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/NewCoolWorlds Cool Worlds Research ► http://bit.ly/CoolWorldsResearch Guest Videos ► http://bit.ly/CoolWorldsGuests Q&A Videos ► http://bit.ly/CoolWorldsQA Science of TV/Film ► http://bit.ly/ScienceMovies ::Follow us:: SUBSCRIBE to the channel http://bit.ly/CoolWorldsSubscribe Cool Worlds Lab http://coolworlds.astro.columbia.edu Twitter https://twitter.com/david_kipping Instagram https://www.instagram.com/cool.worlds THANKS FOR WATCHING!!
