What is the Big Bang Theory?
The Big Bang Theory stands as the most widely accepted explanation for the origin of the universe. According to this theory, the universe began as an infinitely small, hot, and dense point, which rapidly expanded and continued to stretch over 13.7 billion years.

This initial period of rapid inflation set the stage for the vast and still-growing cosmos we observe today.
Although astronomers cannot directly witness the universe's formation, much of what we know about the Big Bang Theory comes from advanced mathematical models and simulations.
Evidence supporting this theory includes the cosmic microwave background, a faint "echo" of the universe's early expansion that scientists can study in detail. While the Big Bang Theory is widely supported within the scientific community, some researchers propose alternative ideas, such as eternal inflation or a cyclical, oscillating universe.
These theories aim to address questions the Big Bang does not fully resolve, keeping the debate about the universe’s origins alive and dynamic.
