According to Einstein's theory of relativity, the speed of light is constant. That's just all good and dandy. The interesting part is the side effect that if you approach this speed of light, and then hit the throttle even more, you won't be going much faster, but time will actually start to slow down. This is the effect called Time Dilation.

The theory is that when you do something at near-light speed, time around you will slow to a near stop. That means that you - in the eyes of a spectator - actually did it so fast that you almost didn't do it. It was close to instantaneous. And - this is the good part - you yourself experience the time at normal rate. All because time is relative.

The usual scientific focus on this phenomenon revolves only around the impact it has on travelling at light speed. But there are so many other activities that are far more compelling to do in such a "time-pocket". Just realize that you get to spend all the time you want without actually spending any time at all. 

Just think how nice it would be if you could take a nap at work for a few hours, but to your coworkers no time has passed, so no one will ever know. You will just need to sleep really, really fast - at light-speed. Or consider if you want to take a long hot bath after a long day at work before going to visit your grandma. But you're having very little time because she goes to bed so darn early. Now if you bathe at a lightning-fast speed you can actually bathe for as long as you want. Grandma is frozen in time from your point of view in the bathroom. The same goes for watching TV. At light-speed you get all the time you want, and no one can complain about wasted time that should've rather been spent on fixing the lawnmower.

So I really hope relativity researchers will focus more broadly in the field of light-speed issues than mere travel. There are so many daily tasks to look into. Einstein has really only scratched the surface.
