I also have a second question above G-waves themselves. They appear to be propagating waves of contracting and expanding spacetime. When spacetime contracts at the leading edge of the wave and then expands, does the expansion revert back to normal spacetime flatness or is there a momentary...
At 0:51 in this simulation video there seems to be a brief moment upon merging that these singularities produce what appears to be negative gravitational "Spike?" that seems to bulge spacetime in an opposite metric compared to normal spacetime flatness. Is this a quirk of the simulation or is...
