Could We Create Artificial Universes?

Engineering artificial universes represents a potential final stage of technological development, shifting from manipulating matter within a cosmos to creating the cosmos itself. This process bifurcates into computational subverses, which remain dependent on a parent substrate, and physical seedverses, which pinch off into independent space-time. While simulations rely on processing power and hierarchical layers of reality, physical creation involves manipulating black holes or false vacuum bubbles to trigger new cosmic expansion. These endeavors raise profound ethical questions regarding the responsibility of creators toward conscious inhabitants. Furthermore, the pursuit of cosmological reproduction offers a novel solution to the Fermi Paradox, suggesting that advanced civilizations may prioritize the creation of new, enduring arenas for existence over the resource-intensive colonization of their own dying universe.
