Abstract. We analyse the history of modern cosmology based on the redshift phenomenon
and on the cosmic background radiation (CBR). We show the models of different authors
for the interpretation of the redshift and how the tired light models predicted the correct
value of 2.7 K temperature previous to Gamow and collaborators.
Key words: Cosmology,...

We present a new approach to resolve an age of the universe of 13.794 billion years using measures of the fine structure constant, the radiation constant, the temperature of the cosmic microwave background and the defined values for the Boltzmann constant and the speed of light. We also resolve a diameter associated with the physical universe equal...

Charles Édouard Guillaume (1861–1938) was a Swiss physicist who received the 1920 Nobel Prize in physics for his precision measurements and discovery of anomalies in nickel steel alloys. In this work, we present a complete and commented translation of his remarkable article of 1896 on the temperature of interstellar space. The importance of this work is that it is the oldest estimate known to us of the temperature acquired by a black body, which is in interstellar space far from other stars. This temperature was presumed to be due to an equilibrium state in which the radiation received by this body from the stars around it would be equal to the radiation emitted by the body. He arrived at a temperature of 5.6 K, regarding this figure as an upper limit on the effect he was seeking to estimate. In 1926, Arthur Eddington (1882–1944) arrived at a temperature of 3.18 K, utilizing essentially the same procedure but with better data.
