Sorry if this is not the appropriate section, and also thanks very much for this board, I've been reading off here for awhile now, finally signed up to ask this question.
I assumed, based on some half-remembered expert testimony, that a large enough nuclear explosion could disrupt the Earth's orbit.
Now that I consider the monstrous velocities and masses involved, I tend to doubt that's true. I haven't been able to find an article addressing this anywhere, which perhaps means it's not a valid concern.
Can anyone point me towards an answer?
