A Christmas Tree, or not?

The Wiki page covers it pretty extensively, including numerous citations:

 

"The Earth's field has alternated between periods of normal polarity, in which the direction of the field was the same as the present direction, and reverse polarity, in which the field was the opposite. These periods are called chrons. The time spans of chrons are randomly distributed with most being between 0.1 and 1 million years with an average of 450,000 years. Most reversals are estimated to take between 1,000 and 10,000 years. The latest one, the Brunhes–Matuyama reversal, occurred 780,000 years ago. ..."

Adam and Eve was written sometime during the 60s and describes what supposedly took place in just a few short hours when earth was flipped 90 degrees from its normal orbital rotation, to its side. I know earth constantly rotate at a 1,000 per hour, but a 90 degree flip from that plane in just a couple hours or so??? That would be like flipping a fast spinning gyro 90 degrees from its normal rotational path. A thin and interesting book, but as I believe; written as science fiction.

No I watched the intro of the video then googled the Mayan calender thing myself and found all sorts of doom day prophecies ranging from the Earthquakes and rapture to black holes and gamma-ray bursts from Alcyone A.

IOW, you found all kinds of conspiracy theorist prophecies that claimed to be based on the Mayan calendar, not any actual Mayan prophecies of any doom day events.

 

I'll have to say one thing, the Mayan (calander) scenario has given me pause to think. But after reading a ton of transcripts relating to it, I can find nothing stating that the end of time is near, as we know it. However, a "flip flop" of earths axis' does makes a lot of sense to me. Many Pseudo-scientists are convinced that this has happened more than once in our past history. Do they have a clue? Is there enough research to make an affirmation of such a possibility? Is such a reversal possible? If so, what might be the cause of earth doing a 90 degree flip in just a few short hours? The book, Adam and Eve has a running discourse on how such an event may have happened, but nothing conclusive. Any ideas?

You're mixing up magnetic field reversals with physical reversals of Earth's axis. There have been a number of magnetic field changes through time. Movement of the Earth's iron core makes that possible. There has been no significant change of Earth's rotational axis in the time of man. That would require a physical impact from a foreign body like an asteroid.

Is it possible that a close "fly-by", by a powerful magnetic entity be enough to change earths orbital orientation by 90 Degs., yet; not destroy our path around the sun?

In the realm of speculation anything is possible. IMO any magnetic entity powerful enough to alter Earth's physical axis by disturbing its magnetic core would be gravitationally more significant than magnetically. Something like a neutron star flying by would have enough gravity to slingshot the Earth out of its orbit around our sun. I think you can safely file this Earth axis shifted tale in the bin with leprechauns and unicorns.

My question was posted strictly as a hypothetical, not a qualified affirmation or even a theory. Yet, you counter with what you believe to be conclusive proof of which you know only as hear-say. You use words like leprechaun and unicorn as if you know quite a bit about "Puff the Magic Dragon" though.

Yes, silly answers seem to be your strongest forte. But that's another story. Try this hypothetical and let me know what you think of it, since it is still for all intent and purpose, other than through a telescope; an unknown.

The following statement primarily engulfed the first paragraph and I don't recall gravity even being mentioned, did you?

 

If a magnetar flew past Earth within 100,000 miles, the intense magnetic field of the exotic object would destroy the data on every credit card on the planet.

Dude, I said all of that was bull.

 

I talked to someone who got a Masters in world history from the University of Madison in Wisconsin and he told me the Mayan Calender itself does not predict the "end" of the world, just the coming of a new one meaning the same as the coming of another day, and that the Mayans themselves said they had recorded 8 of these world changes but they world didn't end 8 times.

 

 

The destruction of Earth is a misinterpretation of the Mayan Calender. The Mayan calender doesn't even just point to destruction, it points to the turning of a new world in the same context as the coming of the next day. The Mayans had said they went through 8 of these world changes, but the world wasn't destroyed 8 times since they've been around. The Mayan calender just states there will be something different about the world, and so far it hasn't been some kind of world-ending prophecy. Perhaps the calender even ends because they thought they would go to some kind of heaven.

A few days prior to Christmas of this year, 2012; something of cataclismic proportion is supposed to happen concerning earths gravity. Supposedly "it", gravity will be reversed and everything will be cast into an eternal void. "WOW"! That scares hell to me since I'm going to be eighty come Dec.11. I have read tons of material on the subjest but am totally in the dark about it. Could someone please be informative? The below link is about all that I have to go on. "HELP"!

I don't know who the dude was narrating such an insight to our ignorance Moon, but it was fun listening to him. It was also a bit superflouris on my part to put the question out as I did. But isn't it funny just how gullible we are at times, believing the shit that we do? I was really trying to figure out doGs slant on things. Edited April 21, 2012 by rigney

I figured you'd like that one, it's been along time since I heard the old shit from shinola thing but to be honest my grandpa actually said shit from apple butter...

I like your Grandpa's philosophy better. Apple butter does smell better than shinola.

If a magnetar flew past Earth within 100,000 miles, the intense magnetic field of the exotic object would destroy the data on every credit card on the planet.

 

But a magnetar is a special type of Neutron star, and neutron stars mass between 1-2 solar masses. Believe me if a a solar mass passed within 100,000 miles of the Earth, wiped credit cards would be the least of our worries, As 100,000 miles is well within the Roche limit for that mass and the Earth would be pulled apart into rubble. Also, it should be noted that even a magnetic force strong enough to flip the magnetic poles will not effect the physical axis of the Earth, as the magnetic poles are physically tied to the Earth. In fact, it slowly migrates all the time. Here's an image that shows how the North magnetic pole has moved over the last ~400 yr.

I am aware of what a magnetar is and I'm not trying to be contrary, but how do you and doG possess all of this knowledge without any reference at all. i gave you reference! But am I to take your word as gospel rather than evidence that has justification through theory and research? Edited April 22, 2012 by rigney

Not to add to any pseudo science, or step into a heaping pile of shit or anything, but I feel compelled to share.

 

I had a weird dream last night. I was sitting in a cafe and was discussing world events and we were on the topic of physics. Whoever I was talking to started discussing the evolution of the state of accepted physics. He looked at me and said "they used to believe in Einstein's negative gravity, but now they believe in . . . " The thought stuck with me and so I just looked it up. It seems that there was something to the idea of negative gravity or a negative cosmological constant in Einstein's theories. I'm not sure where any of this is coming from or what it means, but I thought it was fitting to the conversation. No one massacre me k . . .

The most fasinating thing about science is, an accepted theory for today; is nothing more than a stepping stone into a more enlightened tomorrow. Without this constant advancement we would likely still be dragging sleds or pulling a travois around behind a dog team. Since I am neither educated in physics or any science, I can only read and try to understand. Nothing is etched in stone for me. Edited April 23, 2012 by rigney
