Celestial objects known as dark dwarfs may be hiding at the center of our galaxy and could offer key clues to uncover the nature of one of the most mysterious and fundamental phenomena in contemporary cosmology: dark matter.

What we know today about dark matter is that it exists and how it behaves—but not yet what it actually is. Over the past 50 years, several hypotheses have been proposed, but none have yet gathered enough experimental evidence to prevail. Studies like the one by Sakstein and colleagues are important because they offer concrete tools to break this deadlock.
