	I discussed this with an astronomer friend of mine last night.
His comments amounted to saying that this is based on a very naive
model of planetary cooling, and that models exist which in fact are
consistant with the observed temperatures! Since there is such a
model, the cited temperatures are *not* evidence of young age. Thus
indeed they have not existed long enough to cool off, but they would
take much longer than the postulated age of the Solar System to do so.
In addition Jupiter and Saturn are still undergoing a small amount of
gravitational contraction.
