Alternative to dark matter

[gosub]

A Breakthrough Some Cosmologists Thought Would Never Come

A new theory of the universe’s structure might offer the most plausible alternative yet to dark matter.

Not much of an alternative really...



The article is pretty reasonable once you get past the breathless bit at the top.

This bit was interesting though...

“For 15 years we’ve just been dead in the water,” says Stacy McGaugh, an astronomer at Case Western Reserve University and a longtime advocate for modified-gravity theories

...after spending the last 15 years saying exactly the opposite to as many gullible journalists as he could find.

I don't believe in Dark Matter / Dark Energy as a conclusive interpretation/explanation.

I like to think Neutrinos have something to do with it.

Neither do scientists. That's partly why they gave those things such enigmatic names. They are observable phenomena that represent gaps in our current understanding of physical cosmology.

I like to think Neutrinos have something to do with it.

Physicists have already considered this, and it turns out that neutrinos are too hot to be dark matter.

Also on MOND, well outside my ken but seems to be based a a somewhat different theory to the article linked in the OP: Dark matter: Our review suggests it's time to ditch it in favor of a new theory of gravity

It's not a theory, it's just curve fitting. And it still hasn't solved the problems that lead to experts rejecting it.

New 3D cosmic map reveals 1 million previously hidden galaxies

Astronomers have created the largest ever 3D map of 1 million distant galaxies otherwise obscured by the Milky Way's dwarf galaxy neighbors, the Magellanic Clouds.
