A variation of Dyson sphere.

A variation of Dyson sphere.

This and other futuristic ideas by cosmologist Max Tegmark (known for his Mathematical universe hypothesisOur Mathematical Universe: My Quest for the Ultimate Nature of Reality) in this interesting Discover article (extracted from his book Life 3.0: Being Human in the Age of Artificial Intelligence) that I just stumbled upon:

Thirteen point eight billion years after its birth, our universe has awoken and become aware of itself.

From a small blue planet, tiny conscious parts of our universe have begun gazing out into the cosmos with telescopes, repeatedly discovering that everything they thought existed is merely a small part of something grander: a solar system, a galaxy and a universe with over a hundred billion other galaxies arranged into an elaborate pattern of groups, clusters and superclusters. Although these self-aware stargazers disagree on many things, they tend to agree that these galaxies are beautiful and awe-inspiring.

But beauty is in the eye of the beholder, not in the laws of physics. So before our universe awoke, there was no beauty. This makes our cosmic awakening all the more wonderful and worthy of celebrating: It transformed our universe from a mindless zombie with no self-awareness into a living ecosystem harboring self-reflection, beauty and hope — and the pursuit of goals, meaning and purpose. Had our universe never awoken, then it would have been completely pointless — merely a gigantic waste of space. Should our universe permanently go back to sleep due to some cosmic calamity or self-inflicted mishap, it will become meaningless.
