Are tachyons real?
Answer 1:

So far, the existence of tachyons, which are particles that move faster than the speed of light, is still just a theory. There have not been any confirmed observations of such particles, although physicists are devising experiments to look for them.

The existence of tachyons is not consistent with the current models and theories of the universe (particularly Einstein's theory of special relativity), however, historically, theories about the universal laws of physics have experienced revisions as we discover and explain new phenomena.

Whether or not tachyons are real, the idea is fascinating, and it's important to propose new ideas in Physics and examine under what mathematical and physical conditions they could be true. This is where physicists get to exercise their creative minds!


Answer 2:

They've never been detected, and none of the mainstream theories say that they should exist. As such, the answer is probably not, but it's hard to know for sure.
