Question
Inflation during the Big Bang refers to:
a. the rapid expansion that occurred when gravity separated from the other forces and briefly became repulsive.
b. a process that can explain the current observation of the acceleration of the expansion.
c. the general property of the Big Bang that refers to the expansion of the universe with time.
d. the fact that at the earliest times before the inflation occurred we were in causal contact with a portion of the universe that extends far beyond the present known universe.
e. the fact that the knowable universe is bigger than the known universe.
(There can be multiple correct answers or no correct answers)
Explanation / Answer
Cosmic inflation is the idea that the very early universe went through a period of accelerated, exponential expansion during the first 10-35 of a second before settling down to the more sedate rate of expansion we are still experiencing, so that all of the observable universe originated in a small (indeed, microscopic) causally-connected region.
Hence in above question,
Inflation during the Big Bang refers to-
a. the rapid expansion that occurred when gravity separated from the other forces and briefly became repulsive.
Option a is true.
