I wouldn’t consider Brian Greene a pop physicist. Greene: “The past, present, and future are all equally real. They all exist.” Check it out: http://www.youtube.com/watch?v=yqzgYRBlslw about the 27 min mark, plus and minus. This a segment called the “Illusion of time” from his series “The Elegant Universe.” Sean Carroll, CIT, agrees. Max Tegmark, MIT: “The past is not gone. And the future isn’t non-existent. The past, present, and future are all existing in the same way.” I heard you follow theoretical physics so I thought I would get your take. Most political types are oblivious to this stuff.
