comment Will the CMB ever stop shining?
@MSalters True, the CMB photons are finite, but so are the number of photons, atoms, etc in the entire universe, if the universe is itself finite. But the CMB will shine for at least as long as the universe is large (simplification).

Thanks to ticster for his extended explanation in chat.

Except that the CMB doesn't continue to emit. So, unless you can continue to receive CMB light from further and further away, you would eventually stop seeing it. This link shows that there is a point where you would no longer see certain present galaxies. I don't see why it wouldn't apply even to the CMB: en.wikipedia.org/wiki/…

I think I'm referring to the concept here: en.wikipedia.org/wiki/Cosmological_horizons#Event_horizon but I could be mixing up a few similar ones. Wouldn't the edge of the observable universe eventually overtake the CMB, due to the expansion of the universe?

Wouldn't it get to the point, though, where the CMB falls behind the Hubble horizon?

Except that they currently don't know how to make inflation stop, right? The equations point to an ever-inflating, bubbling, branching-off bunch of universes?

So, wow, one star really would've made a difference? I almost find it hard to believe but it's awesome.

Yes, I understand we're not talking about removing a star from the present. So you're saying if the early universe was missing one solar mass of mass-energy just after the singularity, you would have had a "Big Rip"?
