Judy:
Well, to start with, I think I was confused as to
what you meant by "spinning." You mean spinning
*in place*, right? If so, isn't it the string it's
suspended by winding up and then unwinding that
causes the weight to stop spinning and change
direction?
Bronte:
The analogy isn't perfect, and I'm certainly not convinced the earth will
change rotation in 2012. It's just a theory. I came up with the analogy and
experiment simply from observing that an object at the end of a string rotates,
and the earth rotates. Certainly I'm not suggesting the earth is suspended on
some string. I suspect its rotation started from the force of its creation. But
it's possible that things that rotate resemble other things that rotate. Hence
my interest.
Judy:
Also, the earth's axis that it rotates around has a wobble,
like a top (actually several different wobbles),
which would have to mean whatever the equivalent
is of what the string is attached to moves around
in gigantic circles.
Bronte:
You can perform the same experiment with an object that wobbles (something
not symetrical hanging from the pendalum).
Judy:
Also, I don't think there's any scientific evidence
that the earth's rotation has ever reversed itself
in the past.
Bronte:
As I said before, there is evidence in ancient texts. I know of no scientific
evidence.
