I had to back up a bit. I was warned at an early age that contemplating this stuff would lead to insanity, so I gotta be careful. Just to review, there are three and only three things: Time, Space and Matter. (Mass and Energy being a subset of Matter.) So, that is that, Time, Space and Matter. Another subset of Matter is “organic matter”. I am organic matter that God gave consciousness and free will. I think, therefore I am. (You may be a figment of my imagination, but that is a discussion for another thread). The way that I have trained myself to look at it is this: there is me, there is what my senses reveal to me, and there is what I make of it. And this can apply to humankind as well. There is us, there is what our studies reveal to us, and there is our cumulative interpretations of those studies. Different cultures over different times have come up with different conclusions. Those conclusions are also available for us to draw upon. Yet, there is still only three. The observer, what is observed, and what the observer makes of those observations. I call these the three “realities”. It also ties in to mind, body and soul. Or heart, head and spirit. The physical, the mental and the spiritual.
As for “dark matter”, this is only something that comes to my awareness via scientists and the use of their current set of measuring instruments. I need to somehow pigeon-hole it. For scientists, unfortunately, I only see that they have two realities - themselves and the findings of their observations. And that is all I have to say about that for now, because my wife just handed me a grocery list.......
