c, or the speed of light, is the speed of which photons travel in a vacuum, A.K.A. the fastest speed in the universe.
To travel at/exceed this speed would result in breaking the fabric of space-time.
c = 299,792,458 meters per second = 671,000,000 miles per hour
The new spaceship, Exr-C2 can travel at 0.6 * c (light-speed), or 60% of the speed of light.
Crystal light is the process of taking crystal light and shoving it inside of your asshole. Then you start creaming out of your butthole and the cream is flavored and you start boxing it up and shipping it out to people labeled as flavored whipped cream.
