Cosmic inflation refers to a brief early period of hyper-rapid expansion of space-time

Explanation:

Cosmic inflation -

It is the theory of the exponential expansion of the space during the early universe phase.

After the inflationary period, the universe continuously expands, but to a reduced rate.
