Is it safe to say that no one is questioning the Theory of Relativity, QM or basic observational physics in our space/time?

The only question seems to be is if there is some hypothetical being outside of space/time (reality as we know it) could other rules apply to that being? Certainly! Anything is possible in our imaginations! Heck we even invented God : )

As that statement stands, it is merely a totally unsupported (pre)supposition. What "we" ever "invented" God? Let's see your data!

And it seems to me not everything that we can imagine becomes "possible" simply because we can imagine it. Do unicorns really exist? If they do, it seems they exist in a sense that is not physically realizable. Just like most "second realities." They can be "imagined": But if they don't "map to Reality," they cannot exist as real entities.

No, I wouldn't say it's necessarily "safe" to say any of those things. The fact is, we really don't know; but these theories seem to be the most promising ways we have right now to engage issues of perennial puzzlement to human kind — unless or until something "better" comes along.

The point being that Truth is by its nature a quest, never a final possession. And that we stand on the shoulders of giants.

God is not a hypothesis. He lives. His Name is I AM. I've known Him for about a half century and counting.

We have mentioned a few more recent theories (e.g. Vafa, Wesson, Tegmark, Fineman) which build on Special and General Relativity. As far as I can see, no one has been advocating these theories but rather using them as examples. More specifically, these are theories which can be put to the test, e.g. prediction, observation, falsifiability.

Of course beyond these theories are things which are unknown and unknowable. Among them are the possible existence of massless particles or waves which have no measurable direct or indirect affects. Likewise, we cannot know the precise number and types of dimensions (temporal/spatial, compactified/expanded.)
