A tachyon is a hypothetical subatomic particle that moves faster than light and is incapable of moving slower than the speed of light.
Tachyons are theoretical particles and cannot be equated to existing massed particles.
The existence of tachyons, hypothetical particles that travel faster than the speed of light, has not been confirmed. Current theories suggest that tachyons would have imaginary mass and could violate causality, leading to paradoxes. As of now, there is no experimental evidence supporting the existence of tachyons.
Tachyons are imaginary subatomic particles that always travel faster than light.
Tachyons are hypothetical particles that travel faster than the speed of light. They have not been observed in nature and their existence is purely theoretical. Some theories suggest that tachyons could have implications for time travel and communication across vast distances, but these ideas remain speculative.
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 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.
Some theories suggest that tachyons could travel faster than the speed of light, but they have not been observed. In current physics, nothing with mass can reach or exceed the speed of light.
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.
hypothetical particles whose velocity exceeds the speed of light also spelled "tachyons"
They are called "tachyons."
Not as far as we know. Theoretically these particles are called tachyons.
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.
