It's estimated that there are roughly 10^23 stars in the visible universe, I don't really know how they extrapolated that number, but it's really big so I guess that's fine

I didn't say I know, but that's nitpicking, good point. Every second the universe get's bigger for all we know.

Some people even believe Steve Jobs created the galaxy

And there's the thing about being able to estimate universe's size as well

They estimated the mass at the big bang, and the expansion of the universe, the cosmic x-ray ... and then said, 'F#ck it," and added Dark Matter to fill out the numbers.
They do not know, do you count clusters, dwarf galaxies, can they point to the centre of the universe?

No there is no center of the universe because it didn't happen like they portray it in popular media (actual bang spreading form one point). The space started to expand, actual space you live in, therefore there is no center of the universe.
It's kinda hard to imagine I admit but that's the experimental fact...

Depends, there is theory that the universe expands and contracts and the big bang has happened a couple times. But if one goes with the four dimensions erupted at the moment of the big bang. The universe dispersing from a point. Experimental fact? WTF, simulated on a computer. Haydron Collider might get conditions just after the Big Bang. They cannot even agree on the age of the universe.

STR and OTR  Plus observable facts from satellites that recorded background cosmic microwave radiation.
So yeah theory supported with good facts
And we do agree on the age of the visible universe. What we cannot see doesn't really interest us, I mean, that falls under the provision of philosophy not physics
