that you can't see 95% of the universe? The edge of our milky way defies known physics, so physicists are using the LHC at CERN to search for Dark Matter.

    Dianna Cowern from Physics Girl visited CERN and spoke to theoretical physicists about Dark Matter.

    Why this stuff costs $2700 Trillion per gram: (Antimatter at CERN)

    Lots of people believe the Universe is infinite, but there's a good possibility that might not be the case. Which means that there would be an actual edge of the Universe. What happens at that edge? Is there a restaurant? Join Matt on this week’s episode of Space Time as he explores the greatest expanses of our Universe. So what do you find when you reach the edge? More Universe? Bubble Universes? Back where you started?! Check out this episode of Space Time to find out!

  • The Edge of an Infinite Universe


    Have you ever asked “what is beyond the edge of the universe?” And have you ever been told that an infinite universe that has no edge? You were told wrong. In a sense. We can define a boundary to an infinite universe, at least mathematically. And it turns out that boundary may be as real or even more real than the universe it contains.

    Our universe may be infinite. In order to wrap our puny human minds around such a notion we like to come up with boundaries. For example we have the “observable universe” – that patch that we can see, and beyond which light has not yet had time to reach us. It’s boundary is called the particle horizon. Beyond it there exists at a minimum of thousands and possibly infinitely more regions just as large. Our observable universe is like a tiny patch of land in a vast plain. We define its horizon like we might build a little picket fence around our little patch – meaningless from the point of view of the plain, but it makes our patch feel more homey and us less crushingly insignificant.

  • 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!

    Special thanks to Prof. Mason Porter at UCLA who I interviewed for this video.

    I have long wanted to make a video about chaos, ever since reading James Gleick's fantastic book, Chaos. I hope this video gives an idea of phase space - a picture of dynamical systems in which each point completely represents the state of the system. For a pendulum, phase space is only 2-dimensional and you can get orbits (in the case of an undamped pendulum) or an inward spiral (in the case of a pendulum with friction). For the Lorenz equations we need three dimensions to show the phase space. The attractor you find for these equations is said to be strange and chaotic because there is no loop, only infinite curves that never intersect. This explains why the motion is so unpredictable - two different initial conditions that are very close together can end up arbitrarily far apart.

  • Beyond the Cosmic Horizon


    In 2012, scientists detected the most distant galaxy discovered to date. This galaxy is now expected to be over 46 billion light years from the Earth, at the very edge of the observable universe. But what differentiates the observable universe and the rest of the universe? Today, we examine how a 13 billion year-old universe can be hundreds of billions of light years in diameter, and what might be waiting for us behind the barrier of the cosmic horizon.

    Today we're going to focus on education and learn more about space and space facts that you probably didn't know about! As has been famously said, space is the final frontier. The greatest of unknowns, space is far vaster than we can comprehend, and filled with phenomenon we barely understand. While we've been watching the heavens in awe for millennia, space exploration and discovery only began in earnest in the mid 20th century. Yet even what are no doubt our primitive findings still point at a universe more incredible than we ever thought. Hello and welcome to another episode of The Infographics Show - today we're taking a look at 50 incredible facts about space!

  • Why This Stuff Costs $2700 Trillion Per Gram - Antimatter at CERN


    Physics Girl is on Patreon! ►►

    There’s a factory in Europe that makes antimatter! It’s the rarest, most expensive, and potentially the most dangerous material on earth. Scientists don’t know why this material is so rare. Anti-atoms took 72 years after we discovered antimatter to make. Why?

    Thanks to CERN, Elise Wursten, Loïc Bommersbach and Sarah Charley

    Creator/Host: Dianna Cowern
    Editor: Levi Butner
    Research & Writing: Sophia Chen & Dianna & Imogen Ashford

    Current estimate of Antimatter, courtesy of Elise:
    Stefan Ulmer made a back-of-the-envelope calculation based on energy and power consumption. The explanation goes as follows:
    1. CERN produces 3e7 antiprotons per AD cycle or about 1e15 per year
    2. This is about 1e15*1.67e-27kg = 1.67 nanogram per year
    3. 1 gram of antiprotons has an energy (E=mc^2) of 9e13 Joule
    4. The efficiency of the antiproton production process is 1e-9, so you need a billion times more energy: 9e22 Joule
    5. The cost of power for CERN is 1kWh = 3.6e6 Joule = 0.1 euro
    6. So that would make 0.1/3.6e6*9e22 = 2.5e15 euro
    7. And it would take CERN 6e8 years

  • The Extreme Physics Pushing Moore’s Law to the Next Level


    A look inside a new precision machine that wants to reinvent the chip making industry.
    »Subscribe to Seeker!
    »Watch more Focal Point |

    An integrated circuit, or chip, is one of the biggest innovations of the 20th century. The microchip launched a technological revolution, created Silicon Valley, and everyone’s got one in their pocket (read: smartphones).

