Wired: People call them hoverboards, but they clearly don’t hover. If you haven’t seen one, it’s basically a Segway without the handle. So sure, riding one makes it look like you’re gliding over the surface, sort of like hovering.

Riding a hoverboard requires some physics. In this case, Einstein’s Theory of General Relativity. We can use it to explain an accelerating hoverboard.
