The universe isn’t measurable.
This has always been the fact that has been standing out while reading or learning more about the universe and space in general.
Astronomy has always interested me, so getting a chance to write this article was a wonderful opportunity to once again get to know more about this field that interested me. When I told this to them, my parents started getting me more books and more materials.
And everywhere that I read the introduction of the books, it all mentioned these words.
“The size of the Universe isn’t measurable.”
“You cannot know how big the Universe is.”
“The Universe is expanding continuously.”
“We cannot know what lies beyond the Universe.”
Different strings of words, all meaning the same thing. All speaking the same language. The core of all studies so far has been only this.
“We cannot measure the Universe.”
Actually, we have been told this in so many ways, taught every single time that it has become a fact that we accept. Ironically, it is now considered a Universal Truth.
So no. We can never answer the question about how big our Universe is, for we don’t even know where the far other corners of our Universe lie, and we don’t know what lies beyond it.
We cannot even be sure that ours is the only universe out there!
(This deals with a whole new theory, a small proposition by a group of scientists who believe in the existence of multiple universes. The theory is currently known as the Multiverse Theory.)
Moving onto the next part of this question, you might want to first know that other than these common orders that mostly deal with celestial bodies, like planets and superclusters, we also have patterns that we have picked out in the stars, known as constellations and asterisms. On the day that I am writing this, it is the day of one of the most important astronomical days, where our Moon passes through four planets, though you can see it very close to Jupiter and Saturn if the sky is clear. The asterism known as the Winter Circle is going to be visible in the night sky soon.
This proves that there is a lot that is there in the Universe, and most of that is just our assumption and then too, most of the known Universe is unexplored.
If we take this into consideration, what lies near the edge of the expanding Universe would be out of this world (literally). But no, seriously speaking, we can never know what lies beyond these systems. We cannot even imagine what might be discovered, and even if we can imagine something, it will be hard to put into words.
For me? I am sure that what lies beyond will be incomprehensible for a mere human mind.
