Famous and not so famous Cosmologists
Hello All
I thought maybe discussing the works of some cosmologists maybe fun.
What do you think?
and maybe pay tribute to their work

and some papers from Hannes Alfven and Halton ArpRalph Asher Alpher authored his Ph.D. dissertation on the Big Bang theory in 1948. His mathematical formula brought into being the scientific theory of the origin of the universe. His paper said the universe occurred 14 billion years ago with a superhot explosion and later, in 1948, Alpher showed proof. No one accepted these ridiculous ideas until 1964 when two radio astronomers showed Alpher's theory was correct. Unfortunately, they received the Nobel Prize, not Ralph Alpher.

Hannes Alfvén is an original contributor to the potent new discipline of magnetohydrodynamic, to which he brings a background of work in such varied and related fields as cosmic rays, fundamental electronics, aurorae, earth magnetism, sunspots, and the design of electron tubes. He was born in 1908 at Norrköting, Sweden, and educated at the University of Uppsala. Since 1940, he has been professor at the Royal Institute of Technology, Stockholm. [He died in 1995. Biography]

Halton Arp's discoveries about red shift.
http://www.electric-cosmos.org/arp.htm
Halton C. Arp is a professional astronomer who, earlier in his career, was Edwin Hubble's assistant. He has earned the Helen B.Warner prize, the Newcomb Cleveland award and the Alexander von Humboldt Senior Scientist Award. For years he worked at the Mt. Palomar and Mt. Wilson observatories. While there, he developed his well known catalog of "Peculiar Galaxies" that are misshapen or irregular in appearance.
Arp discovered, by taking photographs through the big telescopes, that many pairs of quasars (quasi-stellar objects) which have extremely high redshift z values (and are therefore thought to be receding from us very rapidly - and thus must be located at a great distance from us) are physically associated with galaxies that have low redshift and are known to be relatively close by. Arp has photographs of many pairs of high redshift quasars that are symmetrically located on either side of what he suggests are their parent, low redshift galaxies. These pairings occur much more often than the probabilities of random placement would allow. Mainstream astrophysicists try to explain away Arp's observations of connected galaxies and quasars as being "illusions" or "coincidences of apparent location". But, the large number of physically associated quasars and low red shift galaxies that he has photographed and cataloged defies that evasion. It simply happens too often
Because of Arp's photos, the assumption that high red shift objects have to be very far away - on which the "Big Bang" theory and all of "accepted cosmology" is based - is proven to be wrong! The Big Bang theory is therefore falsified.

Hello All
Hermann Bondi
Hermann Bondi
Professor Sir Hermann Bondi, KCB , FRS (1 November 1919–10 September 2005) was an Anglo-Austrian mathematician and cosmologist. He is best known for developing the steady-state theory of the universe with Fred Hoyle and Thomas Gold as an alternative to the Big Bang theory, but his most lasting legacy will probably be his important contributions to the theory of general relativity.
Don't you love reading about the journey of these cosmologists.In 1948, Bondi, Hoyle and Gold formulated the steady-state theory, which holds that the universe is constantly expanding but matter is constantly created to form new stars and galaxies to maintain a constant average density. It is probably fair to say that this theory dominated over the rival Big Bang theory until the discovery of the cosmic background radiation caused a sudden change in fortune.
Bondi was a major contributor to the golden age of general relativity (roughly 1960-1975). He was one of the first to correctly appreciate the nature of gravitational radiation, introducing Bondi radiation coordinates, the Bondi k-calculus, and the notion of Bondi mass, and writing influential review articles. He popularized the sticky bead argument which was said to be originally due, anonymously, to Richard Feynman, for the claim that physically meaningful gravitational radiation is indeed predicted by general relativity, an assertion which was controversial up until about 1955. An influential 1947 paper revived interest in the Lemaitre-Tolman metric, an inhomogeneous, spherically symmetric dust solution (often called the LTB or Lemaître-Tolman-Bondi metric). Bondi also contributed to the theory of accretion of matter from a cloud of gas onto a star or a black hole, working with Raymond Lyttleton and giving his name to "Bondi accretion" and the "Bondi radius".
He became a professor at King's College London in 1954, and was given the title of Emeritus Professor there in 1985. He was secretary of the Royal Astronomical Society from 1956 to 1964.

