You can say whatever you wish and cook up whatever dynamicist
explanation you need to support the withdrawl of Pluto as a planet but
equally you have to acknowledge the equally good dynamicist explantion
which supported the discovery and naming of Pluto as a planet.
I look at the half-hearted attempts by astrophorographers to live with
the demotion of Pluto with great interest,not because of the merits of
celestial mechanics which is and always was a really dumb way to
explain planetary motion,bjut to see if they had enough intelligence to
watch you lot shoot yourselves hastily in the foot.
Obviously they do not have enough intelligence and there is nothing
that can be done about that.Dynamicists did not gain a victory,they
just highlighted how stupid they really are.
