The Wikipedia entry on dark matter is dense with technical terms but still quite interesting. https://en.wikipedia.org/wiki/Dark_matter  The theory is not quite as simple as "90% of the universe."  More like 90% (or 80%, Wiki says) of the parts of the universe that could be observed if you were there to observe it.

The gist: there's a bunch of gravitational behavior out there that can't be accounted for by the matter we can see through interactions with light (or the rest of the electromagnetic spectrum either). So we don't know what's holding these things together.... galaxies and other things.
