AbstractSince Edwin Hubble introduced his famous tuning fork diagram more than 70 years ago, spiral galaxies and early-type galaxies (ETGs) have been regarded as two distinct families. The spirals are characterized by the presence of disks of stars and gas in rapid rotation, while the early-types are gas poor and described as spheroidal systems, with less rotation and often non-axisymmetric shapes. The separation is physically relevant as it implies a distinct path of formation for the two classes of objects. I will give an overview of recent findings, from independent teams, that motivated a radical revision to Hubble's classic view of ETGs. These results imply a much closer link between spiral galaxies and ETGs than generally assumed.

The Universe

During the 1930s when a relativistic, expanding, homogeneous model of the universe lead to an age for the universe embarrassingly less than the geological age of the earth, the astronomer Edwin Hubble, influenced by philosophical values, persisted in his support for a theory in conflict with observation and prediction. Notwithstanding well attested and unrefutable evidence of geological time, and various astronomical observations as well, the theory of a homogeneous, expanding universe of general relativity proved, in practice, not falsifiable.

This article considers the role of physics in transforming cosmology into a research field which relies heavily on fundamental physical knowledge. It begins with an overview of astrophysics and the state of physical cosmology prior to the introduction of relativity, followed by a discussion of Albert Einstein’s application of his new theory of gravitation to cosmology. It then examines the development of a theory about the possibility of an expanding universe, citing the work of such scientists as Edwin Hubble, Alexander Friedmann, Georges Lemaître, and George Gamow; the emergence of the field of nuclear archaeology to account for the origins of the early universe; and the controversy sparked by the steady-state theory. It also describes the discovery of a cosmic microwave background of the kind that Alpher and Herman had predicted in 1948 before concluding with a review of modern cosmological hypotheses such as the idea of ‘multiverse’.
