Even though his own work led to it, Albert Einstein never cared for quantum mechanics concepts like entanglement, which he called “spooky action at a distance.” While there’s no doubt it is real, could something even more mysterious be hiding under it? We’ll talk with three eminent physicists and physicist/science fiction author David Brin about the Nova documentary on this subject. Planetary Society Chief Advocate Casey Dreier analyzes President Donald Trump’s recent tweet about the Moon and Mars, and Senior Editor Emily Lakdawalla introduces a new edition of The Planetary Report, now available to all.
