Grand central station ping.
At the very teeny tiny itty bitty center there may be a MINIATURE black hole however.
Oh, have faith. Some of us are capable of having intelligent discussion.
BTW.....that last white spot is called Earth. De rest of it be Erf.
Meanwhile, on the other side of Erf, folks report a gentle warming sensation on the soles of their feet and a strange translucence that makes it seem one can see their foot bones right through their shoes.
I maintain that the pressure at the center of the earth is zero. Matter there is subject to a uniform force field generated by the uniform distribution of matter around it. When I've discussed this with geology professors on my occasional college visits, they have either been speechless or asked if I would be interested in writing a paper. (I'm not, and my credentials are minimal. I am a non-academic with math degrees.)

Good old planet earth.....the greatest thermos in the universe.
This doesn't make any sense to me. I'm not a geologist, but if it were that hot, then wouldn't it show that the earth would NOT burn up if it touched the surface of the sun? If it is already enduring such temps, then the sun shouldn't pose a big problem.
This may sound like a dumb question to any geophysicists out there, but if the temperature at the center of the Earth is so darned hot, why isn’t it the same for Mars - or the moon?
I mean, is the heat being produced by gravitational compression, or is there something else at work here?
From past discussions I've gathered, rightly or wrongly, that the moon is a factor. Lunar gravity affecting the liquid core as it does the oceans or some such.
You'll probably want to take that with a big grain pending further responses.
Compression produces part of the heat, but most of it is from radioactive decay of Uranium. The core is one bigazz fission reactor.
I never would have guessed either reply. Learn something every day. Thank you both.
So... I’m thinking that without all that uranium, we’d be as cold and dead as the moon?
The heat in the interior of the earth is thought to be produced by decay of radioactive elements.
The earth would not “burn up” if it touched the surface of the sun; it would vaporize. The earth is not destroyed by the high temperature in the core because there are thousands of miles of cooler material between the surface and the core, and because the extreme pressure in the core prevents vaporization.
When the geology professor asked if you would be interested in writing a paper on the subject, that was the equivalent of a nice southern grandma saying Why, bless your heart : ),
Actually, no.
Maybe you wouldn't understand as you seem prone to ignorant remarks.

Net gravity is near zero at the center, and low for most of the core. The pressure must be all heat generated.
I know earth is a good insulator, but after the amount of time the earth has been around, and given the vents we have (volcanoes, etc), if the core were really heating the planet to the temps suggested, we'd never have winter, or polar ice caps.
Don't get me wrong, I know the core is warmer than the surface, but to those temps?
