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!
Examine the big-bang model, the theory behind the evolution of the universe. The universe expanded from a highly compressed state, releasing enormous amounts of energy, which soon coalesced into grains of matter.
