Could it be that we are totally wrong, and the Universe isn't as big as we think/say it is?

I think you are missing several orders of magnitude for a beach ball. More like micro organism and the size of the Sun.

I was afraid I would.
My first example was a tennis ball.
But you get my point, I hope.

I think it is bigger.

OK, but what’s on the other side of that beach ball?

The other side of beach ball is 93 billion light-years, 8.8×1023 kilometres or 5.5×1023 miles across . . . ..So tell me in 94 BILLION years when you get there @Dutchess_III.

My point is, The universe can’t be limited to one fixed point in space. There is always something else on the other side.

No. It is as endless as time itself. And your imagination.

Is the universe big or small? It depends on what you compare it with. The observable universe is 90 billion light years in diameter but the actual universe is 1,000 times larger than this. It’s just that we can’t see it as its light will never reach us.

Ooh you are so big, absolutely huge, we’re all impressed down here I can tell you.
No, that’s not Ron Jeremy’s first girlfriend…ya dirty bastard.

The vastness between sub atomic particles and the edge of the observable universe is incomprehensible to humans.

Even if only proportionally the Universe is still that big to us, so…

“Man is the measure of all things” says the Poet.

Trouble becomes when one Universe ends another begins, and until man physically can decipher, then its all conjecture and subjective.

@rebbel is correct in thinking it’s unlikely that the universe isn’t as big as this topic isn’t deep.

Possible, sure: the observations and measures could all be wrong, deceived by something or someone; and there’s nothing wrong with asking. But I’m going to hang in with Hawking, Sagan, Tyson, et al., on this one. Since I’m not doing the research and study myself, it becomes a matter of confidence, and I have confidence in them.

What do they say about it @Jeruba?

There’s an interesting discussion on the topic here

Thank you, Jellies.
Thank you, @flutherother,I’m listening to them right now!
