Wouldn't the black hole's horizon also shrink past a planet orbiting it as it loses mass?

- simonh 9y agoI don’t think it makes physical sense to talk about planets orbiting inside the event horizon. Black holes only shrink due to emitting Hawking radiation from the perspective of our frame of reference at a distance. We can consider the contents of the black hole to be undifferentiated mass/energy. From the perspective of a planet in that situation, that’s kind of meaningless as the process would take infinite subjective time.
- bArray 9y agoWell, near infinite time is ideal if you're trying to survive the death of the known Universe?
