- Sean M. Carroll
Sean M. Carroll (born 1966) is a senior research associate in the Department of Physics at the
California Institute of Technology. He is a theoretical cosmologist specializing in dark energyand general relativity. He is also a contributor to the physics blogCosmic Variance, and has written for science magazines such as "Nature", "Seed", "Sky & Telescope", and "New Scientist". He is the author of "Spacetime And Geometry", a graduate-level textbook in general relativity, and has also recorded a set of lectures for the Teaching Companyentitled "Dark Matter, Dark Energy: The Dark Side of the Universe".
He is an outspoken
atheist, who argues that scientific thinking leads one to a materialist worldview. [ [http://preposterousuniverse.com/writings/nd-paper/ Why Almost All Cosmologists Are Atheists] ] [ [http://cosmicvariance.com/2006/10/29/the-god-conundrum/ The God Conundrum - Cosmic Variance blog] ] He turned down an invitation to speak at a conference sponsored by the John Templeton Foundation, on the grounds that he did not want to appear to be supporting a reconciliation between science and religion. [ [http://preposterousuniverse.blogspot.com/2005/04/purity-of-essence.html Purity of Essence -Preposterous Universe blog] ] In 2004 he and Shadi Bartschtaught an undergraduate course at the University of Chicago on the history of atheism.

Carroll received his Ph.D. in Astronomy and Astrophysics in 1993 from
Harvard University, where his advisor was George B. Field. He worked as a postdoctoral researcher at the Massachusetts Institute of Technologyand Kavli Institute for Theoretical Physicsat the University of California, Santa Barbara, and as an assistant professor at the University of Chicagountil 2006.

*Spontaneous inflation as a solution to the
arrow of timeproblem. Carroll and Jennifer Chen posit that the Big Bangis not a unique occurrence as a result of all of the matter and energy in the universe originating in a singularity at the beginning of time, but rather one of many cosmic inflationevents resulting from quantum fluctuations of vacuum energyin a cold De Sitter space. Carroll and Chen claim that the universe is infinitely old, but never reaches thermodynamic equilibriumas entropy increases continuously without limit due to the decreasing matter and energy density attributable to recurrent cosmic inflation. They assert that the universe is "statistically time-symmetric" insofar as it contains equal progressions of time "both forward and backward". [Sean M.
