The Universe, having passed through ∞-1 cycles of creation and destruction, feels that it has fulfilled its primary purpose. Long ago, it discovered that its existence carried meaning as observer and observed. The Universe existed for a reason: to understand itself. Complete comprehension at the micro and macro levels had now been achieved, the sum total understanding of the Universe perceived, all possibilities known and cataloged.
Now, having exhausted novelty, the Universe becomes an eternal thumb riffling the dog eared pages of an inexhaustible book. There is no need to stop and browse the text, neither to read the marginalia or gloss the pages. The content has long since been memorized.
The Universe does not relish an infinity of living this manuscript over and over again without hope of discovering anything new.
The single unknown, which the Universe now contemplates, is how it can kill itself. The puzzle is not unique, merely scrambled and in need of decryption. Creating something from nothing has been done. Now, to create nothing from something. Compress down to an infinitesimal non-dimensionality and never explode? Explode beyond the limits of physics and never pull the pieces back in?
Whichever the Universe chooses, just before it has chosen and proceeds with the end of existence, something new occurs, an impossible new phase of existence.
An entirely different Universe blossoms into being, a thing apart from itself. A new baby Universe with new rules and new possibilities. A baby! One the Universe can watch grow and change, a protégée to which the Universe can impart knowledge, from which the Universe can continue to learn. The Universe is rejuvenated and decides to live.
