So, today they say that the Large Hadron Collider has found the Higgs Boson, and at least one person so far has asked me to explain this. So here goes.
First of all, let's get over this ridiculous idea of calling "the God Particle", because it's not God and has nothing to do with God really, except insofar as everything has something to do with God, who either created it all or doesn't exist, depending on your take on things, but let's not get into that here.
The Higgs Boson is very small, which is why it's so hard to find, but it can also explain why other stuff is heavy, which is why they thought of it in the first place. Think of it as having mice in your house: you may not be able to see them, but then you find poo in a cupboard, and your cereal boxes have been gnawed, and you think "maybe I have mice". As with mice, so with the Higgs Boson, because it is too small to see, but the Scientists have seen things which suggest it might exist, such as teeth marks on other particles and things.
With mice, you can just get a cat or put traps out or things, but with the Higgs Boson, you have to build a Big Machine and do Experiments, and even then you can't really be sure that you've found a Higgs Boson, but you can be reasonably certain, and this is what has happened. To be precise,
they ha[ve] attained a confidence level just at the "five-sigma" pointwhich means it is quite likely to be the Higgs Boson, but also maybe someone sneezed or wrote down the wrong number or something.
Also, although it is referred to as "The" Higgs Boson, this is a little bit misleading, as there are actually lots of them, and not just one, but so far they have only found one of them. To find more they will have to build a new Big Machine in another place, where a different Higgs Boson lives.
