Gravitational fields, like electromagnetic fields, propagate at the speed of light. In Maxwell’s equations, the material equations (Sect. 4.1.4) include the two constants µ0 for permeability and ε0 for permittivity. Taken together, these constants yield the speed of light in vacuum.

摘要

Gravitational fields, like electromagnetic fields, propagate at the speed of light. In Maxwell’s equations, the material equations (Sect. 4.1.4) include the two constants µ0 for permeability and ε0 for permittivity. Taken together, these constants yield the speed of light in vacuum.
