obviously for the sake of life, better positioned than venus or mars.

okay, two questions.

1. how far can earth be placed further or closer to the sun while
still maintaing the existence of life, no matter how simple?


Find a copy of it was either Discover or SciAm about 6 months back. Some
scientists did some modelling of this question.


2. are we perhaps not perfectly postioned? would we better off if we
were placed a little closer or further away? do you think our
greenhouse problem will be alleviated if we move a little away from
the sun?
would we have better seasons and better crops if we were a bit closer
to the sun?

okay, now imagine a sci-fi scenario. can we build a device on earth
that takes us a little further away from or closer to the sun? let's
say a giant rocket launcher with the blasters facing against the sky.
so when we blast it, the earth moves in one or other direction? or is
this just ridiculous?

I heard that the earth get warmer the further the sun is from the earth
(summer) and colder the closer it gets. So if the sun fell on the earth we
would freeze to death?
