The ‘warp drive’ has been a staple of science fiction ever since Einstein put the kibosh on ‘faster-than-light’ travel with his theory of relativity.
But it might not only be science fiction anymore. NASA may have already developed a type of warp travel, though there is still a lot of research that needs to be done.
It’s amazing that this is even a possibility. And it all came about through the introduction of something else no one believed possible: an ion propulsion engine.
This imagination-stimulating information is from an IFLScience article: Has NASA really created a warp drive?
NASA is more cautious: Is warp drive real?
More information on NASA’s view on faster-than-light (or warp) travel: Status of “Warp Drive”
But they are optimistic about ion propulsion engines: NEXT provides lasting propulsion and high speeds for deep space missions
All in all, some lovely fodder for the science fiction imagination.
