Too bad that you are wrong about permittivity and permeability of free
space being zero. Quantum "vacuum" charge = +,- sqrt(hbar*c) rules,
baby!
| | So, what ARE permittivity and permeability all about?
| |
| | Consider that the Maxwell equations:
| |
| | curl H - dD/dt = J
| | curl E + dB/dt = 0
| | div D = rho
| | div B = 0
|
| Where is mu0, epsilon0 in those equations?
Too bad that you snipped out the part that shows where they are. Read
Jackson 3rd ed. and Griffiths' "Intro. to Electrodynamics". Please.
| | contain 4 fields: E, D, B, and H,
|
| But there are only 3 fields, gravitism, electrism and magnecity,
LOL!
