There’s no question that quantum fluctuations play a crucial role in modern cosmology, as the recent BICEP2 observations have reminded us. According to inflation, all of the structures we see in the universe, from galaxies up to superclusters and beyond, … Continue reading
“Teleology” is a naughty word in certain circles — largely the circles that I often move in myself, namely physicists or other scientists who know what the word “teleology” means. To wit, it’s the concept of “being directed toward a … Continue reading
I mentioned some time back the Closer to Truth series, in which Robert Lawrence Kuhn chats with scientists, philosophers, and theologians about the Big Questions. Apparently some excerpts are now appearing on YouTube — here I am talking about whether … Continue reading
Kim Boddy and I have just written a new paper, with maybe my favorite title ever. Can the Higgs Boson Save Us From the Menace of the Boltzmann Brains? Kimberly K. Boddy, Sean M. Carroll (Submitted on 21 Aug 2013) … Continue reading
Greetings from sunny Santa Cruz, where we’re in week three of the Summer School on Philosophy of Cosmology. I gave two lectures yesterday afternoon, and in a technological miracle they’ve already appeared on YouTube. The audio and video aren’t perfect … Continue reading
Going on right now, up at UC Santa Cruz — I guess the official name is the UCSC Institute for the Philosophy of Cosmology. It’s a three-week event, with talks by some top-notch people: David Albert, David Wallace, Tim Maudlin, … Continue reading
Lee Smolin has a new book out, Time Reborn: From the Crisis in Physics to the Future of the Universe. His previous subtitle lamented “the fall of a science,” while this one warns of a crisis in physics, so you … Continue reading
Completing an action-packed trilogy that began with quantum mechanics and picked up speed with the Higgs boson, here I am talking with Brady Haran of Sixty Symbols about the arrow of time. If you’d like something more in-depth, I can … Continue reading
Don’t forget that the deadline for this year’s Flame Challenge is coming up. Your mission: to explain “Time” to a group of 11-year-olds, who will be sternly judging your work. Get your submissions in by March 1, either video or … Continue reading
