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: -The general view of physicists is that time started at a specific point about 13.8 billion years ago with the Big Bang, when the entire universe suddenly expanded out of an infinitely hot, infinitely dense singularity, a point where the laws of physics as we understand them simply break down.
Detailed explanation-3: -The universal origin story known as the Big Bang postulates that, 13.7 billion years ago, our universe emerged from a singularity-a point of infinite density and gravity-and that before this event, space and time did not exist (which means the Big Bang took place at no place and no time).
