(at least so many dimensions, etc.), for the
"SPACE" / "TIME" in which they are presumed to have existed? Would the universe continue to be definable within that frame? Would it have a shape within that frame, and boundaries?
I'm not sure what you mean by "Would the universe continue to be definable within that frame?" I just can tell what you intend by the question.
But frames of reference are human inventions and thus we might define the boundaries of our frame of reference as being those of us on the planet earth ... as we observe other objects moving at different speeds with different acceleration in the presence of different gravitational fields.
So the boundary condition is what we define ... it is not a physical boundary. HTH.
