  • THE UNIVERSE - Out of Nothing: Infinity | SPACETIME - SCIENCE SHOW

    48:20

    SPACETIME - SCIENCE SHOW: The beginning of everything was the Big Bang. The creation of our universe was set in motion. But what came before the big bang? And what happened right after the big bang? We are fascinated by the infinite vastness of the universe. A vastness inconceivable to anything we can imagine. But how do we know that the universe is infinite? These are the questions humanity has been preoccupied with since we looked up at the stars: where do we come from? Where are we going? And where is our place in the infinity of the cosmos?

    The Big Bang is the absolute starting point of our universe. The birth of space and time. But was there really nothing before that? A nothing beyond our imagination, or was there something before the big bang? What cosmologists and astrophysicists can say with certainty: Our universe came into existence exactly 13.8 billion years ago. And everything started from a single speck. A tiny speck where our three-dimensional universe, space, was buried. But where was this speck, this dot? There is no answer comprehensible for average human imagination. Only mathematics helps here. And it states: this three-dimensional, strongly curved speck was just there.

    After the big bang, our universe ballooned. And continues to expand today, maybe for all eternity. Nevertheless, astronomers define the universe as manageable: it is as big as the eye can see. It consists of what we can observe in principle. In order to discover and observe galaxies and stars, we need to light. The light of our central star, our sun, takes 8 minutes to reach us. The light of the nearest stars a few years. Tens of thousands of years from the next galaxies. The Hubble Space Telescope photographs galaxies several billion light-years away, and satellites measure the microwave radiation produced only 400,000 years after the Big Bang. With this data, cosmologists measure our universe in space and time.

    Let there be light! In this episode of Spacetime, Professor Ulrich Walter explains how out of nowhere our universe emerged. How it expanded, and what happened and continues to happen today. We focus on the question whether our Universe will last forever, or whether it is finite. What would happen at the end? We examine the phenomena that our cosmos holds: What are dark energy and dark matter? Why black holes exist and how do wormholes work? Are there really parallel universes? And what does the detection of gravitational waves mean for science? We look at the theories, methods and instruments that cosmologists use to track down the origin and function of our universe.
    The view into space gives us images of a fascinating and bewildering beauty. Landscapes of light and gas and stardust, shaped by cosmic wind and radiation. We are surrounded by an intangible infinity. A universe in which the earth is just a grain of sand on the beach of an ocean. But we are deciphering more and more secrets of the universe around us.

  • The Edge of an Infinite Universe

    18:30

    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.

  • Frank Wilczek, The Universe is a Strange Place - Ford/MIT Nobel Laureate Lecture Series 3/7/2005

    1:26:26

    Physics professor and Nobel Laureate Frank Wilczek gives the seventh and final lecture in the Ford/MIT Nobel Laureate Lecture Series, on March 7, 2005. Wilczek shared the 2004 Nobel Prize in Physics with David J. Gross and H. David Politzer for the discovery of asymptotic freedom in the theory of the strong interaction.”

    In his lecture Wilczek explores what we know and what we don’t know about the universe, always underscoring his feelings about how strange and beautiful this world we live in is. He presents two questions: What is the dark stuff? and How do you think about such a question? In the quest to understand such mysteries, Wilczek believes we need to demand more beautiful equations.

    The Q&A session focuses on his personal experience of winning the Nobel Prize and the 30+ somewhat frustrating years he spent waiting for it, once he and his colleagues (fellow graduate students at Princeton University) recognized the real significance of their find, back in 1972.


    About the Ford/MIT Nobel Laureate Lecture Series:

    In 1997 the Ford Motor Company engaged MIT in a strategic partnership to address a set of 21st century challenges facing the automotive industry. Through this innovative program, the Nobel Laureate Lecture Series was introduced in 2000 and featured local and international Nobel Laureates leading provocative discussions in economics, physics, chemistry, physiology, medicine, and peacemaking. Seven lectures were held from 2000 to 2005 at MIT and were organized by MIT's Community Services Office, Lecture Series Committee, Graduate Student Council, Industrial Liaison Program, Undergraduate Association, and the Office of the Chancellor.

    11:06

    The Universe. Infinite vastness. Unknown planets. Unexplored objects. This is how many videos that deal with space begin. But let's be honest, it also hits the nail on the head. The universe remains probably the greatest mystery of mankind. It is infinitely large and holds secrets in the same amount. Anyone who looks at the stars sees in principle only the surface of what is waiting out there. But since every day scientists and researchers are busy uncovering and solving the numerous mysteries of the universe, we can justifiably claim that we are getting a little bit smarter every day. And what does this lead to? In the end, only to more question marks and mysteries. We present to you eight of the currently greatest mysteries of outer space, which puzzle researchers and will surely leave you with a wrinkle on your forehead.

