And Now: Supercontinents

By November 11, 2013

Follow me on:

Did you enjoy doing the Micro Geology Quiz yesterday? (See the post just below.) Now it's time to step way, way back and look at one of the biggest things on Earth, in my new article on supercontinents. These are what happens when the wandering continents, and various smaller bits of continental crust, happen to glom together in one big landmass. Supercontinents appear to have formed four times in Earth history, and another one appears to be coming up starting in about 50 million years.

Some people wonder if such a thing would knock Earth off balance, but it wouldn't, for the same reason that melting icebergs don't change the sea level—the simple physics of buoyancy sees to that. The question we don't have a perfect answer for yet is what supercontinents do to the circulation of the mantle underneath them. It is clear, though, that supercontinents aren't any more stable than other plate-tectonic arrangements, because they have always broken apart after a while.

Have you ever tried to see if the moons surface matches the earth’s surface? Let me recommend a location for you. The lunar south pole over Greenland, make sure you put Schrodinger right at the curve of Greenland. That’s where the weather always shows it’s print. Of course this means you will have to make the moon bigger, so do it! Now if you keep this size consistently, you will see that every side and large crater on the moon are from impacts with the earth. If you try what I say, there is noway you will not see the same thing. During the floods in Colorado, if you look back at the weather pattern from the radar, you will see a perfect print of the Schrodinger crater, at the same size, absolutely perfect, and undeniable. I’m just saying that you cannot leave this part out, it’s what creates the continents, and what breaks them apart. It is the missing link, guaranteed 100% Do the research. Geologists have to know this, there is noway they don’t, no way?

As a matter of fact, as my research shows that there are at least four different areas on the moon that had hit the same place on the earth as the super continent. It eventually broke the super continent apart, changing the impact patterns on both the earth, and the moon completely. If you look there is no way you will see differently, it’s that clear.

So what we have is the lunar south pole, impacting with the earth’s north pole? What this tells me is that there is a magnetic attraction. You can easily see that the lunar south pole has impacted Greenland. It would take anyone about 5 minutes to see it. Reverse the moon’s south pole, put Schrodinger at the curve by Iceland, and you will clearly see it’s a perfect fit. Now I know much more than I did the last time I commented on one of your articles. Since then I have learned that the Schrodinger crater is the key, Mare Oriental too, but Schrodinger is easier to spot. It’s print ends up in so many places on the earth it almost makes it difficult to believe. Watch the weather at the curve of Greenland for a 1100 miles in diameter circular pattern, also around Colorado. I have a picture saved from the flood weather, the radar return, if you were to see it overlaid over Schrodinger crater you would know, you probably already checked it out. I have gotten past the conspiracy part, now I am trying to find the answers, which I believe I already have?

I have a serious super continent question. I look at the globe every day using Google Earth. I pay close attention to weather patterns, the shapes of land features, and have even put together my own versions of super continents. When you look at the curve of the Himalayas, and shape of the Tibetan Plateau, it is exactly the same shape, and size as the eastern half of the Australian continent. When you overlay one over the other they show the same or very similar land features. How does this take place on the earth? Where they created in the same place at different times, possibly in layers, then separated later? I have seen the shape of Australia in the weather just south of the Himalayas, when you see these weather patterns it’s showing former locations of continents. I see this quite often, the weather shows us the many ways the continents were arranged. Like the weather down by Antarctica, shows that it was weather in the Sahara at one time. I find it very interesting just what the weather can actually tell us about the history of the earth. Everyday it will show the moons true size with near perfection, and shows where these impacts have taken place, with total consistency in size, and location. Schrodinger crater on the moon is 200 miles in diameter, on the earth it’s prints are always 1100 in diameter. Whenever you see a weather pattern that is almost a perfect circle at about 1100 miles in diameter, that is Schrodinger, guaranteed. Here is another neat thing that I discovered. Take any picture of any hurricane, typhoon, or cyclone, and overlay into a reversed image of Schrodinger. Every one of these storms is shaped by a print on the earth made by Schrodinger, no lie! Every storm is shaped exactly like the features you will see in Schrodinger, the eye and everything.

David, I have no answer for your question. Neither do I want to discourage your project and the pleasure it obviously gives you. There are free blogging sites out there that can give you a much better outlet, including the ability to post images, than a set of comments on the About.com Geology blog.
