Hello.(adsbygoogle = window.adsbygoogle || []).push({});

First of all, I must say that I'm new to this forum, so I apologize if I'm posting in the wrong section.

I'm a 17 year old with not that much knowledge about physics, so if what I'm talking about makes no sense or is completely stupid, just let me know.

A couple of days ago I asked myself:Is it possible to say what percentage of the universe do we know?(note: I'm talking about the whole universe, not just our observable universe)

At first I said that it is not possible to answer such question since it implies that we know what 100% of the universe is. If the universe is, indeed, infinite, that means we can do some math, as 100% = infinite.

No matter what value we give to X, the answer will be the same, that is infinite. With this in mind, does it mean that what we currently know about the universe represents an infinite amount? And if so, it means that, as X increases, the result will still be infinite. That means that no matter how much we progress, how much more we learn about the universe, we will still know as much as we currently know... which doesn't really make sense, since we obviously increased the amount of information we have about it.