  • Exploring an Unbelievable New Universe - How Can the Universe be Infinite and Expanding?

    50:41

    If the universe was infinite the early universe must also be infinite (because the universe can never expand at an infinite rate) and, assuming all of the universe has matter, must have contained an infinite amount of matter. Look at a black hole, it is infinitely dense and does not have infinite energy.

    ----------------------------------------------------------------------------------
    OVERVIEW:

    In a profoundly informative and deeply optimistic discussion, Professor Michio Kaku delivers a glimpse of where science will take us in the next hundred years, as warp drives, teleportation, inter-dimensional wormholes, and even time travel converge with our scientific understanding of physical reality. While firing up our imaginations about the future, he also presents a succinct history of physics to the present.
    ----------------------------------------------------------------------------------
    MICHIO KAKU:

    Dr. Michio Kaku is the co-founder of string field theory, and is one of the most widely recognized scientists in the world today. He has written 4 New York Times Best Sellers, is the science correspondent for CBS This Morning and has hosted numerous science specials for BBC-TV, the Discovery/Science Channel. His radio show broadcasts to 100 radio stations every week. Dr. Kaku holds the Henry Semat Chair and Professorship in theoretical physics at the City College of New York (CUNY), where he has taught for over 25 years. He has also been a visiting professor at the Institute for Advanced Study as well as New York University (NYU).
    ----------------------------------------------------------------------------------
    TRANSCRIPT:

    My name is Professor Michio Kaku. I’m a professor of theoretical physics at the City University of New York and I specialize in something called string theory. I’m a physicist.
    Some people ask me the question, “What has physics done for me lately? I mean, do I get better color television, do I get better internet reception with physics?” And the answer is yes. You see, physics is at the very foundation of matter and energy. We physicists invented the laser beam, we invented the transistor. We helped to create the first computer. We helped to construct the internet. We wrote the World Wide Web. In addition, we also helped to invent television, radio, radar, microwaves, not to mention MRI scans, PET scans, x-rays. In other words, almost everything you see in your living room, almost everything you see in a modern hospital, at some point or other, can be traced to a physicist.

    Now, I got interested in physics when I was a child. When I was a child of eight, something happened to me that changed my life and I wanted to be part of this grand search for a theory of everything. When I was eight, a great scientist had just died. I still remember my elementary school teacher coming into the...

    Mankind has always been intrigued by the mysteries of deep space. Since the discovery of the telescope, astronomers have made huge steps into understanding the origin of the known cosmos, however, even after so many years, we are finding things in deep space that no one has seen before.

    On June 26th 2020 something mysterious occurred when four strange objects were identified by the radio telescope Australian Square Kilometre Array Pathfinder. These seem unlike any other astronomical objects ever seen before and ignited a spark of interest in the astronomical and space community.

  • How did the Universe form - out of nothing?

    3:25

    Check out Part II of this video here: -- How did the universe form? How did the Universe come from nothing? If you were to get rid of every “thing” in a certain part of space – all the planets, stars, atoms, particles, and even light and radiation… that space would still have weight – it would weigh something.

    It turns out that what we think of as “nothing” is NOT nothing. It is something. Space is bubbling with virtual particles that pop in and out of existence. (Quantum Fluctuations). These particles do this in a time scale so short that the laws of physics forgives this creation of these ghost particles that seem to arise from nothing. The laws of quantum mechanics allow this.

    The empty space within a proton represents 90% of the mass of the proton. And since most of our physical world is made up of protons and neutrons, this so called “empty space” inside them is what gives us mass.

    Here is the analogy – a zero represents nothing right? But a zero can also be represented by the number 1 million plus negative one million:
    1,000,000 + (-1,000,000) = 0
    The above equation is the key to understanding how our universe began. The total energy of the universe is 0, or “nothing” …however, at the beginning of the universe the zero spontaneously divided into 1 gazillion megawatts of energy, and negative 1 gazillion megawatts of energy.

    The total energy was still zero, but it was divided into these two numbers. The positive energy is represented by all the matter you can see in the universe – stars, planets, particles, radiation…
    …Because energy is equivalent to mass using Einstein’s famous equation E=MC(2)

    And what about the negative energy – where is that? That negative energy is in the form of gravity. The universe is flat. It is in perfect balance. The negative energy of gravity cancels out the positive energy of matter.

