The Biggest Ideas in the Universe | Q&A 18 - Atoms

The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.

This is the Q&A video for Idea #18, "Atoms." A bunch of good questions this week. Why certain particles decay into other ones, can there be negative-mass particles, and how do we know there aren't noticeable forces we haven't yet discovered? There's even a plot of experimental constraints!
