quote <<Hoyle also seemed obsessed with how close he had come to discovering the cosmic microwave background. It was 1963, and during an astronomy conference Hoyle fell into a conversation with Robert Dicke, a physicist who was planning to search for the cosmic microwaves predicted by the big bang model. Dicke told Hoyle that he expected the microwaves to be about 20 degrees above absolute zero, which is what most theorists were predicting. Hoyle then told Dicke that in 1941 the Canadian radio astronomer Andrew McCullough had found interstellar gas radiating microwaves at three degrees, not 20. >> As we all know a CMB was found in 1965 but I was not aware that the early Big Bang theorists predicted a higher temperature for the CMB. I wonder how this discrepancy was explained by the BB theorists. Harry
