Einstein's theory of general relativity puts a speed limit on all matter in the universe, creating a barrier preventing acceleration from below to above the speed of light.

However, an independent group of scientists, inventors, and engineers called Applied Physics recently proposed the first model for a physical warp drive, according to a recent study published in the peer-reviewed journal Classical and Quantum Gravity.

While this could make warp drive more than science fiction, it's best to take the new study with a grain of salt — because even if warp drive is now mathematically possible, there's no telling how long it could be until humans could use it to substantially shorten the time of travel between stars — the closest of which would take roughly four years to reach, at light-speed.
