Sean Carroll: Physicist

 

I’m a theoretical physicist at Caltech in sunny Pasadena, California. I do research on theoretical aspects of cosmology, field theory, gravitation, and quantum mechanics. I want to learn about fundamental physics by studying the structure and evolution of the universe. These days I’m especially interested in inflation, the arrow of time, and how quantum mechanics intersects with cosmology. I’ve done work on dark matter and dark energy, modified gravity, topological defects, extra dimensions, and violations of fundamental symmetries. See my research page for more details.

I’ve written a couple of popular-level books: From Eternity to Here: The Quest for the Ultimate Theory of Time, and The Particle at the End of the Universe: How the Hunt for the Higgs Boson Leads Us to the Edge of a New World. I also wrote a graduate textbook, Spacetime and Geometry: An Introduction to General Relativity, and recorded lectures for the Teaching Company on Dark Matter and Dark Energy and the Mysteries of Time. I started blogging back in 2004, and keep it up to this day.

In addition to theoretical physics and book-writing, there are a bunch of other things I’m interested in, somewhat haphazardly collected on my activities page. If you’d like more details, see writingstalks or videos.

Distant Time and the Hint of a Multiverse:

Cosmologist Sean Carroll attacks — in an entertaining and thought-provoking tour through the nature of time and the universe — a deceptively simple question: Why does time exist at all? The potential answers point to a surprising view of the nature of the universe, and our place in it.
