Hey all, especially spacetiger, I have a question about inflationary theory for you. Its my understanding that the Period of Inflation proposed to have occured during the first second of the BigBang, was introduced to give a suitable answer to the Horizon Problem. The Horizon problem says that the thermal equillibrium we observe, as in the CMB, could not of been achieved in the early Universe since space expanded faster than C. My question is: What evidence is there to support a Period of Inflation? Is the notion merely theoretical, or is there observable grounds for this theory? Thanks.
