You mean, there WAS a universe before the Big Bang?

In “What Was Our Universe Like Before the Big Bang?”, Ryan F. Mandlebaum offers some thoughts at Gizmodo:
To be perfectly clear, we can’t definitively answer this question—but we can speculate wildly, with the help of theoretical physicist Sean Carroll from the California Institute of Technology. Carroll gave a talk last month at the bi-annual meeting of the American Astronomical Society in Grapevine, Texas, where he walked through several pre-Bang possibilities that would result in a universe like ours.
Again, this is a speculation, not theory. “As of yet, these aren’t established as laws of physics we understand or have checked in any way,” said Carroll. As Peter Woit, a theoretical physicist at Columbia University put it to Gizmodo, “A general piece of advice around physicists is when they say ‘we don’t understand what’s going on here,’ they really, really mean it. They’re really in the dark.” More.
