I study dark matter, cosmology, and particle physics for a living at UC Berkeley and Lawrence Berkeley National Lab. On the weekends I write explainers about surprising places physics shows up in the natural world.

If these two droplets combine (often because the droplets grow because of humidity in the air), the whole system suddenly has way more energy than it ought to—the two-droplet configuration had more energy than the mega-droplet configuration should, and that extra energy has to go somewhere…
