A likelier explanation is that gravity has a multiplicative / lensatic effect such that observed masses in proximity would actually have a higher gravitational force on a remote mass than the sum of their individual forces. Total hypothesis

This seems to be a big step forward. It’ll be interesting to see where the science community goes from here.

Will they embrace this research and dig into it further?

Or ignore it completely?

From the author themselves

The possibility of a second solution other than dark matter sounds great to me. Just because we know mass warps space, we don't know it's the only thing that does. We should have called dark matter "imaginary matter" because it's a solution to an equation that we can't solve using what's known. Interesting to wonder how we will have misnamed it in retrospect.

Dark matter is called "Dark" because it doesn't seem to interact with EM. It describes it fine and isn't wrong because you don't like the the name.

This is a really poor reply.

It doesn’t answer my question of whether the exercise will be embraced or just outright ignored by the scientific community.
