First its important to understand that this is the most profound disagreement in all of science in a century and a half and, even so, it is the tip of the iceberg, the ramifications of this disagreement will change everything we know in science, top to bottom.
To begin with basic stuff.
All science knows
The earth has two crusts. One the mostly basalt lower crust or the oceanic crust which is 2 4 miles deeper down than the higher upper continental crust. This lower crust, essentially covers the Earth. It this crust is being made daily at rift cracks that snake around the earths mid- oceans. But how could all these rifts continually spread apart without the Earth growing? Ah .that is the question .isnt it?
Sitting on or in and as part of the oceanic crust is the second higher upper crust or the Continental Crust rising for the most part out of the water. It is made mostly of granitic rock, which is 2.5 times the weight of water.
Some edge area of the Continental Crust or Plate dips into and under the sea level of the ocean. This area is what we call the Continental Shelf. So as you go out into the ocean and the water gets gradually deeper that is the Continental Shelf. At a given distance out into the ocean the ocean floor suddenly drops off and goes down like a plummet 2 ½ to 4 miles to the deep ocean floor, where we find the second lower crust, the Oceanic Crust made mostly of basalts which are 3.0 3.3 times the weight of water. So to make it visually clear, if you took the water away what you would see as you go out into the ocean a distance is, the Continental Shelf would suddenly drop away and down like a ridge in Arizona., except it would go straight down for two to three miles, as if it was suddenly broken off. The other side of that broken off ridge is across the ocean thousands of miles in Europe, or Africa and west to Australia and Asia.
How did the two sides of this higher crust spread apart?
Rifts or eruptive cracks in the ocean floor provide new material in the form of molten magmic rock that rises up at a rift area and the oceanic plate spreads apart and the two sides move away from each other smoothly and regularly, and so the continents welded within the oceanic plates also move apart as the ocean bottom spreads . Now if this happens and it does, all over the world, logically speaking, this Earth must grow.
We I argue that, that this outer crust originally covered the whole of a smaller Earth and the Earth sphere grew. The outer crust, therefore, had to crack and spread to accommodate a growing Earth which it apparently did.
We further argue that if you were to shrink the sphere of Earth
by letting the oceanic plate re-enter the rifts they erupted from, over time
the continental crust would easily and completely fit back together, and this solution satisfies all questions of tectonics, science, geology, paleontology, theoretical and practical physics, cosmology, and subatomic physics. Pretty simple actually.
Well, well. Another one who spent less than 60 seconds at the site. The author goes into great detail about the theory of subduction zones, but you'd have to cast off your pre-conceived notions and read a bit to discover it.
Say what you will, but what's at that site is irrefutable logic. I can't, and won't dismiss it.
continental drift it bunk?
But how could all these rifts continually spread apart without the Earth growing? Ah, that is the question, isnt it?
I stopped reading there.
During the recent quake in Japan, in some places there was as much as 150 feet of the Pacific plate that was shoved - and shoved hard - under the Asiatic plate.
From the author:
"Against this is the current Pangea theory which insists that the continents float willy, nilly about the Earth, spinning, sliding, bumping, and crashing like bumper cars in a carnival. (Thats a common description which some geologists are currently backing away from in small numbers.)"
and: An aside .you may fairly ask how this matter can be created. Its created at the plasma core of all planets, moons, and suns by a process that is so common that science has a name for it, pair production! Its how all matter is made from energy.
The mass of Earth is 5.9742 × 1021 metric tons. The mass of Mars is 6.4191 × 1020 metric tons. If the earth has grown by 5.33 x 1021 metric tons created by pair production that means there are 2.67 sextillion tons of antimatter which is somehow kept separate from 3.31 sextillion metric tons of matter. No wonder Obama hates drilling and fracking gas and oil wells. He is just trying to keep the matter and antimatter separate.
I can see how that could happen, given the force of the earthquake, though I don't see that it's incompatible with the author's base theory.
Only a mental midget would buy this. And no, I didn’t waste my time with the videos either.
So I guess the earth must be puffing up like a ballon then.
They'd better be careful when they drill new oil wells. They might pop the bubble and the earth would collapse back down to a sphere the size of the Moon.
I see you’re at least processing the guy’s theory with some degree of analysis, Karl. Appreciate you trying to keep it light-hearted.
In other words, "Don't confuse me with facts, my mind's already made up!"
I had a feeling when I posted this, that I’d be opening myself up to a lot of wisecracks, and that’s ok. I’ve got the hide for it ;-)
I just want to know, though...has anyone taken the time to watch the videos at the site? You can go through all fifteen of them in about half an hour, and trust me, they are compelling.
I understand, Chode. I had the same question, but I also understand that in a system as large as an entire planetary crust, there are going to be forces of all types exerted in various locales.
I don’t think it debunks the guy’s entire theory.
Good observation, though.
