While there have been advances and refinements in our understanding of physics since the time of Einstein, it's important to note that his theories, particularly the theory of special relativity, have been incredibly successful in describing and predicting a wide range of phenomena. They have been extensively tested and verified by numerous experiments.
there is no experimental evidence or theoretical framework that supports the possibility of faster-than-light travel for matter with mass. According to the theory of special relativity, the speed of light in a vacuum is an absolute speed limit, and matter with mass cannot reach or exceed this speed. This principle is deeply ingrained in our current understanding of physics.
It is worth mentioning that there are speculative theories and concepts, such as wormholes or exotic matter, that have been proposed as potential avenues for faster-than-light travel. However, these ideas remain purely speculative and are highly speculative areas of research. They often involve significant theoretical and technological challenges and have not been experimentally confirmed.
It's important to approach such ideas with caution and rely on scientific evidence and consensus. Our current understanding, based on decades of research and experimentation, strongly suggests that faster-than-light travel is not possible for matter with mass.
