Hi, My name is Jim. I found my way to this forum during a "Where is this going to take me" Google spree on the topics of "Source-less Gravity", "Photon Decay" and "Light Cone". I am a retired computer programmer, but also having degrees in biology and psychology. I am using my retirement years to finally write about my life-long passion...the origin and destiny of the Universe, which deals with the concept of creatio ex nihilo and the pre Big Bang state. My foundation in physics is basically self-taught and my approach is philosophical.
