Ok so we know the Earth isn't flat. Unless all the people who have sailed around the world etc. are lying.
But is the Universe flat?
Of course we might not know until we've sailed around it...

I've always thought this to be a fascinating question!
Obviously our Earth is round - bit wobbly here-and-there, but round - because we're
now able to see it all in the round.
Is the Universe round or could it be flat?
Fact is it probably could be any shape whatsoever because we're peering out from the inside!
I think it is our mind-thoughts that are preconditioned to accept that our 'thoughts' and everything we accumulate as knowledge, is round.
When you think about it, each thought or imagining has a boundary - a limitation to thought, and that limitation seems to form a sphere of any, and all possible forms of knowledge. If someone is particularly focused in certain skills in their thoughts or abilities in life, then their horizons might be spherically shaped overall, but with a wavy circumference around their personal sphere. i.e. a lot of variable or general held thoughts would form an
imaginary sphere, but maybe with someone who say studies in a particular field, or speciality, might well have a differently shaped imaginary sphere, or boundary - as to what might lay
beyond that boundary is anyone's guess.
As to weather
the Universe is round, or flat - with all the knowledge that is gained from this 'known' Universe, I guess you could say it may well be round, but it would only be limited to the way
we try to make sense of the things that surround us including space itself?
