What makes things more interesting, the matter we see is only smaller part of the matter of the galaxy.
Dark matter is unseen matter, which has about 10 times more mass in our own galaxy than we have matter we can see.
A quotation from Wikipedia article:
Quote:
For comparison, the Milky Way is believed to have roughly 10 times as much dark matter as ordinary matter.

For those who say it is/may be untrue: This same conclusion about dark matter you can make from various different places in the internet, including BBC site and Berkeley university.
