lol, that question of light is actually kind of interesting to ponder.
Now I'm thinking about that episode of Futurama...
Professor: These are the dark matter engines I invented. They allow my starship to travel between galaxies in mere hours.
Cubert: That's impossible. You can't go faster than the speed of light.
Professor: Of course not.
That's why scientists increased the speed of light in 2208.
Cubert: Also impossible
Professor: And what makes my engines truly remarkable is the afterburner, which delivers 200% fuel efficiency.
Cubert: That's especially impossible.
Professor: Not at all, it's very simple.
Cubert: Then explain it.
Professor: Now THAT's impossible.
