Lawrence Krauss hosts a Halloween-themed podcast, debunking supernatural phenomena through the lens of "spooky physics." He begins by addressing ghosts, explaining that if a ghost is visible, it must interact electromagnetically, making it unable to pass through walls. Conversely, if it can pass through walls, it cannot be seen. This highlights a fundamental physical contradiction in ghost claims, exemplified by movie errors.
Krauss then discusses witches and magic, suggesting that Newton's laws, by demonstrating universal physical governance, undermined the belief in supernatural causes for events like bad weather. He criticizes the misuse of quantum mechanics, particularly the concept of "spooky action at a distance" (entanglement), to justify remote influence or the idea that consciousness can alter reality (as in "The Secret"). He clarifies that quantum observation is not tied to consciousness, and entanglement requires specific, prior interaction, not random remote influence.
Miracles are examined next, defined as events so unlikely they suggest supernatural intervention. Krauss argues that in a vast universe, statistically rare events are bound to occur, and human psychology, shaped by evolutionary survival instincts, predisposes us to attribute significance to coincidences. He uses the Lourdes cures as an example, showing that spontaneous remission rates for cancer are statistically higher in the general population than among pilgrims, challenging the miraculous interpretation.
Werewolves are dismissed due to the astronomical energy requirements for rapid mass change, whether through chemical processes or pure energy conversion (E=MC²). Finally, ESP and telepathy are debunked. Thoughts are electromagnetic impulses, which, if strong enough for telepathy, would be easily detectable. Weaker interactions like neutrinos or gravity are too feeble to induce thoughts in another brain. Krauss concludes that while the supernatural is fun for Halloween, the real universe, with its genuine scientific wonders like quantum mechanics and black holes, is far more fascinating and awe-inspiring than any fictional spookiness, and known physics consistently refutes these supernatural claims.
