Dark matter falls into two catagories..wimps and macos.. wimps small particles that interact weakly..the use of the word weakly seeks by that to relate wimps to gravity but as far as I can see there is no offerring as to how such particles "weakly interact" and interact with "what" for that matter. One search for wimps is done in drums of cleaning fliud with cameras to record the interaction of a paticle ..such data being accumulated to get numbers and how they compare to the theories interested in a head count.
Nuetrinos could be spelt differently also .. They are candidates for wimps and dark matter and are just like my gravity rain particle..small beyond observation have mass and travel at C ..yes have mass and travel at C.. someone said it and we all thought that was impossible ..not all the energy in the Universe can propell a grain of sand at C according to the sums. so finding a nuetrino has mass and travells at c is very exciting stuff.. I say they are the tip of the gravity rain ice berg but then I would say that about anything such is my preoccupation with gravity. AND macos are big units I figure like there being more brown giants than they have expected.. I think the macos side is dead in the water as so far findings have not helped support dark matter as being found in the macos sources.
If you see dark energy as being everywhere that is the only way something as large as gallaxies can be held in place attraction from within will fail to do it..model it but there can be not other result its the same as the stick in glue example..which I hope you noticed or that will be meaningless. I think it is popular thought that dark energy pushes ..it is not just me say as such.. Dr E was looking for a cosmological constant so to explain this pushing force, he later withdrew the idea but over the last couple of years it and similar approaches to dark energy are being considered.
