If you...

dug a whole through the center of the earth and jumped in... what would happen to you?

Assuming, of course, that it is possible to dig the hole and the heat, gamma radiation, and toxic gases wouldn't kill the person, here is what would happen:

1. The person would initially fall and accelerate at the rate of acceleration due to gravity (G), 9.8 m/sec/sec (exact G depends on latitude, density of surrounding rocks, and altitude).

2. Terminal velocity of between 200-350 km/h would be reached in about 10 seconds or 500 meters. The terminal velocity is a function of G, mass of the falling object, and its coefficient of drag. Remember that air resistance is proportional to the velocity of the falling body squared. In other words, the faster you go, the more the air resistance. For an object to experience terminal velocity, air resistance must equal weight. The biggest variable in this case would be the amount of drag due to posture - if the person was falling head first (or feet first) to minimize aerodynamic resistance, or a belly flop position with arms and legs extended for maximum drag. Loose fitting thick clothes would also slow him/her down, as opposed to being naked (ouch!) or wearing some type of speed skaters clothing.

3. Once the person has fallen a few km, G would decrease because part of the mass of the earth would then be above the person. That means that the weight of the person is decreased but the mass stays the same. Also the atmospheric pressure would increase, resulting in more drag. In other words, weight and G are decreasing but drag is increasing. Therefore terminal velocity would be decreased. However momentum would ensure that the actual speed was slightly more than terminal velocity, so the net effect would be that velocity would lag behind the increased drag and decreased G, so that the person is travelling faster than terminal velocity when drag starts to be greater than weight.

4. G would steadily decrease as the center of the earth was approached, until G is exactly zero at the center.

5. At the center of the earth, the person's actual velocity will still be faster than the calculated terminal velocity due to momentum. G is now zero, so the person's weight is zero (but mass doesn't change). Air pressure is now at its maximum.

6. The person would continue traveling past the center of the earth due to momentum, until the air resistance and gravitational force from the opposite side stopped him/her. Gravity would then pull him/her back toward the center in a "yo-yo" effect.

7. The person would oscillate back and forth a few thousand times, in ever decreasing movements due to the friction of air resistance. Every time the person passes through the center of the earth, s/he would be traveling a bit slower.

8. Air resistance would dampen the up and down (relative to the departure point) oscillations until a steady state of no movement was reached exactly at the center of the earth in a state of weightlessness and gravitational equilibrium. There is no gravity at the center of the earth because there are equal amounts of mass surrounding you.

The greatest autobiography I've ever read :D

"My name is Charles Prescott Barris. I have written pop songs (including 'Palisades Park'). I have been a television producer. I am responsible for polluting the airwaves with mind-numbing, puerile entertainment. In addition, I have murdered 33 human beings. And I am damned to hell."

.

this is a film about a man and a fish. this is a film about dramatic relationship between man and fish... the man stands between life and death. the man thinks, the horse thinks, the sheep thinks, the cow thinks, the dog thinks, the fish doesn't think... the fish is mute, expressionless. the fish doesn't think because the fish knows everything... the fish knows everything.

Good times, Noodle Salad

"Am I not?" Jack Sparrow (Johnny Depp)

"Hey, we all have these sad stories to get over..." Carol (Helen Hunt)
"That's not true. Some have great stories, pretty stories, that take places at lakes with boats and friends and... noodle salad. Just noone in this car... but a lot of people, that's their story: Good times, noodle salad. What makes it so hard is not that you had it bad, it's just that you're pissed because so many others had it good." Melvin (Jack Nicholson)

"Karloff? Sidekick? FUCK YOU! Karloff does not deserve to smell my shit! That limey cocksucker can rot in Hell for all I care!" Bela Lugosi (Martin Landau)
"What happened?" Ed Wood (Johnny Depp)
"How dare that asshole bring up Karloff? You think it takes talent to do Frankenstein? It's all makeup and grunting. [Mocks Frankenstein]" Bela
"Bela, I agree with you 100%. Now, "Dracula," that's a role that requires talent." Ed
"Of course. Dracula requires presence. It's all in the eyes, and the voice, and the hands..." Bela
"That's right. That's right. You seem a little agitated. You wanna to go outside and get some air?" Ed
"BULLSHIT! I'm ready now! Roll the camera!" Bela

"I came up with a new game-show idea recently. It's called The Old Game. You got three old guys with loaded guns onstage. They look back at their lives, see who they were, what they accomplished, how close they came to realizing their dreams. The winner is the one who doesn't blow his brains out. He gets a refrigerator." Chuck Barris (Sam Rockwell)
