>Dark matterEssentially, we observe stronger gravitational effects (gravitational lensing, galaxies rotating faster, etc.) than we should see given the predictions of general relativity. There seems to be too much gravitational interaction given the amount of baryonic matter we've observed. At the same time, we also see galaxies that behave in a manner consistent with the amount of baryonic matter they contain.
The explanation for this extra gravity is that there are weakly interacting massive particles (WIMPs) that are producing this gravitational interaction. Think of neutrinos, except for much more massive. This explanation is fairly simple, and fits with our observations. There have been attempts to create a new theory to replace GR, but none of them work as well as the WIMP theory.
>Dark energySpace is expanding. All points in space are moving away from every other point. This expansion seems extremely consistent, so the theory is that space itself has a homogenous level of repulsive energy. We've already confirmed a vacuum to have a low level of energy. I'm too tired to type anything else, I'm sure you get the point.
