Dark Matter Matters — When You Can’t Find It
There is a phantom in the machinery of the universe, and it evades even the best “ghost hunting” physicists.
Known for nearly 80 years, and for lack of a better terminology simply called “dark matter,” it still eludes detection to this day. Even our biggest particle accelerator, the Large Hadron Collider (LHC), apparently hasn’t been able to manufacture it.
Researchers at this week’s meeting of the American Association for the Advancement of Science (AAAS) reported that their Alpha Magnetic Spectrometer (AMS) on the International Space Station may yield new clues as to what dark matter is. This $1.5 billion “bug trap” experiment collects all kinds of exotic high-energy particles from deep space. Any unusual peaks in the count of particles monitored by the AMS might be the result of dark matter behavior. The AMS team are expected to release their results next month.
