Does any of this really matter?
It matters more often than not. Just barely.
Well if you don’t care to know how the universe around you works then no. Hell, Jupiter has 63 moons, the moon has craters, a tree falls in the freakin woods. The point is, now we know. Maybe in 100 years we’ll think of some use for meson decay but for now it was absolutly worth it to make this discovery. I’ve thought of this issue myself from time to time and now I know that all the matter in the universe was created from a 1% varience in the creation of matter vs. antimatter.
What’s a matter, you? ;)
