So we, and everything we see, result out of quantum fluctuations in what is essentially nothingness near the beginning of time, namely during the inflationary expansion.

Quote in context: 

“This results in the second amazing implication of inflation: That small density fluctuations in empty space, due to the rules of quantum mechanics, will later be responsible for all the structure we observe in the universe today.   

So we, and everything we see, result out of quantum fluctuations in what is essentially nothingness near the beginning of time, namely during the inflationary expansion.    

After all the dust has settled, the generic configuration of the matter and radiation will be that of an essentially flat universe, one in which the average Newtonian gravitational energy of all objects will appear to be zero.”

I offer the modest proposal that our Universe is simply one of those things which happen from time to time.

Quote in context: “If it is true that our Universe has a zero net value for all conserved quantities, then it may simply be a fluctuation of the vacuum, the vacuum of some larger space in which our Universe is imbedded. In answer to the question of why it happened, I offer the modest proposal that our Universe is simply one of those things which happen from time to time.”
