More observations of Dark matter dimension:

Four different collisions of galaxies show that the involved dark matter seems to react with the gravity in two distinct ways. One way is with an extensive gravity field and one with only a quarter of the strength.

One answer is that the Higgs boson is configured differently in each dimension like assembling the shape of a boson with "Lego blocks" so it has the same shape but different colored blocks.

Our dimension has a Higgs boson that has a weakly interactive mass but a large field and as I speculate one more Higgs boson that has zero interaction. In the dark matter dimension (in-out) there are two bosons. One it shares with our dimension with zero interaction and another it shares with the next dimension over the (out in) and so on until finally reaching the out out dimension with its unique Higgs like boson.

Our dimension is small when compared with the sum total of all the dimensions. One reason for this was the elimination of almost exactly half of its mass was eliminated in the neutralization of matter in the great matter anti matter explosions early in our (on-in) dimensional universe.

In a similar war the extreme opposite dimension of out-out may have had a similar kind of huge and opposite polarity like its version of antimatter, antispace. This explosion could have resulted in an explosion of space which explains the theory of Inflation very well.
