An [e]ffect, that we attribute to SOMETHING being there (in terms of mass) is observed.

That that "something" which causes that "effect" is called - by the people who discovered it and therefore have the right to name it - "dark matter." It may not be comprised WIMPs or WISPs, or any of the other candidate explanations, but it's there.

Ultimately, your argument is that since there is not an explanation that fits neatly into your view of the cosmos, that 'dark matter' does not exist. Fine. You're welcome to your opinion. I don't share it.

You did not understand my position.

I am advocating that since the theory does not fit the observations, we should not blindly assume that out theory is correct.....we should consider alternate explanations, other than assuming dark matter exits.

After all, the whole universe is showing us something is not right - either our theory is wrong, or there is “dark matter” we can’t see.

Gravity is one of the least understood forces, so I believe that our theories are wrong, not that we can’t see 85% of the universe.
