Imagine Forever

We say it all the time, but we have no way of grasping what it really means. The Earth has been around for billions of years, humans for a short couple of thousand, and each individual person gets to stay for about a hundred if they're lucky. How can we, as humans, possibly understand what forever means?

Imagine propelling upward forever. FOREVER. Upward until you leave our atmosphere. Upward as you pass the moon. Upward as you pass an infinite number of stars, beginning with the one at the center of our own solar system. Upward as you leave the Milky Way. Upward as you leave the Milky Way, flying through uncharted, unowned, unseen, unknown territory. Upward as black fades to purple, then to blue, then maybe to white as you fly by stars that haven't yet been seen by the human eye. Upward you keep going. Forever. This is what forever means. Of course, you wouldn't make it forever. You would be dead pretty shortly, of course.
