In other words, existence of the universe?
I see spacetime is a concept that applies to an measurement of an aspect of universal existence, I'm not sure a concept can be called timeless.
I'm not sure I see spacetime as being a 'concept'. As I am using it, spacetime is the inherent four dimensional geometry of existence.
Beginnings and endings apply to finite observed aspects of universal existence..
But the words 'beginning' and 'ending' only make sense if there is time. To say that something has no beginning or ending implies that time is infinite in duration.
Universal existence is one, all apparent parts are observed conceptualizations.
Again, I see no connection between that and what you wrote. What 'paths' are you talking about?
By timeless, I mean it is beyond measurement as a time period because there is no beginning and no ending.
So an infinite interval of time, by your definition, would be timeless? That seems like a strange use of the word.
Correct, terms like velocity, volume, charge, etc., are concepts that help us understand observed phenomena, but there is no real entity as such.
Here I will strongly disagree. We have those concepts because they help us describe reality. They only work because they have reality.
Now Polymath, I appreciate your gist and the workings of science to learn more about the universe, I just threw my more philosophical non-conceptual observations out there, not to try and persuade you otherwise, but to express the way I apprehend the universe in what I see as a different, but valid (to my non-conceptual state of mind) manner. Thank you for your understanding, my view is not the scientific way and I understand that.
I'm attempting to figure out your system, but it makes no sense to me. Possibly because of my training and the fact that we seem to be using some words very differently ('timeless' for example, 'eternal' for another).
When I say 'timeless', I don't mean simply not having a beginning or an end (which may happen even with time), but that there is no time dependence at all.
When I say 'the universe', I mean all of matter and energy throughout space and time. Time is *within* the universe, not something external to it.
The word 'eternal' tends to be ambiguous. It can imply that there is an infinite duration of time OR it can simply mean 'throughout all time'. In the second version, if time had a beginning, then 'eternity' did as well. If time has an end, then eternity does as well. The first version (involving an infinite time duration) may not be reality.
