Michael,
My experience with using that part of the mind is to simply move back and take a larger view, as opposed to the normal thinking instinct to move in closer and study the details. If you really examined this sense of epiphany, as it occurs, it's like the pieces of a puzzle arranging themselves. So what you are mentally doing is simply giving them the space to work, as opposed to trying to force them together by concentrating. The mind is a very dynamic and organic process, which our sense of immediate consciousness is a particular component. Almost like a lookout on a large ship. Designed more for detecting immediate dangers and reacting to them, or opportunities and acting on them, then serious cogitation.
One point which occurred to me many years ago, regarding the rubber sheet analogy of gravity, is that a cosmological constant means the sheet is only flat when it is completely undisturbed. So when you create pressure on one point, it will "balloon" out over the rest of the sheet to match that pressure. So say if galaxies act as gravity wells/pressure points, the flat space/sheet will balloon out between the empty space galaxies, thus balancing the effect of gravity. This "expansion" of the space between galaxies doesn't mean the overall universe is expanding, only that gravity is being equalized. Currently it seems cosmology forgets galaxies are not just inert points of reference, but contractions of space and neutralize the expansion.
One idea about the nature of gravity that has received some positive response from other amateurs is that since releasing energy from mass creates pressure, logically having energy condense into mass would correspondingly create a vacuum. If E=mc2, then M=e/c2. They can't find any dark matter halos around galaxies, but there are large clouds of radiation, cosmic rays, interstellar gases, etc. So what if gravity is not so much a property of mass, but an effect of energy fusing into mass?
So then you have the expansion of radiation and the gravitational condensation of mass as two sides of the same cycle. The issue of radiation being that while it is absorbed and therefore measured at points, it expands when released into space, rather than traveling through space as a point particle. That way, redshift doesn't have to be explained by recession of the source.
In my digital vs analog contest entry, I used the analogy of a dripping faucet as a possible explanation. In that for local sources, the light is streaming in like running water, but the further way, the more the quantity is reduced, like a faucet being tightened. Eventually the stream is reduced to a drip, but since drips are the same size, the time between each drip grows longer. So if our telescopes are viewing galaxies billions of lightyears away, the light is coming in as single photons. Since the size of a photon, the amount required to trip the electron, stays the same, the wave properties of this light are being stretched/redshifted, as it takes longer for each photon to accumulate. There are other possible explanations as well, such as Christov's Wave packet experiments.
Since space is treated as a measure, it is much easier to describe the contraction of mass in terms of points of measurement, then it is the expansion of radiation, when the actual expansion is better explained in wave, rather than point terms.
As for why physics spends to much effort building on century old models without reviewing their foundational assumptions, that's just a matter of the top down structure constricting the options of the bottom up initiates. Politics.
