1924–2024: Edwin Hubble and the Evolution of Modern Cosmology
- Simone Bianchi (Istituto Nazionale di Astrofisica (INAF))
The discovery that what were once called spiral nebulae are other galaxies similar to our own, has modified our concept of Universe and marked the beginning of extragalactic astronomy, of space exploration beyond the Milky Way and of its time evolution. In this talk I will summarize facts that have stimulated and driven Hubble’s discovery 100 years ago, and which have been the immediate...
The thesis I will present concern the new idea of Large Scale in cosmology due to Hubble's discovery. I propose that the hypothesis of a larger universe was probably a cultural need born not only in astrophysics environment, but already present in the air and stimulated by the social events of that period. I will make an "investigation" of some of them, focusing mainly on the general political...
The standard belief is that the expanding universe was discovered by Edwin Hubble in 1929. Important historians of cosmology (H. Kragh, R. Smith, S. Bergia, C. O’Raifeartaigh) have recently underlined that the question is more complicated, and Hubble cannot reasonably be credited with this discovery: his measurements only provided the first experimental evidence in support of the...
