Dr. Sean Carroll is the Homewood Professor of Natural Philosophy at Johns Hopkins University in Baltimore, effectively a co-appointment in physics and philosophy, and the Fractals Department at the Santa Fe Institute. Most of his career has been devoted to cosmology, field theory, and gravitational research, including dark matter and dark energy, modified gravity, topological defects, extra dimensions, and fundamental symmetry breaking. I’m keeping an eye on the topic. More recently, his focus has been on more fundamental problems in both quantum mechanics (origin of probability, appearance in space and time) and statistical mechanics (entropy and time arrows, appearance and causality, complexity dynamics). is moving to A philosophical dimension to his work.
Each of us has our own version of the multiverse in our heads.
