For the record, MOND and hdm. Likely a sterile neutrino. 11-13 TeV.
Yeah, I know. I don’t strike you as a cosmology / astrophysics guy. I’m a neophyte. Love the stuff.
In short, lambda CDM is a bust and mentally lazy. In fact, its a lot like religion. Some guy came up with a fudge factor “constant” to fix his shit because he admitted he didn’t know shit. Fast forward 60 years and the science equivalent of baseball nerds are performing mental gymnastics to make this unknown work.
Enter Milgrom and Modified Newtonian Dynamics. A lot of the holes in the lambda CDM framework need (an) amazing particle(s) to fill in the blanks and make things work. As well, observationally, the universe has features that fail with Dark Matter. Enter the KBC void amongst other recent disoveries.
A vast underdensity in the local universe, where there is a dearth of detectable baryonic matter on a size that refutes many models involving cold dark matter. This doesn’t even include vast superstructures visible that also are impossible among many models.
On smaller scales, lambda CDM models also fail when explaining the absence of dwarf satellites. There should be thousands in the Milky Way galaxy’s dark matter halo. There aren’t.
When viewed via MOND, you start to see tidal disruptions and dwarf galaxies for what they are; the same thing. When you look at the Local Group’s orientation, the orientation of its constituent galaxies and the orientations of the streams, you see interactions free from Dark Matter theory.
Just this basic picture, tells me that Andromeda and the Milky Way have previously interacted. M33 may possibly be a portion of Andromeda or the Milky Way from that ancient pass. I’ve seen other articles that plot both the rotational axis of the dwarfs and the linear alignment of the major and minor galaxies. Its amazing to see them line up.
Anyway, I’ve said that dark matter is hooey for about a decade now. I just wanted it in writing. 😀
Saw it on the Internet. Must be true.
