  • -  A hand drawn diagram from Carl Sagan representing all of space and time. The X axis represents time, going into the future and into the past and the Y axis represents scale, from the size of the electron to the distances between galaxies. It marks the relatively small "realm of direct human experience" and the much larger "realm of quantum physics" and "realm of special relativity."
