The Primeval Atom (theory)

The Primeval Atom theory suggests that the universe began from an extremely hot, dense point—often called a “primordial atom”—which contained all the matter and energy collapsing into a single, infinitely small point. About 13.8 billion years ago, this point began to expand rapidly, leading to the formation of the universe, stars, planets, and galaxies. This idea was an early step towards understanding the Big Bang, emphasizing the universe's origin from a singular, initial condition. It helped shape modern cosmology by proposing that the universe had a definite beginning.
