Share, One scientist has made a theoretical model showing that a warp drive can propel a spaceship in excess of light speed. It works by expanding space-time, thus it would not violate the speed limit for light.
But, so far, none knows how to build such a machine. Without such a drive, it would be almost impossible for humans to get to the nearest habitable exoplanet. If you're interested in a longer discussion of this idea, you should watch Leonard Susskind's lecture on Cosmology. It's a fascinating subject.
