Description
Even though the Cosmic Microwave Background (CMB) is a photograph of the Universe when it was about 400000 years old and had a temperature of about 0.3eV, it contains information about a much earlier phase of the Universe, most notably inflation.
In my talk I shall describe the amplified quantum fluctuations which we observe in the CMB. I shall discuss what we already know and what we might learn from future observations. I also argue why we are convinced that a mechanism similar to inflation is at the origin of the observed spectrum of fluctuation.
