First of all, the Big Bang wasn’t very big. Second of all, there was no bang. Third, Big Bang Theory doesn’t tell you what banged, when it banged, how it banged. It just said it did bang. So the Big Bang theory in some sense is a total misnomer.
We need a theory that goes before the Big Bang, and that’s String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Will that umbilical cord is called a wormhole.

Think of two bubbles with a tube connecting these two bubbles and as one bubble fissions from the other bubble, there is this umbilical cord connecting these two universes. So some people believe that maybe, just maybe, we have detected evidence of that umbilical cord. So we’re looking at the data very carefully now, by next year we should be able to resolve the question, have we picked up a signal from a parallel universe?
