Astronomy Cast Ep. 6: Ep. 6: More Evidence For the Big Bang

Mon 06: Astronomy Cast Ep. 6: Ep. 6: More Evidence For the Big Bang http://www.astronomycast.com/archive/ From October 16, 2006. Last week's episode started out with a bang… a Big Bang. This week we continue our discussion into the beginning of everything. We present three additional lines of evidence that have led astronomers to the conclusion that our Universe started out as a singularity 13.7 billion years ago, and has been expanding ever since.   Fraser Cain: So Pamela, last week we started out with the big bang and discussed the cosmic microwave background radiation. Now, if people still aren't convinced that the universe began as a singularity 13.7 billion years ago, and has been expanding ever since, fine. We've got more evidence: take your pick. Okay Pamela, continue convincing us!   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
