What is the matter era?

Quick Reference. In the Big Bang theory, the era that started when the gravitational effect of matter began to dominate the effect of radiation pressure. ...

What happens during the epoch of inflation?

In physical cosmology the inflationary epoch was the period in the evolution of the early universe when, according to inflation theory, the universe underwent an extremely rapid exponential expansion.

How big was the universe at the end of inflation?

In the inflationary model, between 10-35 and 10-33 seconds, the "universe" doubles in size every 10-35 sec. By the end of inflation then, space-time is 1050 times bigger than it was before inflation. Regions of "this universe" "supercool" and "nucleate" away from the rest.

How fast was inflation of the universe?

According to the theory of inflation, the early Universe expanded exponentially fast for a fraction of a second after the Big Bang. Cosmologists introduced this idea in 1981 to solve several important problems in cosmology. One of these problems is the horizon problem.
