VACUUM GENESIS HYPOTHESIS

Vacuum genesis suggests that the universe began as a single particle arising from an absolute vacuum. Curious as it may seem, this idea violates none of the known laws of physics. We have seen how virtual particles come into existence all the time from a vacuum and then fall back into non-existence. There appears to be no upper limit on the size and longevity of particles that can be created in this way. It's just possible that there might have been absolutely nothing out of which came a particle so potent that it could inflate into the entire universe. It's not very likely, but then it only had to happen once.
