But it’s taken some of the most incredible ingenuity of the past half-century to figure out how that out. All so that today I can teach you how to simulate a very very small universe.

    How Will We (Most Probably) Discover Extraterrestrial Life?

    PBS Member Stations rely on viewers like you. To support your local station, go to:http://to.pbs.org/DonateSPACE Sign Up on Patreon to get access to the Space Time Discord! https://www.patreon.com/pbsspacetime The first discovery of extraterrestrial life will almost certainly NOT be when it visits us, nor when we visit it. It won’t be when we see it’s stray TV signals. It’ll be in the excruciatingly faint changes in the color of alien sunsets glimpsed hundreds of light years away. Today we’re going to talk about the first such hint, why it's probably not aliens, and why there’s a tiny chance that it still might not not be aliens.

Why? Because we can use them as futuristic power generators, galactic-scale bombs, and portals to other universes. Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Leonardo Scholzer, Yago Ballarini, & Pedro Osinski Directed by: Andrew Kornhaber Executive Producers: Eric Brown & Andrew Kornhaber End Credits Music by J.R.S. Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0Q Black holes are self-sustaining holes in the fabric of spacetime. Space at the event horizon cascades downwards, dragging more space behind it, sort of like how water drags itself near the edge of a waterfall. In a Kerr black hole, space above the event horizon is dragged around in a circle - so less waterfall and more whirlpool. Water spiraling down a drain in a flat sink doesn’t know about the hole - it only knows about the motion of the water around it. In fact it’s possible to construct a black hole in general relativity rotating or otherwise - without any mass. Warp spacetime so it looks like the exterior of a black hole, and that warping will persist. So what is rotating? Spacetime is rotating.

    What’s On The Other Side Of A Black Hole?

At the event horizon - the ultimate point of no return as you approach a black hole - time and space themselves change their character. We need new coordinate systems to trace paths into the black hole interior. But the maps we draw using those coordinates reveal something unexpected - they don’t simply end inside the black hole, but continue beyond. In these maps, black holes become wormholes, and new universes lie on the other side.

    Dark Forest: Should We NOT Communicate with Aliens?

    Check out the Space Time Merch Store https://www.pbsspacetime.com/shop In 1974 we sent the Arecibo radio message towards Messier 13, a globular cluster near the edge of the Milky Way, made up of a few hundred thousand stars. The message was mostly symbolic; we weren’t really expecting a reply. Yet surely other civilisations out there are doing the same thing. So, why haven’t we heard anything? What if the silence from the stars is a hint that we shouldn’t be so outgoing? What if aliens are deliberately keeping quiet for fear that they might be destroyed?

This insane hypothesis is getting closer to reality, according to the papers in today’s space time journal club. Hosted by Matt O'Dowd Written by Matt O'Dowd Graphics by Leonardo Scholzer & Adriano Leal Directed by: Andrew Kornhaber Executive Producers: Eric Brown & Andrew Kornhaber End Credits Music by J.R.S. Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0Q Thanks to LIGO we’ve now seen black hole mergers, but there was some striking surprises. For one thing, many of the merging black holes were too massive to have been formed by the collapse of stellar cores. That is if our understanding of stellar evolution is half as good as we think it is. This led astrophysicists to think about new ways to produce black hole mergers. Here’s the most awesome possibility: what if black hole mergers actually occur in orbit around supermassive black holes, embedded deep in the whirlpools of searing gas that surround some of these monsters? Today on Space Time Journal Club we’ll be looking at a pair of 2019 papers that talk about this possibility. We have Yang et al., which predicts the properties of black holes that merge this way, and McKernan et al. which proposes a way for us to actually test this hypothesis.
