There are galaxies with no dark matter and Mond will not explain that.

@sonhouse saidHow do you know that?

@metal-brain saidDarling, these days even your Magic Pixie Dream Girl Hossenfelder has rejected MOND in all its various fantabulations. Let go of your obsession, with both of them.
@sonhouse
So does that mean you reject Modified Newtonian Dynamics? Yes or no?
@shallow-blue saidThe problem with dark matter (aside that there is no evidence it exists) is that it does not explain the rotation curve of galaxies. Go ahead and theorize any amount of dark matter you want, it will not explain why the outermost stars in the galaxy go so much faster than those nearer to the center of the galaxy. And I already saw that video from Hossenfelder. She does NOT really reject MoND. She said more research has to be done to know for sure.

@sonhouse saidYou have not explained the rotation curves of galaxies. Dark matter cannot explain that in any abundance. The inner stars in a galaxy are supposed to do a full rotation around the center much faster than the outer stars. They don't.
@Metal-Brain
Both theoretical and astronomical evidence. Without dark matter galaxies would be very different, probably a lot smaller because of lack of mass producing enough gravitational attraction to get large galaxies formed. And they know the mass is there because of gravitational lensing showing the presence of large masses much more than the obvious measurable masses ...[text shortened]... ose whatever fringe site you want but that doesn't mean we listen or give a rats ass what you think.
@sonhouse saidWhat does gravitational lensing have to do with it? What "stuff" are you talking about? I have no idea what you are talking about. Gravitational lensing is how you detect black holes.
@Metal-Brain
You keep harping on MOND and there are updates to that hypothesis but it still has big problems, one being it cannot explain gravitational lensing which is why we can figure out where the stuff is. MOND ONLY tries to explain the speed of stars around the fringe of a galaxy and cannot fit it into gravitational lensing.
@sonhouse saidJust admit you don't know.
@Metal-Brain
Figure it out for yourself. You don't want to learn stuff you just want to tear up anyone else saying anything about science. I don't have time for your bullshyte.
