A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed inside a colossal black hole residing in a larger, parent universe. The Big Bang theory, along with Einstein’s general relativity, has successfully explained major cosmological phenomena, including the cosmic microwave background, the universe’s large-scale structure, and its accelerating expansion often linked to dark energy.
“…suggesting that the Big Bang wasn’t the absolute beginning of everything is controversial…”
well I guess its all relative, ayyye?
It depends on what is meant by “absolute” and “beginning”. It’s possible the Big Bang stretches “backward”, which is known as the “no boundary proposal”.
