Case for axion origin of dark matter gains traction:
The existence of dark matter has been confirmed by several independent observations, but its true identity remains a mystery. According to this study, axion velocity provides a key insight into the dark matter puzzle. Previous research efforts have successfully accounted for the abundance of dark matter in the universe; however certain factors, such as the underproduction of axions with stronger ordinary matter interactions, remained unexplored.
By assigning a nonzero initial velocity to the axion field, the team discovered a mechanism—termed kinetic misalignment—producing far more axions in the early universe than conventional mechanisms. The motion, generated by breaking of the axion shift symmetry, significantly modifies the conventional computation of the axion dark matter abundance. Additionally, these dynamics allow axion dark matter to react more strongly with ordinary matter, exceeding the prediction of the conventional misalignment mechanism.
"The extensive literature on the axion was built upon the assumption that the axion field is initially static in the early universe," stated Keisuke Harigaya of the Institute for Advanced Study. "Instead, we discovered that the axion field may be initially dynamic as a consequence of theories of quantum gravity with axions."

And what do you know. One more ignorant fucking basement dweller who thinks he's smarter that all astrophysisists.
The Internet really is the black hole that sucks all the losers of society.

You don't need to be a physicist to see them claiming shit is true that they can't prove. That ain't science, that's religion.
My rights don't end where your fear begins.

All you have to do is show us the PROOF that all these physicists have.
Do that and you will have converts. But you can't, because there is NO proof: DM is a kludge physicists came up with SOLELY for the purpose of saving GR.
Instead of acknowledging GR has another problem and needs to be resolved some other way, they waved their hands and came up with an ever changing DM.
Waving hands is NOT proof: if you think we're just basement dwellers who are stupid, SHOW US THE PROOF, not hand waving, ever changing shit made up to fill a gap. But you and all your GR religion following physicists have no proof to show because there is none.
So, basement dwellers one, GR religion following physicists zero.
