 Faster-than-light travel

Faster-than-light (FTL) travel refers to the hypothetical concept of traveling faster than the speed of light, which is approximately 299,792 kilometers per second (186,282 miles per second) in a vacuum. According to our current understanding of physics, particularly Einstein's theory of relativity, as an object approaches the speed of light, its mass increases, and it would require an infinite amount of energy to actually reach or exceed that speed.
