Contemplating the unknowns must be one of the greatest hobbies of generations of human. Indeed, things like the universe have always been mysterious to human. The enormous difference between the tiny world we live in and the vastness of time and space, however, does not stop us from trying to uncover bits of it. One big question that has kept scientists of many generations up at nights to find answer is what exactly exists at the end of the universe. Can we expect the universe to expire at some point in time?
Of course, I’m not an astrophysicist, and they are usually the ones with technical answers to all the big questions that can sometimes annoy us on the odd occasion. Thus, if I could choose, I would travel to the end of the universe to see what’s going on over there. Possibly, if I kept travelling non-stop, to the very depth of space, I would eventually hit some sort of “brick wall” that blocks me from traveling further. Besides, Frank Donald Drake, a famous astrophysicist, has developed the Drake equation used to detect the number of extraterrestrial life in the universe. Apparently, if one among a billion planets has intelligent life, there must be over 6 billion planets with intelligence on them. Therefore, on my way to that “brick wall” end , there is a big chance that I might even com across some random planets with blue creatures and end up staying there a few days.
There are so many possibilities of what we might encounter at the end of the universe. It’d be astonishing if I took all that time to travel and found out that our universe comes around in circle, meaning if we try to travel to the end of it, we will just end up back at the beginning. Our universe is possibly nothing but a huge pile of matters with no clearly defined edge or boundary; or maybe it is just light and energy expanding as modern theories say. Or what if the end of our universe is the beginning of another universe that has its own separate history and law of physics?
Anyway, no matter what exists there, this will no doubt be a fun journey to take on. And do not worry about starving to death when we reach the destination, because Douglas Adams said in his Hitchhiker’s Guide to the Galaxy that there is at least one restaurant over there…
