You beat me to it! I was about to post a similar comment. Yet another Earth centric "picture", appears on Astronomy picture of the day!And, this is astronomical?

He says the North and South Atlantic Oceans will shrink due to subduction of the oceanic crust along the East coasts of North and South America. In fact the Atlantics are spreading, and there are no subduction zones on the East coasts of those continents.And, this is astronomical?
Rather, The Pacific is being subducted around much of it's rim, (Pacific ring of fire), and in the cases discussed here, the WEST coast of South America is subducting the Pacific giving rise to the Andes mountain range.
Which from the sciences turns out to be at best, speculative.Vulpine wrote:People really need to look at the broad view and collate all the data we have in a wide area of science to get an idea of where the world is going.

Thermodynamics don't work like that, I'm afraid. It doesn't deal with 'order' as we perceive it, but rather with the amount of 'useful' energy in a closed system. Thermodynamically speaking, a shuffled deck of cards is just as ordered as a deck of cards sorted by suit and value.Case wrote:Not hindered by in-depth knowledge of paleogeography,
isn't it more likely that the Earth's surface is stabilizing
thereby limiting how much tectonic plates will shift in the future?
It seems to me like the map is expecting shifts to keep going
until landmasses are re-aligned in a second unified big super continent.
While that would seem to give a nice sense of order,
it might violate the second law of thermodynamics;
things that break apart, usually don't realign by itself in the future.
All that shifting around costs energy,
which would position the plates to a more 'efficient' location,
until an equilibrium is achieved
where the plates don't move anymore.
I think that could very well happen long before a second alignment.
Pretty neat, quite convincing. It would be nice to address the reason for the growth, tho'. That seems to be missing from his presentation.andywyndom wrote:Check this link out. It appears to make more sense to me.

Supposedly space is expanding, not matter.It could lend credence to the expanding universe theory, "Everything expands exponentially."
