I have no comment and thoughts about this article which I remember reading a couple of years ago. I just thought I would present a link to it, for those who enjoy reading about Quantum weirdness and spookiness. The article is well written and easy to understand if you have familiarity with the well known double-slit experiment which provides evidence of a photon behaving as both a particle or a wave depending upon how it is being measured (observed). If you are not familiar with this experiment, you might want to Google it prior to reading this article.
