Understand the origin of Mass (Score:5, Interesting)
I'd like to pick option 1, but, actually, I've never really seen a good explanation of the Higgs mechanism; all the explanations I've seen end up being either way too superficial, or way too mathematical, so I have no idea what the origin of mass is even if the Higgs particle is found.
It doesn't help that the word "mass" is used in physics with at least five different meanings (connected meanings, of course, linked via relations such as the equivalence principle), and I'm not quite sure which meaning(s) of mass is(are) being explained.
Re:Understand the origin of Mass (Score:5, Interesting)
I'm no expert either. Apparently the proton's rest mass is 1% due to the Higgs and 99% due to the kinetic energy of its component quarks (energy mass). AFAICT the Higgs doesn't explain this 99%, M-E equivalence does; Higgs explains only the rest mass of the quarks.
I've heard claims that if the rest mass wasn't there, everything else would be super-mysterious, but photons seem to do OK with kinetic energy and no rest mass, so I'm as confused as you are about this Higgs thingy.
I think perhaps it's real importance is to complete the Standard Model, not really to explain mass, and that the explaining mass part is just a handy media soundbite.
Can anyone more knowledgeable inform us?
Re:Understand the origin of Mass (Score:5, Informative)
Its been a while, but the rest mass is the important part for making particles travel less than the speed of light. Light itself has kinetic mass for example, and yet it still travels at the speed of light.
Kinetic mass also has the property that it changes depending on your frame of reference. If you manage to push yourself up to the speed of light (so that you're traveling right along side some specific photon,) then you would measure that photon's mass as zero. A proton on the other hand would have a non-zero mass (its rest mass.) The Higgs mechanism is an explanation for why that non-zero mass exists.
One of Leonard Susskind's lectures goes into detail as to exactly what happens here, but its been a year or so since I watched those and I can't recall much details by now. All I really remember is that the Higgs is a scalar field and that there's some kind of pseudo-motion at the bottom of a Mexican hat function. The energy of the cross-motion (up and down the sides) interacts with real matter in some fashion giving rise to the observed rest masses. Or something like that! Might want to go watch the videos yourself in case my memory is more off-base than I think it is ;).

Higgs Mechanism Explained (Score:5, Interesting)
The other strange property that when you take all the energy out of the Higgs field the strength of the field does not go to zero. This is another big difference with, e.g. magnetic fields where no energy means that the field strength is zero. This property means that the universe is filled with a non-zero Higgs field because the lowest energy state of the field is when the strength is not zero. This non-zero field, filling the universe, is what fundamental particles bind to and this binding energy gives them a mass. So, fundamentally, the Higgs mechanism explains why mass is related to energy because all masses come from energy.
The final piece of the puzzle is why do we need to do all this instead of just give the particles a mass. This reasoning is a little complex but if we just give the particles masses this breaks an important symmetry which we see in nature. The Higgs mechanism gets around this by letting the physics be symmetric but having the universe (i.e. the environment) not be symmetric due to the non-zero Higgs field.

In short (and by my potentially incomplete understanding), the theory explains mass as a sort of drag introduced by the Higgs field. This serves to link mass and energy, explaining where rest mass comes from and why mass increases at relativistic velocities (higher drag). This is handy because we've 'known' for a while that mass is an artifact of energy but had no real explanation as to how/why. As far as "explaining mass", however, it does almost nothing: It replaces 'why does this have mass x' with 'why does this have y interaction with the Higgs field'. So indeed I'd not personally consider it as an "explanation for the origin of mass", but it is a step in the right direction (well, supposing it is right!).

No, actually it does a huge amount! The bit you are missing is that if you give particles mass then they break very important symmetries of nature (which in turn means that we would expect to see violations of conservation laws which are not observed). The Higgs mechanism gets around this by saying that while the laws of physics are symmetrical the universe is not. So while on the face of it may seem not to do much for mass behind the scenes it lets us have both the particle masses and the symmetries which we need to explain the universe.

The lighter particles are not "made out of" Higgs Bosons.
The Higgs Boson is the mediation particle for the Higgs field; it's the field that gives rest mass to quarks, not the boson itself (in the same way, photons don't make things electrically charged). The point is, the Higgs field equation turns into something in the Hamiltonian that looks exactly like a rest mass term, so we can say that the particles don't have that rest mass term intrinsically, but that it comes from the Higgs field interactions.
All this is easily gleaned from Wikipedia.

It's the details of exactly how this explains mass that is unclear. (and, which mass is explained?).

Or is it that the energy required to impart motion to particles accounted for by resistance of the Higgs field to motion by those particles in which case we are back to inertia and mass, albeit from a reverse perspective in that inertia explains mass? In which case we have photons merrily propagating at the speed of light since there is no resistance by the Higgs field?

The Higgs field is conjectured to be responsible for the rest mass of certain particles, in particular the quarks that make up protons and neutrons.

Without the Higgs field things would be just a few percent lighter.

Binding energy is what get's released when you form the various heavier particles - it's why quarks condense into hadrons, and why you need staggeringly high energy collisions to produce free quarks.

The Higgs serves to explain the mass of the W & Z bosons, plus the quarks that make up nucleons, but for various reasons (explained in the previous link), the mass of the individual constituent quarks does not contribute to the observed mass of the nucleons. Rather, that comes from back-reaction forces provided by QCD. The mass of neutrons & protons, and thus most normal matter, has been predicted by theory long ago.
