I came to wonder about something.Supposedly, mass is a property which is given to particles by a scalar field called the Higgs field. Mass, in turn, is responsible for gravitational fields.Could a similar analogy be drawn with electromagnetic fields? Electromagnetic fields are generated by a property of particles we call charge. Would there be a scalar field that gives electric charge to particles in a similar way that the Higgs field gives mass to particles?
Yor_on, you're right. Inertial mass and gravitational mass are different concepts. The Higgs field only explains inertial mass. For all objects we've tested, it appears that inertial and gravitational mass are the same. Indeed, general relativity relies on that as a postulate. But so far as I know, there's no explanation of why they have to be the same aside from the fact that they seem to be for all cases we've checked.
Mr. Data, there's probably only a few people on the forum who can understand those equations without a lot more explanation. Would you be able to explain it a bit more thoroughly in words for those who haven't studied tensor calculus and general relativity?
Hm, think I've seen this before?Yep, I have, with a explanation.Check out Green Destiny.
