Question:
What occurred before the big bang?



Replies:
We do not know. There is nothing that we can now see that we have identified as showing us something from before the big bang. The big bang followed a time when matter was so dense that we have no good theory about what it was like. We have no idea about what was happening before the big bang itself. The one thing we can measure is the background infrared radiation (which was recently seen to be slightly non-uniform) and this radiation only dates back toward the big bang to a time when matter became low enough density for light to escape it. This was a long time after the big bang itself. There is a good book called the First Three Minutes, by Weinberg that describes some of this. I do not know if it is appropriate for your level and I do not know if it is easily available.
