Sure, as long as it's a reality within our own perceptual relativity frame of reference. The further our imaginary reality is from our own PRIF, the less likely that it could reflect the concrete experiences that would occur there if that reality were manifested physically. > What can be shown is that each of two universal machines put in front > of each other can develop a true and incommunicable belief in a > reality.

I think it depends on what the machines actually are physically as to what they will be able to believe or develop. If you execute the machine in silicon, you're going to have a polite glass sculpture of belief, not a fierce, viscerally passionate belief. The math alone can create a correspondence as-if it were true, but only the physics can create the conditions of true through experience in spite of logic, which is what gives the believer not only separation but something of a trump-card privilege over the believed. In a contest of math v physics, I think the physical can generate novelties in advance of math, so that the arithmetic is an analytical afterthought. Physics cannot be anticipated from the math alone, it can only be reverse engineered from factual physical observations. Math can of course be used to build on physics as well (nuclear fission, etc) but it still requires a priori indexes of atomic behaviors which are independent from pure arithmetic.
