The purpose? To detect life on a planet based on measurements by a space probe. The experiment was successful, and abundant life was unequivocally confirmed. That planet? The Earth. Now, a quarter century later, we’re on the verge of conducting that same experiment on a world orbiting another star.Written by Drew Rosen and Matt O’DowdHosted by Matt O’Dowd Produced 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 NicklasRichard SenegorQuasarTambe BarsbayMax LevineMayank M.

Let’s figure this out. If black holes exist – which, apparently, they do – they contradict other theories in physics as sacred as general relativity. They cause all sorts of problems with quantum theory, which we’ve talked about and will review in a sec. But they also present an apparent conflict with the notion of entropy and the second law of thermodynamics. It was while pondering that conflict that Jacob Bekenstein realized an incredible connection between black holes and thermodynamics. His insight launched an entire new way of thinking about the universe in terms of information theory, and ultimately led to the holographic principle. Which I promise we’re getting to and we’re almost there. We just need to understand string theory first and to understand that, you’re going need to know about why Black Holes contain most of the universe’s entropy.Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangAnton LifshitsCoolAsCatsDavid NicklasFabrice EapQuasarDean FuquaMark RosenthalMayank M.

We knew we’d see things previously thought impossible. And we just did - an object on the boundary between neutron stars and black holes, which promises to reveal the secrets of both.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 KornhaberPrevious Episodes Referenced:Ligo’s First Detection of Gravitational Waves: https://www.youtube.com/watch?v=gw-i_VKd6WoThe Future of Gravitational Waves: https://www.youtube.com/watch?v=eJ2RNBAFLj0How to build a black hole https://www.youtube.com/watch?v=xx4562gesw0&vl=enStrange Stars - https://www.youtube.com/watch?v=u4RNGRyzt10Special Thanks to Our Patreon SupportersBig Bang SupportersRobert DoxtatorAhmad JodehCaed AldwychRadu NegulescuAlexander TamasMorgan HoughJuan BenetFabrice EapDavid NicklasQuasar SupportersAlec S-LChristina OegrenMark HeisingVinnie FalcoHypernova Supporterswilliam bryanJulian TyackeSyed AnsarJohn R.
