Great article again David Bates. I am however still puzzling over the idea that reality is what we choose it to be. "Physicists have long known that a quantum of light, or photon, will behave like a particle or a wave depending on how they measure it. Now, by bouncing photons off satellites, a team has confirmed that an observer can make that decision even after a photon has made its way almost completely through the experiment—seemingly well past the point at which it would become either a wave or a particle. Perhaps what we call consensus-based reality has caught up with UFO's?" No answers yet but an interesting puzzle nevertheless.
