I have been researching online, but there are many things I am still unsure of because its hard to find the answers to specific questions.
1.) I know how scientists observe dark matter. They can view its gravitational effects. I want to know exactly how it is distributed throughout the universe though. I've heard that it clumps together on the edges of galaxies, but is this true for all galaxies? Can clumps of dark matter be seen out in the vacuum with no proximity to normal matter at all, or are they always attached to "normal" matter?
2.) Does dark matter move with "normal" matter or does it generally stay stationary at one point in the vacuum?
3.) Does it appear to be the same kind of dark matter throughout the entire universe, or do some clumps of the same size appear to have larger gravitational effects than others?
4.) How do scientists observe the effects of dark energy other than seeing that the expansion of the universe is accelerating?
