When we think of the universe, we usually imagine planets orbiting stars, and those stars orbiting the core of their galaxy. Not only is dark matter apparently invisible, but it also doesn’t behave like other matter. As far as we can tell, of the four fundamental forces, dark matter only really interacts through gravity. According to Bai and colleagues, the same methods could be used in the hunt for dark matter planets, if they do indeed exist. The underlying thinking is that dark matter, and therefore dark exoplanets, may react weakly with electromagnetic fields.
