"We are the navel of the Earth" ... say the Australians .... but we know that this is not the alphabet ...
Many scientists are not being in the center of the Earth ... and exploring it on the surface with not very accurate sonar ... prove that there are tremendous pressures ... everything is in full swing ... hell (not heaven) ...
I have my own theory about the center ... If one of you was in the mine ... then you know that there is a higher temperature than on the surface and increases with depth (about temperature until the speech is just an interesting fact ...)) ) ...
If you take sensitive weights, weigh 100 g (not necessarily 100) on the surface and in the mine, then 100 g will weigh less under the Earth ... why so, ask? ...
Here the force of gravity of the Earth is distributed, as a result, the rock above you also attracts your 100 g ... than reduces their weight ...
Now imagine that you are descending lower and lower ... until you are in the very center of the Earth ... based on the previous fact and the assumption in the center of the earth - weightlessness (and the point ...) ...
That is why the Earth’s core is liquid and moves (since at high pressure any substance becomes solid and cannot flow or move) ...
On the bill ... and what is the temperature there ... and is hell really ... one can also assume no (hot temperatures) ... because the temperature is formed as a result of compression (pressure) in the middle layers of the Earth (crust, mantle). .. but in the very center of compression there is no (for weightlessness). ..
So ... and the temperature is low ... moreover ... the center of the Earth may be empty ... again as a result of gravity stretching the earth's matter and stretching it through the centrifugal forces of the planet's rotation ... (check and mat ... so who really needs to give the Nobel Prize ...)) ...
It’s also cool to drill dir across the Earth’s diameter ... so it’s possible to fall (and not fly for free) to America ... send them mail ... but that's another question ...
