I listened to one of NDT's lectures on a podcast this morning and he made a passing reference to two black holes orbiting each other that would eventually "spiral into each other due to orbital erosion" (his words)
I'm familiar with orbital decay for satellites in orbit around the Earth due to friction, emf etc; and I'm familiar with planet and moon orbits expanding from tidal forces, energy lost to gravitational waves etc. However I'm struggling to understand Neil's reference to orbital erosion in relation to Black holes (although from the context of his comment I don't think his comments were specific to Black holes), my understanding until now has been that two bodies orbiting each other would be stable unless other forces act inn them?
Can anyone enlighten me as to what Neil may have been referring to?
Thanks
Matt
