Fraser Cain on Nostr: Dark matter seems to be an invisible particle that only interacts with regular matter ...
Dark matter seems to be an invisible particle that only interacts with regular matter (or itself) through gravity. But in a new study, based on data gathered by Hubble, researchers think they've found evidence of interactions with regular matter beyond just gravity. They recorded the structure of a low-mass galaxy, measured the concentrations of dark matter, and then compared that to simulations where dark matter only interacts through gravity and found a discrepancy.
