Brian Greene on the first-ever image of a black hole from the Event Horizon Telescope
 
03:24
On April 10, 2019, scientists from the Event Horizon Telescope announced a result that will change our understanding of the universe: the first-ever image of a black hole's event horizon, the point at which light can no longer escape the black hole's gravitational pull. Using linked telescopes from around the globe, EHT's team measured the ring of photons circling the black hole at the center of galaxy Messier 87, 55 million light-years from Earth. The observations further confirm Einstein's general theory of relativity. For more info about how this amazing observation was made, watch our long form program "How Do You Observe a Black Hole?

What is the Holographic Principle?
 
03:00
When Stephen Hawking elegantly described the relationship of quantum mechanics with black holes, he inadvertently opened the door to a radical possibility: that our universe, as we know it, is like a hologram. Science historian Peter Galison and leading physicists Brian Greene and Cumrun Vafa explain how the resilient nature of information combined with the behavior of event horizons suggests that the three dimensions of reality we observe may in fact be a two-dimensional information structure "painted" on some sort of cosmological horizon.

Brian Greene and Alan Alda Discuss Why Einstein Hated Quantum Mechanics
 
15:14
Albert Einstein was not a fan of quantum mechanics. He was annoyed by the uncertain, random nature of the universe it implied (hence the famous quote "God does not play dice with the universe"). So, Einstein tried to develop a unified theory that would circumvent what he saw as quantum mechanics' flaws. In this excerpt from the 2014 World Science Festival Program Dear Albert, Alan Alda and Brian Greene discuss Einstein's relationship with the "unruly child" of quantum mechanics, and how the famed physicist came up with the Special Theory of Relativity.

Leonard Susskind Takes On Hawking Radiation
 
04:58
Stephen Hawking's premise was sound; his math irrefutable. As matter falls into a black hole, quantum events cause it to emit particles. These particles—what became known as Hawking Radiation—lead to the eventual evaporation of the black hole, and any information about the matter that fell in would be lost forever. But for physicists Leonard Susskind and Gerard ’t Hooft, something didn't sit right. In fact, it seemed to go against the very laws of physics—a contradiction which ultimately led to the radical possibility of the knowable universe as encoded information. They discuss with moderator John Hockenberry the delicate challenges of arguing with a man whose theories were for all intents and purposes "unassailable."

Brian Greene Introduces the Theory of General Relativity
 
05:03
Ever wanted to understand Einstein’s theories of relativity, but didn’t know where to start? Let Brian Greene introduce you to you the Theory of General Relativity with an alluring metaphor. Physicist Brian Greene explains how Albert Einstein, wrestling with how exactly gravity works, originally formulated the general theory of relativity. The landmark breakthrough provided the first unified description of gravity as a geometric property of space and time. It also laid the foundation for understanding more bizarre properties of the universe—like the curvature of spacetime, string theory, and the possibility of multiple, hidden dimensions of the universe.

What is the Poincare Conjecture?

Is it possible to deduce the shape of the universe without stepping outside of it? Henri Poincaré thought so. Similar to how the Greeks were able to discern the spherical nature of the earth (and even its rough diameter) using mathematics, he proposed that we should be able to make conclusions about our universe. Stanford University mathematician Keith Devlin explains the Poincaré Conjecture, which became a legendary problem in mathematics, with the help of a short animation.

Quantum Levitation: A Rare Look at Quantum Mechanics in Action
 
02:30
In a world where seeing is believing, one of the chief disadvantages of quantum physics is that it’s largely invisible. The wonderfully bizarre rules that allow a vanishingly small particle to exist in two places simultaneously, for instance, usually apply at scales too small to be seen by the naked eye. But not always. Here, physicist Boaz Almog of Israeli’s Tel Aviv University gives audience members of the 5th Annual World Science Festival Gala Celebration a rare macroscopic view of the magical properties of quantum mechanics. Sharing the stage with fellow physicist Brian Greene, Almog conducts the first public demo in the U.S. of an ethereal phenomenon he calls quantum levitation, sending a thin, super-chilled wafer zipping around a circular track like a miniature flying saucer. He also freezes the wafer in mid-air, as though trapped in a vat of invisible glue. How? Watch as Greene explains.

Can superfluid be the link to understanding dark matter?

The behavior of dark matter, by nearly all accounts, is exceedingly odd: It influences the movement of so-called normal matter through gravity, but refuses to interact via any of the other known forces. Physicist John Khoury has an idea why. According to his theory, dark matter acts like a superfluid, a matter state in which lots of individual particles behave as one.

The Unreasonable Effectiveness of Mathematics
 
04:36
Basic researchers working in pure mathematics often develop fundamental laws, even entire branches of math, without any specific application in mind. Yet, as Mario Livio points out here, many of these posited laws turn out—sometimes centuries later—to perfectly describe the behavior of the real world with remarkable precision. This phenomenon was best articulated in the early 1900s by the Hungarian physicist Eugene Wigner as the "unreasonable effectiveness of mathematics." And it begs the question: What gives mathematics this power? Cognitive scientist Marvin Minsky provides an interesting, if wry, answer: if it were not the case, there would be no one to notice.

Nobel Prize-winning physicist William Phillips explains the daunting—possibly impossible—task of reaching the coldest temperature known.

Mind Control: Introducing BrainGate
 
03:43
Moving objects with one's mind is the fodder of sci-fi, magic tricks, and futuristic visions. But John Donoghue explains how, in some ways, such dreams are a reality. He's developing revolutionary technology that "reconnects the brain to the outside world" in patients who are completely paralyzed. Using transplants that detect thoughts and translate them into actionable bits of code, the pioneering neuroscientist describes a new era in which mind and machine are interacting in surprising ways—from playing Pong to completing complex daily actions, just by thinking about it.

Like us down here on Earth, the astronauts on the International Space Station can't work 24 hours a day. So what do they do up there for fun? Luckily, the zero gravity environment gives them a unique opportunity to goof around, as well as learn some important lessons in newtonian dynamics.

Mathematician W. Hugh Woodin Explains Continuum Hypothesis
 
06:18
Mathematician W. Hugh Woodin has devoted his life to the study of infinity, attempting to solve the unsolvable. Doing so does require some mental gymnastics and willingness to change your mind if the evidence points in another direction. Listen to him explain his work on the continuum hypothesis and why studying the infinite is so difficult.

Timeless Time in the Quantum World

In our world, it wouldn't be normal for a broken teacup to pull itself together again in the next moment. But in the quantum world, the "flow" of time does not seem to exist. Physicists Fay Dowker, Roger Penrose, and Frank Wilczek explain this strange yet fundamental phenomenon in a clip from the 2009 World Science Festival program "Time Since Einstein."

Brian Greene asks Richard Dawkins ... Does God Exist?
 
04:33
Richard Dawkins and Brian Greene discuss their notions on God in the context of evolution and science. Does one exist? Is God the same as science and physics but with different nomenclature, as Brian Greene implies? Or is God "the physicist to end all physicists," one that Richard Dawkins says demands an explanation?

A Mind Roused by Music
 
03:48
A clip from the documentary Alive Inside shows us a man named Henry who suffers from dementia. Eyes cast downward, he has trouble answering the simplest yes or no questions. Immanuel Kant once called music “the quickening art”, and nowhere else is it more apparent than when Henry is presented with music. He regains his mental acuity, and the difference is like night and day.

The Teenage Brain Is Primed For Addiction
