Question

Why do we expect wimps to be distributed throughout galactic halos, rather than settled into the galaxy's disk?

Answer 1

The answer is that "since they do not interact with the electromagnetic force, they do not feel friction or drag and hence do not contract with the rest of the protogalactic cloud." WIMPs (Weakly-Interacting Massive Particles) are hypothetically constituted to dark matter. It is in their nature to be less interactive, so they are scattered throughout galactic halos and not focused into the galaxy's disk.

Answer 2

Answer:

Since they do not combine among the electromagnetic force, they do not sense resistance or pull and hence do not engage with the bottom of the protogalactic cloud.

Explanation:

WIMPs (Weakly-Interacting Massive Particles) are theoretically established to obscure material. It is in their quality to be limited interactive, so they are dispersed everywhere galactic radiance and unconcentrated within specific galaxy's plate.
