    Hi All; Question from a non-physicist. If the Higgs field is the mechanism that conveys mass to elementary particles in the standard model, what mechanism conveys mass to a Higgs particle? Cheers.

    I think physicists concider the higgs boson as the answer, not the part of where more questions are needed. The higgs boson is the mechanism for conveiing mass. Though i'll hold on to my answer untill an actual physicist gets here.. haha..


    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    The Higgs field is self-interacting, much like the gravitational field.

    The Higgs interacts with itself, thereby acquiring mass.
    The gravitational field is also its own source, contributing to its own strength.

    The Higgs field wabbles out Higgs bosons, just as electric field wabbles out photons.

    Thanks for the replies. My thread title wasn't the greatest; it should have been "How does Higgs Give Itself Mass", or something along those lines.

    Interesting that a gravitational field can interact and reenforce itself. I did not know that.

    Yup. The reason is also quite intuitive - in General Relativity all forms of energy are a source of the gravitational field. The the gravitational field itself also contains energy, it is of course in itself a source...
    This self-interaction is one of the reasons why the field equations are so non-linear.

    This is probably a dumb question (I'm a layman, not a physicist or a mathematician): when gravity uses itself as an energy source, what is the offset in the energy equation vis a vis the law of conservation of energy? Note: if it involves equations, don't worry about an answer, I'll have take your word for it

    Energy remains conserved globally, because it stays in the field, so there is no violation. The point is simply that the field influences its own geometry.
