Black holes are stronger than the speed of light
Measuring the speed of anything is done using light; this is because examining how long it would take light to travel between stars and galaxies gives scientists a better understanding. In other words, it’s pretty swift. For an extensive amount of time, researchers have looked into whether or not something can surpass the speed of light.
This recent discovery by astronomers, conducted using NASA’s Chandra X-ray Observatory, suggests that a supermassive black hole in Messier 87 is spinning and attracting matter at speeds exceeding 99% the speed of light. Thus, we can infer that black holes are stronger than the speed of light itself.
