I saw a program the other day which said that the planet Mars lost most of it's
atmosphere when it lost it's magnetic field. It said that the field deflected
harmful solar winds preventing them scouring away the atmosphere, but it lost
it's field when the planets core stopped rotating, this being the result of the
core cooling down and solidifying.
Their was a large thread on Lugnet discussing wether you could move a planet and
I was wondering could you melt the core core of a planet (and get it moving
again).
One way of melting the core would be to move it so close to the sun that the
whole planet melted and then move it back out again but I don't know what the
consequence's of this would be. Could a melted and then cooled planet sustain
life?
