So if we are ever going to get anywhere we gotta go there much faster than light speed. We hypothesize faster than light(FTL), at inflation, lots of talk about tachyons and even a Big Bang episode with instant particle matching. But you want to pass intro, you better say something about the impossibility of mass accelerating to light speed. So what have You got to get us out there? My current imaginary ideas forms around gravities effect on time and times effect on light speed. In our gravity web, 186,000 miles/s is light speed but close to a black hole time and light move slower(?). So how about farther out, away from all this gravity. Could less gravity let time move faster and thus light move faster? If so, all we need do is control gravity... There is a very popular thread about the weird speed of light and other tangents to regard. So the goal is to have a craft that can move us around real fast. If you want to explain why this is a stupid idea and a waste of time, that too would be good.
