The history of dark matter searches is a long string of non-detections. When does theory have to face reality?To finish reading, click on "Will Dark Matter Hunters Ever Give Up?". In a related article that has some interesting background information, see "Dark Matter Search Keeps Coming Up Empty".
The standard big-bang cosmology requires lots of mysterious unknown stuff labeled ‘dark matter.’ Cosmologists are convinced it exists, because otherwise galaxies and clusters of galaxies would quickly fall apart (quickly, that is, in moyboy cosmological terms). Theory requires that 85% of the universe is made up of this invisible matter that doesn’t emit electromagnetic radiation, but has gravity. Another 11% consists of dark energy, which is also completely unknown. That leaves only about 4% of reality accessible to observation.
Here are some of the most recent searches for dark matter and negative results.
