← The Hunting of the Higgs: what is it and why does it matter?

But wait. James Woodward says the Higgs is NOT the origin of mass.

"We now know that at cosmic scale space is flat, so critical cosmic matter density obtains. That means that phi [the total scalar gravitational potential] equals c2. So, in Einstein's second law c2 can be replaced by phi, and now m * phi = E. It takes no genius to read this to say that E is the total gravitational potential energy -- and that the origin of E in SRT is due to the gravitational interaction. Since m arises from E (irrespective of whether E is due to zero or non-zero restmass stuff), the origin of mass is the gravitational interaction [not the Higgs process].

The Higgs is irrelevant to the Mach considerations. The Higgs is NOT the origin of mass-energy (as Wilczek has repeatedly pointed out). It is a process that confers RESTMASS on otherwise zero restmass particles. Those zero restmass particles, via m = E/c2, have mass if they have energy. The origin of mass is the question of the origin of mass-energy. Mach's principle does have something to say about that."
