「暗黒物質」について；
Vera Rubin found that galaxies don’t quite rotate the way they were predicted, and that lent support to the theory that some other force was at work, namely dark matter.Dark matter, which hasn’t been directly observed, makes up 27% of the universe – as opposed to 5% of the universe being normal observable matter. Scientists better understand what dark matter is not rather than what it is.
