Question: What is your latest theory on why we are here, rather than annihilated by antimatter?

That’s a good question.

There are various theories for how we could be here, and not annihilated by antimatter. Most of them say that for some reason, there must be a difference between matter and antimatter. This difference make it so there’s less antimatter than matter. Different people have different theories on what the difference could be.

My experiment searches for one particular type of difference between matter and antimatter. So far we haven’t found anything, but fingers crossed!
