Earth may have two cores

VERY NICE POST.

When a new set of facts requires the creation of a new theory the process is far from the orderly picture often presented in books. Many hypothses are proposed, studied, rejected. Researchers discuss their validity (sometimes quite heatedly) proposing experiments which will determine the validity of one or the other, exposing flaws in their least favorite ones, etc. Yet, even when the unfit hypotheses are discarded, several options may remain, in some cases making the exact same predictions, but having very different underlying assumptions. In order to choose among these possible theories a very useful tool is what is called Ockham's razor.
Ockham's Razor is the principle proposed by William of Ockham in the fourteenth century: ``Pluralitas non est ponenda sine neccesitate'', which translates as ``entities should not be multiplied unnecessarily''.

In many cases this is interpreted as ``keep it simple'', but in reality the Razor has a more subtle and interesting meaning. Suppose that you have two competing theories which describe the same system, if these theories have different predictions than it is a relatively simple matter to find which one is better: one does experiments with the required sensitivity and determines which one give the most accurate predictions. For example, in Copernicus' theory of the solar system the planets move in circles around the sun, in Kepler's theory they move in ellipses. By measuring carefully the path of the planets it was determined that they move on ellipses, and Copernicus' theory was then replaced by Kepler's.

Stop getting technical mang

Agartha

goes to show, we know nothing.

Does this have anything to do with the woman that has two cores? http://current.com/items/89689638/woman_discovers_she_has_two_wombs.htm

Imagine if this second core was not really a second core. it's another Earth in miniature. the outer core is a boundary between the two acting as their sky. CRAZY HU?

we are so young and have so much to learn...don't rule anything out just yet.... give it a few billion years of scientific records and make conclusions then....

hope someone records histories of epochs accurately enough to decipher.........

Does the dual core help it process faster?

I remember learning in high school biology that there was an inner and outer core.......

Maybe this is some kind of unborn twin phenomenon???

The do have a tool to get at the material, but in order to assess the properties as they stand in the core, they need to use a simulated environment in which to examine them. The specimens change as they make their way to the top. Simulated environments are in development from what I understand. One uses diamonds to create the intense pressure of the core.

It was speculated a while ago that a Mars sized object hit the earth and was the cause of the earths polar tilt, 23.5 degrees...unusual for a planet. If the impact did occur, it's likely that there's more than the tilt to account for it. The core is very difficult to study. There may even be three oceans worth of water there stuck in the form of chemical lattices that are able to withstand the heat.

Vern???

1 core, 2 cores, 50 cores, whats the diffirence....? it's funking hot down there

Of course an announcement such as this is exciting. It introduces other possibilities. Like so much of science and "discoveries" some "ideas" cannot be proven or backed up after they make these assumptions. I'll get really excited when they can actually prove things.

maybe the Earth's core is dividing like cells, soon it'll have 4 cores.

If we take a step back from conventional geography, physics,chemistry, and consider the possibility of naturally occurring monatomic metals. Then we could accept that a purer form of all metals could exist. Instead of coming up with something that sounds implausible that is effecting our magnetic field, or why earth is so sensitive to solar radiation and other unseen cosmic waves. Intense energy and gravity, like what is found in the center of the earth, could entice the creation of crystalline metals. Who is to say what we could come up with if we were to say our molten iron core is actually a solid iron crystal? We already know the technological impacts of such valuable crystals. Although not metal look what quartz has done to the world.

kinda reminds me of that anima flick final fantisy the ghost within

Weird.

It's funny. For all we've learned, the Earth's interior is one of the most hostile places to study, and therefore we still know little about it. The core could be made out of peppermint candy for all we know.

Right now Zecharia Sitchen is one more step closer to being THE authority on Human history!

Very interesting, might explain a few enigmas surrounding the eletromagnetic field, great post.
