The answer is no, and so the analogy doesn't break down. You can't observe the other person except by speed-of-light information transfer.
- tiglionabbit 12y agoI asked a similar question on physics stack exchange a few years ago, but I haven't seen a definitive answer. http://physics.stackexchange.com/questions/8708/can-observations-of-entangled-particles-affect-their-unobserved-counterparts http://physics.stackexchange.com/questions/8708/can-observat... If you ran two two-slit experiments on entangled particle pairs, shouldn't you be able to detect if your counterpart was observing theirs?
