can there be anything faster than light?

Scientifically is it possible we may discover something faster than light any time in future?

Possible, but very unlikely, for two reasons.

First, the more mass something has, the more energy it takes to move it.  Photons have no mass and move at 300,000 km/s.  To exceed that speed, with our current understanding, would require either negative mass or infinite energy.

Second, the speed of light is really the speed of causality.  Any effect can only be the result of a cause that is within 300,000 km per second since it happened.  If that did not hold, effects would happen before the things that caused them.

Again, maybe one day we will discover that the universal speed limit isn’t what we think it is now (it wasn’t that long ago that we thought nothing could be smaller than atoms), but it will require a fundamental shift in what we know about the universe.
