Who claims this to be the case?Chronos said:T It seems counterintuitive that pemittivity and permeabilty also constrain the speed of gravity since neither electric or magnetic fields appear to have any influence on gravitational fields.

Permittivity is a measure of a material's ability to store an electric field. It is represented by the Greek letter epsilon (ε) and is measured in units of farads per meter (F/m).
Permeability is a measure of a material's ability to support the formation of a magnetic field. It is represented by the Greek letter mu (μ) and is measured in units of henries per meter (H/m).
Permittivity and permeability are both properties of a material that determine its response to electric and magnetic fields, respectively. They are related to each other through the speed of light in a vacuum, as described by the equation c = 1/√(εμ), where c is the speed of light, ε is permittivity, and μ is permeability.
Permittivity and permeability determine the speed at which electromagnetic waves propagate through a material, as well as how those waves are affected by the material. Different materials have different permittivity and permeability values, which can greatly impact the behavior of electromagnetic waves traveling through them.
Gravity is not directly related to electromagnetism. However, Einstein's theory of general relativity describes gravity as a curvature of spacetime caused by the presence of mass and energy. This means that gravity can indirectly impact the behavior of electromagnetic waves, such as through gravitational lensing, where the path of light is bent by a massive object's gravitational field.
