Martin,
Very much so. Finding those both inside and outside the bubble is a search.
As for space, consider that the frame with the longest ruler and fastest clock would be closest the equilibrium of the vacuum, the unmoving void of absolute zero.
So the conceptual parameters of space are infinity and equilibrium, zero to infinity.
The energy radiates toward infinity, while the structure coalesces toward equilibrium.
Anything actually falling into black holes is shot out the poles as quasars, which are like giant lasers and lasers are synchronized light waves.
One of the problems in cosmology is dark matter. That there is far more gravitational effect, than mass to explain it, but what if it's the other way around? That the properties we associate with mass, as tactile, object oriented creatures, are intermediate effects of this centripetal dynamic of synchronization, as the basis of structure coalescing, interacting with the elemental energy expanding?
One very obvious problem with current cosmology is that if intergalactic space were to expand, why doesn't the speed of the light crossing it increase proportionally, in order to remain constant?
Instead, two metrics are being derived from the speed and spectrum of the same light and given it is an expanding space and not tired light theory, the speed is still being used as the explicit denominator.
One way light does redshift over distance is as multi spectrum packets, as the higher frequencies dissipate faster. Yet that would mean we are sampling a wave front, not detecting individual photons traveling billions of lightyears. So the quantification of light would be an artifact of its detection and measurement....
Basically the outward curvature measured in the light, between galaxies, is balanced by the inward curvature within them, based on gravity. The Cosmological Constant. Omega =1.
As for dark energy, if this outward curvature compounds on itself, that would explain what amounts to a parabolic curve in its rate.
I am in no ways a cosmologist, or even scientist, just a lifetime of trying to make sense of all the moving parts.
