Ancient Universe Heating Detected, Challenging Cosmic ‘Cold Start’ Theories
Astronomers have uncovered evidence that the early universe was heating up rather than cooling down during a critical developmental phase. The findings challenge long-standing theories about how the cosmos transitioned from its dark ages to the illuminated universe we know today.
Cosmic Revelation: Early Universe Was Heating Up
Astronomers have made a groundbreaking discovery about the universe’s early development, according to new research published in The Astrophysical Journal. Using a decade of data from the Murchison Widefield Array telescope in Western Australia, scientists have determined that the universe was heating up during a critical period about 800 million years after the Big Bang, challenging previous theories that suggested a “cold start” to cosmic reionization.
