The Higgs boson gives particles mass. And the graviton is the theoretical force-carrier of gravity. Gravity depends on mass. So if the Higgs Boson gives things mass, it therefore gives them gravity. Is the Higgs Boson the same thing as a Graviton? Or is there a difference? The only thing I know is that the Higgs Field is something very different from the Gravitational Field. Yet, I'm not satisfied with that fact. I want to know why the Higgs Boson is not the Graviton.

You say:
but this is not so. The source of the gravitational field is an object called the stress-energy tensor. One element of this object is the energy density, and mass contributes to this through Einstein's well known equation $E = mc^2$, but mass is not required to generate a gravitational field. Even massless particles like photons generate a gravitational field. The Higgs boson, as discovered at the LHC, is a low energy effect of the Higgs field, and it's the Higgs field that is responsible for the mass of the elementary particles. So it's not even correct to say that the Higgs boson gives particles mass. The graviton is the carrier of the gravitional force if you describe that force by a quantum field theory. Whether gravitons are a useful way to describe quantum gravity is not clear. However, what is clear is that the graviton and Higgs boson are entirely unrelated. |

You basically answered your own question: Mass is the source of gravity. The Higgs particle plays a role in creating this source, while the graviton plays a role in explaining the mechanism of gravity (but not what causes it to be there in the first place). |

Mass is a measure of the " inductance " of a particle. The inductance filters quantum vacuum frequencies. Gravity is the resulting Casmir Force |
