I can tell! Just finished watching the expanding earth clip you posted in that other thread. A great work of fiction if I've ever seen one.
LOL.
Here is what the inventor of plate tectonics mythology had to say about your beloved hypothesis after he rejected it:
"Subduction exists only in the minds of its creators." -- S. Warren Carey, geologist, 1976
"People don't want to see it. They believe in subduction like a religion." -- S. Warren Carey, geologist, 1981
"Subduction is a myth." -- S. Warren Carey, geologist, 1988
And here is what contemporary scientists in the field have to say:
"Putting aside the insurmountable mechanical problems of subduction (a solid driven by the force of gravity penetrating into another solid), this is a gross violation of the obvious and of direct observation. Heat cannot be released instantly, because it is known from petrology that the cooling rate of rocks is about 50 degrees Kelvin per billion years!" -- Stavros T. Tassos, seismologist, 2005
"Therefore the thermally controlled conveyor-belt subduction model, as well as any variants or hybrid models, should be discarded because they are in fundamental contradiction with direct observation and deny the obvious." -- Stavros T. Tassos, seismologist, 2005
"In the oral session, except for one presentation that was clearly pro plate tectonics, and another one that did not address the issue of global and large scale geology specifically, there was general consensus that subduction, and therefore plate tectonics, is mechanically impossible." -- Stavros T. Tassos (seismologist) and Karsten M. Storetvedt (geophysicist), November 2007
