CWmike writes "With a new $2 billion device successfully installed Thursday, the International Space Station has become a dark matter hunter. Two robotic arms worked in tandem to lift the 15,251- pound instrument, called the Alpha Magnetic Spectrometer-2 (AMS-2), out of space shuttle Endeavour's payload bay and then attached it to the backbone of the space station. The instrument will orbit the Earth sifting through cosmic particles, providing data that it is hoped will help find the answers to fundamental questions of physics related to antimatter and dark matter. The main goal of this research is to understand the origin of the universe."
