In the early 1960s, work on Brans–Dicke theory led Dicke to think about the early Universe, and with Jim Peebles he re-derived the prediction of a cosmic microwave background (having allegedly forgotten the earlier prediction of George Gamow and co-workers).
Bob's visualization of an oscillating universe stimulated the discovery of the cosmic microwave background, the most direct evidence that our universe really did expand from a dense state. A key instrument in measurements of this fossil of the Big Bang is the microwave radiometer he invented.
Nov 19, 2015 · Two Princeton professors, John Wheeler and Peebles’ mentor, Robert Dicke, decided that research on the cosmic scale should not be neglected. Since 1915, when Einstein developed the theory of general relativity to explain the behavior of large objects in space, hardly any further research had been done on gravity or the structure of the universe.
cosmic background radiation. Penzias then called Robert Dicke in Princeton and told him that he had measured ’an excess antenna temperature’ of about 3K. Dicke, together with Peter Roll and David Wilkinson visited Bell Labs to see the data and the details of the experiment. When Dicke was convinced they had a result, Penzias suggested to

In the early 1960s he and his student James Peebles independently repeated George Gamow's prediction of a cosmic background radiation, and almost immediately afterward correctly interpreted Arno Penzias's and Robert Wilson's discovery of the cosmic background radiation.

When was the cosmic microwave background discovered?
Early measurements of the cosmic background radiation showed that it peaked in the microwave (hence the name Cosmic Microwave Background). The peak wavelength was around 2 mm, and the shape of the spectrum seemed roughly consistent with that of a blackbody.
