    I believe that this is not the answer to dark matter, but rather “We knew how much of the universe was made up of baryonic (normal) matter, and we guessed it was intergalactic gas, and now we have measured that.”

      Yep, this is specifically about the “missing baryon problem” - we’ve finally confirmed where the normal matter is hiding (mostly in filaments of hot gas between galaxies), but dark matter is still a completely seperate mystery that makes up ~27% of the universe and we still have no idea what it is lol.
