Faster-than-light (FTL) refers to the hypothetical ability to travel or transmit information faster than the speed of light in a vacuum, which is approximately 299,792 kilometers per second (about 186,282 miles per second). In the realm of physics, particularly according to Einstein's theory of relativity, nothing with mass can travel at or exceed the speed of light.
