Connecting Ultrasmall and Ultralarge

Cosmic questions find answers in fundamental physics. The structure of the Universe was imprinted in its earliest moments, when the Big Bang created conditions so extreme that they challenge our understanding and imagination.

Powerful ideas from the Core, and unification beyond, help us rise to the challenge.

Why is there something rather than nothing? What is the dark matter? Does the Universe undergo violent upheavals, which change its basic character? Is everything we've seen only a small part of a vastly larger Multiverse? These are some of the questions we're wrestling with.

Five Easy Pieces

Just a few of my (non-technical) thoughts on cosmology. You can also find most, but not all of these, in Fantastic Realities.
