[week 71]

"eventually the universe will accelerate so rapidly the more distant galaxies we can see today will move away faster than the speed of light and will disappear over the horizon."

I know some of the physics euridites on FR might understand how this is possible, but I thought c was the upper limit in speed, save gravity, which is a force and quantum events.

RadioAstronomer will correct me if I'm wrong, but if you think of it like a balloon, it makes sense. C would be the max speed you could travel over the surface of the balloon, but it does not have anything to do with the rate of expansion of the balloon, which is what actually causes the galaxies on its surface to move apart.
