Caltech: The Quest of Gravitational Waves – B. Barish

Learn more about General Relativity at One Hundred: The Sixth Biennial Francis Bacon Conference held at Caltech and The Huntington Library, Art Collections and Botanical Gardens. Produced in association with Caltech Academic Media Technologies.  

PBS: Nucleosynthesis | Space Time

Joni Mitchell was right, we are stardust. Stars are our stellar alchemists. They spend their entire lifespan creating and molding elements. In their final moments, a supernova spreads these elements out into the universe, providing the building blocks for new stars, planets, and even us!  

MIT: Particles attract across long distances

A team of scientists from MIT has found a new kind of long-range interaction between particles, in a liquid medium, that is based entirely on their motions. And these interactions should apply to any kind of particles that move whether they be living cells or metal particles whirled by magnetic fields.  

American Museum of Natural History: 2016 Isaac Asimov Memorial Debate: Is the Universe a Simulation?

What may have started as a science fiction speculation—that perhaps the universe as we know it is a computer simulation—has become a serious line of theoretical and experimental investigation among physicists, astrophysicists, and philosophers. Neil deGrasse Tyson, Frederick P. Rose Director of the Hayden Planetarium, hosts and moderates a panel of experts in a lively …

Great Big Story: Growing Snowflakes For Science (and ‘Frozen’)

You may not know Dr. Kenneth Libbrecht by name, but if you’ve seen “Frozen,” you know his work. He’s a snowflake scientist (unofficial title) at Caltech and served as an ice crystal consultant for that “Let it Go” movie.  

Perimeter Institute for Theoretical Physics: Niels Bohr | Life Behind the Physics

Dr. Vilhelm Bohr, grandson of quantum science pioneer Niels Bohr, delivers a talk as part of Perimeter’s Institute’s Public Lecture Series.  

PBS Digital Studios: Space Time | Why is the Earth Round and the Milky Way Flat?

Our universe is not a very diverse place when it comes to shapes. Large celestial bodies become spheres, galaxies become discs, and there is little room for variation. Why is this? Well it turns out physics has some pretty strict rules when it comes to creating new planetary bodies. On this week’s Space Time, the …

TED: Allan Adams | What the discovery of gravitational waves means

More than a billion years ago, two black holes in a distant galaxy locked into a spiral, falling inexorably toward each other, and collided. “All that energy was pumped into the fabric of time and space itself,” says theoretical physicist Allan Adams, “making the universe explode in roiling waves of gravity.” About 25 years ago, …

PBS: Space Time | What’s Wrong With the Big Bang Theory?

There’s a problem with the Big Bang Theory. Now that we have a primer on the aspects of the Big Bang Theory that we know definitely happened, let’s look further into what we don’t yet know, and how the theory could progress in the future. Since there is a discrepancy between general relativity and quantum …

Columbia University: Astrophysicists & Neil deGrasse Tyson on LIGO

Neil deGrasse Tyson took the stage together with other astrophysicists at the Columbia University to speak after a historic result was revealed: the first direct detection of gravitational waves.  

Caltech: Ripples in Spacetime: Our New Window On the Universe

On February 23, 2016, Caltech and LIGO scientists held a panel discussion about the recent detection of gravitational waves and what this discovery will mean for our ongoing understanding and exploration of our universe. Speakers included President Thomas Rosenbaum, Fiona Harrison, Kip Thorne, Barry Barish, Mike Landy, Alan Weinstein, Mansi Kasliwal, Anamaria Effler, Rana Adhikari, …

Perimeter Institute for Theoretical Physics: Gravitational Waves: What Lies Ahead?

Perimeter Institute Director Neil Turok discusses the future of physics in the new era of gravitational wave astronomy.  

The Late Show with Stephen Colbert: Gravitational Waves Hit The Late Show

Brian Greene stops by to demonstrate an exciting new scientific discovery.  

World Science Festival: What will we learn from the detection of gravitational waves?

The discovery of gravitational waves is a landmark in physics history. It confirms predictions Einstein made over 100 years ago. But what other kinds of answers can this discovery bring? Gabriela González, spokesperson for the LIGO scientific collaboration, gives a brief insight into the implications this achievement has for the future of science.  

Perimeter Institute for Theoretical Physics: Ripple Effects: A Forum on Gravitational Waves

On Feb. 11, 2016, a panel of researchers from Perimeter Institute for Theoretical Physics discussed the meaning and implications of LIGO’s landmark announcement regarding the detection of gravitational waves. The panel includes Perimeter Director Neil Turok, along with Faculty members Asimina Arvanitaki, Latham Boyle, and Luis Lehner. Science journalist Kate Lunau moderated the discussion.  

Nature: Gravitational waves: A three minute guide

It’s almost exactly a century since Einstein first predicted the existence of gravitational waves. In this Nature Video we find out what they are, and how scientists are searching for them, in an attempt to prove Einstein right.  

National Science Foundation: LIGO detects gravitational waves

Scientists at Washington’s National Science Foundation and Moscow State University have confirmed the discovery of Albert Einstein’s gravitational waves. The breakthrough, possibly the biggest in physics in a century, could be the key to new understanding of the universe. “Ladies and gentlemen! We have detected gravitational waves, we did it!,” LIGO laboratory executive director David …
