Explanation:
Detailed explanation-1: -While an explosion of a man-made bomb expands through air, the Big Bang did not expand through anything. That’s because there was no space to expand through at the beginning of time. Rather, physicists believe the Big Bang created and stretched space itself, expanding the universe.
Detailed explanation-2: -In 2001, Wendy Freedman determined space to expand at 72 kilometers per second per megaparsec-roughly 3.3 million light years-meaning that for every 3.3 million light years further away from the earth you are, the matter where you are, is moving away from earth 72 kilometers a second faster.
