While it is true that our understanding of physics has evolved over time and some components of Einstein's theories have been revised or refined, it is important to note that the core principles of his theories, such as the theory of relativity, have withstood extensive experimental testing and verification. These theories have consistently provided accurate predictions and explanations for a wide range of physical phenomena.
there is no scientific evidence or theoretical framework that supports the possibility of faster-than-light travel within our current understanding of physics. The theory of relativity, particularly the theory of special relativity, firmly establishes the speed of light in a vacuum as an absolute limit in the universe.
Einstein's theories have been tested and confirmed through numerous experiments and observations, and they form the foundation of modern physics. While there are still outstanding questions and areas of exploration within physics, such as the unification of general relativity and quantum mechanics, these do not provide a basis for suggesting that faster-than-light travel is possible.
It's important to approach scientific ideas and possibilities with critical thinking and rely on empirical evidence and rigorous experimentation. Until compelling evidence emerges or significant revisions are made to our current understanding of physics, it is reasonable to consider faster-than-light travel as highly unlikely, if not impossible, based on our current scientific knowledge.
