There are a few rules in the Universe that seem likely to never be broken. Particles cannot travel faster than the speed of light in a vacuum; the entropy of a closed system can never decrease; energy and momentum must be conserved. But if the rules that the Universe plays by are different than we understand them today, many things that appear to be forbidden today may be possible after all.
In Star Trek: Discovery, a new type of technology takes us even faster than warp drive: the spore drive. Instead of traveling slower-than-light (via impulse engines) or even faster-than-light through space (via warp drive), the spore drive enables an instantaneous "jump" from one location in space to another, disconnected place a great distance away. The idea has been dismissed as a massive science blunder, but the right circumstances could take it from the realm of science fiction to real-life science.
