And so again, the baryonic asymmetry remains a mystery.

It always seems to me that there is a certain amount of frustration in performing experiments like this. It's fantastically hard to achieve technologically, and there's a certain sense of accomplishment in just being able to do the experiment. But you also know going into it that your results are almost certainly going to be exactly what you expect, just like they were in this case.

I suspect there's a significant number of researchers who want surprises -- as Asimov noted, it's not the "hey, it worked!" experiments but the "well, that's odd..." ones that can change things.

Well, in the area of CPT symmetry research, it's definitely true. Lots of people are doing very good, precise work to show that the symmetry holds, and they know that if their results are good, they will get a paper published in a good journal. But if they find something unusual and can demonstrate it, then they will get a paper in a top journal and a Nobel prize and a professorship wherever they want.
