: : : : No they do not. In general relativity local space-time is always flat and therefore by definition the properties of space-time do not change.
: : understood... however, how are the constants : : of permeability and permitivity derived from : : space, other than just measuring vacuum as a constant.
: : What makes the constant of P/P what they are? : : What are they directly corrolated to?
: : The mass density of the cosmos, perhaps?
: Isn't P/P dependant on the speed of light? : I believe:
: Permittivity constant= 1/(speed of light squared x permeability constant)
right, it is the reciprocal of the velocity of light, but my question could be also stated as the following:
what then causes the speed of light to be what it is?
likewise: what causes the permitivity constant to be what it is?
Is it related to the mass density of the cosmos?
