Wormholes don't contradict relativity. In fact they were predicted by relativity (or rather a solution to the singularity problem predicted by relativity).

The scientific name for a wormhole is an Einstein-Rosen Bridge - named after Nathan Rosen and, obviously, Albert Einstein who conceived the idea.

There are other suggestions for "faster than light" travel, but FTL is a bit of a misnomer because the concepts of FTL aren't about having a velocity that's greater than c (the speed of light in a vacuum), it's about warping or cutting through the fabric of space in a way that makes the distances shorter. A wormhole is just one theoretical method of jumping those distances via a shortcut.
