Speed of light and modern physics

[commander_24]

What will happen if something traveling faster than light is found?What effect will it have on modern physics?

If you mean in another matter medium , the object will radiate a cherenkov radiation, if in vacuum Its not possible and not even possible, and It'll never happen, you must have an infinity energy to do that , and since infinity is undefine ( there is no specific last number), you can't ever and never ,even in your physical dreams travel faster than light, then you'll conflict the mathematical logic, and hence the all of mathematics, and hence the all of physics, even quantum physics!

What effect will it have on modern physics?

You can get a pretty good idea about the early stages from studying the community’s reaction to the OPERA experiment’s report of FTL neutrinos. There would be a large number of initial papers on the possible cause quite soon after the discovery. Generally it would also be met with a significant amount of healthy scepticism. If, unlike the FTL neutrinos, the result would hold up to scrutiny, we would eventually need to start taking it seriously and work on finding a theory that can supersede relativity.

It'll never happen, you must have an infinity energy to do that

Accordingto SR, but this is not what the OP was asking. The OP asked about the possible reprecussions.
