Was Gravity turned off during inflation?

    Do the current models of inflation contain an implicit understanding that gravity is some how turned off during the inflationary expansion? Does the scientific community believe that gravity is a temperature dependent phenomina?

    No. Why do you think this might be true?

    Actually, far from having been turned off, current theories of inflation say that gravity was actually a repulsive force during inflation, and is what drove inflation. Here is an excellent web site by Alan Guth, one of the inventors of inflation theory, that explains at a high level what the theory says.

    Thanks. This helps my understanding of why the early universe was not a black hole.

    Thanks Phyzguy. I have had questions about inflation and you answered them. Now hyperinflation makes sense.
    thanks again, BT
