"A dark matter halo"
Could this mass or gravitational impact be outside the expanding bubble of spacetime? If we are in a hole inside a block of swiss cheese, is there a way to determine if we are seeing the effects of the surrounding "cheese"?
Imagine our expanding universe to be inside a black hole. Could the "dark matter halo" be energy/matter dumped into our universe from an external source? Is the expansion of the universe actually our universe growing due to consuming its surroundings?
There is also the galactic rotation curve evidence. With Newtonian physics, the visible mass in galaxies should rotate faster toward the center and slower toward the edge. This is the rotation curve. We actually observe a very linear curve, where the outer stars and gases rotate at the same speed or even faster than the centers. A dark matter halo would provide the additional gravitational mass for cohesion.