    When you zoom in on one of these chips, you find a highly complex, nanoscale-sized city that’s expertly designed to send information back and forth.

    And chip manufacturers continue to shrink the size of microchips, hitting smaller and smaller milestones while also increasing the number of features a chip has. The result is an improved overall processing power.

    This is what’s been driving the semiconductor industry—a drumbeat called Moore’s Law.

    Moore's Law is the golden rule in computing: The number of transistors on a microchip can be expected to double every two years, while the cost of computers is cut in half. This basically means we'll have more speed, at less cost, over time. And so, we've been shrinking transistors (the tiny electric switches that process data for everything from clocks to AI algorithms) down to really, really tiny nanoscales.

    And though we've hit a physical limit on how small these transistors can get, Intel (and a couple other competitors, like Samsung and TSMC) are betting big on something new: EUV Lithography.

    Find out more about this next generation of chip technology that is taking Moore’s Law to a new level on this episode of Focal Point.

    EUV Lithography Finally Ready for Chip Manufacturing

    “The giant machine garnering all this attention is an extreme ultraviolet lithography tool. For more than a decade, the semiconductor-manufacturing industry has been alternately hoping EUV can save Moore’s Law and despairing that the technology will never arrive. But it’s finally here, and none too soon.”

    Moore's Law Keeps Going, Defying Expectations

    “It’s a mystery why Gordon Moore’s “law,” which forecasts processor power will double every two years, still holds true a half century later”

    Silicon Valley Owes Its Success To This Tech Genius You’ve Never Heard Of

    “They called Robert Noyce the Mayor of Silicon Valley, but like many in public office, his work wasn’t well known.”

  • Whats Inside A Black Hole? | Unveiled


    What's Inside A Black Hole?

    Black holes are mysterious and bizarre objects in the universe that really have no explanation. In fact, we hardly know anything about what lies inside of a black hole. We know and understand what we see on the outside of a black hole, but we have no way of going inside one to take a look at what is really happening. Even if we sent a probe inside a black hole, it would not survive the journey, and there would be no way that the probe could transmit a signal outside once it had been sucked inside. This is because a black hole is the product of mass being squeezed together so densely, and so tightly, that it creates a gravitational pull that is so strong, that not even light can escape its grasp.

    Supermassive black holes with masses millions to billions of times that of the sun are thought to lurk at the hearts of all galaxies in the universe. You may notice that when you see a photo of a spiral galaxy, such as the Milky Way, in the center of the galaxy is a giant mass of light, which many people would think looks like a massive sun.

    But this is not light coming from the black hole itself. Remember, that light cannot escape the heavy gravitational pull. Instead, the light we see comes from the magnetic fields near a spinning black hole that propel electrons outward in a jet along the rotation axis. The electrons produce bright radio waves. Quasars are believed to produce their energy from massive black holes in the center of the galaxies in which the quasars are located. Because quasars are so bright, they drown out the light from all the other stars in the same galaxy.

    You’re probably asking, ‘well, what’s a quasar?’ A Quasar is the short name for ‘quasi-stellar object’ and is a very highly energetic object surrounding an actively feeding Supermassive Black Hole. In more basic terms, the Supermassive Black Hole in the middle of a galaxy feeds intermittently. As it feeds, gas swirls around it at incredible speeds and forms an insanely bright hot orbiting disk. And if the black hole is swallowing a large amount of material, this feeding is accompanied by gigantic jets of gas. These are called Quasar. They are essentially fueled by the Black Holes they orbit.

