 Calculated through the fuel they use, you go the speed of light. It takes four years, whatever year. Now, we're both going the same speed. Now, if I go in a second gear, if you will, and I go, say, five miles faster than the speed of light, if I look back from my rocket that I'm in, what do you think you see in between me, the rocket, going faster than the speed of light, and the speed of light that is, of course, going the speed of light, the beam light, the light of beam? What do you think you see in that gap? Future past?
