Higgs Boson

Because the results observed , in the extreme conditions created in the LHC, are exactly the results which the theory predicted would be observed in those extreme conditions, as a result of the existence of the Higgs boson.It's always possible that something else has produced these results - but as people here often say, a scientific theory is the best explanation we can currently find of observed phenomena, and right now, I have not heard of any theory which predicts these results, other than the theory which involves the existence of the Higgs boson. It is therefore the best explanation.(As I understand it, we are, however, only 99.99994% certain.)

The only way you will upset the apple cart of established physics, is by setting out, with cogent mathematics, a comprehensive competing theory, which allows you to make mathematically based predictions, which can in turn be tested and verified in experiments.That's what Einstein did. It's what the group of scientists who include Professor Higgs did. They sat down and did the maths and came up with the predictions. Those predictions have, in the case of the Higgs-like boson, now been tested and verified to a confidence level of 99.99996%. In the case of Einstein, they've been tested in numerous ways - you and I test them most days when we use our SatNavs and don't end up in a river.You won't upset apple carts by saying things like "they both result from the interaction of matter waves". That's an interesting phrase, but without the maths, it has no meaning in science.Show us your maths.
