  Physical cosmology - Wikipedia, the free encyclopedia
Physical cosmology, as a branch of astrophysics, is the study of the large-scale structure of the universe and is concerned with fundamental questions about its formation and evolution.
Physical cosmology, as it is now understood, began with the twentieth century development of Albert Einstein's theory of general relativity and better astronomical observations of extremely distant objects.
Cosmology is unusual in physics for drawing heavily on the work of particle physicists' experiments, and research into phenomenology and even string theory; from astrophysicists; from general relativity research; and from plasma physics.

 Theoretical Astrophysics and Cosmology
The University of Chicago is a leader in interdisciplinary research in theoretical astrophysics and cosmology, including connections to particle physics, general relativity, and computational physics.
We also have close ties to the Fermilab Theoretical Astrophysics Group, which focuses on both early- and late-universe cosmology, and the ASCI Flash Center at Chicago, which carries out numerical studies of astrophysical thermonuclear flashes.
On a parallel track, I am studying the cosmology of theories with large extra spatial dimensions, in which the particles and fields of the Standard Model are confined to a brane embedded in a higher-dimensional geometry.

Cosmology as a science began in this century with the development by Einstein of his theory of gravity, or General Relativity, as it is sometimes called.
On the theoretical front, there was the realisation that current particle physics theories had implications for cosmology and that cosmology might be the only testing ground for those theories.
This union of gravity, quantum mechanics and thermodynamics is one of the greatest surprises in theoretical physics in the 20th century.

 What is Theoretical Physical Cosmology?
Theoretical cosmologists study the evolution and composition of the universe as a system, constructing theories and confronting them with experiments and observations.
Many of the quantities of interest are average properties; consequently, theoretical cosmology deals to a large extent with statistical predictions and measurements.
High redshift supernovae searches are being pursued by the supernova cosmology project and the high-z supernova search (the latter is the source of the figure at left).

Current topics of research include inflationary cosmology, the origin of density perturbations, topological defects (monopoles, strings, walls, textures), cosmological phase transitions (electroweak, QCD, GUT), baryogenesis, particle dark matter and its detection, primordial nucleosynthesis, the evolution of structure in the Universe, the origin of CBR anisotropies, gravitational waves, and the origin of highest energy cosmic rays.
The Theoretical Cosmology group works closely with the Theoretical Astrophysics group at Fermilab which is led by Kolb and whose faculty members are S. Dodelson, J. Frieman, E.W. Kolb, A. Stebbins, and M.S. Turner.
Frieman's primary research is in cosmology, especially the formation of large-scale structure and the interplay between cosmology, particle physics, and astrophysics.

 Cosmology: Methodological Debates in the 1930s and 1940s
The year in cosmology ended almost as confused as it had begun, with one exception: Milne had gotten much clearer about his philosophical views, and was applying them to an exhaustive presentation of his cosmology, theory and philosophy.
Just as some adherents of the ‘empirical’ school tend to regard cosmology as a testing ground for their extrapolations and as a legitimate playground for the geometers, so some adherents of the deductive approach appear to regard cosmology as a purely logical subject.
Cosmology is a borderline case: since observations of cosmological significance are so rare and hard-won—Hubble's observation of the red shift was one of the first solid ones—it is very difficult, not to mention brave, to tie one's cosmological theory to Popper's falsificationist principle as a guarantee of scientific acceptability.

 Cosmology: Big Bang Theory
We can see remnants of this hot dense matter as the now very cold cosmic microwave background radiation which still pervades the universe and is visible to microwave detectors as a uniform glow across the entire sky.
This fact strongly supports the notion that the gas which emitted this radiation long ago was very uniformly distributed.
These two ideas form the entire theoretical basis for Big Bang cosmology and lead to very specific predictions for observable properties of the universe.

My other talk was at a joint double session on the past, present, and future of cosmology, co-sponsored by the Division of Astrophysics and the Forum for the History of Physics.
Six talks naturally needed to be given: one each on the past/present/future of observational/theoretical cosmology, and organizer Virginia Trimble invited me to speak on The Future of Theoretical Cosmology.
Of course nobody has any idea what the future of theoretical cosmology will be like, given that we know neither what future experiments will tell us, nor what ideas future theorists will come up with.
