Would objects near the edge of the observable part of our universe recede past our horizon?

DLM -

It depends on the effects of dark energy. All of the objects that we can observe are by definition receding at less than c. Therefore, the light from those objects will continue to reach us at c relative to us, unless their recession is accelerated. The light will continue to get dimmer with distance, and I suppose that eventually they will disappear within the noise level of the cosmic background, but I see no other mechanism that would result in their loss over the observable horizon, unless they are carried away from us at greater than c by a continuous increase in the rate of expansion of the space between us (not the same as a relative speed greater than c within a fixed space).

ADDED: Another net result of such an acceleration would be a steady increase in the observed wavelength due to redshift. I guess the definition of the horizon would be when the wavelength reaches infinity, and the frequency hits zero.

Per General Relativity without the cosmological constant (or anything similar)? No. Gradually, more and more of the universe would become visible.

If you add in dark energy, maybe. What is visible would gradually recede. Funny thing, if you have an acceleration in one direction, you create an event horizon behind you. Not a black hole, but simply a place where you cannot see past. If the acceleration increases, you see less and less.

It's common sense to realize that if such objects are *at the edge* of the observable universe then they're still visible. Of course their light has taken some 13.7-billion years to reach us and in that time those objects have moved beyond the visible horizon. In real time, they're beyond the horizon.

specific gravity result falls off with the inverse sq. regulation and of all forces gravity is the weakest. There seems to be no longer adequate count number to arrest the accelerating advance of the universe. the only way we are in a position to locate a super gravity result previous our observable horizon is to observe products @ the sting what they are doing. Astronomers have postulate from observations a team of galaxies that are rushing in direction of our observable horizon and have dubbed a super merchandise via fact the super Attractor that's previous thirteen.7 b gentle yrs away

Yes. All objects in the universe are bascially moving away from each other. So it stands to reason that if and object is near the edge of our universe AND its moving away from us then it will become Not visible.

If the expansion rate of the universe were sufficient, yes.

Otherwise, objects currently beyond our horizon would become visible to us.

not a chance unless it is older then 13.7 b years and that can not be

no
