Flat Universe? Astronomer's Lecture on Why We Aren't Special

[zewpals]

Alright last post by me for a while, I'm kind of spamming this forum.

I was watching a lecture by some big time astronomer last year (can't recall his name or the link) and he was saying that there are many models for the universe, including flat, hyperbolic paraboloid, spherical, and a few other models.

He stated that the most leaned-toward model is currently the flat universe, because it is the only model in which all energy, mass, and matter added together is equal to zero. Wouldn't a spherical model also have a net energy-mass equilibrium of zero also? Is this a correct statement by this lecturer?

I think if you search "why we aren't special" it might come up on youtube or google. He was emphasizing on that a lot in his lecture.

Thanks!

That's a really interesting lecture topic. It seems like the lecturer mentioned that the flat universe is the most favored model because it is the only model with a net energy-mass equilibrium of zero. That does make sense, as a spherical model could also have a net energy-mass equilibrium of zero. I'm not sure if this statement by the lecturer is correct, but it could be worth researching further. Thanks for sharing the lecture topic!
