Hello.
I've red this thread and I saw some difficulties on explaining either the Earth is expanding or not. Maybe I could say, "yes" and "no".
"Yes." It almost convinced me that the Earth is expanding.
Take the case of Pangaea. India, Madagascar, Africa, and Australia did fit. Africa and South America did fit, and the evidences of Australia fits with South America, and both "ends" of North America and Asia, have been proven. If Earth did not expanded, then one of the evidences I mentioned above is not true.
"But, no."
The Earth may not be expanding because of what we call "Subduction." Convection currents may be false if the Earth was expanding. However, there is one hidden question that we didn't notice earlier.
Compare the rates of EVERY plate, or most of the plates. Compare the rates of divergent, convergent, and subduction rates. It may give you the answer if the Earth is expanding or not.
Or, maybe we could merge the ideas.
If Earth was taken as a model of a balloon, the rate of expansion of the balloon has a limit, so that it would not explode, thus giving the result of "the Earth wasn't expanding [anymore]," or at least the rate of subduction created by convection currents is maybe constant, or the rate of convection currents were increasing at a small rate [and it may give a limit, too], thus we could say that the Earth wasn't expanding.
Oh. I remember. What is subduction again? The oceanic plate shrinks when collided with continental plate, because the oceanic plate is denser than the continental plate.
The oceanic plate did subducted to a continental plate, and not for two continental plates.
The theory of earth expansion did follows the "rules" with subduction, and therefore earth expansion did proven. However, if you still deny the earth was indeed expanded, give some evidences that the earth did not expanded.
Just think twice, or even thrice, or many times. Like Newton, he had merged two opposite ideas so that he could make new formula, and he did not expect that from merging two different ideas to form another formula will prove that the heliocentric view of Universe is much true.
The change of thoughts is up to a person, whether he/she accept it or deny it. Do not force people to change their view by saying "bad" words, or by "shouting." Better yet, give them clues or ideas relevant to your view, and let them realize what is true for him/her.
If someone challenged other that he/she can prove the moon is bouncing, then you shall provide evidences that what you are trying to prove is true, and not by saying false arguments, like, "if the earth is expanding, the moon is bouncing," or something like that.
That's all for now. Thank you for the ideas and arguments.

Strawman. Actually 2 persons possess it.
