The scale factor of space is inversely proportional to the distance from the center of a galaxy. Space with a low scale factor produces stronger gravitational attraction for the same mass.

Phenomena explained: It is observed that gravitational lensing is far more powerful than the observable baryonic matter of the globular clusters which cause the lensing would lead us to expect. It is observed that when galaxies collide, the original galactic cores continue to determine the gravitational lensing effects, regardless of the existence and location of new concentrations of matter due to interactions between the galaxies. |
Gravitational lensing is far more powerful than conventional cosmology leads us to expect, because the scale factor of the space surrounding globular clusters is much smaller than 1. As discussed in the lemma galactic rotation, this results in gravity being more powerful.
The relationship between the original galactic cores of colliding galaxies and their gravitational lensing effects is consistent with our hypothesis, presuming that the rate of space diffusion is slow. The collision does not last long enough for substantial diffusion of rich space (i.e., a larger scale factor) into poor space.

Credibility: The explanations of mainstream science involve dark matter, which has never been isolated and for which we have no explanation as to how it can exist or what it is. That makes such explanations score at least as a complex gap. Our hypothesis requires only that the expansion of space can vary locally, making it a complex hypothesis, which is at least three notches better on the Occam Scale. However, we have not demonstrated that this explanation is the only possible explanation for space which is compatible with this assertion. There may be other explanations which are more credible, but unimagined and perhaps unimaginable. Therefore this explanation is tentatively credible. |
