Don (and sci.geo.geology learning community):
Thanks for the reply (and quite a reply it is). You must've put a fair
bit of energy into it. The tree of responses (postings) going back to
the original posting is considerable - and I was getting bogged down
playing catch up - so I do appreciate you stating your position. I'm
going to start to participate by considering what you wrote in reply to
my earlier posting. It seems that my first assessment of your position
was not too far off. I see two scientific questions that are embedded
among lines of your reply. I also see a lot of something else (e.g.,
those dumb guys, those bad scientists, those... - you know the stuff
that I'm referring to) that I personally think detracts from any
science that you are advocating. I saw comments of the same vein in
the postings of others. I would like to suggest that we refrain from
going there. I would like to try to directly lay out the two
scientific questions that I recognize in your reply (and in the earlier
postings of the group) - and give the group the opportunity to respond
openly and fresh.
Question #1: Is the Earth capable of very significant expansion?
Question #2: Is there subduction and destruction of lithosphere (crust
and rigid uppermost mantle) at convergent plate boundaries.
I assume that we are all students of the scientific method, a good
club. As such, one asks an 'open' ques, collects data (evidence)
pertinent to the ques., analyzes the data, hopefully makes logical
interpretations, and then states a best conclusion. If the group is
agreeable and reading this, lets see if we can post the evidence that
addresses these questions. The evidence is the key to all this. I
suggest one caution: not to mix the hard data you can offer and the
interpretations so closely that the reader can't separate one from the
other.
If there are no issues about this - - - Ready, set, go..........
Cheers,
Bob
