A physical gravitational wave, therefore, cannot be represented by a solution to a linear wave equation. Relying on this property, the second-order solution describing such physical waves is obtained. The effects they produce on free particles are found to consist of nonlinear oscillations along the direction of propagation.549-563engGravitational wavesNonlinear gravitational wavesArtigo10.1007/s10773-009-0236-2WOS:000274904000012Acesso restrito1599966126072450
