The universe has cooked up all sorts of bizarre and beautiful forms of matter, from blazing stars to purring cats, out of just three basic ingredients. Electrons and two types of quarks, dubbed “up” ...

For more than half a century, scientists have tried to understand dark matter—a mysterious form of matter that doesn’t emit or absorb light but is thought to make up most of the universe’s mass. Its ...
