Why Tachyons Aren't Allowed in Physics Theory

In summary, tachyons, which are particles with a speed faster than light, are not allowed to exist in physical theories due to the difficulty in detecting them. While their existence is still an open question, some argue that they do not exist in our universe because of our inability to detect them.

Why NO tachyons ??

my question is why are Tachyons NOT allowed to exists in physical theories ??

they would be particles with speed faster than light.. is this the main reason ?? could be they detected someday in accelerators, how does Standard model of particles interact with Tachyons.

Who said there were no tachyons? As far as I know the existence of tachyons is an open question. The difficulty appears to be that if there were tachyons, we would have no way of detecting them. And some people assert that, for that reason, as far as our "universe" is concerned, they don't exist.

Why?
 

1. Why are tachyons not allowed in physics theory?

Tachyons, hypothetical particles that travel faster than the speed of light, are not allowed in physics theory because they violate the fundamental principles of relativity. According to Einstein's theory of relativity, the speed of light is the maximum speed at which any form of matter or information can travel. Tachyons, traveling faster than the speed of light, would break this fundamental rule.

2. What evidence is there that tachyons do not exist?

There is currently no empirical evidence that tachyons exist. In fact, the existence of tachyons would contradict many well-established theories in physics, such as the theory of relativity and quantum mechanics. Additionally, no experiments have ever detected the presence of tachyons, further casting doubt on their existence.

3. Could tachyons be used for time travel?

No, tachyons cannot be used for time travel. While tachyons are thought to travel faster than the speed of light, they would still be subject to the laws of causality. This means that events cannot occur before their causes, ruling out the possibility of using tachyons for time travel.

4. Are there any theories that allow for the existence of tachyons?

There have been some theories proposed that allow for the existence of tachyons, such as the tachyon field theory and the tachyon condensation theory. However, these theories are highly speculative and have not been supported by experimental evidence.

5. Could tachyons be responsible for dark matter or dark energy?

No, tachyons are not a viable explanation for dark matter or dark energy. Dark matter and dark energy are currently explained by other theories, such as the presence of unseen matter or the effects of the expansion of the universe. Tachyons, with their hypothetical properties and lack of evidence, cannot explain these phenomena.
