  • The Strangest Idea in Science: Quantum Immortality

    Use code coolworlds at https://incogni.com/coolworlds to get an exclusive 60% off an annual Incogni plan.

    One of the leading interpretations of quantum theory is that every probabilistic event leads to a branching of reality, where all possibilities occur. This "many worlds" interpretation has been growing in prominence, but it implies a bizarre consequence. It might mean that you can never die, and will continue to survive not only life threatening events but even old age. Join us today as we explore the extraordinary idea of quantum immortality.

    Written & presented by Prof. David Kipping. Edited by Jorge Casas.

  • The Doomsday Argument | When Will Civilization End?

    When will our civilization end? Whether it be by our own means or an external threat, there are many plausible scenarios which could extinguish humanity. Remarkably, using the Principle of Mediocrity (that we are just typical observers and not special) it is possible to answer this question statistically with a line of thought called the Doomsday Argument. We get into how this works and what it says about our prospects for survival...

  • Shocking Result from DESI Stuns Cosmology

    Thanks to Storyblocks for sponsoring this video! Download unlimited stock media at one set price with Storyblocks: https://storyblocks.com/CoolWorlds

    The Standard Model of Cosmology has reigned supreme for decades, confirmed over and over again. But chinks in the armour have been developing, such as the Hubble Tension. Now, however, a new result threatens to completely upend our view of the Universe - we no longer even know how it will end.

  • Are UFOs Legitimate Science?

    UFOs, UAPs are dominating the media, but what do astronomers really think is going on? Check out our sponsor by using the code coolworlds to get an exclusive 60% off an annual Incogni plan: https://incogni.com/coolworlds

    Over the last few years, there has been growing public attention and interest in UFOs/UAPs fuelled by whistleblowers, leaked videos and of course the media. But astronomers have been looking for life in the Universe for decades already, using systematic searches and established scientific methodologies. No-one spends more time looking up and thinking about aliens than astronomers, so what do we think about this? How does science more broadly ingest UFO claims? Today, in the spirit of transparency, we explore this complex and evolving topic...

  • The K2-18b Video You've Been Waiting For

    Thanks to Opera for sponsoring this video. Click here to upgrade your browser for FREE! - https://opr.as/Opera-browser-coolworldslab

    So the whole world seems to have become very excited about the claim of a biosignature discovered in the atmosphere of the exoplanet K2-18b. And no sooner did those headlines hit the airwaves, astronomers came out in droves expressing skepticism and concerns. It feels a bit confusing to have two sides so certain of their position, and often the truth is more nuanced than either side will concede. So today, we're going to take a deep dive into K2-18b. You'll get the chance to hear both arguments and make up your own mind.

    Written & presented by Prof. David Kipping. Special thanks to Nikku Madhusudhan and Ryan Macdonald for joining this episode.

  • Can We Engineer The Sun?

    The Sun is dying. A slow death, to be sure, but slowly it creeps towards its end, gradually increasing in luminosity - an effect that will push Earth out of the habitable zone in about a billion years. Can we somehow stop this from happening? Can we save the Earth? Can we save *the Sun*? Join us today as discuss a new research paper from the Cool Worlds Lab at Columbia University, that may help our distant descendants buy themselves billions of years of new life.

    Written and presented by Prof David Kipping and Matt Scoggins (Columbia). Special thanks to melodysheep for giving us permission to use their awesome starlifting animations from "Life Beyond 3" (https://youtu.be/saWNMPL5ygk)
