\begin{abstract}
I'm a cosmologist specializing in the very, very, very early Universe
(cosmological inflation), with interests in black holes and gravity, the
foundations of quantum mechanics, the arrow of time, and other
fun-and-bewildering things. My favorite subjects are those that sound
somewhat crazy, but arise from following our current best physical
theories where they lead. The inflationary ``multiverse'' is a good
example, and my recent research mostly concerns observable signatures of
other bubble ``universes'' crashing into ours. In 2006, Max Tegmark and
I created the Foundational Questions Institute to support research
worldwide on the foundations of physics and cosmology where the
questions are so risky, or ``big'' that conventional funding is hard to
come by. If you enjoy thinking about the stuff on this thread, there's
lots of good material at the FQXi community site. Last year, I joined
Max and several others in founding the Future of Life Institute, which
seeks to minimize the risk/reward ratio in world-changing emerging
technologies such as AI and Genetic engineering. Like other universes
and black holes, when you talk a lot about these technologies they can
sound crazy. But they're coming! Most recently, with astrophysicist Greg
Laughlin, I started the Metaculus project, an effort to create
high-quality crowdsourced predictions about scientific and technological
impact and breakthroughs, to help us understand what science and
technology we should keep our eyes on. (Looking for more users -- if you
like to predict or think about the future, check it out!) Edit: 5 PST,
periodically checking in to answer a few more%
