A Universe from Nothing

 

I’m reading the book, “A Universe from Nothing”.  It’s written by a physicist (cosmologist) explaining where all the energy and matter come from, and how they can all seemingly spontaneously arise without actually creating any additional energy or matter in the universe (or multiverse if there are more than one).  On page 202 the author sums up everything he has said so far with:  “…the observation that the universe is flat and that the local Newtonian gravitational energy is essentially zero today is strongly suggestive that our universe arose through a process like that of inflation, a process whereby the energy of empty space (nothing) gets converted into the energy of something, during a time when the universe is driven closer and closer to being essentially exactly flat on all observable scales.”

 

Glad he cleared that up for me; I was starting to lose the thread.
