The gravitational field outside the sphere can be accurately simulated by combining a series of simple equations called a spherical harmonic expansion. But does this still hold true for the field ...

Nonlinear effects associated with the vacuum should be important if the field strength is comparable to mec2 / eλe, where λe is the electron Compton wavelength.

Abstract A conserved stress energy tensor for weak field gravitational waves propagating in vacuum is derived directly from the linearized general relativistic wave equation alone, for an arbitrary ...
