muawiyah, tachyons don’t exist. They are from the show Star Trek. In the real world, they are merely a hypothetical particle and have never been detected in experiments.

Oh yes they do. I have one.

BTW, Star Trek was released in 1966. Earlier in that decade a number of scientists had begun discussing tachyons as theoretical particles. Later on they began showing up as possible constructs inside newer theories that attempt to combine quantum physics and relativity.

This is all publicly available information so you should already be on top of it.

Regarding further "futuristic" entertainment shows string theory didn't arrive, even in part, until the end of the 1960s (the Bosonic String Theory).

So, here's your continuum ~ "tachyons, Star Trek, string theory) ~ in that order. Although you might argue that Star Trek somehow influenced string theory, you would be wrong to argue that Star Trek influenced tachyon theory ~ unless you want to jump into the time travel business.
