Summary:
- The International Space Station (ISS) hosts an experiment called the Alpha Magnetic Spectrometer (AMS) that is studying antimatter in the universe.
- The AMS measures cosmic rays and has detected an excess of positrons, the antimatter counterpart of electrons, which could provide clues about the origins of dark matter.
- The extreme cold temperatures on the ISS, which can reach -300°F, are crucial for the AMS to operate effectively and collect data on these antimatter particles.
