I Dark Matter vs Modified Gravity: Uncovering New Theories

[Fred Bett]

Dark Matter was never found, what Modified Gravity theories should we check now?

 

[pervect]

I wouldn't rule out dark matter just yet - it's still the most popular theory. Some alternates are TeVeS, which apparently has some problems of its own. See for instance the wiki https://en.wikipedia.org/wiki/Tensor–vector–scalar_gravity, which links to the following criticism by Seifer: https://arxiv.org/abs/gr-qc/0703060

What you think about MOG Modified Gravity theory from John Moffat?
he don't need the Dark Matter proposal that may be same like ether, non-exixting

What you think about MOG Modified Gravity theory from John Moffat?

Your link didn't work for me. (Probably better to post a link to arxiv rather than post the PDF directly)

To my understanding, John Moffat 's MOG is an example of the TeVeS theories that @pervect mentioned above.
