- You don't bomb the comet. You set off a fusion explosion a couple of km away
- (maybe even more) to melt the skin on one side and produce a sudden burst of
- outgassing. This might cause the comet to calve, though probably no large pieces
- would still be on impact trajectories. If one was, repeat as needed.