    Like my favorite character from the Matrix says…It is symphony of mathematical precision…the universe has a total energy of precisely zero. But it has manifested itself into something rather than nothing.

    Is our Universe one of many?

    The idea of parallel universes, once consigned to science fiction, is now becoming respectable among scientists – at least, among physicists, who have a tendency to push ideas to the limits of what is conceivable.

    In fact there are almost too many other potential universes. Physicists have proposed several candidate forms of multiverse, each made possible by a different aspect of the laws of physics.

    The trouble is, virtually by definition we probably cannot ever visit these other universes to confirm that they exist. So the question is, can we devise other ways to test for the existence of entire universes that we cannot see or touch?

  • What came before the Big Bang? How to get a Universe from no space, no time, no matter

    6:56

    Quantum Creation – what came before the big bang - the mechanism of a universe out of NO-thing - no matter, no space, and no time. Ancient Greek cosmologist Parmenides said “Nothing comes from nothing.” He was likely referring to the law of conservation of energy, that no new energy can be created. This is true and is a scientific fact even today. So how could the Universe come from nothing?

    Since the discovery of quantum physics and relativity, we have discovered a flaw in this argument that allows the creation of something from truly nothing. The Universe indeed had a beginning about 13.8 billion years ago, with the Big Bang. But what was there before the Big Bang? How did the universe come about from nothing. The flaw that we have uncovered in Parmenides original argument of “nothing comes from nothing” is that gravity has negative energy. And matter has positive energy.

    In a closed universe, a spontaneous splitting of 0 energy into an equal amount of positive energy and negative energy would not violate any conservation laws, because no new energy would have been created. And in quantum mechanics, anything that is not forbidden by conservation laws has a non-zero probability of occurring.

    But then we did not start with nothing. We started with the vacuum of physics, which has virtual particles that come in and out of existence, over very short periods of time. it has a weight and can be scientifically measured. So this is not nothing.

    So a more fundamental question is can a universe really be created with truly nothing – that means no-thing – no space, no matter, no time, no nothing? To answer this question, let’s work our way back from where we are now.

    If you solve Einstein’s equations for a universe like ours, you discover that it describes a universe that is either contracting or expanding. At the beginning of the big bang, it has a finite size, below which you cannot go any smaller. How does an explosion like the big bang occur from this finite size universe? In late 1979, a Stanford physics postdoc named Alan Guth offered an explanation for this bang or explosion. He showed that using the theories in particle physics, at extremely high energies — much higher than we could ever create in a lab — a special state of matter turns gravity upside down, causing it to be repulsive rather than an attractive force.

    A patch of space that contains even a tiny bit of this unusual matter, much smaller than the size of an atom, could repel itself so violently that it would blow up. And expand to a huge size. This would have happened for a very short time, a tiny fraction of a second, because this repulsive force quickly decays into the attractive force of gravity we see today. But this short period of time is enough to cause the “bang” in the big bang.

    So now we are at the Big Bang. We have a finite size universe with extremely high energy density that exploded in a brief inflationary period, and caused the big bang. Now, let’s go back further…the question now is how did a zero-size universe (a nothing) become Guth’s finite size universe.

    Physicist Alexander Vilenkin of Tufts University published a paper in 1984 that showed how this was possible using currently known laws of quantum mechanics. And he originated the idea of something called Quantum Creation. He showed that there is some energy barrier that the zero-size universe had to overcome in order to become finite size. This is where a phenomenon called quantum tunneling comes into play. It turns out that there is a probability, not very large, but a non-zero probability.

    Quantum tunneling is a real phenomenon that can be measured and is known to exist. Quantum mechanics shows that particles are waves of probabilities – and these waves have a non-zero probability of showing up spontaneously outside a barrier. This is how for example, an electron or even atom behind a barrier has a small probability of showing up on the other side of the barrier. Our zero-size universe can, through the process of quantum tunneling, become a finite size universe.

    And once it does that, then Guth’s cosmic inflation occurs, triggering the Big Bang. Then Einstein’s laws take over, and the universe’s expanding journey begins. And 13.8 billion years later, we observe the universe as we do today. So quantum mechanics gets you from zero size to a finite size, and then to the Big Bang. And then general relativity can get you from there to where we are today.

    And what triggered all this? In quantum physics, events do not necessarily have a cause, just some probability.
    So there is some probability for the universe to pop out of “nothing. If it is true, our existence had the humblest beginning of all - from nothingness itself.

