This is one theory. However meanwhile many physicists tend to the opinion that there WAS a cause of the Big Bang, and the Big Bang was not the beginning of time.

One model that is based on String Theory and was developed by Gabriele Veneziano, describes the Big Bang as a collision of 4-dimensional membranes. The intersection of the membranes is our universe, which is just one of many universes embedded in an infinite and eternal 10-dimensional space. While it seems difficult to find information about events before the Big Bang or outside our universe, it's not entirely impossible.
