That forecast depends on dark energy and on which observational boundary is being discussed.If accelerated expansion continues as the standard cosmological model predicts, distant galaxies will become increasingly difficult to detect. This AI-generated illustration imagines that fading cosmic record; it is not a telescope photograph.
