A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

The theory also suggests that other black holes — all of which rotate, according to NASA — could be wormholes that lead to other universes. The inside of black holes' "event horizons," or ...

The brutal star-destroying tidal disruption event is only the second ever seen in interacting galaxies.

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.

The James Webb Space Telescope has observed a surprising alignment in the spin directions of ancient galaxies, challenging ...

In this framework, our entire observable universe lies inside the interior of a black hole formed in some larger “parent” universe. We are not special, no more than Earth was in the geocentric ...

If decoupling takes place, they showed that the inside of a black hole is a mishmash—rather unlike the smooth stretching of space and time that Schwarzschild’s earlier solution suggested.

About 60 per cent of the galaxies seemed to rotate clockwise. That contradicts the theory that galaxy rotations are random.

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

Black holes may form and grow quietly inside stars due to the accumulation of dark matter, potentially explaining the existence of near- and sub-solar-mass black holes.
