| Inflationary Universe |
A class of Big Bang models of the universe that include a finite period of accelerated expansion in their early histories. Such an event would have released enormous energy, stored until then in the vacuum of spacetime. The horizon of the universe expanded, temporarily, much faster than the speed of light. This theory is able to account satisfactorily for the present vast extent of the universe and its uniformity.
