Can time travel be possible?

Time travel is a popular concept in science fiction, but scientifically, it's still theoretical. According to Einstein’s theory of relativity, time can slow down near light speed or strong gravity, suggesting forward time travel is possible under extreme conditions. Backward time travel poses paradoxes and lacks evidence. Some theories propose wormholes as time portals, but they’re unproven. While intriguing, time travel remains beyond current human capability.