  • The Truth About Gravity With Professor Jim Al-Khalili | Gravity And Me | Spark


    Physics professor Jim Al-Khalili investigates the amazing science of gravity. A fundamental force of nature, gravity shapes our entire universe, sculpting galaxies and warping space and time. But gravity's strange powers, discovered by Albert Einstein, also affect
    our daily lives in the most unexpected ways. As Jim tells the story of gravity, it challenges his own understanding of the nature of reality.
    The science of gravity includes the greatest advances in physics, and Jim recreates groundbreaking experiments in gravity including
    when the Italian genius Galileo first worked out how to measure it.

    Gravity science is still full of surprises and Jim investigates the latest breakthrough - 'gravity waves' - ripples in the vast emptiness of space. He also finds out from astronauts what it's like to live without gravity.

    But gravity also directly affects all of us very personally - making a difference to our weight, height, posture and even the rate at which we age. With the help of volunteers and scientists, Jim sets out to find where in Britain gravity is weakest and so where we weigh the least. He also helps design a smartphone app that volunteers use to demonstrate how gravity affects time and makes us age at slightly different rates.

    And finally, Jim discovers that despite incredible progress, gravity has many secrets.

  • The Secrets Of Quantum Physics with Jim Al-Khalili | Spark


    Professor Jim Al-Khalili traces the story of arguably the most important, accurate and yet perplexing scientific theory ever: quantum physics.

    The story of quantum physics starts at the beginning of the 20th century with scientists trying to better understand how light bulbs work. This simple question soon led scientists deep into the hidden workings of matter, into the sub-atomic building blocks of the world around us. Here they discovered phenomena unlike any encountered before - a realm where things can be in many places at once, where chance and probability call the shots and where reality appears to only truly exist when we observe it.

    Albert Einstein hated the idea that nature, at its most fundamental level, is governed by chance. Jim reveals how in the 1930's, Einstein thought he'd found a fatal flaw in quantum physics. This was not taken seriously until it was tested in the 1960s. Professor Al-Khalili repeats this critical experiment, posing the question does reality really exist, or do we conjure it into existence by the act of observation?

    Elsewhere, we explore how the most famous law of quantum physics – The Uncertainty Principle – is obeyed by plants and trees as they capture sunlight during the vital process of photosynthesis. Could quantum mechanics explain the greatest mystery in biology - evolution?

  • bluedot 2018 | Jim Al-Khalili: Entanglement and Wormholes


    Quantum mechanics is one of the most powerful and successful theories in all of science, but what it tells about the fundamental building blocks of matter can be very baffling. Physicists and chemists have had to get used to this strangeness, but biologists have so far got away without having to worry too much about it. However, times are changing. There is now solid evidence that many fundamental processes inside living cells rely on the weird rules of the quantum world, from enzymes to photosynthesis to the way our sense of smell works. There is even the hint that some birds navigate during migration thanks to quantum entanglement. This talk introduced the exciting new field of Quantum Biology by one of its foremost practitioners.

    bluedot is an award-winning weekend of discovery at the grounds of the Jodrell Bank deep space observatory. Set against a backdrop of the iconic Lovell Telescope, bluedot combines a truly stellar line-up of music with a ground-breaking programme of live science experiments, expert talks and immersive artworks.

  • Mysteries of Modern Physics by Sean Carroll


    One of the great intellectual achievements of the twentieth century was the theory of quantum mechanics, according to which observational results can only be predicted probabilistically rather than with certainty. Yet, after decades in which the theory has been successfully used on an everyday basis, most physicists would agree that we still don’t truly understand what it means. I will talk about the source of this puzzlement, and explain why an increasing number of physicists are led to an apparently astonishing conclusion: that the world we experience is constantly branching into different versions, representing the different possible outcome of quantum measurements. This could have important consequences for quantum gravity and the emergence of spacetime.

    Sean Carroll is a theoretical physicist at the California Institute of Technology, and an External Professor at the Santa Fe Institute. He is the host of the weekly Mindscape podcast. He is the author of several books, most recently Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime.

    Black Holes and the Structure of Spacetime by Juan Maldacena

    DATE: 25 May 2018, 16:00 to 18:00
    VENUE: Chandrasekhar Auditorium, ICTS, Bangalore

    Black holes are fascinating objects predicted by Einstein's theory of general relativity. Though they were initially viewed as pathological and unphysical solutions, they were later understood to be a solid and generic outcome of the theory. They are objects where the distortion of space and time is so extreme that it defies imagination. Black holes give rise to paradoxes whose resolution requires us to modify our conception of spacetime. We will review how black holes went from being an apparently unphysical solutions to a central tool for discovering new perspectives on the nature of spacetime.

