Why does being able to travel faster than light upset cause and effect?

Abacus, as I understand it it is information that cannot be transferred faster than the speed of light. The neutrinos which supposedly travelled at greater than C, do not- I believe- carry information (although I am willing to be corrected on that). Your question poses an interesting point. Does life itself have a finite speed (ie C). P

If something can travel faster than light, then it too must obey rules of cause and effect, and what it does is an "effect" so I can't see that it changes anything.
However if we cannot (yet) detect it then we would not know the cause of it's effects.

The accepted scientific belief is that event A can only cause event B, if there is time for light to travel from A to B. If something could travel faster than light, this rule would be overturned.

If tachyons exist and we can send a beam of them from point A to point B where a detector detects them and starts a process, then we have clear FTL cause and effect.
