We know that dark matter exists, but, irritatingly, we don’t know what it is.
One way to figure that out is to look for signs of it here on Earth, using subatomic particle detectors. But a new idea just published in a scientific journal is that we need to go bigger. A lot bigger: Using
entire exoplanets as detectors.
I give them points for thinking originally, for sure. matter directly. It affects the way galaxies rotate, the way galaxies behave in clusters, the way clusters affect the light of objects behind them, and a host of other things, too. We know it exists. And over the decades people have looked for it, but almost everything that could possibly work has been eliminated. It’s not teeny black holes, or rogue planets, or cold gas. Nothing made of normal matter works, leaving only “exotic” subatomic particles like axions as candidates. Attempts have been made to look for those, too, but so far zip.

Studying black holes enables scientists to learn more about the lives of stars – how they form and die. However, finding a black hole is quite a tricky task because they don t emit the same rays as most other celestial objects.
Researchers from The Ohio State University claim to have discovered the closest-known black hole to Earth. According to the findings of their study, which was published recenly in the journal Monthly Notices of the Royal Astronomical Society, it is located in the Milky Way and is 1,500 light-years away from Earth.
