At first I thought that the expansion might be an illusion caused by space-time curvature. Then I discovered they are the same thing.
A study of the distribution of the irregularities in the cosmic background radiation is affirmed the idea that space is finite, looping and expanding.
"Space expanding" = "ALL distances increasing more or decreasing less than they would otherwise"
Curvature caused by gravity is in the opposite direction from the curvature which causes the expansion, which is why it is sometimes called anti-gravity. Anti-gravity gets stronger as the distance increases while gravity gets weaker, so the areas where the mass-density is lower than 0.3 H-atoms per something (can't remember) will expand at an accelerating rate, while higher density areas will eventually collapse into black holes. (Like the super-massive black holes we have detected at the centers of many galaxies.)
Since a photon cannot keep itself together by gravity, it stretches as the space it occupies stretches. This has been found to be the cause of the red-shift of light from distant galaxies.
Two very well-synchronized clocks were taken, one put into a high-flying aeroplane and the other was kept on the surface. When the aeroplane returned, the clocks were out of synchronization by a much larger amount than they would normally be, and the difference matched very closely the difference expected from time dilation caused by decreased space-time curvature at high altitudes.
Like all the important experiments, I am certain that it has been done in many parts of the world, by various different groups, before it was accepted as scientific fact. Physics tends to be studied rigorously like this, due to it following the same physical laws everywhere and sometimes yielding unexpected results. So everybody can test it and find it to be accurate. Otherwise it would not be a "hard" science.
Any theory which makes measurable predictions which can reliably be tested by anyone is an acceptable theory.
This is why I prefer modern physics over your ideas, Sean. My ire is neither dogmatic nor personal.
