Detailed explanation-1: -According to the Big Bang theory, which proposes that the universe is roughly 13.7 billion years old, all matter and energy were at one time compressed into a single microscopic point. This point then exploded outward in all directions in a rapid expansion.
Detailed explanation-2: -In short, the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time, roughly 13.8 billion years ago. At this time, all matter was compacted into a very small ball with infinite density and intense heat called a Singularity.
Detailed explanation-3: -The universe will eventually stop expanding and start collapsing in on itself, the so-called “Big Crunch.” If the density of the universe is less than this critical density, then the geometry of space is “open (opens in new tab)” and “negatively curved” like the surface of a saddle.
Detailed explanation-4: -The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now-and it is still stretching!
