“And submarines were a popular mode of transportation for the German military at the time.”
“Anyway,” George went on, “A deep sea underwater submersible called Alvin, -not the chipmunk, (a reference that was lost to Oliver) that had been developed at the time, was used to search the ocean floor for submarines, gold, art work, and of course Hitler’s body.”
“Were your leaders so in fear of this man that they thought it necessary to search for his body on the bottom of the ocean floor?” asked Oliver.
“No, we had already won the war. He was a war criminal. In any event, they never found his body. But what they did find was a huge volcanic vent that went across the whole of the Atlantic Ocean floor, going north and south.”
“I know of what you are talking about,” said Oliver.
George did not bother to question that statement, he was sure that the grey creature spoke the truth. “As I was saying, they found this volcanic vent, now known as the Mid-Atlantic ridge. It was discovered that as the magma came up and solidified, it was pushing the ocean floor east and west, underneath the American and African continents. What they did then, -which is also I guess how it was found out about the earth shifting on its axis, every so many thousands of years or so, was to simply take core samples.”
“You see, when the molten rock comes up out of the vent, the cool ocean water solidifies it. This happens pretty fast and it gives the ions in the rock a magnetic polarity as it’s frozen in place. And of course, this rock became the new ocean floor.”
“So what they did was take some of these core samples, going east and west from the ridge, at something like fifty yard increments for about a quarter mile each way.”
“I guess what was found, was that the core samples taken at say the one hundred yard mark, and then the two hundred yard mark, going both east and west had a magnetic north polarity. Which is to be expected, right? After all, the North Pole is the North Pole…”
“Then, to everyone’s surprise, at say the third or fourth hundred yard mark, the core sample there had a south magnetic polarity. And that south-pole reading was the same on both sides of the ridge, at equal distances from the volcanic vent. All other core samples were magnetic north. So here’s all these north magnetic polarity readings, but smack-dab in the middle of these readings comes along a south polarity reading.”
“That’s very interesting,” Oliver observed, thoughtful.
Oliver told George, “Your solar systems rotation, or orbit, around the galaxy comes to around twenty-six thousand or so odd years. When your system completes that orbit, the planet goes through what is called a precession of the equinox. It wobbles on its axis just a little, that’s why there have been several ‘north poles’ or polar reversals, most of them in the same geographical area.”
Changing the subject again, George asked, “Aren’t you afraid that the tribes here will rebel? I am surprised that you guys get along so well, I mean being from different worlds and all.”
Oliver said, “We’ve been here a very long time. The natives of this world have never known anything else. We co-exist so well because the humans here don’t even realize that we are ‘Aliens’. We also made sure most forms of combustion were never part of the human’s lives in this world.”
“What are you guys going to do with me?” George asked, thinking that there still might be a way out of this. The alien had after all caught him spying on the morbid dinner party, and had helped him get out of there. He could have done the reverse and turned him in.
Oliver ignored the question. Instead he asked one of his own.
