The earth’s core (split from Does our moon affect Earth's core)

[Luzephyr]

Possibly. But we know nothing about the earth's core. Therefore it would be impossible in our present state of knowledge to know what effect if any the moon might exert upon the earth's core. Any answer we might come up with to this question is purely speculative.

By 'we', do you mean you ?

[Luzephyr]

Perhaps you could name something known about the nature of the earth's core, and tell me how that knowledge was got, by what means it was verified, and by whom. Speculative ideas however sophisticated are not synonymous with scientific knowledge. Surely we must have real knowledge, not conjecture, about the earth's core, before we can begin to speculate, on the basis of such understanding, about the influence which the moon might theoretically exert upon it. Otherwise we are making wild conjectures on the basis of things which are themselves speculative in nature, an activity quite divorced from reality however stimulating to the intellectual imagination.

There is plenty of information about this on the internet, if you are genuinely interested (which I am not convinced you are, since if you were you would already have read it). There is no reason for people here to duplicate it. I suggest you read the portion of this Wiki article that relates to the Earth's core first: https://en.wikipedia.org/wiki/Structure_of_Earth#Core , and then revert with any specific issues you may want to discuss.

Don't you think these are rather adversarial ?

 

I agree that stone age Man knew nothing about the core of the Earth.

But serious work began in the rennaisance with studies of gravity.

Later work by that reclusive genius Cavendish was able to establish that it must be made of something very dense by careful gravitational measurement.

The late 19th century brought new tools to bear with the beginnings of seismology by Ernst yon Rebeur-Pasebwitz, techniques that have continued to develop ever since.

Current work in Canada, Sweden, Antarica, out in space and elsewhere continues to probe the working of the core via the Earth's magnetosphere, which can only be generated in the core.
A good book to read here is 'Aurora' by physicist, Melanie Windrush who specialises in this stuff.

Again I'm at a loss to understand your meaning.

Do you mean 'Has anybody touched it or seen it ?' then , of course not.
But science is causal, and hings can be inferred by he effects they have on other hings.
Science does not simply rely on the 5 primary senses; mostly it relies on your brain to recognize causal sructures that tell us how nature behaves.

IOW start living and learning beyond your fingertips

Our knowledge of the Earth's core comes mainly from the patterns in the traveling of seismic waves. For instance, scientists know that the outer core is liquid because the S waves do not propagate. Shear waves do not propagate in liquid.
