    All particles belong to two large groups: fermions like protons and electrons make everything we consider "matter", while bosons like photons and gluons transmit the fundamental forces. And that about covers the universe: matter moving through space and time under the action of forces. But what if we could create particles in between these two possibilities. Physics says these neither matter nor force anyons can exist, and they may have some pretty incredible uses. They’re called anyons.

The one just left of the Milky Way center in the constellation of Andromeda. That’s M31 – the Andromeda galaxy. It’s two and a half million light years away and host to a trillion stars. It has a beautiful spiral structure spanning its gently rotating disk 220 thousand light years in diameter, and a central bulge that hides a giant black hole that contains the mass of well over a hundred million Suns. Andromeda is also racing towards our galaxy at 110 km/s.Written and Hosted 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)Comments Matt responded to include:The Exoplanets Channelhttps://www.youtube.com/watch?v=-R9F2_D76TE&lc=UgzYOYV-1GsJrSwlmZ14AaABAgPatrick Horganhttps://www.youtube.com/watch?v=-R9F2_D76TE&lc=UgxB8ZoEtScJ4vFBSo94AaABAgAnd Springville High School’s AP Physics Class!Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasFaisal SaudAnton LifshitsJoey RednerQuasarTambe BarsbayMayank M.

    Why Is The World Returning To The Moon So Quickly?

    The Moon has been one of the most important theoretical stepping stones to our understanding of the universe. We’ve long understood that it could also be our literal stepping stone: humanity’s first destination beyond our atmosphere.

Schattenberg: https://www.youtube.com/channel/UCRl6-nb4iOnsij-vnpAjp0QImagine it: the observable part of our universe is 93 billion light years across, and that’s just a small fraction of the stuff created in our Big Bang. But in the eternal inflation picture, ours is just one among uncountable bubble universes. Bubbles that are continuously appearing and growing within a vastly larger spacetime that itself expands at an exponentially accelerating rate. A greater inflationary spacetime whose expansion never ends. We looked at the bizarre idea of eternal inflation in recent episodes – but we stopped short of exploring the full implications of this proposition. Those implications are, frankly, completely nuts.

    Can The Crisis in Cosmology Be EXPLAINED By Cosmic Voids?

    Two of the greatest mysteries in cosmology are the nature of dark energy and the apparent conflict in our measurements of the expansion rate of the early versus the modern universe that even dark energy can’t account for. Could both of these be explained by looking to a part of the universe that we’ve largely ignored so far? Could cosmic voids be driving the universe?

Om PBS Space Time
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: [email protected] 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. patreon.com/pbsspacetime
