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

A star met a violent end in a galaxy far, far away — about 600 million light-years from Earth. It wandered too close to a black hole and was ripped apart in a bright burst of light.

NASA has discovered a rogue supermassive black hole, devouring a star 600 million light-years away. The cosmic predator - equal to a million suns in mass - was spotted outside the core of its ...
