Cosmic Paradox Reveals the Awful Consequence of an Observer-Free Universe

Theoretical physicists applying quantum theory and gravity to model universes discovered a startling paradox in 2019: a closed universe mathematically identical to ours appeared to have only one possible quantum state, lacking the complexity needed for stars, planets, or life. Recent research suggests this paradox may resolve by including observers, whose presence as boundaries within the universe restores all the missing complexity and information.
