Invisible "dark matter"—what cosmologists call the mysterious glue that holds everything together—is estimated to make up more than a quarter of the universe. In chemistry, dark matter refers to the thousands of small molecules in bone and tissue that can't be identified using mass spectrometry. They make up the vast majority of what's known as metabolites.
