If light travels at different speeds through different mediums, then it's possible to travel faster than the speed of light. Just have the light travel through something like water or glass because light travels through those things slower than it does through space. So even though it's impossible to travel at light speed in space, it might be possible to travel faster than the speed of light through water, but in space. Or...if light travels at the light speed from our perspective, then we must be traveling at the speed of light from the light's perspective. Even better: If the edge of the universe if expanding faster than the speed of light from our perspective, then we must be moving away from the edge of the universe faster than the speed of light from the universe's perspective. From the universe's perspective, we are moving faster than the speed of light! [spoiler] Unfortunately, light would also be moving faster than the speed of light from the universe's perspective. Damn light :( [/spoiler]
