"Lloyd Parker"
Most scientific theories hold up quite nicely -- quantum mechanics,
relativity, evolution, plate tectonics, black holes, etc. Please tell uis
all these scientific theories that have been overturned recently.

In the current context it might be pedantic to point out that all the
theories you quote have 'exotic' or alternative models proposed,many in the
peer reviewed literature-
Quantum Mechanics-plethora of interpretations including 'Many
Worlds',Hidden Variables etc.
Special Relativity-eg Aether theories , results of Michelson Morley
Experiment and modern equivalents questioned to this day.
Evolution-Creationism,'Punctuated Equilibrium'.
Plate Tectonics-Expanding Earth,Plate Driven Tectonics Vs Plume Driven .
(In theory of the core-the nuclear reactor
model)
Black Holes-Gravstars,Condensate Stars.

If you read New Scientist you'll find an almost weekly diet of such 'left
field' stuff.It would seem that healthy mainstream theories always attract
alternative ideas,some with more credibility than others.Is it a sign of the
vitality and relevance of canonical theories that they attract or leave
room for alternatives?

Also by concentrating on Corbyn the thread seems to ignore other work going
on in the field of Solar-Geomagnetism-Weather-Climate.For a recent snapshot
of research in the peer reviewed literature see-
