I was glad to find this post because I am working on a theory that is based on radiation pressure from another contiguous universe (includes multiverse theory) as a possible explanation for the acceleration of the universe as evidenced by the examination of SN1997ff.  I am currently trying to grasp the mathematics associated with the topology/morphology/manifold structure or mathematical modeling of the Minkowski space from the point mass expansion at time = 0 to the present.

Assuming we have multiverses' interacting with the boundaries of our universe, the radiation pressure from one or more of these universes (that are external to our own) can couple or interact at the boundary of expansion.  This interaction would behave as a curvilinear pressure wave on the Minkowski space boundary of our universe.

In simplest terms, from the basic physics of hydrodynamics where A1V1 = A2V2 we see that (A1V1)/A2 = V2.  Therefore radiation pressure that is external to our universe but constricting the area of expansion will cause an acceleration as the area of first expansion is constrained by outside forces.

As the curvature of the external radiation pressure wave 'eases' off, as the expansion in our universe continues, there should be an eventual slowing down of our universes' acceleration as the conflicting forces 'decompress'.

Observations could be made to determine the approximate curvature of the impending radiation pressure which could give rise to a measurement of the size/curvature of the universe that is impinging on and external to our own universe thereby giving rise to the corresponding acceleration of our universe as it enters its dark-energy-dominated era roughly 5 billion years ago.

Work in progress.

Hi, I was fascinated to read this. I came up with roughly the same idea while expanding on the cosmological points related to a theory of quantum gravity I've been developing. In my notion, gravitational fields are formed by ephemeral, tunneling electrons; these electrons appear for roughly one unit of the Planck time in the gravitational field of the object to which they belong, move through space in tandem with the object's rotation, and exchange W particles with protons (if they're within the electroweak range), or absorb/emit a photon, or exchange a neutral current with a neutrino (leading to an oscillation, or change in flavour), depending on the sort of particle they're closest to when tunneling to a new location. If this is the truth, then it would account for the reflective capacity, via general relativity, of gravitating bodies (since we know, of course, that electrons reflect light). Extrapolated to galaxy clusters, as in the vase of 'dark' energy, we could surmise that, since the Big Bang, huge amounts of radiation (photons) have been accumulating between galaxy clusters and the radiation pressure generated has led to the accelerating expansion of the universe. If you're interested, I have an article on my Medium profile detailing this idea:https://medium.com/data-driven-fiction/why-dark-energy-is-probably-radiation-pressure-9bffeb20aec1

How does that form a gravitational field?

If this is the truth, then it would account for the reflective capacity, via general relativity, of gravitating bodies (since we know, of course, that electrons reflect light).

Where does GR talk about reflective capacity?  Dark matter does not interact with photons but does have a gravitation field, how does that fit into your idea?

Extrapolated to galaxy clusters, as in the vase of 'dark' energy, we could surmise that, since the Big Bang, huge amounts of radiation (photons) have been accumulating between galaxy clusters and the radiation pressure generated has led to the accelerating expansion of the universe.

Wouldn't this radiation be easily measured on Earth?
