what is the nature of tachyons ?
Answers
Most scientists do not believe that tachyons exist. Einstein's theory of special relativity states that nothing can accelerate faster than the speed of light, while tachyons are theorized to be constantly traveling faster than the speed of light. If a tachyon did exist, it would have an imaginary number as its mass.
Answer:
A tachyonic particle is a hypothetical particle that always travels faster than light.
Explanation: Most physicists believe that faster-than-light particles cannot exist because they are not consistent with the known laws of physics.If such particles did exist, they could be used to build a tachyonic antitelephone and send signals faster than light, which (according to special relativity) would lead to violations of causality. No experimental evidence for the existence of such particles has been found.
