The model of the universe that involves an enormous increase of scale during a very short time in the early universe is called the inflationary universe model. Here's why:
1. Inflationary Universe Model:
- This model proposes that the universe underwent a rapid and exponential expansion just fractions of a second after the Big Bang.
- The rapid expansion is believed to have occurred due to a hypothetical scalar field called the inflaton.
- This theory helps to explain the uniformity and flatness of the universe on large scales, as well as the observed cosmic microwave background radiation.
In summary, the correct answer to the question is the inflationary universe model, which describes the rapid expansion of the universe in its early stages.
