What does that mean? Well, it means that we were already really sure about the Higgs, and now we're even more sure. But there's still a lot we're not sure about, like whether the Higgs that we've found is actually the Higgs that we've theorized about, the one that fits perfectly into our Standard Model of the universe. That's going to take a lot more science. But at least we can be nearly 6-sigma sure that we've found something very interesting.
