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.

Previous Episode: The Misunderstood Nature of Entropy https://www.youtube.com/watch?v=kfffy12uQ7g Entropy is sometimes described as a measure of disorder or randomness. The second law of thermodynamics – the law that entropy must, on average, increase – has been interpreted as the inevitability of the decay of structure. This is … misleading. As we saw in our episode on the physics of life, structure can develop in one region even as the entropy of the universe rises. Ultimately, entropy is a measure of the availability of free energy – of energy that isn’t hopelessly mixed in thermal equilibrium. Pump energy into a small system and complexity can thrive..

    What if Singularities FAIL to Exist?

    Sign Up on Patreon to get access to the Space Time Discord & 10% Off All Merch! https://www.patreon.com/pbsspacetime It's not too often that a giant of physics threatens to overturn an idea held to be self-evident by generations of physicists. Well, that may be the fate of the famous Penrose Singularity Theorem if we're to believe a recent paper by Roy Kerr. Long story short, the terrible singularity at the heart of the black hole may be no more.

    What If The Cosmological Constant Wasn't Truly Constant?

    Weathered: Earth's Extreme is available globally at: https://to.pbs.org/WeatheredST or the PBS App (US Only) Check out the Space Time Merch Store https://www.pbsspacetime.com/shop We know that the universe is getting bigger. And we know that the speed that the universe is getting bigger is also getting bigger. The standard assumption is that the acceleration rate is itself constant, which will surely result in ultimate heat death. But a recent survey of primordial sound waves frozen into the way galaxies are sprinkled through the universe reveals that this fate is now in question. PBS Member Stations rely on viewers like you.

This time, people watched with anticipation as SpaceX launched its new Falcon Heavy rocket. This was the first test of a rocket that may one day send people across the solar system. The near-simultaneous landing of its two booster rockets was like something out of a sci-fi flick. It looked like the future. The subsequent view of a cherry-red Tesla Roadster drifting through space was like something out of a Douglas Adams novel. The landmark launch of the Falcon Heavy rocket is a milestone in a new space race. One not between nations, but instead between private companies. Is this the best thing for the future of human space travel?

To support your local station, go to: http://to.pbs.org/DonateSPACE We live in the stelliferous era. Somewhere between 10 and 1000 billion trillion stars fill the observable universe with light. But there was a time before the first star ignited. A time we call the cosmic dark ages. Check out the new Space Time Merch Store! https://pbsspacetime.com/ Support Space Time on Patreon https://www.patreon.com/pbsspacetime Need a Black Hole Refresher https://youtu.be/vNaEBbFbvcY #theuniverse #astrophyics #spacetime Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Aaron Havley Directed by Andrew Kornhaber Produced By: Kornhaber Brown In astronomy we study things that are very far away. It’s a powerful challenge because even the brightest objects are almost impossibly faint when you view them from the other side of the universe. But there’s an up side. If the light from some space object took billions of years to get to us then we see that object as it was billions of years ago. In this way we can peer back in time and literally see the past in motion. In fact we’re able to see some of the first stars and galaxies to ever form. But if we look beyond, both in distance and in time, there is … nothing. Darkness. For the hundred million years or so between the formation of the first atom and the formation of the first star there were no light sources in the universe. These were the cosmic dark ages. It’s a period of cosmic history rarely discussed because it’s hellishly difficult to observe. Fortunately scientists are devilishly clever. So what do we know about the time before stars?
