53. As Fast as the Speed of Light
We all know light photons are the fastest traveling energy bits in existence (that we know of), and reaching such a speed with something that has mass is nigh impossible due to needing an infinite amount of energy to power it.

But when you take all that into consideration and realize that while one beam of light can travel around the earth seven times in a second, and that one beam would require four years to reach the next star at that same speed, it makes you realize just how far the nearest star is.
