I added a section about the evidence for the afterlife that comes from quantum mechanics to my web site:
When physicists study matter at the atomic level, they find that the properties of matter are not determined until a conscious being percieves that matter. This demonstrates that physical matter depends on consciousness for its existence and therefore consciousness cannot arise from matter. The brain, which is composed of matter, cannot produce consciousness so consciousness must have an existence independent from matter. While this interpretation of quantum mechanics in not universally held by all physicists, some of the original founders of quantum mechanics, including Nobel Prize winners in physics such as Max Planck and Erwin Schrödinger, believed this.
