WIMPs: cool stuff that could be what Dark Matter is made of
<p>First of all it should not interact with photons (light) — or else we’d be able to see them and we can’t see them.</p>
<p>It cannot interact via the strong force or electromagnetic force — or else we’d be able to detect it through those interactions with baryonic matter*, like for example, we know it doesn’t interact via the strong force because otherwise it would interact with cosmic rays. (*baryonic matter is just the matter made up of protons and neutrons, all the normal matter. Baryon means that it is made of 3 quarks (you can google standard model picture to see what a quark is) just like protons and neutrons)</p>
