Hi, Is it possible that there could be another big bang within our universe? What would this mean for our universe? Would it destroy us from the inside like the aliens from the Alien films? If quantum foam is like the canvas of reality and it gave way for the big ban then then why aren't we seeing big bangs all the time or is the big bang really just a one off/rare event? My body is made from quantum foam so what is there to stop my body from giving birth to another universe?
