by PBS
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. 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.

The Heisenberg uncertainty principle tells us that the more precisely we try to define one property, the less definable is its counterpart. Knowing a particle’s location perfectly means its velocity is unknowable. But unmeasured properties are not just uncertain; they are undefined. Quantum mechanics seems to imply that ALL possible properties, paths, or events that could reasonably occur between measurements DO occur. Whether or not this is true, a mathematical description of this crazy idea led to the most powerful expression of quantum mechanics ever devised: Richard Feynman’s path integral formulation.Written and Hosted by Matt O’Dowd Produced by Rusty WardGraphics by Kurt RossMade by Kornhaber Brown (www.kornhaberbrown.com)Comments answer by Matt:Satya Prakashhttps://www.youtube.com/watch?v=ATcrrzJFtBY&lc=z12bv5hpgoyadn20522zfvo5eur2vftyy04Jakub Mintalhttps://www.youtube.com/watch?v=ATcrrzJFtBY&lc=z13pvhcyeyj1uzqxv04cejkbtsm1shfgkug0kThe EEZZhttps://www.youtube.com/watch?v=ATcrrzJFtBY&lc=z12bdbax0ymdgvqec23ps1pyovjuh3zv2Lazarus The adventurerhttps://www.youtube.com/watch?v=ATcrrzJFtBY&lc=z13pgd0z4uudt55fa22nthxykxilfbrcyForTiorIhttps://www.youtube.com/watch?v=ATcrrzJFtBY&lc=z123hrop2tmlhnx1l23fdznq4q24ft4iw04Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsShane RobinsonDavid NicklasEugene LawsonJoshua DavisQuasarTambe BarsbayMax LevineMayank M.

But even the most elegant and complete formulations of quantum physics – like the Dirac equation or Feynman’s path integral - become impossibly complicated when we try to use them on anything but the most simple systems. But physicists tend to interpret “that’s impossible” as “I dare you to try!” And try they did. First they expressed these impossible equations in approximate but solvable forms. Then they tackled the pesky infinities that kept appearing in these new, approximate equations. Finally, the entire mess was ordered into a system that mere humans could deal using the famous Feynman diagrams.Written and Hosted by Matt O’Dowd Produced by Rusty WardGraphics by Kurt RossAssistant Edit and Sound Design by Mike PetrowMade by Kornhaber Brown (www.kornhaberbrown.com)Comments answer by Matt:Christian Haashttps://www.youtube.com/watch?v=vSFRN-ymfgE&lc=z132vnrhvkq1d3wbi04cdvewopzqjhtidn40kPsy Koshhttps://www.youtube.com/watch?v=vSFRN-ymfgE&lc=z12evvsbtvahjprpx04cclc4nprifxdzwcclohphathttps://www.youtube.com/watch?v=vSFRN-ymfgE&lc=z123gzmhdyezideg504chbuy2rnne1tjx5cSpecial thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsShane RobinsonDavid NicklasEugene LawsonJoshua DavisQuasarTambe BarsbayMax LevineMayank M.

Industrialization was finally improving quality of life for a lot of us, science was making incredible bounds, and our sights were set on the stars. It seemed to many that we were on a trajectory to a space-faring technological utopia. The United Federation of Planets was just around the corner.

In fact we can go even further: according to Feynman’s approach, every conceivable happening that leads from a measured initial state to a measured final state DOES in a sense happen. To calculate the probability of any quantum system evolving from one state into any other state we need to sum over every conceivable intermediate state. This is impossible because there are infinite possible intermediate states.Written and Hosted by Matt O’Dowd Produced by Rusty WardGraphics by Kurt RossAssistant Editing and Sound Design by Mike PetrowMade by Kornhaber Brown (www.kornhaberbrown.com)Comments answer by Matt:Superphilipphttps://www.youtube.com/watch?v=Q8shnjlGwmg&lc=z13act14kwqcvv2nn22muvvztxqnjjryt04Lewinhamhttps://www.youtube.com/watch?v=Q8shnjlGwmg&lc=z12ajhwg3nubdnhaz04cfjfjumr2w5krek40kMyrmidonhttps://www.youtube.com/watch?v=Q8shnjlGwmg&lc=z12xupq5qqiqdbl4h04chd4x0syuxfnb1nk0kSure people love Star Wars.

