🪐 Light travels faster than anything else in the universe—at a speed of 299,792 kilometers per second in a vacuum—so a radio signal sent from Earth would reach the Moon in just over a second. The jets ejected by the supermassive black hole in galaxy Centaurus A shoot out at speeds close to this ultimate limit, but nothing with mass can ever actually reach the full speed of light. ✨ #speedoflight⚡#spacephysics⚡#centaurusa⚡#nasa⚡#galaxy⚡#stars⚡#astronomy⚡#universe⚡#cosmos⚡#space 👉subscribe Universe Mysteries 👉more Channels
