Lyrics: Children of Space

Lifeforms on other planets will be even more varied
than they are on this planet. They will depend to a
large extent on the gravitational field on a planet
which has a much higher gravity than Earth - obviously
you couldn't have large animals - they'd be small and
squat and perhaps with many legs. On the other hand,
on planets with very low gravity you would have very
spindly, thin animals - very tall ones - and trees
perhaps hundreds of feet or hundreds of metres high
and maybe even kilometres high. The variations we will
find in space are almost infinite...
