What does Brian Greene mean when he claims we wont have the ability to observe light from distant stars due to the universe expansion
Brian Greene within this TED discuss attainable multiverse, claims tomwards the end (At about 18:00 mark) this statement. 'Because the expansion is speeding up, within the pretty far future, those galaxies will rush away so speedy, we wont be able to see them, not as a result of technological limitations, but because of the law of physics.'
This seems to me against the fundamental premise of relativity

He indicates that the stars will fall into our cosmological horizon. This really is like a black hole horizon
Nike Blazer Pas Cher, except surrounding us, and in our present understanding, the accelerating expansion on the universe means that the cosmological horizon will only expand to a finite area and after that cease. When it stops, anything far away from us will likely be sucked into this cosmological horizon and disappear from view.
I favor to state it this way, since this is a picture that is constant with staying inside a single causal patch
Nike Blazer, and it is actually constant with holographic principle and with logical positivism. There is absolutely no require to postulate anything beyond what we can see, as well as the cosmological horizon would be the boundary of what we are able to see.
In the far, far future, if string theory is usually to be believed, and if our existing understanding of deSitter spaces is precise, our universe will decay into one more vacuum state which doesn't have a cosmological horizon. This will be a catastrophic event, destroying all the matter in our universe beginning from some nucleation bubble of your new universe.
