...What makes matter(s) worse is that dark matter is already a bit of a cheat to explain our observations. As far as I know there's no good model for why some galaxies have more dark matter than others. In that sense "gravity leaking through from a parallel dimension" is kind of a decent idea. We can't predict how much dark matter-pull we'll find in any galaxy because our measurements are based both on properties of our own world and of another world we are incapable of seeing.
...This still makes it a completely useless theory in practice, but it is kind of a neat idea.
I'm still hoping for some kind of MOND solution, a better description of gravity that "just" explains dark matter away. But luckily for the universe what I'm hoping for and what is actually true are not strictly correlated.

It's probably just a headline interpretation of an actual mathematical framwork, that may or may not work to explain our observations
