I just watched the movie 'Back to the Future' and there are hover boards, auto lace Nike air mags, and other futuristic stuff. My question is, can there ever be hover boards? Say the human population survived for eternal time (not possible, but just a scenario.) Could there be a chance of us ever, EVER, in any time ever making a hover board? If we used or found new materials to help us, or went to other planets and found anything to use, can there be a chance of us using hover boards like they do in the movie as skateboards? The creation of one doesn't have to be within the next 40 years or something. It can be within the next 10 billion years. Any chance at all?

Yes, absolutely. We already have vehicles that "hover" in the form of MagLev trains in Asia and Europe. When they're levitating, they're floating a little way above the guide rails. It'd be perfectly possible (although expensive) to build a version that was a skateboard rather than a train. For now, though, you'd be confined to the rail.
Failing that, hovercraft pretty much float on a cushion of air.
