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!!

Lithium demand has been increasing for years thanks to the lithium ion battery. Now, that demand looks set to explode as many nations set new targets for reducing their carbon emissions. Given this, we might well wonder - could we actually run out of the stuff? Join us today as we explore projections for our lithium use and what it all means for the future of our society.Written & presented by Prof David Kipping.

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.

Moore's Law has given us exponential improvements in computer technology for many decades, benefiting everything from astrophysics to iPhones, but is it about to end? Jamie Teherani a Columbia Professor of Electrical Engineering, swung by the Cool Worlds Lab to explain what Moore's Law is all about and predict it's future.::More about this Video::► Jamie Teherani explains how a computer works video: https://youtu.be/8cVsgFN3hSM► Video of a black hole tidal disruption event courtesy of NASA: https://youtu.be/hu6hIhW00Fk► Cool Worlds Lab website: http://coolworlds.astro.columbia.edu► Columbia University Department of Astronomy: http://www.astro.columbia.edu► Outro music by Daft Punk "Harder, Better, Stronger, Faster": http://www.daftpunk.com and http://smarturl.it/DaftPunkiTunes::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!!

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. Join us today as we explore this fascinating concept.Written & presented by David Kipping, edited by Jorge Casas→ Support our research: https://www.coolworldslab.com/support→ Get merch: https://crowdmade.com/collections/cool-worlds→ Check out our podcast: www.youtube.com/@CoolWorldsPodcastTHANK-YOU to D.
