You caught me :shy:.I said this half out of friendly banter and half out of frustration. In posts 49 & 53 you gave a link to a Wiki article and a brief description that was a copy and paste from the article itself. What you copied and pasted was William Keel as quoted by Wiki. I had never heard of the man before you quoted him so when you asked me who he was, ... It made me wonder if you paid any attention to the article that you were linking to/quoting in the first place.
We may be just having a passing discussion or we may become friends and discuss issues openly, but either way I will learn as we go. William Keel is a good example. I have known what the Cosmological Principle was for a long time, every since I found out there was a standard cosmology, the cosmological consensus, Big Bang Theory. I characterize BBT as the General Theory of Relativity, Inflationary Theory, and the Cosmological Principle. When I discuss the cosmological principle with someone new I like to link to a description of it. I Google it, go to one of the top links, look for the words that describe the principle as I like it described, and use that link in my post. I didn’t bother to actually read the Wiki page except to the extent that I saw they had what I call the right description of it already set off in quotes so I cut and pasted those quote. I didn’t even see who they were quoting so you and I both got introduced to Keel at the same time. I did find his Url interesting and will probably look into his galaxy formation ideas and compare them to what I have gleaned from my studies.
Yes, the reality that we are part of is the most important to me too. Part of the reason for my stream of threads is to find people willing to discuss topics that I’m interested in and pick their brains and get their view of cosmology. You are just the kind of brain I like to pick because you have thought through your views and have them connected and consistent. The fact that you may not be fully aware of different views means that you have been at this for maybe a couple of years to get as good as you are on your personal view but haven’t had years and years to explore other cosmologies. But your particular view is very current.As far as I know there is only one reality that matters and that is the one that we are participating in. Could there be more than one reality? I guess so, but if there is then I am led to believe that they all originated from the same point as our reality. In all honesty, I don't know enough about these concepts to either support them or refute them.
Space being able to stretch is an abstract concept (it stretches where you say it stretches). Even though you can stretch it as far as you want as if space could be compared to the surface of a balloon, then the existence of one balloon does not eliminate the existence of two balloons (or a potentially infinite number of balloons).Space is being stretched, not created. A point in space is an abstract concept (they exist where you say they exist). Even though you can place more points on an inflated balloon than a deflated balloon does not mean that you created more latex.
So we are on the same rubbery latex so to speak .
Are you familiar with how spacetime geometry and a relativistic coordinate system correspond to reality (maybe better than I am)? This is just my layman’s view but gravity in spacetime is accomplished by geodesics and Einstein’s Field Equations take into consideration the influence that the presence of mass and energy has on the curvature of spacetime. There is no physical connection and every motion is determined mathematically. There is no physical observation that confirms that spacetime actually exists and can be curved by mass, only mathematical equations thought they are very accurate (but not perfect of course).
The reason there are no observations to confirm or falsify curved spacetime is that we cannot examine the curvature, only the predictions that General Relativity makes via the equations of how mass/energy would curve spacetime and affect the motion of objects through curved spacetime. We also cannot confirm that there is a graviton or gravity waves by direct observation but the standard particle model and particle theory predict them.
If spacetime doesn’t actually exist then there would have to be other explanations for what we observe and that is where my interest lies at the moment. I have a personal distrust of spacetime because it requires spacetime to originate with the Big Bang and requires space to originate from a point and stretch as you put it. My pea brain must have some explanation for how space is not just everywhere and what logic or fact is there that it has not always been everywhere. You don't have an answer that you are holding back do you?
The nature of energy, energy density, energy density limits and thresholds, and speculation about the causes of the Big Bang and the initial expansion of our observable universe are my interests. Having and understanding alternative explanations for many of the "proofs" of BBT is another interest and I have a few alternatives.
Feel free to follow my threads and jump in anywhere you like to give me your view. I am trying to imagine the nature of the universe from the perspective of other coordinate systems and other cosmologies. You have done a good job of conveying your cosmology and I will refer to it myself in the way you describe it when I am in the Spacetime mode.
