>>12241085thanks for the response. I had not considered the fact that dark matter wouldn't have elctromagnetic forces so I couldn't form a tight ball. However, I'm still not convinced it would be as difficult to detect as people claim. If 84% of our galaxy is truly dark matter, then I would predict the following effects:
1. Dark matter would cause random wobbles of other bodies
When space dust collides the orbit stabilizes. Assuming that dark matter could pass right though the center of a star without slowing down, then the path of the dark matter would become chaotic. Assuming that since the majority of the galaxy is made up of the stuff, a a star completing a single orbit around the galaxy would run into a ton of it. Therefore, the collisions would be happening enough that you would predict waves of chaotic dark matter to be randomly produced by every single star. The waves would certainly become concentrated enough at times to cause detectable wobbles of random objects. looking at it another way, consider it to be like the currents of air. Concentrated clumps of stars would produce a low pressure due to gravity which the dark matter would naturally flow to, therefore dark matter currents like air would be produced.
2. Unexplained rapid expansion of black holes:
Dark matter should not be able to escape a black hole, since spacetime is warped. Therefore, you would assume they would be gobbling up dark matter like skittles (especially considering the erratic orbits suggest by my first point) so they should grow faster then predicted at times.
3. Increasing mass of solar systems
Assuming that dark matter is evenly spaced out to prevent clumps or any sort of gravitational lensing within our galaxy, then it wouldn't stay that way for long. There are so many stars orbiting our galaxy, all the dark matter would be 'captured'. Within a galactic year of our on sun, you would predict that enough dark matter would be caught of effect the orbit of outer bodies
