Jun 13, 2024 · The Short Answer: 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!
Mar 4, 2024 · Big Bang Theory is about the origin of the Universe. It suggests that about 1370 crore (13.7 billion) years ago, all matter and energy in the universe was concentrated in an area smaller than an atom. At this instant, matter, energy, space, and time were not existent. Then suddenly with a bang, the Universe began to expand at an incredible rate ...

Hubble’s discovery was the first observational support for Georges Lemaître’s Big Bang theory of the universe, proposed in 1927. Lemaître proposed that the universe expanded explosively from an extremely dense and hot state, and continues to expand today. Subsequent calculations have dated this Big Bang to approximately 13.7 billion years ...
