In recent years we have come to understand how the information paradox is
resolved in string theory. The huge entropy of black
holes is realized by an explicit set of horizon sized fuzzball' wavefunctions. The wavefunction of a collapsing shell spreads relatively quickly over this large phase space of states, invalidating the classical black hole geometry the shell would have created. We argue that a related effect may occur in the early Universe. When matter is crushed to high densities we can access a similarly large phase space of gravitational fuzzball’ solutions. While we cannot
estimate specific quantities at this point, a qualitative analysis suggests
that spreading over phase space creates an extra `push’ expanding the Universe
to larger volumes.
