Abstract: If supersymmetry is realized in nature, even at some very high
energy scales, it has important cosmological consequences.
A generic prediction of supersymmetry is the flat directions
in the potential, along which a scalar condensate can form at
the end of inflation. This condensate is generically unstable;
its evolution and its fragmentation into Q-balls can generate
the baryon asymmetry, dark matter, and the gravity waves that
can be observed by upcoming detectors.
