Re: A frightening thought . . .
What if -- just what if -- this technology was actually implemented?
What if it actually works -- not just the first time, but several times?
What if a new composite asteroid shows up where this does not work, but this technology is already holding all of our eggs -- and we have no workable backup?
The spacecraft would then push the bag against the asteroid.
This, in itself, is iffy enough for me,
Dan (given a ship that could carry the required fuel to move the mass of a 500 meter asteroid, though, this still might work)
