What scientists have learned from the biggest ever collision of black holes

Scientists in the United States have discovered the biggest-known merger of two black holes using gravitational wave detectors.

The scientific findings from the collision, which was recorded in November 2023, were presented at this year’s International Conference on General Relativity and Gravitation in Glasgow, United Kingdom.

What is a black hole?

Black holes are cosmic objects, or regions of space, which comprise a large concentration of matter packed into a relatively tiny space.

The enormous amount of mass packed into a small space creates a gravitational pull so strong that nothing, not even light, can escape it.

As no light is emitted from black holes, rendering them invisible, we do not know what, exactly, is inside them.

Black holes are believed to form when giant stars coll
