Space Time explores the outer reaches of space, the craziness of astrophysics, the possibilities of sci-fi, and anything else you can think of beyond Planet Earth with our astrophysicist host: Matthew O’Dowd.
For all business inquiries and sponsorship opportunities please reach out to: pbsspacetime@lighthouseagents.com
Matt O'Dowd spends his time studying the universe, especially really far-away things like quasars, super-massive black holes, and evolving galaxies. He uses telescopes in space to do it. Matt completed his Ph.D. at NASA's Space Telescope Science Institute, followed by work at the University of Melbourne and Columbia University. He's now a professor at the City University of New York's Lehman College and an Associate at the American Museum of Natural History's Hayden Planetarium.
Previous host Gabe Perez-Giz is an astrophysicist who studies black hole physics. He received his Ph.D. from Columbia University and also hosted PBS Infinite Series.

We can seek the answer in the chemistry of the early earth, or in the biology of the first cell. In fact our friends at PBS Eons and It’s OK to be Smart will do just that in companion videos to this one. But we all know that chemistry and biology are just applied physics. So can we approach the question of the origin and the very nature of life from the point of view of physics? We’re sure going to try.Hosted and written by Matt O'DowdProduced by Rusty WardGraphics by Grayson BlackmonAssistant Editing and Sound Design by Mike Petrow and Linda HuangMade by Kornhaber Brown (www.kornhaberbrown.com)Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasAnton LifshitsJoey RednerQuasarTambe BarsbayMayank M.

Or in physics-ese, it’s the maximally extended Penrose diagram of a Kerr spacetime. And in english: when you solve Einstein’s equations of general relativity for a rotating black hole, the universe does not come to an abrupt halt at the bottom of the gravitational pit. Instead, a path can be traced out again but you do not end up in the universe that you started in. Like I said, it’s a map of the multiverse.Hosted by Matt O'DowdWritten by Matt O'DowdGraphics by Leonardo Scholzer, Yago Ballarini, and Pedro OsinskiDirected by: Andrew KornhaberCamera Operator: Bahaar GholipourExecutive Producers: Eric Brown and Andrew KornhaberEnd Credits Music by J.R.S.

How to Communicate Across the Quantum Multiverse
lundi 19 octobre 2026 • Durée 22:45
Check Out Megawow on PBS Kids: https://youtu.be/meU4f31gqYI Uploaded 10-08-21In the Many Worlds interpretation of quantum mechanics, the universal wavefunction is the reality, encompassing all possible histories and futures and all exist. But we are only sensitive to a slice of the wavefunction corresponding to our “world”, and due to the superposition principle our world can happily do its thing unperturbed by other parts of the wavefunction - other “ripples,” or worlds. And while it may seem like it would be physically impossible to have any connection between worlds, it may turn out to be entirely possible to communicate between them.

It expresses the fundamental limit on the knowability of our universe. We’ve discussed it in our early videos on quantum mechanics, but it’s time we looked a little deeper. See, the apparent weirdness of the uncertainty principle hints at the even weirder underlying reality that gives rise to it. The universe we experience seems to be constructed of singular particles with well-defined properties. But this intuitive, mechanical reality is emergent from underlying reality in which the particles that form matter arise from of the combination of an infinity of possible properties. And forget matter - the vacuum itself is the sum of infinite possible particles. If we fully unravel this idea we’ll be on the verge of tackling things like Hawking radiation. But as you’ll see today, in that unraveling we are led, unavoidably, to Heisenberg’s uncertainty principle.Hosted by Matt O'DowdWritten by Graeme Gossel and Matt O'DowdProduced by Rusty WardGraphics by Kurt RossAssistant Editing and Sound Design by Mike PetrowMade by Kornhaber Brown (www.kornhaberbrown.com)Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasWilliam James SidisQuasarTambe BarsbayMayank M.
