Stars can be accelerated by black holes to speed up to the speed of light Vladimir Arndt/AlamyAfter being speeded up by supermassive black hole orbits, stars that collide may be as bright as the most powerful supernovae. These are some of the most brilliant phenomena in the universe. These cosmic crashes can help us understand more about the environments and most massive black holes in the universe.Stars near the largest black holes are expected to move at the speed of light, despite being shredded by the enormous gravity of their hosts. However, that doesn't mean stars aren't capable of moving at the speed of light.
