The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

However, although photons of light existed since the first second after the Big Bang, they could not yet shine across the ...

A controversial theory suggests the observable universe is the result of matter rebounding after the collapse of a black hole ...

Did The universe really begin with a bang, a bounce? The theory that the universe is both possibly having endured a sudden ...

The Big Bang may mark an end—not the start—of a previous universe's aeon. Penrose's theory sees the universe as an eternal ...

Crucially, this bounce occurs entirely within the framework of general relativity, which applies on large scales such as ...

The earliest and most distant supermassive black hole discovered thus far by JWST is CEERS 1019, which existed just 570 ...

The earliest light in the universe has been traveling across space since just after the Big Bang. Known as the cosmic ...

The Big Bang theory is wrong and the universe is sitting inside a black hole, scientists have suggested. Since the 1930s – when Belgian theoretical physicist Georges Lemaitre proposed the universe ...

The universe may not have begun with the Big Bang as is generally thought but from the collapse of a massive black hole, a new theory suggests. At such a critical moment in US history, we need ...

A UK study challenges the Big Bang theory, proposing that the universe exists inside a black hole. The new model suggests a gravitational collapse created the universe.
