But that's when things get interesting :-) Arthur Clarke has written two
memorable short stories in which the inhabitants of the Sun are highly
complex arrangements of plasma, and David Brin has written a novel on
the same theme. But so far it's purely science fiction, and no-one knows
if it's possible.
