Back in January, I shot a couple a videos with Sean Carroll at the 229th American Astronomical Meeting. Well, at last here is the second video from that day where I asked Sean - "What was before the Big Bang?". This is probably one of the most commonly asked questions I get as an astronomer, so check out what a true expert on the subject thinks about this question in just under 3 minutes!
