Question

3. The physical processes that can occur during each stage of the Big Bang depend in part on the geometry of the Universe at that stage.

A. True

B. False

Answer 1

True,

According to Einstein's theory of General Relativity, space itself can be curved by mass. As a result, the density of the universe (how much mass it has spread over its volume) determines its shape, as well as physical processes.. Dense regions pulled in more and more matter through gravity, and the more massive they became, the more matter they could pull in through gravity, forming stars, galaxies and larger structures known as clusters, superclusters, filaments and walls, with "great walls" of thousands of galaxies reaching more than a billion light years in length. Less dense regions did not grow, evolving into area of seemingly empty space called voids.
