I feel I'm getting myself into unfamiliar waters, but I thought that it
wasn't the amount of energy so much as the concentration of that energy in a
single point that would be needed to move the earth out of its orbit. Now
that's not very likely is it (that a significant proportion of the world's
nuclear arsenal would be detonated in the same place at the same time)?
The other stuff about destroying the atmosphere, I'll go along with though.
The 1950s UK sci-fi film 'The Day The Earth Caught Fire' (which is a lot of
fun BTW) has the premise (not unreasonable for many in those naive times)
that nuclear tests near the Earth's poles knocks the planet off it's axis,
and out of orbit sending it towards the Sun. The attempted resolution is to
detonate more bombs at the other pole to try and knock it back again. The
film doesn't end with a clear answer as to whether this has worked or not.
'When World's Collide' on the other hand, has a rogue planet flying towards
Earth, and causing all sorts of environmental disasters. The solution here
is to build a spaceship to take a small select group to the rogue planet,
and create a new life there, whilst everyone left on Earth gets killed.
Another fun 50s film, albeit extraordinarily ropey science.
Flash Gordon- the film from the 1980s anyway- seemed similarly to suggest
that 'Mongo' was a kind of rogue planet roaming the galaxy with Ming
attacking other world's at whim. Of course, I've been reading recently that
there's a view amongst astronomers that there may be many rogue planets not
orbiting stars, flying through space that may account for a lot of the
missing matter of the universe (since they don't give off light we can't
really see them at all).
Spot the S/F freak :-)
