A warp drive that doesn’t break the laws of physics is possible

By Leah Crane

Warp drives may be on the road to reality. Previous ideas about how to make these hypothetical devices have required exotic forms of matter and energy that may not exist, but a new idea for a warp drive that doesn’t break the laws of physics may be theoretically possible. However, it may not be practical in the foreseeable future because it requires ultra dense materials.

Contrary to what its name may suggest, a warp drive isn’t really an engine. Rather, it is a bubble of space-time protected by …
