The 3D problem, which we are now concentrating on, uses the G Code . Not only is this an interesting physics problem, but it is also a testbed of 3D spacetimes. We have made great strides in these 3D evolutions. It also can be used as a source of gravitational waves. That is, perturbed stars lose mass by scalar radiation.
Nonspherical perturbations result in gravitational waves.
Evolving two three-dimensional scalar field configurations and studying their inspiral coalescence could have great astrophysical implications because the gravitational waves emitted may not sensitively depend on the internal structure of the compact objects.
