The fact that the dark matter component of each cluster has passed through each other is a strong indication that dark matter is largely composed of WIMPS.

I bet that the photo shows no dark matter but only what an artist has drawn in to represent where they believe it to be... we can not see it so I doubt if the photo is fairdinkum if it claims to have actually photograped dark matter...
Well when it started there were machos and wimps..machos have been written off as a none event so if thgere is to be dark matter the straw that they must grasp is the wimp prospect...Wimp..weakly interacting massive particles..I think it stands for...nutrinos are a candidate... but I want them for my gravity push particles
The models I have tried to work out...with my humble math and hill billy calculus says to me that there is no way you can add material to the outside of a galaxy such as proposed by dark matter and get the unit balanced..it is a case of the more you add the more you need to add...still I could be wrong but if attraction is at play why do they see dark energy as a pushing force??? and attraction can not hold a galaxy together... one needs an external force... again opinions only but in my opinion dark matter is bulldust and any model that needs to have a hiugh percentage of stuff to be beyond our ability to observe it ...well it needs something better... I know they infer where the dark matter is..but that relies on attraction and there is no such thing as attraction...in my view...but push fixes the dark matter problem...we dont need it at all and can have a universe where what we see is what we get...
The Razor says go simple and you have to admit my ideas are simple...
