The Strangest Idea in Science: Quantum Immortality
29 oktober 2026 · 45 min
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.

The “Crisis in Cosmology” EXPLAINED
29 oktober 2026 · 33 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".

The Doomsday Argument | When Will Civilization End?
29 oktober 2026 · 10 min
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...::More about this Video::► Richard Gott (1993), "Implications of the Copernican principle for our future prospects": http://www.nature.com/nature/journal/v363/n6427/abs/363315a0.html► Fergus Simpson (2016), "Apocalypse Now?

An Idea So Crazy It Might Just Work...
29 oktober 2026 · 38 min
Light sails are a promising method for traveling through space - indeed, Breakthrough Starshot proposed a laser driven version could reach nearby stars. But the exorbitant costs and engineering challenges of such a proposal have stymied its realization. What if there was a way of using the Sun - no lasers required - but keeping our dream of interstellar travel in tact?

Is Time an Illusion? | Prof Sean Carroll
29 oktober 2026 · 6 min
We caught up with Prof Sean Carroll at a recent astronomy conference and got his thoughts about time. Time may seem like a fundamental property of the Universe, but actually there's nothing in quantum theory which requires this to be so. Prof Carroll explains how time being merely an illusion, an emergent property rather than a fundamental one, is actually compatible with our best understanding of nature. This is one of two videos we shot with Sean so look out for the second video later in the year!::More about this Video::► Sean Carroll: "From Eternity to Here" book available on Amazon: https://www.amazon.com/Eternity-Here-Quest-Ultimate-Theory/dp/0452296544► Sean Carroll's blog "Preposterous Universe" at https://www.preposterousuniverse.com/blog/► 229th Meeting of the American Astronomical Society: https://aas.org/meetings/aas229► Background music by Hans Zimmer, Interstellar OST::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!!

Project Starshot | New Research on Relativistic Light Sails
29 oktober 2026 · 12 min
New research paper from the Cool Worlds Lab about one the most exciting missions ever proposed, "Starshot". Starshot plans to send tiny probes to distant planets beyond our Solar System, the first true interstellar spacecraft. To do this within our lifetimes requires a very fast probe, reaching one-fifth the speed of light. That means Einstein's theory of special relativity starts to become important and so in our new paper, explained in the video, we figured out how much of a difference that makes...::More about this Video::► David Kipping (2017), "Relativistic Light Sails": https://arxiv.org/abs/1704.04310► Live stream of the Breakthrough Discuss meeting at Stanford (04/20-04/21): https://www.facebook.com/BreakthroughPrize► Breakthrough Initiatives website: https://breakthroughinitiatives.org► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu► Columbia University Department of Astronomy: http://www.astro.columbia.edu► Background music by Thomas Bergersen "Final Frontier": http://www.thomasbergersen.com ::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!! ヅ

A Machine That Can Predict Exoplanets
29 oktober 2026 · 8 min
Exciting new research from the Cool Worlds Lab has delved into the use of machine learning and artificial neural networks for astronomy. In new work from David Kipping & Chris Lam here at Columbia, we've shown how a machine can predict the presence of extra planets in known planetary systems using just a few pieces of information about the system. Chris Lam gives a neural network 101 and explains our implementation works.::More about this Video::► Kipping & Lam 2016, "Transit Clairvoyance: Enhancing TESS follow-up using artificial neural networks": https://arxiv.org/abs/1611.04904► Tamayo et al.

Why We Might Live in a "Barely Habitable" Universe
29 oktober 2026 · 22 min
Use code coolworlds at https://incogni.com/coolworlds to get an exclusive 60% off an annual Incogni plan.Intelligent design purports that the Universe was made by a creator - God. One of the arguments often invoked to make this case is that the physical constants of the Universe are (apparently) finely tuned to permit life. But cosmologist Denis Sciama presented a thought-provoking analysis of this line of thought and suggested it might be possible to even test intelligent design.

A Cloaking Device for Planets

NSF Graduate Fellow Alex Teachey of the Cool Worlds Lab explains our new paper which devises a method to cloak entire planets from extraterrestrial civilizations!

Why We Haven't Found Any Earth-Like Planets

Twelve years ago, NASA predicted around 50 Earth-like planets would be discovered by the Kepler telescope, planets with the same size, warmth and host star as we do.

Do planets remember how they formed?
29 oktober 2026 · 17 min
After discovering thousands of planetary systems orbiting other stars, we are finally at a point where we can start looking at the patterns we see to hopefully understand how they formed. But hold the phone - because maybe the configurations we see are nothing but purely random. Dynamical evolution tends to disorder initially pristine systems, so do planets even still remember how they formed? Is the ordered nature of the Solar System typical or rare? This week we dive into these questions by discussing a new research paper by Prof Kipping on the topic.::More about this Video::► Kipping (2017), "Do planets remember how they formed?": https://arxiv.org/abs/1709.04987► GitHub repo of the microstate visualizations: https://github.com/CoolWorlds/exoinformatics► Cake number: https://en.wikipedia.org/wiki/Cake_number► Eulerian number: https://en.wikipedia.org/wiki/Eulerian_number► Kepler Orrey by Dan Fabrycky: http://astro.uchicago.edu/~fabrycky/kepler/► Columbia University Department of Astronomy: http://www.astro.columbia.edu► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu► Outro music by 8-bit Universe "Harder Better Faster Stronger [8 Bit Cover Tribute to Daft Punk]": https://8bituniverse.bandcamp.com/track/harder-better-faster-stronger-8-bit-tribute-to-daft-punk::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/CoolWorldsQATabby's Star ► http://bit.ly/TabbysStarScience 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!!
