I didn't realize our theories have changed regarding this. Do you have a good source for an idiot like me?

There was a prior state of the universe before the big bang known as "cosmic inflation". This prior state lasted an unknown length of time.

We also know the now observable universe contained a significant amount of space at the time of the big bang. It was a minimum of 2 meters in diameter, and probably much bigger. Of course, the full universe would have been far bigger.
