The Dark Matter Hunting Experiments

We don't know that dark matter has any interactions at all. The experiments have basically ruled out the kind of particle that would perfectly satisfy the miracle. It's a veryweak interaction. So you need a huge tank of stuff in you to wait years, and when it bumps into the gas atom or particle, it'll create a little electron,. Then to the measure, and you can sey, hey, something bumped into my zenon gas. It must be dark matter.
