To show what dark matter is or at least see it? It's like water , if you add a dye you can see the water better. Any other thing that could show dark matter besides this possibility?
Not sure how mixing antimater with dark matter would make dark matter visible. Besides everytime we make antimatter there is dark matter there too.
But wouldn't there be a reaction when the two collide and annihilate each other and be seen by cameras ?
You would need antidarkmatter to react with dark matter to cause an annihilation. You need the antimatter counterparts to cause a reaction. electrons and positrons mutually annihilate but but electrons and anti-neutrons don't, for example.
But since we don't know what dark matter is , would it be worthwhile to try this experiment because of that one thing?
If it were something that would react with anything that we already know about, have access to, we would already know what it is. So, no it is not a worthwhile experiment.
