Thanks for your help here! One more question, how did inflation add energy to the universe? What mechanism did this occur by? In other words, where did that energy come from? Was it due to the quantum fluctuation (or that scalar field rolling down a potential energy hill) to a lower, more stable...

Well it had to be pretty dense and small if: Also, from Wiki,

Will the negative pressure of dark energy which is driving current and future expansion also "flatten" the universe? Why?

I posted these on Reddit but some questions weren't answered so I was wondering if people here could help: First Part I was informed that the universe did actually exponentially gain energy during inflation and perhaps other periods of its development. So how does this affect the entropy and...
