In summary, there is a concept of a cosmological horizon in which light emitted by objects beyond it cannot reach us, but this does not mean that light is not affected by the acceleration of the universe beyond this horizon.

Is there such a thing as a light horizon where light is not effected by acceleration of the universe, and light can not reach us? a sort of no mans land.

EDIT.

The cosmological horizon satisfies the second part of this (light emitted by objects beyond our cosmological horizon cannot reach us), but not the first (light, and everything else, is still affected by accelerating expansion beyond the cosmological horizon).

As far as the title of this thread, there is no place where light "stands still" with respect to the expansion of the universe.

FAQ: Can Light Ever Stand Still in the Universe?

What is "A Place Where Light Stands Still"?

"A Place Where Light Stands Still" is a concept in physics that refers to a hypothetical location where light appears to be stationary, despite the fact that it is constantly moving at the speed of light.

Is "A Place Where Light Stands Still" a real place?

No, "A Place Where Light Stands Still" is a theoretical concept and does not actually exist in reality.

What does "A Place Where Light Stands Still" teach us about light?

This concept helps us understand the nature of light and how it behaves in different situations, such as when it passes through different materials or is affected by gravity.

How does this concept impact our understanding of time and space?

By exploring the idea of a place where light stands still, we can gain insights into the relationship between time and space and how they are affected by the presence of light.

What are some potential real-world applications of this concept?

While "A Place Where Light Stands Still" may not have any direct practical applications, the research and understanding gained from exploring this concept can lead to advancements in fields such as optics, astronomy, and quantum mechanics.
