It wasn't a ridiculous thing to worry about at all.

  Yeah, I'm with the scientists on this. They had built the first bombs only a couple years after the first nuclear pile (a sustained nuclear chain reaction), and it was clear what they were trying to do was massively in excess of that. Taking a moment to make sure Earth didn't become a nuclear pile would be great. n.b. That first nuclear pile was in December 1942, which is way later than even I thought it was. This stuff was happening fast.

  didn't really mean it was ridiculous for them to think about, just that it seems so now in retrospect.
