Our cosmological horizon.

Go figure, when the eventual cosmic collapse/implosion happens, we will never see it coming, because our local universe will have become the singularity that can not see outside of our very own event horizon. Even if a redshift velocity reduction is detected of the most distant galaxies, it'll be too late because of the 14 GY time delay. |
