What is the deepest hole anyone has ever drilled in the ground and how do we know positively for sure what’s at the center of the earth? Anyone ever been there? Seems like no matter how good we are at predicting what is there, it is still pure speculation isn’t it?..Don’t matter what we think is there… ie molten lava, solid metal or incredible heat…fact is…ain’t know body been there. If we have please set me straight.

Boy, don’t any of you people ever read the Weekly World News? The Russians drilled all the way to hell a few years ago - they could hear the cries of the damned rising up through the drill casing!
Can’t remember if that was before or after they discovered that a lot of the US Congresspersons were aliens.

You might want to look into what they’re up to at Lake Vostok in Antarctica. It’s not quite the same thing, since they’re only drilling through a whole bunch of ice instead of into the actual soft and gooey bits of the Earth, but I think it’s more interesting.
Basically, they’ve drilled down to a lake covered for millions of years in ice, and have found a bunch of microbial life. And you know how nothing gets scientists going like microbial life…
We can “see” what is in the center of the Earth the same way we can “see” the unborn baby in the womb with a sonogram. When an earthquake occurs or an underground nuclear blast is set off sound waves penetrate the earth and can be measured as they pass through the body of the planet. These waves work just like a sonogram scan of an unborn baby, it gives a crude but useful picture of the structures and composition of the Earth’s interior.
Sorry, I just felt like I was being ignored. It’s not often that I get to be 1st with a link that answers the OP’s question.
Now I’m embarrassed.

Hey, I went to each link just to make sure you didn’t change something, even though the link said the same thing and the browser said the same thing, I checked anyway.
Along the lines of this discussion, it is worthy to note the question: “What if one were to drill a hole through the earth (along a diameter)?”
Well, if one were to jump in said hole, one would oscillate back and forth in a simple harmonic motion-like fashion. Why? Applying Newton’s Universal Law of Gravitation, one can show that the law of gravity behaves differently inside the Earth. The pull is weaker and weaker until you pass the center where the pull is zero. Again, the pull increases as you move passed the center.
Inside the sphere, it can be shown that the pull between you and the earth is totally cancelled at the center…slightly cancelled when off-center but still below the surface.
The math I’ve been shown assumes the earth is a perfect sphere, and I believe it may even assume the earth has to be hollow, too.
(Don’t try digging in your backyard just to prove it, now!)

You are ignoring, of course, the effects of gravity on the atmosphere! As you approached the center of the earth flying through the hole, you would be going through ever thickening atmosphere, and possibly burn up or be stopped due to increasing wind resistance of the thickening atmosphere.

I’ne noted this in the past; you can post a link with the answer to the question, but that doesn’t do the trick when the board is full of non-clickers. I think what you need to do is post something like a one sentence summary and then say “to read more about it, click here (the bold being a url link).”
Besides, the EPA or DoD would get a court order to stop your project just prior to you having the pleasure of jumping in the hole! This is the big thanks you receive for your back-breaking effort! (You’d probably be too tired to jump in if you didn’t already lose interest in the midst of digging, anyway!)
