Carroll has worked on a number of areas of theoretical cosmology, field theory and gravitation theory. His research papers include models of, and experimental constraints on, violations of Lorentz invariance; the appearance of closed timelike curves in general relativity; varieties of topological defects in field theory; and cosmological dynamics of extra spacetime dimensions. He has written extensively on models of dark energy and its interactions with ordinary matter and dar… Web1M views 11 years ago Sean Carroll is a theoretical physicist at Caltech.

Webexcitations have negative energy. So empty space can decay into positive-energy gravitons and negative-energy particles. Can be avoided if we put a cutoff on the theory. Theorists need to be careful, but observers should keep an open mind. Nobody ever measures w, really. We only measure the behavior of the scale factor. g g [Carroll ... WebFeb 22, 2010 · The notion of dark energy is peculiar, even by cosmological standards. Cosmologists have foisted the idea upon us to explain the apparent accelerating expansion of the Universe. They say that this acceleration is caused by energy that fills space at a density of 10^-10 joules per cubic metre.
