George F. R. Ellis, FRS, (born August 11, 1939) is the Distinguished Professor of Complex Systems in the Department of Mathematics and Applied Mathematics at the University of Cape Town in South Africa. He co-authored "The Large Scale Structure of Space-Time" with University of Cambridge physicist Stephen Hawking, published in 1973, and is considered one of the world's leading theorists in cosmology. He is an active Quaker and in 2004 he won the Templeton Prize [ [http://www.templetonprize.org/news_templetonprize_2004.html Templeton Prize for Progress Toward Research or Discoveries about Spiritual Realities ] ] . From 1989 to 1992 he served as President of the [http://grg.maths.qmul.ac.uk/grgsoc/ International Society on General Relativity and Gravitation] . Currently he is President of the International Society for Science and Religion.

Ellis was a vocal opponent of apartheid during the National Party reign in the 1970s and 1980s, and it is during this period that Ellis' research has focused on the more philosophical aspects of cosmology, for which he won the Templeton Prize. He was also awarded the Star of South Africa (Decoration) by Nelson Mandela, in 1999. On May 18, 2007, he was elected a Fellow of the British Royal Society.

In 2005 Ellis appeared as a guest speaker at the Nobel Conference in St. Peter, Minnesota.

Ideas

George Ellis proposed a model universe that contains a naked singularity as a recycling mechanism, which he claims gives almost as good a description of the real universe as the conventional model.

The Ellis universe is like a cylinder-shaped universe, except that the Earth is located on one side and a naked singularity on the other. There is no cosmic inflation – the galaxies are arranged very unevenly, with a great deal of material crowded round the singularity, and very little near the Earth. The effect of such a distribution of matter is to produce a red shift of light that, at the Earth, has the same characteristics as if the galaxies were receding.

In terms of philosophy of science, Ellis is a Platonist.
