There are 12 fundamental particles which make up everything in our universe. Prior to the other day, we could only detect 11 of them (the 12th being the Higgs Boson). Well, in Physics, there is something called the 'Standard Model'. The Standard Model is a mathematical description of the workings of our universe, describing how each of the 12 fundamental particles interact with one another, factoring in the influences of 3 of the 4 forces. These 3 forces are electromagnetism, the strong nuclear force, and the weak nuclear force. The 4th force, which isn't included, is gravity. Gravity is by far the weakest force, and doesn't have much of a significant effect on the tiny particles we are dealing with. However, we are still to create a Grand Unified Theory which does also include gravity. Anyway, back on topic. The Standard Model relies on the fact that the Higgs Boson does Infact exist. If the Higgs Boson didn't exist, then the Standard Model would be kind of worthless - as it would fall apart and things wouldn't make sense. The fact that the Higgs Boson does exist, and we have seen it, means that out Standard Model is accurate - which is great news for Physicists.
A lot of things in Physics are referred to as 'fields'. Well, the Higgs Boson is to do with the 'Higgs Field'. Think of the Higgs Field as an infinitely large pool of custard. Very shortly after the Big Bang (and I'm talking about like a millionth of a billionth of a billionth of a second after), everything was massless (like photons still are). Nothing had mass whatsoever. Until the Higgs Field was 'turned on' if you like. Back to the custard. This invisible Higgs Field has certain effects on the different fundamental particles, giving different particles more mass than others. The custard slowed some of the particles down a little, and some of them down a lot, meaning they have a larger mass than the ones which slowed a little. Photons however, are unaffected by the Higgs Field. Right inside you now, there are Higgs particles which give you your mass. Even in vacumes, there is a Higgs field. So even though we are taught that vacumes are bereft of particles, they still have Higgs Bosons within them. Mass doesn't get 'created'. A better term would be that mass is 'given'. Now that we have finally found the Higgs Boson, we can run further experiments to find out more about it to further our understanding, and hopefully make a better Grand Unified Theory, giving a more accurate explanation to the workings four universe.
As for stars not actually being where they seem to be that is because light is 'bent' by gravity. That's pretty much all you need to know!
You see what happens when you ask me about Physics? -.- can I do some maths now please?
