How Much Dark Matter Is in Our Milky Way?

Our milky way has a higher density of regular matter than the rest of the universe, or other parts of the universe. On average, galaxies have about 80 % dark matter, and our galaxy is 95%. You can tell when te galaxy is overwhelmingly dark mater because its stars are moving super nuper fast compared to how bright they are. And so we can see these faint dwarf galaxies, for example, just have a handful of stars, but there's not nearly enough gravity to hold them in place.
