Chopra’s moon comment exemplifies a common theme in quantum woo, that the bizarre phenomena of the quantum realm bubble up easily into our macroscopic realm of everyday life. This is simply untrue. Decoherence is so universal that once you start looking at anything much bigger than an atom, the weirdness starts disappearing. That’s why quantum computers and similar experiments are so hard to pull off. The high level of isolation or extreme cold required to demonstrate quantum behavior is exceedingly difficult to maintain.
