Considering even the modest estimates of the size of the entire universe compared to the tiny sphere we can observe, I think it’d be pretty arrogant to think our spec is getting enough information to say anything about the universe as a whole is unlikely.
This isn’t really a counterargument to what he said. The limits of our observable universe is the CMB. It’s the beginning of the universe. The farther we see, the more redshifted it is, the farther in the past it is. Hot, dense, and redshifted is the CMB.
