Back in the Sixties, I read an article in Scientific American about Tachyons. Very interesting theoretical particle. Instead of losing speed when it hits another particle, it gains speed and energy. FTL particle. It was theorized that some Tacyons had had so many collisions and gained so much energy and speed that they were “everywhere, all the time!” I haven’t kept up with the research, but I will read up. I’m more into Spaghettification right now.

Sorry. It’s been 55 years since I read about them;
“the speed of a tachyon increases as its energy decreases. In particular, E approaches zero when v approaches infinity. (For ordinary bradyonic matter, E increases with increasing speed, becoming arbitrarily large as v approaches c, the speed of light). Therefore, just as bradyons are forbidden to break the light-speed barrier, so too are tachyons forbidden from slowing down to below c, because infinite energy is required to reach the barrier from either above or below.”
One of my favorite shows as a kid was ‘Time Tunnel’ . . . goofy, yea . . . but kewl!
The bartender says to the tachyon, what will you have?
A tachyon walks into a bar.
