So, if you look out far enough in an expanding universe, you come to a point where the galaxies are moving from you at the speed of light. Amazingly, the distance to that point never changes!
So, at a distance of ~15 billion light years, things are moving away at the speed of light, BUT also, it will
always be that way,
for all time!!
In every direction, galaxies move beyond the point where they recede faster than the speed of light. We are thus surrounded by a 'Cosmic Horizon'. No signals can ever reach us from beyond that horizon.
Its just like we live inside a black hole !
Apparently, the mathematics of cosmic horizons are similar to those of black holes !!
Just as black holes radiate (and allow information to escape), so do cosmic horizons. However, their radiation, (or information bits),
is inward ..
not outward .. and that's where the hologram bit comes in !!
Amazing ! .. Formally, this would be called the "Cosmic Principle of Complementarity" …

To an observer inside a cosmic horizon, the horizon is a hot layer composed of horizon-atoms that absorb, scramble, and then return all bits of information. To a freely moving observer who passes through the cosmic horizon, the passing is a non-event.

I think I get it, now. Absolutely amazing !! Very cool. I think I'm just about done !!
Comments welcome .. am I loosin' it ?
Cheers
