Humans shed a lot of blood, sweat and tears in search of the almighty loophole. From sweet tax dodges to life-extending gene hacks, there's nothing like finding an exploitable weakness in an intensely complicated system.

But is it possible to find a loophole in the universal speed limit? Can we skirt Einstein's theory of special relativity and travel faster than a beam of light?

"As an object approaches the speed of light, all sorts of interesting things happen," says theoretical physicist Richard Obousy. "For example, time dilation occurs and an object’s mass increases. As you reach the speed of light, relativity calculations indicate that an object's mass becomes infinite."