Everything moves. Planets orbit stars, stars orbit within galaxies, galaxies whirl within the gravitational fields of giant clusters. And of course, the universe is expanding; distant galaxies are thrust apart from each other as the space between them grows. But there’s no preferred direction to any of this motion. Motion due to the expansion of the universe – what we call the Hubble flow – is equal in all directions. The random motion of galaxies – what we call their peculiar motion – should also have no preferred direction. On the largest scales of the universe, there should be no preference for up or down or left or right. At least that’s what we thought. Observations of the cosmic microwave background suggest that the galaxy clusters across the cosmos may be moving, ever so slightly, towards the same point beyond the cosmic horizon. We call this dark flow.Written and Hosted by Matt O’Dowd Produced by Rusty WardGraphics by Kurt RossAssistant Editing and Sound Design by Mike PetrowMade by Kornhaber Brown (www.kornhaberbrown.com)Comments answer by Matt:VacuumDiagramshttps://www.youtube.com/watch?v=fG52mXN-uWI&lc=z12mir3gvw20gxvnq23md5ipdy2xvb33ySamuel Bendahttps://www.youtube.com/watch?v=fG52mXN-uWI&lc=z12vgjnosweevr1kw22oct0jfwugib4pu04JoJoModdinghttps://www.youtube.com/watch?v=fG52mXN-uWI&lc=z134h3i4zuqowhcow04cjfeh3pnmwpmirbkSquid Masterhttps://www.youtube.com/watch?v=fG52mXN-uWI&lc=z123ynkp0m3uhhr4h04cjvxwpkvyvvmo2ekSpecial thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasEugene LawsonQuasarTambe BarsbayMax LevineMayank M.

He picked up the phone and called Richard Feynman. The fateful conversation began, “Feynman, I know why all electrons have the same charge and the same mass." "Why?" asked Wheeler’s former graduate student. "Because, they are all the same electron!" Wheeler went on to describe the One-Electron Universe idea: that there exists only one electron, and that electron traverses time in both directions. It bounces in time, eventually traversing the entire past and future history of the universe in both directions, and interacting with itself countless times on each pass. In this way it fills the universe with the appearance of countless electrons. And when the electron is moving backwards in time it is a positron; the antimatter counterpart of the electron.Written and Hosted by Matt O’Dowd Produced by Rusty WardGraphics by Kurt RossAssistant Editing and Sound Design by Mike PetrowMade by Kornhaber Brown (www.kornhaberbrown.com)Comments answer by Matt:0xFFF1https://www.youtube.com/watch?v=xgdNBQCdhdA&lc=z23sjnwjrwnljxe3macdp435v2eqfl1uknp1kknjllxw03c010c Daniel Grasshttps://www.youtube.com/watch?v=xgdNBQCdhdA&lc=z230gbubioqjyn1vfacdp43azemsjdresxvjbu412tdw03c010c M Paulsonhttps://www.youtube.com/watch?v=xgdNBQCdhdA&lc=z221xpzafrikhxyjf04t1aokgiuxpnkzxeknjelcsx0jbk0h00410 Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasQuasarTambe BarsbayMax LevineMayank M.

There are, of course, some differences. For example, these storms are as big as entire planets. The largest and oldest storm in the solar system is Jupiter’s Great Red Spot, stretching an incredible two to three times the diameter of the planet Earth. Meanwhile the fastest winds ever measured, clocking fifteen hundred miles per hour, once raged in Neptune’s Great Dark Spot. Saturn’s Polar Vortex is a 20,000-mile-wide monster shaped like a hexagon. Even plain-looking Uranus hides USA-sized hurricanes below its methane haze. There are many unsolved mysteries surrounding these epic storms.
