Interesting Facts About the Early Universe - What Was The Original Universe?

In its early stages, the universe underwent significant transformations. Gas and dark matter clouds began to coalesce as gravity took hold. During this time, the first stars composed of hydrogen and helium emerged. Surprisingly, enormous black holes with masses of up to 1 billion stellar masses appeared, challenging the standard model of black hole creation, which suggests a slower growth rate over billions of years. Quasars, supermassive black holes at the core of galaxies, were present in the early universe, defying current models. The mystery lies in how these massive black holes formed and gained weight rapidly.

Two main hypotheses address black hole creation. The first suggests the death of a large star leading to the formation of a black hole, but it's unlikely to reach 1 billion solar masses in the given timeframe. The second hypothesis proposes the formation of black holes with up to 100,000 solar masses from short-lived stars, but the required parent stars are exceptionally massive, surpassing observed star sizes.

Simulations show that supermassive black holes could form at the intersections of dense, turbulent gas streams in the early universe, explaining quasar emergence. About 200 quasars may have formed in the first billion years of the universe. This challenges the idea that quasars formed under normal circumstances, suggesting they were a natural result of structure formation in the early cosmos.
