Yes it does have a subjective quality, because there is not a single identical experience of the atomic reality that can be used as a experiential baseline existence. This Universal axiom is identified by Einstein’s concept of Relativity.
No brain is identical to another brain and it is only by consensus that we agree on some limited generalities from the infinite number of experiential patterns .
We have set “standards” which addresses the Human relational experience of certain commonly observable patterns. But those standards are always provisional (by common (agreement), because of our limited ability to experience all of reality.
If we could we’d go instantly completely mad,
The terms “Time” and “Spacetime” are human terms, for human use, but have in and of themselves nothing in common with the universe at all. The Universe has no language other than mathematics.
Just take the terms for communication purposes, ok? All of human reality is by agreement on observable patterns including the symbolic literary or scientific languages.
The universe can exist without us, we cannot exist without the universe.
Thus we arrive at the distinction between your Human Mindscape and Physical Reality.
I bet our mindscapes are very much the same. I try to remove (or qualify) all human symbolism from my objective analysis of universal properties and functions.
That is difficult because the only way humans can communicate with each other is via human symbolic language and then it is assumed that the speaker is speaking from a human perspective. I believe the term is anthropomorphism.
Basics of Anthropomorphism
Anthropomorphism is the attribution of human characteristics to nonhuman entities, objects, or concepts. It results in ambiguity or misleading communication and thus should be avoided in APA style. However, common usage in academic writing includes some phrases such as “the results suggest” that, although examples of anthropomorphism, are acceptable for use because they do not lead to confusion.
This is why I always qualify all human symbolic language as such. But if humans can symbolize a universal property, function, or constant, it does “suggest” that these things are in fact part of reality, regardless of the label we attach to it.
