Da Vinci's Salvator Mundi is the most expensive painting ever sold, at $578 million. If it was found to be a fake, its value would drop to about a dollar, immediately, even if the copy was impossible to distinguish from the original. Why would the original be worth 578 million times more than the copy, which nobody could tell apart? A secret key to unlock our whole culture lies in the answer to that question, I think.