    But you are still not starting with nothing, because you have to start with the laws of quantum mechanics. Where did these laws come from?

    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!

    Conformal Cyclic Cosmology is a story of the origin and the end of our universe from great mathematical physicist Sir Roger Penrose. It’s goes like this: the infinitely far future, when the universe has expanded exponentially to to an unthinkably large size, and every black hole and particle has decayed into faint radiation .... that infinite stretch of space and time is identically the SAME THING as the infinitesimal and instantaneous big bang of a new universe, and our universe is just one in an endless chain.

  • Lawrence Krauss - Life, the Universe, and Nothing: A Cosmic Mystery Story

    1:17:35

    Webcast sponsored by Irving K. Barber Learning Centre and hosted by the Vancouver Institute. Lawrence Krauss' work has been primarily in theoretical (as opposed to experimental) physics, and he has published research on a great variety of topics within that field. Krauss is a renowned cosmologist and popularizer of modern science and director of the Origins Project at Arizona State University. Hailed by Scientific American as a rare public intellectual, he is the author of more than three hundred scientific publications and 8 books, including the bestselling The Physics of Star Trek, and the recipient of numerous international awards for his research and writing. He is an internationally known theoretical physicist with wide research interests, including the interface between elementary particle physics and cosmology, where his studies include the early universe, the nature of dark matter, general relativity and neutrino astrophysics. His soon to be published book, A Universe From Nothing: Why There Is Something Rather Than Nothing is already garnering strong reviews. Exploring the scientific advances that provide insight into how the universe formed, Krauss ultimately tackles the age-old assumption that something cannot arise from nothing by arguing that not only can something arise from nothing, but something will always arise from nothing.

  • Why does the universe exist? | Jim Holt

  • A Quantum Beginning for a Two-Sided Universe with Dr. Neil Turok

    1:5:57

    How did it all begin? How did this universe in which we live come to be? The story begins in the early 20th century with Georges LeMaitre who originated the concept that an expanding universe could be extrapolated back to a point. Then came the observations of Edwin Hubble that indicated rather clearly that the universe was indeed expanding. Then there were other discoveries, such as the cosmic microwave background radiation which is literally the afterglow of the big bang. 

    But there are mysteries still. There comes a point where we can no longer study the big bang directly, a point where everything becomes opaque. This and other questions have led to a number of different models for just how the big bang played out. My guest Neil Turok specializes in the physics of the early universe, and unraveling just what happened.

    The cyclic universe theory was considered by Albert Einstein. A new cyclic universe theory was proposed by Dr. Neil Turok and Paul Steinhardt. What is the antiuniverse? Is there an antiuniverse?

  • Deep Space Anomalies, Scientists Have Discovered Something Far Beyond Our Solar System

    29:50

    This is certainly one of the most amazing deep space discoveries ever made. The ultimate goal of Astronomers has always been to find unmistakable signs of current life on a planet beyond Earth and it seems like they might have done just that. Exoplanets have been discovered recently that show all the signs of sustaining life, the next big question is...….can they support us. With major leaps forward in space technology we might soon discover something hardly anyone expected.

  • Universe: Beyond the Millennium - Stars

    50:19

    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.

    Stars, scientific studies of our sun and surrounding stars are revealing discoveries that link electric and magnetic weather patterns of the sun with storms that rage on the earth. Similarly, viewers learn how the sun's electro-magnetic properties can close the Toronto Stock Exchange and turn off all the lights in New York City.

    In five billion years, our nearest start, the sun, will die, swelling and becoming a red giant. The heat will be so intense the oceans will boil. Our planet will be scorched beyond recognition. The crust will melt, the surface will become an ocean of molten rock, all life will end, in the ultimate armageddon.

  • We have no idea about the universe | Daniel Whiteson | TEDxSanFrancisco

    18:10

    There are huge yawning voids in our basic notions of how the world works.

    Physicist Daniel Whiteson discusses how we're in an age of precision ignorance when we know very well that we know very little about the universe. The first step in making discoveries is embracing our ignorance.

    Whiteson is a Professor of Physics and Astronomy at UC Irvine. He is also the co-author of “We Have No Idea,” a light-hearted look at the open mysteries of the universe, and co-host of the podcast “Daniel and Jorge Explain the Universe.”

