- groone, on 04/12/2008, -2/+15There is a whole world in the center of the earth, filled with dinosaurs and cavemen and large diamonds and mushrooms. Everything in the center of the earth is larger than the stuff on the top side. I think it is the glow of the core to which the cavemen use as the sun and have termed Aklaka, the God of the Center of the Earth Sun. I think, but I'm not sure, that the Dinosaurs in the center of the earth speak and live in communities to which they cohabitate with the cavemen in perfectly formed brick cities with roman style aquaducts and running water.
- mbauer14, on 04/12/2008, -0/+10very interesting article. always amazing to realize we know almost nothing about the center of our planet.
- defaultfilter, on 04/12/2008, -0/+8If you jumped into a hole through the center of the Earth, how long would it take you to reach the other side?
Take a guess before you peek at the answer.

- cambob76, on 04/12/2008, -0/+6You would not reach the other side because you would be horribly burnt to a crisp.
- adml_shake, on 04/12/2008, -0/+4And so, the war for the oil reserves of the Mole Men begins....

- whodathunk, on 04/12/2008, -0/+3The same place where all that unobtanium comes from...
- mrjohnnycake, on 04/12/2008, -1/+4A poorly done documentary questioning accepted science!? I'm sold!
- defaultfilter, on 04/12/2008, -0/+3The question was meant as an hypothetical exercise in physics. Physicists often ignore all those little annoying distractions in reality and work in "ideal" conditions. In this case, ideal = "assume the Earth to be of uniform density and neglect air friction and the high temperature of this trip and the gravitational effects of nearby celestial bodies and etc....".
- trogdor282, on 04/12/2008, -1/+4ALL motion is perpetual in the absence of friction. But thanks to air resistance you would come up a few miles short even on the first oscillation. You'd have a lot of climbing to do.
- trogdor282, on 04/12/2008, -0/+3You're forgetting air resistance. The answer is 'never'.
- enderu, on 04/12/2008, -0/+3Nah, this is pretty standard science: assume the least complicated system that is supported by empirical evidence. If new evidence pops up, time to change the theory.
Lots of people would be surprised there are still plenty of things we don't know about how the inside of the Earth works. Plate tectonics, now considered fundamental to geology, was being debated just 50 years ago. - jweatherley, on 04/12/2008, -0/+2No. The gravitaional force would actually be reducing as you fell towards the centre. The mass above you starts to cancel out the mass still below you.
- spect3r, on 04/12/2008, -0/+2Bill Bryson said it well:
"The distance from the surface of Earth to the center is 3,959 miles, which isn't so very far. It has been calculated that if you sunk a well to the center and dropped a brick into it, it would take only forty-five minutes for it to hit the bottom... Our own attempts to penetrate toward the middle have been modest indeed. One or two South African gold mines reach to a depth of two miles, but most mines on Earth go no more than about a quarter of a mile beneath the surface. If the planet were an apple, we wouldn't yet have broken through the skin." - inactive, on 04/12/2008, -0/+2wouldn't gravity pull you back the other way once you got through? Would it be a perpetual motion machine, going back and forth like a ping pong ball, or would you eventually stall out in the middle?
- Sludgehammer, on 04/12/2008, -0/+2Maybe not by gravity, but if the hole had air in it wouldn't you be crushed by the atmospheric pressure?
- hillkiwi, on 04/12/2008, -0/+2Great, I'll mail you the registration forms.

I'm not saying I buy it, but it is interesting. - mrjohnnycake, on 04/12/2008, -0/+2Dear scientists,
I already knew this stuff. It was presented in an excellently done, very thought out movie called The Core. Why do we even need to do anymore studies? And on top of that, probably because they want to get this information to as many people as possible, you can find the movie on the cheap shelf at any major retailer. Come on scientists! Get a TV! Mine's taught me everything about the world and I didn't have to even do any mathematical equations or even use so called "reasoning". On that point, the only reasoning you ever need is to decide what to watch when movies like The Core are being shown at the same times as other quality, scientific movies such as Armageddon.
Sincerely,
The American Public. - inactive, on 04/13/2008, -0/+1You're right, but let's consider it a air conditioned pipe with no resistance. I should have stated all that so people would realize I wasn't suggesting that we really dig a hole to China, it was meant to be hypothetical. Wanna start some real arguments? Say you'd get burnt when you passed through the biblical hell.
- defaultfilter, on 04/12/2008, -0/+1Theoretically, under "ideal" conditions you would oscillate with the same amplitude and frequency forever. But as soon as you try to harness any of the kinetic energy, you would decelerate and eventually 'stall out in the middle'.
- cnldelta, on 04/12/2008, -1/+2Where cam I buy that Osmium thats supposedly rarer (and therefore more valuable) than Platinum?
- KTO3TO, on 04/12/2008, -0/+1so basically my geologic history class is obsolete?
- ISmokesDaPot420, on 04/12/2008, -1/+2Geology ftw?

- inactive, on 04/12/2008, -0/+1neat!
Ride of the Valkyries - codechino, on 04/12/2008, -0/+1"Jonathan Snow, assistant professor of geosciences at UH, led a team of researchers in a North Pole expedition..."
What's he doing leaving the Wall unattended? - Stonekeeper, on 04/13/2008, -0/+1rick wakeman ftw!
gimme a break, it was a great album... - neopolaris, on 04/12/2008, -0/+1The world isn't round or flat.
It's crooked -to the core... - killbert24, on 04/12/2008, -0/+0Jules Verne would be proud. I still want them to build a shuttle that can dig from San Francisco and end in Tokyo, or whatever. They could have people travel through tubes underground at lightning speeds.
- cvxdes1, on 04/12/2008, -10/+10burried as inaccurate, the earth is clearly flat.
- JSeivwright, on 04/12/2008, -1/+0Crab People!
- SCscoutguy, on 04/12/2008, -3/+2Tell Hillary Swank I said whats up!
- cowsgonemadd3, on 04/12/2008, -3/+2Burried....
The earth is not 2 billion years old.... - inactive, on 04/12/2008, -4/+1@pizzler = you submit some of the most interesting articles and lots of them. Judging from your icon, I assume you enjoy mother nature's natural stress remedy. How do you find the time to look up all these stories? Do you not have to take drug test in your employment? Anyway, thanks for your efforts, and smoke one for those of us that can't.
- susan53, on 04/12/2008, -4/+0verrrry interesting, but what does it really matter? we sit up here warm and toasty and dry for the most part not freezing our buns off or worrying why or how or "who" . ..time of billions of years..Pooh! We need to take care of this level, clean it up the best we can and get on with life. money spent on this kind of research ought to be spent taking care of starving naked and imprisoned humans and not digging up old rocks.
- amous, on 04/12/2008, -34/+3front page and no comment ?
i will niceeeeeeeeeeeeee...awesome and so weirddddddddddd
