Lot of information there to absorb, but real interesting. If the universe is inside a gravastar, what's outside the gravastar? Is that sitting in a universe of its own? Some of these theories may not be as extreme as they sound. I think anything's possible.
The idea that our universe might be inside another lifeform isn't so far-fetched. After all, each of us had a mother, why not the universe as well.
