Thanks to the wonders of physics, astronomers can map a timeline of the universe’s history. Today, Phil’s going to give you an overview of those first few minutes (yes, MINUTES) of the universe’s life. It started with the Big Bang when the Universe was incredibly dense and hot. It expanded and cooled, going through multiple stages where different kinds of matter could form. It underwent a phenomenally rapid expansion called inflation, which smoothed out much of the lumpiness in the matter. Normal matter formed atoms between 3 and 20 minutes after the bang, and the lumps left over from inflation formed the galaxies and larger structures we see today.Check out the Crash Course Astronomy solar system poster here: http://store.dftba.com/products/crashcourse-astronomy-posterIf you want to learn more about the creation and death of the universe, watch Crash Course Big History here: https://youtube.com/playlist?list=PL8dPuuaLjXtMczXZUmjb3mZSU1Roxnrey--Chapters:Introduction: The History of the Universe 00:00Giant Particle Colliders 1:22Phase Changes 1:58After the Big Bang: The First Minutes 4:29Recombination 6:15Inflation 8:36Unanswered Questions in Astronomy 10:31Review 11:22--PBS Digital Studios: http://youtube.com/pbsdigitalstudiosFollow Phil on Twitter: https://twitter.com/badastronomerWant to find Crash Course elsewhere on the internet?Facebook - http://www.facebook.com/YouTubeCrashCourseTwitter - http://www.twitter.com/TheCrashCourseTumblr - http://thecrashcourse.tumblr.com Support CrashCourse on Patreon: http://www.patreon.com/crashcourse--PHOTOS/VIDEOSProton Collision Event with Boosters and LHC https://www.youtube.com/watch?v=NhXMXiXOWAA [credit: ATLAS]Melting Snowball video courtesy of Phil PlaitBig Bang to Hubble http://www.spacetelescope.org/videos/hst15_big_bang_to_hubble/ [credit: ESA/Hubble (M.
