Though photons don't have mass, they can force momentum when they hit an object — that's what a solar sail takes advantage of.

Sounds like a bug.

It’s a feature.

Either way, NASA is already exploiting it. I guess, next they’ll find a way to glitch through the very fabric of the universe to teleport to a distant galaxy without moving at all or even using any energy.
