Since dark matter is found in young and old galaxies, we know a few things about the particles that comprise it.
For instance, if dark matter had a mass the same as a proton, about a million dark matter particles would stream through a liter of water per second. But don't worry, we still have never observed any interaction between dark matter and matter ! (But we hope to !)
If dark matter is steaming through the earth, we need a very sensitive detector to measure its interactions.
The DAMIC experiment is designed to detect several potential types of dark matter spanning more than 7 orders of magnitude in mass.
DAMIC-M will probe, for the first time, several classes of predicted dark matter that have specific rates and masses.
What's so good about DAMIC-M ?
