My choice is all of the above. Imagine a nothingness. From which perspective or perspectives are you viewing or in some other way experiencing the nothingness?
From the future, since the nothingness is clearly behind us. Our paradigm of spacetime has been tested and found consistent with all the evidence, so it stands as a canonical theory upon which to build. Our only point of uncertainty is at the moment of the Big Bang itself. This suggests one of two corollaries:
- 1. Time has an Absolute Zero, which is consistent with other measures of the universe such as temperature. On the other hand this could simply mean that we're measuring time wrong, using an arithmetic scale instead of logarithmic.
- 2. The Big Bang was not a singularity and similar events occur at rare intervals.
From some perspectives it is easy to imagine matter and from other perspectives it is easy to imagine god.
The paradigm of matter and energy (you left out energy) has been elaborated and deconstructed down to electrons and photons and the Laws of Thermodynamics and the Four Elementary forces... and then elaborated and deconstructed further into quarks and bosons. Now we're elaborating and deconstructing even further into String Theory or whatever better model supplants it. Ultimately we'll end up with a very elegant model that explains everything we observe in the universe and leaves us with a minimal set of irreducible questions that veer away from physics and math into pure philosophy.
The God model, on the other hand, cannot be elaborated and deconstructed, is astoundingly inelegant, raises more questions than it answers, and directs those questions toward cosmology's scientific node rather than its philosophical node. Calling this a model of the universe is a retreat into comfortable ignorance and leaves science to clean up the mess by answering a bonehead question, "Where did the god come from and what is its energy source?"
Can either matter or God or nothingness be separated from the perspectives from which experiencing allows them to come into existence?
You're overtaxing the word "perspective" by putting religion on par with science and casually tossing off the notion that science and religion are merely "different perspectives," implying that each therefore has its own claim to validity.
This model equates ignorance with scholarship, and it doesn't withstand peer review on this website.
Look at our number-lines; they extend infinitely in two directions and have a mid point that is not off center in either direction. Number lines a comprised of infinitely small points that can be approached but can never be arrived at. It seems to me that the points are in fact made of nothing. Whether we are talking about time, or dimensions of space, or the dimension of solidity to emptiness, or the dimension of inside to outside, or absolutely me to absolutely not me, or god to not god, or good to evil, or attraction to repulsion, or truth to untruth, the number-line of nonexistent points extending infinitely in two directions remains the form. What is now but a nonexistent mid point between the nonexistent future and the nonexistent past? What am I but here and now in nonexistent time and space. Try to find yourself; it can not be done because you do not exist.
* * * * NOTE FROM THE LINGUISTICS MODERATOR * * * *
You're getting hung up on the limitations of your language. It is the job of science to transcend them.
What do you call that from which nonexistent existence emerges? It depends on your perspective.
Perhaps, but it also depends on your language. Restate that question in Bantu or Hopi and see what kind of answer you get. For example, those people might turn out to be much less tolerant of discourse-stalling oxymorons like "nonexistent existence" than you are. Personally I regard them as sophomoric.
. . . . because hallucinations are something.
This is wordplay, a trick of linguistics. Let's please get back to science!
