How do we know for sure that the Universe is homogenous and not a patchwork of multiple 'universes'?

>>16744161 (OP)
yeah it's in the bible, retard

>>16744161 (OP)
We don't. For all we know outside our observable universe everything could be made of candyfloss and lemonade and there is no way to disprove it.

Im living the dream...youre just dreaming.

>>16744161 (OP)
We know what we're supposed to know for the time we're in.

>>16744214
That's not what I meant. How do we know when we observe the Bullet Cluster that it is in the same universe as us and that it's not in a pocket universe where the rules of physics are different?

>>16744161 (OP)
We don’t. We just have telescopes. Not like we can travel across the universe. We just assume it is. We have no actual proof.

>>16744253
We don't; universal physical constant is an assumption. This is one of the key underlying reason why cosmology can never be a science at a fundemental level no matter what era.
For all we know "stars" and "galaxies"..etc. out there are not what we think they are but something a lot smaller and a lot closer. Our current assumptions of these things are all based on the axiom that physics as we know here on Earth is the same out there.
But nobody bounced a basketball outside the solar system, so who the hell really knows.

>>16744214
Also this.

>>16744236
This is just tryhard nonsense lol. Like saying a piece of brown stinky shit has chemicals in it that would smell like clear blue water if nothing else existed. That's not even true! You first need a retarded stinky shit smeller like yourself, who you've pf excluded from your own retarded hypothetical.

Why the do you think we call it the OBSERVABLE universe you fuckwit

>>16744161 (OP)
Where is the complimentary lust provoking image?
I mean C-3PO is pretty hot but still

>>16744253
>where the rules of physics are different?
Not possible inside the whole universe. A parralel universe would be another story.

>>16746223
Does this satisfy your fetish?

>>16744253
Well that's much more interesting, you should have worded it like that. But uh yeah we can't reach other galaxies so at best we can try to infer if their behavior suggests so. This would probably collide heavily with the Hubble constant and CMB though.

No it's not, dumb fucking christcuck

>>16744253
We can see the emission spectra of distant galaxies and their gravitational lensing effects, and they seem to be consistent with the elements and models we have on earth

>>16744161 (OP)
because fuck you i'm not doing the math

>>16744214
Could it be made out of BBC?

>>16749514
Why would the universe be made of the British Broadcasting Corporation?
