No one can escape friction, not even in a vacuum.

On earth, we're slowed down by the muck of the everyday world. Matter slows us down, rubbing against us and taking away our speed and power. Gravel, air, even slip-n-slides, exert some friction on us. This frictional force runs counter to our motion, and it can't be escaped anywhere on earth.
