yeah i know its like science fiction but Traveling faster than light and time-travel could be real for tachyons.. was reading about https://www.space.com/tachyons-facts-about-particles how they will probably be the missing link :)))
You are viewing a single comment's thread from:
Tachyons, as many ideas in theoretical physics, are hypothetical. Therefore, for now they do not exist except in our minds. Observing them would, as I said in my previous comment, revolutionise physics.
However, we are not there (at least yet) :)
but there are people working on it :))) "We are beginning an experiment at Berkeley to detect tachyon-like quasiparticles. There are strong scientific reasons to believe that such quasiparticles really exist, because Maxwell's equations, when coupled to inverted atomic media, lead inexorably to tachyon-like solutions.
https://www.scientificamerican.com/article/what-is-known-about-tachy/ well maybe sooner than we think :))) but who's counting lol
Beware, a tachyon-like object is different from a tachyon. It is an object that under specific circumstances behaves as if it would be a tachyon (it consists in an effective description). An elementary particle that is a tachyon is a different story. I had the latter in mind when answering.
To summarise, we compare apples with pears here (I know that from very far, an apple looks like a pear; they are however not the same ;) ).
guess it might be a while before we see something and hopefully well see warp drive in this lifetime ...

What?! I didn't know he passed away. I must admit I don't regularly follow what is going on around ITER (it is a bit far from what I do). Damned.... 72 was not very old...
We will definitely see something (we already saw something). The "something" just needs to be defined.
Cheers!
