Are you avilable to answer questions about your research or what its like to try to use stuff from school in a real world science setting?

The weird thing is that the particles that we see every day are all normal matter (we usually make antimatter in accelerators), which prompts questions over why this normal matter is preferred over its twin, antimatter. It seems neither one should be preferred; there should be equal quantities of both. Or, if that were the case, perhaps it all should have annihilated and there should be no matter at all. This is a pretty big unsolved question in science, known as "baryon asymmetry." But yes, there's all types of animatter.

Are positrons the only anti-matter particles that we know of? Or am I just way off? I don’t know if you’re still writing and answering questions, but in the case that you are, I have one.
