I wanted to know if anybody has any plots or graphs that describe the rate of inflation of the universe versus time. I just came to the realization that if the initial inflationary period of the universe is right (as far as the initial rates of expansion, which is immensely big) and if now the universe continues to expand, and moreover its expansion acceleration increases, then there may have been a point in time when the acceleration rate must have decreased to much lower levels then went through a trough, and now it’s increasing again. I ask because the current theory is that the end of the universe will be to expand forever faster and faster until there is basically nothing left, ie. the Big Crunch won’t happen. But why, and how confident do we feel that inflation rates won’t flip to negative acceleration in the future when forces reach a different balance?
