Like a beach chair sagging under a sunbather’s weight, the fabric of spacetime does indeed warp around the mass of the Earth — just as Albert Einstein predicted. And like a swimmer moving through the water, the rotation of the Earth affects the movement of spacetime itself. A gravity probe whose origins date to the era before human spaceflight has finally proved general relativity right, according to NASA.

What: A spacecraft that travels at faster-than-light speeds by distorting, or "warping," the fabric of spacetime. Instead of trying to move through space, the warp drive moves space itself. The ship sits inside a bubble of spacetime bound by a negative energy field that races across the cosmos.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
