Simply put: they don't. Though they do travel faster than the speed of light, they can never be slowed down to subluminal speeds, thus they cannot be used to send information faster than the speed of light.
The tricky part would be to harness them to build a solid rocket body in place, without them running away from you.
It would be, perhaps, but from our current understanding of physics, tachyons are impossible.
Theoretically there exist hypothetical particles called tachyons which can travel faster than the speed of light.
Not as far as we know. Theoretically these particles are called tachyons.
Short answer: Yes. Long answer: Yes, it is possible for particles to travel through a medium (not a vacuum!) faster than light can travel through that medium (not a vacuum!), which gives rise to Cherenkov radiation. Tachyons - a type of superluminal particle that is theorized but has never been observed - should be able to travel faster than light, but they would not be able to travel at or below light speed.
You can use both variations. Wiktionary lists "time-travel" as an alternative spelling to "time travel", so it seems "time travel" is the more common version.
Nope, Tachyons might just be the fastest thing in the world...look it up for full description.
Well, tachyons have not been proved real yet. If they were real maybe one day we can possibly travel through time or used their speed of 20 times the speed of light to reach far places the universe and beyond.
Tachyons are imaginary subatomic particles that always travel faster than light.
They are called "tachyons."
Well, tachyons are particles that travel faster than the speed of light. Travel could be referring to how they move across the universe (if they exist) or somehow splitting a object down to the atoms and attaching it to a tachyon particle and sending it through space and time.
Tachyons are hypothetical sub atomic particles that can travel faster than the speed of light.
Tachyons are theoretical particles and cannot be equated to existing massed particles.
Theoretically there exist hypothetical particles called tachyons which can travel faster than the speed of light.
Not only are tachyons possible, but their existence is necessary for many of the most highly accepted current theories of physics.
The question of tachyons is more advanced. The critical point about them is that they do not lead to causality violation (the typical reason cited for FTL being impossible). The question of why most things can't travel faster than c is simpler. First of all, it would lead to causality violation (time travel) - which is a problem. Second of all, massive things have infinite momentum, energy at those speeds, which is also a problem. Both of these results trace directly back to Einstein's postulates of SR, which have held under the closest scrutiny.
Tachyons are hypothetical particles which can travel faster than light. But since they are so fast, none have been detected so far.
Nothing has been found that can.However there is a theoretical prediction of particles that can ONLY travel faster than light (at 0 energy they travel infinitely fast and it takes the addition of kinetic energy to slow them down), they are called "tachyons".
No not ever.
