The Higgs has been discovered. Does that count? Anything comprised of electrons can't be massless.

 

The discovery of the Higgs is evidence, so yes, I agree it may count, as it was something predicted by theory.

 

On reading the Wikepedia explanation of how the Higgs mechanism gives mass to particles, it is very complicated.

 

I have a few questions:

 

Does the Higgs field give particles inertia, i.e. is that what giving mass to a particle, means?

 

If so, how the does the Higgs field avoid giving a particle continuous inertia that slows it down continuously?

 

And how does the Higgs field give a particle inertia according to Relativity, as presumably, a moving particle is not moving in its own reference frame, and so what reference frame is the Higgs field in when it interacts with a particle?

In some sense, yes. But inertia is not really a prominent concept in quantum physics.

Inertia does not slow down objects.

Maybe I need to take a step back on this first...

 

Do we understand how the electron and proton have the property of inertia?

 

If so, what is the explanation?

If so, what is the explanation?

 

One particle is giving it's kinetic energy to other particle and slowing down.

If entire kinetic energy is given, source particle is stopped, and other particle is accelerated.

If just part of energy is given then both particles after collision are moving.

 

With relativistic speeds particle colliding with other particle will create other particles.

What will be created depends on amount of kinetic energy.

v=0.36c will create additional pion 0 from proton and proton collision (or in other scenario pion+ and neutron and proton).

v>0.9c will create additional proton and antiproton from proton and proton collision.

 

It was nicely described in the article I gave link above.

This thread is about the Higgs. Please stay on that topic.

The Higgs "particle" has a short name.

 

It'll have a short life-span. In 50 years, it'll be history, like Q-Rays, Protoplasm or the Currant-Bun Atom.

No, that's not what I meant by on-topic.

Sorry, I didn't realise the Higgs cannot be questioned, I suppose it's an article of faith, like Global Warming?

Not at all. But we have rules on this site, as you should know by now, and a science thread is for answering questions asked by the OP with mainstream science. If you want to propose that some aspect of science an article of faith, do it in speculations. Here, such a suggestion is off-topic.
