  The “Crisis in Cosmology” EXPLAINED

  Oct 5, 202632 min

  In the last few years, astronomers have witnessed a growing problem emerge. As measurement precision has increased, the hope was that this problem would abate, but instead it has only exacerbated. Welcome to "The Crisis in Cosmology". But what exactly is the fuss all about, and how much should be believe the sensationalism?Written and presented by Prof David Kipping, edited by Jorge Casas.→ Support our research program: https://www.coolworldslab.com/support→ Get Stash here! https://teespring.com/stores/cool-worlds-storeTHANK-YOU to our supporters D.

  Listening for Alien Civilizations at a Temporal "Waterhole"

  Oct 4, 202611 min

  We're looking forward to the new sci-fi film "Arrival", which explores the barriers to communicating with aliens even face to face. Astronomers really are trying to listen for alien communications, mostly using radio receivers but increasingly by looking for optical laser transmissions too. One of our wild ideas here at the Cool Worlds Lab is that optical SETI could try focussing these efforts to physically-motivated special moments in time to dramatically increase the survey efficiency. Prof Kipping pitches this new concept to all you Cool Worlders!::More about this Video::► Kipping & Teachey (2016), "A Cloaking Device for Transiting Planets": https://arxiv.org/abs/1603.08928► Outro music by Taylor Davis: https://www.youtube.com/watch?v=dl9kI1yQKZk::Playlists For Channel::Latest Cool Worlds Videos ► http://bit.ly/NewCoolWorldsCool Worlds Research ► http://bit.ly/CoolWorldsResearchGuest Videos ► http://bit.ly/CoolWorldsGuestsQ&A Videos ► http://bit.ly/CoolWorldsQAScience of TV/Film ► http://bit.ly/ScienceMovies::Follow us::SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribeCool Worlds Lab http://coolworlds.astro.columbia.eduTwitter https://twitter.com/david_kippingInstagram https://www.instagram.com/cool.worldsTHANKS FOR WATCHING!!

  Why Black Holes Break The Universe

  Oct 4, 202628 min

  Thanks to Storyblocks for sponsoring this video! Download unlimited stock media at one set price with Storyblocks: http://storyblocks.com/CoolWorldsToday we explore a problem that has haunted theoretical physicists for decades and remains a topic of active debate - do black holes destroy information? A key precept in quantum theory is that information should be conserved, yet anything that falls into a black hole is seemingly obliterated. How can we reconcile our theories of gravity with that of the quantum world? And could the answer transform the way we look at the Universe...Written & presented by Prof. David Kipping.
