All records about the previous events become erased, so one cannot remember anything and predict the future.

Fortunately, among all possible parts of the multiverse there should be some exponentially large parts where we may live.A typical closed universe created in the hot Big Bang would collapse in about 10 seconds, in a state with the Planck density.A typical open universe would grow so fast that formation of galaxies would be impossible, and our body would be instantly torn apart.We found that inflation, the stage of an exponentially rapid expansion of the early universe, makes our part of the universe flat and extremely homogeneous.However, simultaneously with explaining why the observable part of the universe is so uniform, we also found that on a very large scale, well beyond the present visibility horizon of about 10 light years, the universe becomes 100% non-uniform due to quantum effects amplified by inflation.
