Could they tell that from a big ol' nuke? Great is the power of prayer.

Yes, they could. Metor's don't leave a radioactive crater, and no one in the world has that big a nuke anyway.

Now you could just drop a big rock (asteroid) on them, but we aren't quite up to doing that either, although the theoretical aspects are solid.

Just as long as *we* are the ones doing it, and it's not followed by pygmy elephants in pink platform shoes raining down from the sky in hang gliders. :) ("See Niven and Pournelle's, "Footfall"

LOL. How did you find that post? Did you see the date on it?

I knew we could tell, but could they? Radioactive asteroid? Put a good dose of iridium in the nuke for conversational purposes.

So we don't have a nuke big enough. My mother always told me to make do with what you've got. ;)
