I have been investigating inflation and the big difference in the theoretically predicted value of the cosmological constant and the actually measured value of it. There would be 120 orders of magnitude in difference for the latter, which became known as 'the largest discrepancy between theory and experiment in all of science'. What we measure today is a very slightly accelerating expansion of the universe, which is ascribed to the negative pressure of dark energy. According to the theoretical prediction, dark energy density would be so great and the expansion of the universe would accelerate so fast that everything would be torn apart almost immediately (known as the Big Rip). So here comes my idea (which is, if I am right, a form of quintessence): what if there was a phenomenon (a field with negative potential?) that counterbalances the theoretically predicted negative pressure of dark energy with positive pressure? The main way in which I can imagine this is that the universe is like a rubber membrane with a certain elasticity (or plasticity). During inflation the membrane would be in the linear range of the stress-strain curve and expand fast. During the post-inflationary phase the expansion would be much slower because the membrane is partially plastic due to strain hardening. But if the universe keeps expanding, there will be a point in the stress-strain curve where the membrane breaks, followed by an immediate Big Rip (much faster than the classical Big Rip scenario). This would be the analogue of a balloon that pops. So is this a scenario that has been proposed in the literature, next to the Big Rip, the Big Crunch, and the Big Freeze scenarios for the future of the universe: the Big Break? And if not, are there good reasons to reject this possibility?
I know that inflation is classically explained by an inflaton field. But that proposal does not seem to solve the infamous discrepancy with respect to dark energy. I also found there is a theory called the Big Pop, but that appears to be about the beginning of the universe, not the end of it.
