A Brief Comment on "The Pyrotechnic Universe"
Justin Khoury, Burt A. Ovrut, Paul J. Steinhardt, Neil Turok
Abstract
We respond to the criticisms by Kallosh, Kofman and Linde concerning our proposal of the ekpyrotic universe scenario. We point out a number of errors in their considerations and argue that, at this stage, the ekpyrotic model is a possible alternative to inflationary cosmology as a description of the very early universe.
