WebDirac-tachyon states that designates the naming of particle vs anti-particle; and there has been some uncertainly about whether this is a Lorentz invariant rule. Here is a short table of simple calculations of the scalar and the pseudoscalar forms for an ordinary Dirac wavefunction o and for a tachyon Dirac wavefunction t, both sensibly normalized. WebThese tachyons do not violate causality, because there is no way of using them for sending information with superluminal speed. However, they make the vacuum unstable (since there is no lowest-energy state anymore). It is the actual reason of theories with tachyons being considered unphysical. Share. Cite.

The reinterpretation principle asserts that a tachyon sent back in time can always be reinterpreted as a tachyon traveling forward in time, because observers cannot distinguish between the emission and absorption of tachyons.

A tachyonic antitelephone is a hypothetical device in theoretical physics that could be used to send signals into one's own past. Albert Einstein in 1907 presented a thought experiment of how faster-than-light signals can lead to a paradox of causality, which was described by Einstein and Arnold … See more Tolman used the following variation of Einstein's thought experiment: Imagine a distance with endpoints $${\displaystyle A}$$ and $${\displaystyle B}$$. Let a signal be sent from A propagating with velocity $${\displaystyle a}$$ towards … See more Benford et al. wrote about such paradoxes in general, offering a scenario in which two parties are able to send a message two hours into the past: The paradoxes of backward-in-time communication are well known. Suppose A and B enter into … See more A more common variation of this thought experiment is to send back the signal to the sender (a similar one was given by David Bohm See more As an example, Alice and Bob are aboard spaceships moving inertially with a relative speed of 0.8c.
