Of course, the Universe is expanding, and the proper description of that is in general relativity, but we will see that with a simple non-relativistic analysis, supplemented with a few nontrivial points, we can go

I will presentthe evidences, then review the possible candidates for dark matter, and finish describing the .CDM model.

After that, we will count degrees of freedom, in order to see what supergravity models we can have. After defining the vielbein-spin connection for
