It's an existential question that most of us have probably pondered at some point: is space infinite? This is difficult to answer because there is not just one kind of infinity to consider. Even if the universe continues forever, it may not be infinitely large. It could be bounded like the surface of the Earth, allowing you to travel indefinitely without ever finding a limit. Say no to plagiarism. Get a tailor-made essay on “Why violent video games should not be banned”? Get the original essay The universe may be infinite, but we can only see a finite part of it due to the limited speed of the light. We can only see the parts from where light has had time to reach us since the beginning of the universe - which means we can (in theory) see a spherical universe with a radius of around 47 billion light years. If I gave you time to think about it, I'm sure you would come to the following conclusion: "this means that the universe must have expanded faster than the speed of light at some point", which appears to violate special relativity. . In fact, this is what would have happened, during a period called "inflation", and this does not violate special relativity since it is not a question of spatial movement, but of expansion of space itself. In human terms, that means 13.8 billion. light years in all directions, the Universe does not repeat itself. Light has been traveling toward us for 13.8 billion years here, and 13.8 billion years there, and 13.8 billion years there; and it was just then that the light left these regions. The expansion of the Universe transported them 47.5 billion light years away. Based on this, our Universe measures 93 billion light years. It’s an “at least” number. It could be 100 billion light years, or a trillion light years. We don't know. Maybe we can't know. And it could well be infinite. If the Universe is truly infinite, then we obtain a very interesting result; something that I guarantee will break your brain all day long. Consider this. In one cubic meter (or yard) of space. Okay, in a roughly large box of space (show with hands), there are a finite number of particles that can possibly exist in that region, and these particles can have a finite number of configurations given of their spin, their charge, their position, their speed and so on. There are only 1080 particles in the observable Universe, so that's far fewer than the possible configurations of matter in a cubic meter. If the Universe is truly infinite, if you travel from Earth, you will eventually reach a place where there is a double cubic meter of space. The further you go, the more duplicates you will find.

And at least one of them will have a beard.