  • 10 Real Things That Defy The Laws Of Physics


    10 Real Things That Defy The Laws Of Physics

    The human race has come a long way all thanks to our knowledge of science. We now have a far much better understanding of why and how things happen in a certain way.
    But that is not to say we have it all figured out. Some laws of Physics become obsolete when we consider a couple of stuff around us. And that’s the focus of our video today – 10 things that don’t care what Physics says.
    #10 Particles That Travel Faster Than Light
    Light travels at a speed of 299,792,458 meters per second. Commonly, this is the highest known speed that any particle can travel at. And that’s for a good reason.
    One of the 20th century’s brightest minds Albert Einstein had drawn this conclusion. According to his special relativity theory, the speed of light is the maximum pace for both energy and matter.
    The law has been used extensively in the world of Physics and is a core component in Einstein’s theory. And it’s no surprise. Albert was an intelligent chap and wielded a certain kind of influence in the scientific community – he still does, by the way.
    But in 2011, something interesting happened. A group of physicists behind the Oscillation Project with Emulsion-tracking Apparatus (OPERA) experiment discovered that some particles can travel faster than light.
    In the experiment, the scientists beamed neutrinos from CERN lab near Geneva, Switzerland to the Gran Sasso National Laboratory in Italy. The distance between the two is approximately 730 kilometers.
    The result?
    The beam of neutrinos reached its destination about 60 nanoseconds early meaning it traveled at a speed faster than that of light, hence, quashing Einstein's special theory of relativity. Of course, there was a lot of skepticism in the science community when this revelation was released but more tests proved wrong a law that had been around for over a century.
    #9 Tetraneutron
    A tetraneutron is hypothetical for a larger part with papers from as far back as 1965 disputing its existence. Tetraneutron here refers to a lone cluster of four neutrons, existing without any protons. This is impossible when you take into account the instability of neutrons.
    There have always been attempts to observe them, though. One of these was in 2001 led by theoretical physicist Francisco-Miguel Marques at Ganil accelerator in Caen, France.
    The researchers fired atomic nuclei at a carbon target – this is a standard practice in most particle accelerator experiments. In this experiment, the scientists used beryllium-14, beryllium-15, and lithium-11.
    By doing this, they were trying to separate beryllium’s cluster of four neutrons. They observed a single flash of light and hypothesized that it could have been caused by four neutrons hitting the same place at the same time. But since their results couldn’t be replicated, this observation was written off.
    Another close-enough experiment was conducted in 2016 in Japan. In this case, a beam of helium-8 was fired at helium-4, occasionally producing beryllium-8 nuclei. The tetraneutron might have appeared briefly in this experiment.
    #8 The Quantum Zeno Effect
    Wikipedia defines the quantum Zeno effect as the suppression of unitary time evolution in quantum systems provided by measurement, interactions with the environment, stochastic fields and so on.
    In simpler terms, the quantum Zeno effect refers to a situation where a system is adamant to change because of being under constant observation.
    It sounds crazy since the behavior of a particle isn’t usually determined with whether the said particle is being watched or not. A decaying sample, for instance, will go on doing so regardless of whether you have your eyes peeled on it or not. This is so since there is no connection between being watched and decaying.
    Take uranium for instance. It’s a highly unstable substance and will undergo radioactive decay over time. But when scientists in Texas sat down to watch a sample, nothing happened. But when they left, the decay went on as usual.
    #7 Starlite
    Starlite first became known to the public in 1990 thanks to BBC which featured it on the program “Tomorrow’s World”. It was a kind of a heat barrier that was quite revolutionary at that time.

  • Looking Into the Center of the Galaxy


    Astrophysicist Rachel Smith is an observer of forming stars. From 20,000 light years away, Smith trawls the frontiers of our galaxy searching through the chemistry of where in the universe Earth-like planets could exist.

    “You have a puzzle with a million or a billion pieces, and we’ve got one piece,” explains Smith. “I’m interested in the chemistry of what’s going on from where we are to where the center of our galaxy is.”

    In episode five of The Most Unknown, Smith travels to Hawaii’s W.M. Keck Observatory with astrobiologist Luke McKay to explore the Milky Way using Keck’s powerful twin telescopes perched atop the Big Island’s dormant Mauna Kea volcano.
