Study the painting and see if you can spot the spooky action manifesting itself in the space-time matrix.

Modern physics predicts an effect called quantum entanglement. Basically this means that the properties of particles that were created together remain entangled—even when they are later separated by great distances. This seems to violate causality, the speed of light and other common sense notions. In particular, Einstein considered such behavior impossible and in 1935 referred to it as “spooky action at a distance” [spukhafte Fernwirkung]. Many experiments have been done since then and they all seemed to confirm the principal of quantum entanglement. But the skeptics point out that all of these results have subtile loopholes. Finally in 2015 a confirming experiment was done that seemed to be loophole free. Or was it?

There is work being done to create very fast quantum computers based on the entanglement principle. Will this work? Who knows? The vast majority of physicists accept quantum physics—including the spooky action part. But as the famous physicist Richard Feynman famously said, “...nobody understands quantum mechanics”.
