These Time Paradoxes Prove Reality Is Not What We Think

Hey guys! We’re now live on Spotify🎧 Listen here: https://open.spotify.com/show/1c2uppn... In 1929, the best measurement of the expanding universe made it younger than the rocks of the Earth. That is only paradox number nine. Ahead lie Stephen Hawking's party for time travelers, a 2011 experiment that seemed to clock neutrinos outrunning light, and a billiard ball that tries to stop itself from ever existing. So what waits in the top three? Ten time paradoxes in a slow three-hour walk, made to be heard at any pace, even as you drift off to sleep. Settle in and let this slow walk through the paradoxes of time keep you company tonight. Subscribe to The Cosmographer if you like the long way through the universe's biggest questions.
