The Universe?

Sometimes I stop to think about the universe as we know it. What is it and what does it mean? The reality is that no one can possibly claim to know the answer. We can only see what we see, and even then we may not know what we are seeing. Basically, we will never know the truth but we can ponder the possibilities.
The first thing I want to know is how much space does the universe contain? Either it is unlimited or there is a limit (duh). It’s easy to believe that it is unlimited, since it is hard to imagine a limit to space. What would be beyond the end? How can there be nothing? Or maybe the limit is there but constantly changing, so there is virtually no limit.
A recurring thought that I have is that the universe is just part of one layer of infinite layers of realities. Maybe the universe we live in is just a tiny particle of a much larger universe, which is in turn a particle of a larger universe, and so on. If this is the case, then every particle of every atom in this universe is itself an entire universe. In short this is an infinite recursion.
Think about that. Every one of those billion trillion gazillion atoms in your body might contain a bunch of universes. But don’t think too hard about this or your head might explode…


I’m not sure whether we can know space is or isn’t anything at this point, it might be indeterminate. A particle/wave can be in more than one place at once, or in an indeterminate place. If the most fundamental pieces of the universe can be indeterminate, what does that say about the entire universe as a unit? I dunno, crazy. When our logic no longer applies how are we supposed to observe & describe things? Philosophy of science & metaphysics are fun.

Yeah, it’s crazy. We don’t know anything…
