Cosmic Queries – The Fractal Universe with Charles Liu
Summary
Neil deGrasse Tyson, Gary, and Charles Liu answer cosmic queries on StarTalk, exploring why infinite energy cannot overcome the speed of light limit and discussing the Fermi Paradox. The hosts analyze the mathematical similarities between brain and universe fractals, clarifying that shared patterns do not imply a physical link or simulated reality. They also address whether the multiverse is a result of apophenia, explaining that quantum equations are open-ended rather than pattern-based. Finally, the team debates the plausibility of ancient civilizations seeding life across the universe, r…
