The Space in Between
Space and Time is interchangeable. Look far enough into the universe and you will see the past staring back at you. The distance involved is astronomical. In order to visually re-live 1 single second that has passed, you must look past 3x10^8 meters - roughly the distance of 7 times around Earth. Such is the value of a single second.
Now, to bridge the gap of one year, that distance moves to 9.46x10^15 meters - enough to travel from Earth to Sun 65,743 times.
Is it any wonder couples with an age gap sometimes have a hard time communicating? To be so far apart as to render the term long distance relationship inadequate.
