This is important because it shows that they understand caution. They've found a new particle, and it appears to fit the current theories about what the Higgs-Boson should do. However it could be something else. The theory could be wrong. Even if this is something else they discovered a new particle. That alone is worth celebrating.
Less shouted from the rooftops news in Science but also important. We have observed Dark Matter. Stuff we've just had to assume existed but never could see because, well, it's Dark Stuff.
Oh I know a bunch of people, a few of them I'm related to, are wondering what all the fuss and roar is over. Get on with the actual useful stuff like cheap energy, or a car that can run off hopes and dreams, or an acid that can eat through red tape.
You can't just pick and choose what fields are useful. Way back in the mid 1800's oil was useless to most people. Right Now Whale Blubber isn't going to do the vast majority of the planet much good. You won't know what's going to be useful and what's stuck as Academia filler til you've looked and found and sorted and analyzed.
Take Eisenstein for instance. He found out gravity does things to
Who knows how this information will affect life. I don't. Could have applications in the day-to-day. Probably won't. Still. It's all added information that allows Scientists to focus from lots of competing theories to ones that take thse new observation into account.
And even if you feel both these discoveries are a gross waste of time having the ability to focus on one bit of nonsense instead of thousands is inherently a good thing.