He should have shared in the 1978 Nobel Prize with Penzias and Wilson!!!
Fight ignorance!
Perhaps an operational definition of "cosmologist" might be helpful.
How far back in history should we look?
What minimal 'theory' component should a candidate cosmologist's work include for serious consideration?
If 'cosmology' is defined as having something to do with the (quantitative, scientific) study of the nature of the universe as a whole, to what extent should we use contemporaneous definitions of 'universe' and 'science' in considering candidates?

Hello Neried
Its good to see the historical cosmologists as well. With limited tools and info some came up with great ideas.

1933 - Edward Milne names and formalizes the cosmological principle
1934 - Georges Lemaître interprets the cosmological constant as due to a vacuum energy with an unusual perfect fluid equation of state
1938 - Paul Dirac suggests the large numbers hypothesis, that the gravitational constant may be small because it is decreasing slowly with time

1948 - Hermann Bondi, Thomas Gold, and Fred Hoyle propose steady state cosmologies based on the perfect cosmological principle
1948 - George Gamow predicts the existence of the cosmic microwave background radiation by considering the behavior of primordial radiation in an expanding universe.

1981 - Viacheslav Mukhanov and G. Chibisov propose that quantum fluctuations could lead to large scale structure in an inflationary universe
1981 - Alan Guth proposes the inflationary Big Bang universe as a possible solution to the horizon and flatness problems
1990 - Preliminary results from NASA's COBE mission confirm the cosmic microwave background radiation is an isotropic blackbody to an astonishing one part in 105 precision, thus eliminating the possibility of an integrated starlight model proposed for the background by steady state enthusiasts.
1990s - Ground based cosmic microwave background experiments measure the first peak, determine that the universe is geometrically flat.
1998 - Controversial evidence for the fine structure constant varying over the lifetime of the universe is first published.
1998 - Adam Riess, Saul Perlmutter and others discover the cosmic acceleration in observations of Type Ia supernovae providing the first evidence for a non-zero cosmological constant.
1999 - Measurements of the cosmic microwave background radiation (most notably by the BOOMERanG experiment see Mauskopf et al., 1999, Melchiorri et al., 1999, de Bernardis et al. 2000) provide evidence for oscillations (peaks) in the anisotropy angular spectrum as expected in the standard model of cosmological structure formation. These results indicates that the geometry of the universe is flat. Together with large scale structure data, this provides complementary evidence for a non-zero cosmological constant.
[edit] Since 2000
2003 - NASA's WMAP takes more detailed pictures of the cosmic microwave background radiation than were obtained by the BOOMERanG experiment. The image can be interpreted to indicate that the universe is 13.7 billion years old (within one percent error) and confirm that the Lambda-CDM model and the inflationary theory are correct.
2003- An apparent periodicity in the cosmic microwave background led to the suggestion, by Jean-Pierre Luminet of the Observatoire de Paris and colleagues, that the shape of the Universe is a finite dodecahedron, attached to itself by each pair of opposite faces to form a Poincaré sphere. ("Is the universe a dodecahedron?", article at PhysicsWeb.) During the following year, astronomers searched for more evidence to support this hypothesis but found none.
2006 - The long-awaited three-year WMAP results are released, confirming previous analysis, correcting several points, and including polarization data.

That's an interesting list harry.
Do you mind if I ask whether the source was copyright?
Also, is there any particular reason why it seems so heavily focused (biased?), for its pre-16th century coverage, on a tiny minority of civilizations?
If you were to guess, based on this list, as it is, would you say that names such as Hoyle*, Alfvén, and Luminet will disappear within a century or so, from future versions of such a list?
Pace craterchains, to what extent does this list include only those who have done quantitative work (post-16th century)?
Why do you think Arp's name is not anywhere to be found on the list?
*wrt 'steady state' ... in fact, Hoyle is only on this list for reasons other than 'steady state'!

Oh, and I really don't know what "Get over it" means; would you be so kind as to elaborate please?

(edited to add)
In the realm of cosmologists, and even that of the true persuit of knowledge, I would have to nominate Charles Fort. A researcher and writer of the early 1900's. His fortitude earned him the knowledge of what took place in our solar system, but not the why.

Hello All
Neried is right.
I thought I gave a ref link.
Darn
