What are tachyons?
Tachyons are hypothetical faster-than-light particles. Physicists asked themselves, “What would be the characteristics of matter if it did move faster than light?” — a kind of thought experiment. One odd thing is that to slow down a tachyon, you would have to put energy into it. In fact, it would take infinite energy to get it to slow down to the speed of light – that is if it has any mass. That brings me to the next interesting point – one way to view the momentum of tachyons is to consider that they have imaginary mass. So far any attempt to observe a tachyon has come up dry, and most physicists have abandoned the idea that tachyons might be real. The only tempting recent clue was a recent measure of the rest mass of a neutrino. They got an imaginary number. This result was NOT attributed to tachyon properties, in fact, the experimental report attributed the results to possible errors in some of the supporting information used to make the calculations.
