Sean M. Carroll, theoretical cosmologist and popular science writer.

Prof. Robert H. Brandenberger, (born 1960) is a theoretical cosmologist and a professor of physics at McGill University in Montreal, Quebec.

His students would know, of course, probably several high-level theoretical cosmologists.

Michael S. Turner is a theoretical cosmologist, who coined the term dark energy in 1998.

Liddle is a theoretical cosmologist and is interested in understanding the properties of our Universe and how these relate to fundamental physical laws.

Experiments and predictions of theory have forced theoretical cosmologist to reconsider previously unthinkable assumptions - like: Can things travel faster than the speed of light (inflation)?

There he met the theoretical cosmologist R. C. Tolman, and studied relativistic cosmology.

He is a theoretical cosmologist specializing in dark energy and general relativity.

Replies: Some theoretical cosmologists have posed the question, "What are the implications if the speed of light has changed over the lifetime of the Universe?"

Mark Trodden (born 1968) is a theoretical cosmologist and particle physicist.
