Forums relating to this have been up constantly, but just to clarify, they are not one and the same, to the best of my knowledge. Higgs causes mass, Graviton causes gravity. Higgs has an influence on the graviton, if you think about it. The Higgs boson causes mass which in turn is affected by a graviton in a gravitational field. put it this way, a graviton causes weight. Mass is not influenced by weight and is constant, but weight changes due to different Gravitational field strengths. Mass can only be quantified by finding weight and multiplying this by 9.81 (approx., on Earth) mass affects gravity, but they are not the same thing, so why should Higgs and Graviton be the same thing. If anyone would like to contest me on this view, feel free to reply to this thread. Any criticisms or support will be welcome as I want to enhance my knowledge further.
