Phenomenology of the Invisible Universe
Cosmology is operating now on a well established and tightly constraining
empirical basis. The relativistic LambdaCDM hot big bang theory is consistent
with all the present tests; it has become the benchmark. But the many open
issues in this subject make it reasonable to expect that a more accurate
cosmology will have more interesting physics in the invisible sector of the
universe, and maybe also in the visible part.Comment: Proceedings of 'Invisible Universe International Conference', Paris,

Discovery of the Hot Big Bang: What happened in 1948
The idea that the universe is filled with the thermal radiation now termed
the Cosmic Microwave Background was first discussed in eleven publications in
the year 1948. These papers offer a detailed example of the process of
development of a new and now very productive line of research, and of the
confusion that can attend new ideas. The confusion in this case left a common
misunderstanding of the considerations that motivated the idea of the sea of
radiation.Comment: A 24-page preprint; version 2 has additions, revisions and
