Some of the trippiest theories I've ever heard. At the heart of the Milky Way, a cluster of stars has baffled scientists, appearing as if they are forever young. A new theory proposes a mind-bending explanation that could rewrite our understanding of stellar evolution: These stars could be feeding off dark matter – powered indefinitely by the most mysterious substance in the universe.  Studying these objects may lead to breakthroughs in our understanding of dark matter and the universe itself. Some even speculate that dark matter may even organize into forms of dark life. The only way to know for sure is to keep looking.
