    Causality
In summary, tachyons may or may not violate causality, as there is still much doubt and speculation surrounding their existence. They have not been detected and are thought to be too unstable to exist according to mainstream science. Freeman Dyson has also pointed out an inconsistency in their thermodynamics, specifically the vacuum instability described in the Wikipedia article on Tachyon Condensation.

Because they haven't been detected and are thought to be to unstable to exist according to mainstream science I believe. I don't have anything to go off of other than that article though.

I was once crammed into a New York taxicab with Freeman Dyson and about six other people, and when Dyson was asked about the possible existence of tachyons he replied that there was an inconsistency in their thermodynamics. I believe he was referring to the vacuum instability, as described in the Wikipedia article on Tachyon Condensation.
 

Related to IF tachyons existed,would they violate causality?

What are tachyons?

Tachyons are hypothetical particles that travel faster than the speed of light. They are predicted by some theories in physics, but have not been observed or proven to exist.

How would tachyons violate causality?

Tachyons would violate causality because they travel faster than the speed of light, which is considered to be the maximum speed in our universe. This means that they could potentially travel backwards in time, which goes against the fundamental principle that cause must always precede effect.

Are there any experiments that have demonstrated the existence of tachyons?

No, there have been no experiments that have confirmed the existence of tachyons. Theories that predict tachyons are still purely speculative and have not been supported by empirical evidence.

What are the implications of tachyons existing?

If tachyons were proven to exist, it would have significant implications for our understanding of physics. It would challenge the foundations of our current theories, such as special relativity, and could potentially open up new possibilities for time travel and communication.

Can tachyons ever be observed or detected?

Theoretically, tachyons cannot be observed or detected because they travel faster than the speed of light. This means that they would not interact with normal matter or electromagnetic radiation, making them impossible to detect using current technology.
