👉 Existence engineering refers to the theoretical and practical approaches aimed at creating or sustaining conditions for the existence of entities, phenomena, or systems that may not naturally occur or be observed in our universe. This field explores the manipulation of physical laws, quantum states, or other fundamental parameters to enable the emergence of complex structures, life, or even alternate realities. It encompasses speculative ideas like creating habitable exoplanets, engineering black holes for energy extraction, or designing artificial universes. While rooted in theoretical physics and advanced technology, existence engineering remains largely speculative, challenging our understanding of reality and pushing the boundaries of what is scientifically conceivable.
