Hawking (1988: 89-90):
General relativity predicts that heavy objects that are moving will cause the emission of gravitational waves, ripples in the curvature of space that travel at the speed of light. These are similar to light waves, which are ripples of the electromagnetic field, but they are much harder to detect.

From the perspective of Systemic Functional Linguistic Theory, according to General Relativity, gravitational waves are propagations of a disturbance, relatively contracted space intervals and expanded time intervals, caused by the acceleration of a massive body.
On the other hand, from the perspective of Systemic Functional Linguistic Theory, according to Quantum Mechanics, the wave model of light reconstrues light as potential — measured as probability — whereas the particle model of light reconstrues light as instance. That is, the (crests of) ripples in the electromagnetic field represent peak probabilities of particle locations.
That is, whereas gravitational waves are instantial propagations of space-time variation, light waves quantify potential instantiations of matter-energy.
