We, adult humans, have bodies with a size between half a meter (a "dwarf") and 3 meters (a "giant").
We don't have bodies that are one nanometer high.
We don't have bodies that are one light-year high.
So, how the "human scale" affects our perception of the Universe?
An atomic nucleus seems to be "very small" to us. A galaxy seems to be "very big" to us.
If we were one nanometer high, would we think an atomic nucleus is very small? Would we be able to perceive things that are much smaller than a quark?
If we were 50 light-years high, would we think a galaxy is very big? Would we be able to perceive how small the "observable universe" actually is?
By the way: no, I'm not on drugs...
When I see deep space photos with multiple galaxies appearing like star fields, it is hard for me to believe that the scale would seem small regardless of the size of the organism observing.
I read somewhere recently that there are more atoms in a grain of salt than there are stars in the universe. It that's true, then I guess I never realized how small atoms might be. And there's no way I can imagine traveling at the speed of light, and yet that measure is thrown around all the time.

Well, what if the entire observable universe is just inside a marble ball of some kid?
If the organism observing was that kid, then it would seem small...
So, what drugs are you on?
Just messing with you.
here's a hypothesis. As you look into areas of universe, progressively more and more remote from you, everything accordingly is getting smaller. But, because of the distance, to observer, it actually appears proportionally sized.
Forgot the big name to this idea, but it sort of relates to what you asked - a universe in a bubble. So we, actually, exist on the inner bubble surface and the rest of the universe is going towards the center of that bubble, with everything in it progressively getting smaller. When you start traveling towards those areas, YOU become progressively smaller too, so for you, as observer, this is not noticeable.
You can do a very simple experiment to see how it works. Take a bunch of ball bearings and toss them into a bowl. You will notice, that bearings are reflected in themselves but then, those reflections reflect themselves again, and again, and again, progressively being smaller and smaller.
Found it. Multiverse. Read on it.
Ahh, I see. You may also read Stanislav Lem's beautiful SciFi story on this topic. There are plenty of similar concepts in various flavors.
But the thing is, for our purpose, it does not really make any practical difference, does it? Outside of quite idle discussion we are going to have here, what does it really matter?
You may also look up Universe in the Box theories. Refer to Bible, as in Bible it mentions "firmament" Earth is enclosed in.
As I said - lots and lots of fantasies on this topic. Pointless.

I don't think that searching the truth is pointless.
It could be impossible to know for sure today, and even for many years in the future.
It could not have any practical use ever.
But I don't think it's pointless... Knowing the truth is never pointless.
I remember when I was a kid and found out the North Star we see is as it was 435ish years ago.
Mind = Blown
Let's face it guys...we are dust in the wind (and that's giving us too much credit).
