Physics concerns what we can say about Nature.” Well it turns out that if we pay attention to this subtle difference, some of the most mysterious aspects of nature make a lot more sense.Sign Up on Patreon to get access to the Space Time Discord!https://www.patreon.com/pbsspacetimeSign up for the mailing list to get episode notifications and hear special announcements!https://mailchi.mp/1a6eb8f2717d/spacetimeSearch the Entire Space Time Library Here: https://search.pbsspacetime.com/Hosted by Matt O'DowdWritten by Matt O'Dowd Post Production by Leonardo Scholzer, Yago Ballarini, Pedro Osinski, Adriano Leal and Stephanie FariaGFX Visualizations: Ajay ManuelDirected by Andrew KornhaberAssociate Producer: Bahar GholipourExecutive Producers: Eric Brown and Andrew KornhaberExecutives in Charge (PBS): Adam Dylewski, Maribel Lopez Director of Programming (PBS): Gabrielle Ewing Spacetime is produced by Kornhaber Brown for PBS Digital Studios.This program is produced by Kornhaber Brown, which is solely responsible for its content.© 2022 PBS.

We somehow persist the gradual heating of our Sun and the evaporation of our oceans. Our descendants cling to existence through countless generations we watch the Andromeda galaxy merge with the Milky Way, forming a vast elliptical galaxy. We seek refuge in the outer solar system as the Sun finally expands into a red giant – twice! And finally our heirs or successors find new homes among the stars after the Sun’s final death and transformation into a dim white dwarf.Hosted by Matt O'DowdWritten by Drew Rosen and Matt O'DowdGraphics 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 RednerFabrice EapQuasarTambe BarsbayMayank M.

Life will blossom in our path and the galaxy with shimmer with beautiful Earth-like orbs. Hmmm… maybe. This won’t sound so far fetched if we prove we can do it at least once. If we successfully terraform Mars.

But those settlements will need to be cocooned - shielded against the deadly cold, intense radiation, and the fatal lack of atmospheric pressure. Surely if we want to thrive on Mars – to make it into our second home – these settlers, or their descendants, will need to be able open the airlocks, shed their spacesuits, and step out onto a survivable surface. We’ll need to terraform Mars, as our first step in terraforming the galaxy.Red Iris Mars habitat by James Telfer: http://bit.ly/JamesTelferRedIrisWant Even More Great Space Content?

To support your local station, go to: http://to.pbs.org/DonateSPACEOne of the fundamental questions humanity has always asked is how big is our Universe? For much of human history, people believed that Planet Earth was the very center of the entire universe. And Earth is pretty big. But compared the rest of the universe, we are infinitesimally small. The animation in this video the Digital Universe data collection curated by the American Museum of Natural History. The software is used to visualize these datasets is OpenSpace, which is developed through a collaboration between AMNH, Linköping University in Sweden, New York University, and the University of Utah. The software and datasets are open source and are free to download and explore. https://www.openspaceproject.com/Credit: From the ESO Supernova to the end of the Universe at 00:52https://www.youtube.com/watch?v=hy2cxmHuEAsCredit: ESO/L.

It's part of a PBS miniseries called Stellar, done in collaboration with Diana Cowern from @physicsgirl and Joe Hanson from @It'sOkayToBeSmart. Over six episodes we travel to telescopes, go inside space research centers, and chat with amazing scientists. Next up is Joe's episode where he explores where life might be outside our solar system.Check out Joe’s episode here:https://www.youtube.com/watch?v=XoxGOL-Ow9wCheck out the other episodes in this series:The Quasar from The Beginning of Time | STELLARhttps://www.youtube.com/watch?v=cqCPn…Seeing a Black Hole with a Planet-Sized Telescope | STELLARhttps://www.youtube.com/watch?v=gUpKt…I Visited the First Gravitational Wave Detector!
