2025 GMAT: Turn RC Mistakes into Points

Most attempts by physicists to send particles faster than light have been unsuccessful. This is because the speed of light, approximately 299,792 kilometers per second, is considered the universal speed limit according to Einstein’s theory of special relativity. As an object with mass approaches the speed of light, its relativistic mass increases infinitely, requiring an infinite amount of energy to accelerate it further. This fundamental principle is a cornerstone of modern physics and has been repeatedly validated through experiments.

However, the concept of faster-than-light (FTL) travel continues to be a fascinating area of theoretical exploration, particularly in science fiction. While real-world physics currently presents significant barriers, some theoretical loopholes and hypothetical concepts, such as warp drives or wormholes, are occasionally discussed. These ideas, while speculative, stem from interpretations of general relativity and quantum mechanics that push the boundaries of our understanding. It’s important to distinguish between established physics and these more speculative theories, as the former dictates what is currently possible, while the latter explores the fringes of what might one day be conceivable, though not necessarily achievable.
