Boy, does this.
We have ideas, and we have some conclusions, but overall what we have here is a mystery. Actually, at least two, for with two nucleons merging with each other on rare occasion we likely have a new sort of particle, one composed of 6 quarks instead of the usual three. And a 6 quark body made stable by the conditions in a nucleus.
What do we call it? A super hadron? A meta hadron maybe. And what are it's properties. What are the differences between a standard iron atom and one with one or more super hadrons? And how do you designate them?
And where they do exist in a nucleus what do they make possible? Could they be a source of a force or forces beyond the electromagnetic?
This raises questions as it answers one. That my friends is science.
