Graceful exit problem
text:
In physical cosmology, the graceful exit problem refers to an inherent flaw in the initial proposal of the inflationary universe theory proposed by Alan Guth in 1981. In Guth’s model, the period of accelerated expansion makes the universe homogeneous and flat but can never end. The problem with that model, later referred to as "old inflation," is that an energy barrier prevents the universe from escaping inflation, blocking the universe from reheating and forming the stars and galaxies observed
