Life outside Earth - we could
have a problem
I can't remember if I read about this idea somewhere or it's
just something that my brain compiled from other information,
but I was thinking about life on other planets when I realised
that there might be a problem.
There was a TV program a couple of years ago which said that
Jupiter acted like a giant spounge which essentially protected
the inner planets from direct hits by attracting and swallowing
space debris using it's massive gravity. This has probably
protected us from pottentially millions of small impacts and
quite possibly a lot of large ones.
Now if this was what allowed life on Earth to exist and grow
through the rather violant stages of the relatively early
Solar System - would this also be a key if creating life on
another planet in another solar system?
In otherwords, would the existance of life not only require
the right conditions and elements like amino-acids, but also
a big gas giant which would rather narrow down the chances
of life, never mind intellegent life considerably?
I'm not saying that it doesn't exist especially when you
consider the size of the Universe and since the outer parts
are much more settled, this would pose less of a problem,
but could still pose the occasional hickup.
Back to mad theories....