    Whiteson’s research is in the field of experimental high energy physics. He is interested in probing the structure of matter and the nature of its interactions at the very smallest scales, to understand the fundamental nature of our universe. Whiteson is part of the ATLAS collaboration, which built, maintained, and collects data from the ATLAS experiment at the Large Hadron Collider, This is where the Higgs Boson was discovered.

    Filmed at #TEDxSanFrancisco #DareToKnow on October 3rd, 2019, at the Herbst Theatre.

    #Astronomy #Physics #Astrophysics #Universe Daniel Whiteson has a desire to understand the fundamental nature of our Universe. So naturally, he is a Professor of Physics at UC Irvine. Whiteson is also the co-author of

    “We Have No Idea”, a light-hearted look at the open mysteries of the Universe, and co-host of the podcast “Daniel and Jorge Explain the Universe. Whiteson and his colleagues have also created popular comics like “What’s in the data? The Higgs Boson Explained” and “True Tales of Dark Matters” which were both featured on PBS. Whiteson received his PhD from UC Berkeley and received a postdoctoral fellowship at the University of Pennsylvania. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at

  • 5 Theories About What Lies Outside The Observable Universe!

    10:50

    About 13.75 billion years ago, our universe as we know it today was created. Shortly thereafter, the primordial light began to shoot through the cosmos and spread throughout the entire early universe. At this time the universe itself also expanded. However, the inflation of the universe slowed down after the first initial eruption, but since then the rate of expansion has been steadily increasing due to the influence of increasing dark energy. In essence, the cosmos has been growing at an ever-increasing rate since its creation. Physicists and mathematicians have been studying the nature of the universe for hundreds of years, trying to solve the mysteries it contains. But there are some scientists who go one step further into the unknown by thinking about what lies beyond the boundaries of our universe. Is it possible that there is something else beyond the existence of our universe? Other universes, worlds whose existence we can only guess at? That could well be the case. Here are five theories about what this something could be and what clues there are for the various theories.

  • Did the Universe Come From Nothing? • An Outsiders view of Quantum Field Theory and Dark Energy

    10:54

    Today, we are talking about nothing! Absolutely nothing. Did the Universe Really Come From Nothing? A few episodes ago, we asked the question, “What Happened before the Big Bang?” If you haven’t yet listened to that podcast, be sure to do so! I stuck mostly with Stephen Hawking’s take on space-time and focused on the emergence of time itself. But the time has come to go deeper. We are getting our hands messy today with quantum physics. We are going to see if we can figure out why some scientists say that everything did indeed, come from nothing.

    The Block Universe Theory is one model of the universe which was created to describe the concept of time in a simple way. Basically: everything already happened, and it’s inside this ‘block.’ Thus, time is just another coordinate that can be plotted within this a-temporal block! I know, it’s crazy, and yet, it’s the most accepted way to talk about time (though not the ONLY way). ????

    Time is a construct that we humans invented to try and explain the changes and movements of the universe that are happening around us. Time is our way of trying to bring order to cosmic chaos. So, you could say that this series is me, trying to bring a little order to my understanding of time! Where did time come from? What is time? Where does time exist? What is the base unit of time? Why do we even need time? Why does time seem to slow down when something crazy happens or when you’re bored? How did time come to be? What about relativity and quantum mechanics? What the HECK is this thing we call TIME?! You’ll have the answers. Let’s kick into it.

    An Einstein-Minkowski Light Cone Diagram (Fig 9)

    A Minkowski spacetime light cone diagram shows the different causal regions corresponding to an event E= (0,0,0,0) at the origin. The timelike regions (inside the light cones) are regions where there can be a causal relationship between the event at the origin and an event within the timelike regions.

    Free Will in the Block Universe?

    Since Einstein‘s theories of special and general relativity were accepted by the scientific community, a good deal (perhaps most) of the specialists in this branch of physics have favored the world image called the block universe.

    A Debate over the Physics of Time

    Einstein once described his friend Michele Besso as “the best sounding board in Europe” for scientific ideas. They attended university together in Zurich; later they were colleagues at the patent office in Bern. When Besso died in the spring of 1955, Einstein — knowing that his own time was also running out — wrote a now-famous letter to Besso’s family. “Now he has departed this strange world a little ahead of me,” Einstein wrote of his friend’s passing. “That signifies nothing. For us believing physicists, the distinction between past, present and future is only a stubbornly persistent illusion.”

    The Planck Scale

    In the late 1890s, physicist Max Planck proposed a set of units to simplify the expression of physics laws. Using just five constants in nature (including the speed of light and the gravitational constant), you, me and even aliens from Alpha Centauri could arrive at these same Planck units.
