In GR, the speed of gravitational waves is _exactly equal_ to c.
- oneshtein 2y agoIn reality, speed of light is slightly lower than speed of gravitation, because gravitation slows down speed of light.
- hyperbrainer 2y agoWe were presumably talking about an ideal massless space [Minkowski] in which the speed of light in a vaccuum is considered -- that is what c is defined as.
