What's this?

Not quite

Dark MATTER is what keeps galaxies together because there is not enough normal matter to do so. I think we pretty much know dark matter exists because of gravitational lensing.

Dark ENERGY is what physicists blame on the ever expanding universe. We don't know much about dark energy.
