Einstein’s general theory of relativity is a tool kit for solving problems involving gravity that connects mass and energy with deformations in spacetime. In turn, those spacetime deformations ...

A team of physicists has discovered that it’s possible to build a real, actual, physical warp drive and not break any known rules of physics. One caveat: the vessel doing the warping can’t exceed the ...

How much do we really know about what else is out there in the universe? Let's take an outlandish example. If there were aliens flying around our galaxy with the sort of warp drive technology we often ...
