Tachyons are any theoretical particles that have an imaginary mass. Because all tachyons have an imaginary mass, the velocity of all tachyons must exceed the speed of light (contrasted with Bradyons like electrons, quarks, and composite particles which must always move slower than light). Most modern theories suggest that even if such particles exist, they would likely be short lived due to effects such as tachyon condensation.
Despite theoretical arguments against the existence of faster-than-light particles,
experiments have been conducted to search for them. No compelling evidence for
their existence has been found.
If they are real, they go 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.
No not ever.
Tachyons are theoretical faster than light particles.
All objects with a non-zero real mass are subject to the gravitational force. It's not quite clear (at least to me) what the situation is with respect to objects with imaginary mass (tachyons).
NO! According to relativity theory it is not possible for anything with mass to travel faster than light.However there are particles that have been hypothesized(but never detected, so they may not exist) called tachyons (meaning "the fast ones") that always travel faster than the speed of light.
Tachyons are theoretical particles and cannot be equated to existing massed particles.
Not only are tachyons possible, but their existence is necessary for many of the most highly accepted current theories of physics.
Tachyons are imaginary subatomic particles that always travel faster than light.
No not ever.
Depends what you mean by "fringe." Some PhD's in major institutions are doing research into tachyons. But it is not considered an area that a LOT of research effort is being or should be done.
Tachyons are theoretical faster than light particles.
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.
They are called "tachyons."
hypothetical particles whose velocity exceeds the speed of light also spelled "tachyons"
Not as far as we know. Theoretically these particles are called tachyons.
Tachyons are hypothetical sub atomic particles that can travel faster than the speed of light.
It seems unlikely, considering that there are good reasons to consider that the speed of light is an absolute speed limit in our Universe.
