Scientists know — okay, are fairly certain — that only five percent of the universe is made up of stuff we can identify. The rest is "dark." Our measurements and calculations tell us something is there, but we just can't detect it. Twenty-seven percent of the universe is supposed to be made up of what's called dark matter, and researchers are doing everything they can to try and detect even a single particle of the stuff. In 2017, a team of researchers announced they were trying something different: instead of looking for particles, they're going to look for waves.
