In GR, gravity is seen as property of the geometry of spacetime (curvature) as opposed to a force field. Does this theory extend to electromagnetics ,i.e. could EM be described as a property of spacetime, or is EM strictly dealing with fields? Do light waves and gravitational waves travel in the same medium (spacetime), or separate mediums? Do gravitational waves travel at c, and if so , do all fundamental force waves travel at c, or just light? Also, is there any correlation between the ranges of EM and G being infinite as opposed to weak/strong forces (see link: en.wikipedia.org/wiki/Fundamental_forces#Overview)? I have no background in physics so any help/corrections would be greatly appreciated. thank you.(adsbygoogle = window.adsbygoogle || []).push({});
