No, relevant physics that prevents FTL is information flow connected with time. This is why people keep referring to the light cone. In other words, something that happens tomorrow is not a causal factor for something that has happened yesterday. The ancients knew that the order of time marched ever forward and that the future does not dictate the past. Even the concept of entropy and disorder was understood at a basic level for quite some time. Probably even before we were humans we understood that an object that has shattered does not spontaneously place itself back together. Or that a log that burns from fire cannot be put back together. Or that the future doesn't influence the past. These are physics concepts so old that they are often forgotten about because they are so obvious.
