"Faster Than Light" (FTL) refers to the concept of traveling faster than the speed of light, which is approximately 299,792 kilometers per second in a vacuum. According to the theory of relativity proposed by Albert Einstein, nothing with mass can reach or exceed this speed, as it would require infinite energy. FTL travel remains a popular topic in science fiction, often depicted through various fictional technologies. In theoretical physics, some concepts, like wormholes and warp drives, suggest possible methods for FTL travel, but these ideas remain speculative and unproven. Current scientific understanding indicates that FTL travel would violate the known laws of physics, making it an intriguing yet elusive possibility.
