A hypothetical particle that always moves faster than light is called what?
bradyon
luxon
lepton
tachyon
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 send signals faster than light, which would lead to violations of causality. Despite those arguments, experiments have been conducted to search for them, but no compelling evidence has been found.
