There is no ‘dark matter’. There is just matter.
But we know that there are more dimensions than just the four we can immediately observe so it makes sense that matter that we can observe in four dimensions also has properties that are expressed in dimensions we can’t observe.
I propose that dark matter isn’t separate from the matter we can see but that it is really just the extradimensional aspects of the matter we can see.
Well, there’s anti-matter, but that’s not “dark matter”.
“But we know that there are more dimensions than just the four we can immediately observe”
Actually, we don’t know that. That is a hypothesis used, because that is the only way the math works in their efforts to come up with a unified theory. There are zero repeatable experiments that demonstrate extra dimensions. It is purely a chalkboard exercise.
I believe we are at the end of a chain of cascading errors.
Physics 100 years from now will laugh at this era.
Or maybe it’s because we don’t understand the effects of ‘accumulated gravity on an extremely large scale’ and have ignored the concept of the effects from a vortex on that same scale.
Tornadoes carry and ‘spin’ round their center, a huge mass of objects. The wind itself has very little mass. Those objects , from trucks to dirt, should go spinning away from the ‘vortex’ due to centrifugal force.
Still, your theory should not be counted out. No one knows the real answer, yet.
“But we know that there are more dimensions than just the four we can immediately observe...”
Why do you think we “know” that?
