Yes you can't image dark matter. The blue area has been mapped to define the region of gravitational lensing. The pink area is the X-ray image showing the collision of matter (gas) from each cluster.

If dark matter doesn't exist then the blue and pink areas should be superimposed.

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

You couldn't pick a worse candidate for a push particle.

Neutrinos are the byproducts for the fusion of hydrogen nuclei. Instead of acting as a neutrino shield, the Sun becomes a source of neutrinos.Why is it then Mercury is not pushed out of it's orbit? The answer is that neutrinos do not readily interact with matter. That is a scientific fact.

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...

So you keep on telling us. Why don't provide us with a model that shows how push gravity preserves the shape of a spiral galaxy?

I have even a better idea. I challenge you explain how push gravity can cause Type II supernovae. The current mechanism is very easily explained as an elegant combination of nucleur physics and gravity as an attractive force.
