What does the Cosmic Microwave Background tell us about some of the currently fashionable cosmological theories?

As I understand it, the CMB corroborates the Big Bang theory. It is the energy "echo" of the explosion that formed the entire universe as we know it.

Even before the CMBR was discovered back in the 60's, cosmologists working with the Big Bang model worked out what the temperature at the instant of the BB should have been. When the cosmic microwave background radiation was discovered in the 1960's it very closely matched that prediction. Today it's widely accepted that this is the residual temperature left over from the moment of the Big Bang. For the most part, there are only infinitesimal variations in the CMBR no matter in which direction we look, further supporting a universal temperature that fills all space.

The study of the Cosmic Background radiation confirmed:
1. That there was a Big explosion and all the matter was in one single point at the beginning.
2. That the universe didn´t cool down the same way in all its points and thanks to this galaxies and planets were formed and we do exist.
3. That the Universe es 13,700 years old.
