This is the blurb:
The universe dies a slow death. In many billions of years, humanity has spread out over many galaxies where it exists as a group of immortal consciousnesses. Its greatest grief is the fact that no other intelligent life has ever been found. Its greatest hope consists in the plan to destroy the universe and wipe out itself with an artificial big bang that might result in a better cosmos. Everything is set for a grand finale - but then something happens that nobody expected. And humanity must re-consider itself and its whole existence.

The cover should show the beauty of the universe and the hopelessness of humanity. It should be fascinating to look at, transporting a certain wow effect.
