I was not able to get the info from that site. Does this require a subscription or special on-line reader program?

In any event, if the disappearance of mass behind the horizon which causes the loss of negative gravitational potential (on average), is equal to an increase of a positive potential at each point, then does this increase in potential energy (=mass?) at each point cause particle creation in otherwise empty space? Does the information lost behind the horizon return to us in particle creation throughout the rest of space?

I wonder if the big Freeze of galaxies that leave our horizon so we can no longer see them... what effect would that have on information content of the visible universe? Is that saying that information cannot leave our visible universe? The entropy, S=Q/T. If everything freezes at the horizon, then Q tends to zero, but also T tends to zero. Would Q include the rest mass which is energy?

Mike2, you may also find this of interest with regard to cosmological horizons

In a universe dominated by a small cosmological constant or by eternal dark energy with equation of state w < -1/3, observers are surrounded by event horizons. The horizons limit how much of the universe the observers can ever access.

Interesting paper. The authors note that if the U continues to expand, the CMB will eventually be redshifted into the noise of the Hawking radiation at the event horizon and the information in the CMB will be lost to us.
