If you could dig a tunnel to the center of the earth how long would the tunnel be?

First, it would not be a tunnel because tunnels basically go along sideways rather then down, it would be a well.
The radius of the Earth is 6,371 km and this is how deep the well would be.

Would you be crushed if you were at the center of the earth?
yes, you would probable be crushed
If a tunnel is bored through the center of earth and a pebble is dropped into it then what will happen?
Theoretically . . . (just like boring the tunnel through the globe in the first place) . . . The pebble falls faster and faster until it reaches the center of the Earth. Then it continues in the same direction but slower and slower. Its speed declines to zero just as it drifts out of the other end of the tunnel. If nobody is there to catch it, and it falls back into the tunnel, it goes through exactly the same thing in reverse ... falling faster and faster until it reaches the center of the Earth, then slower and slower until it drifts out of the tunnel again, right in front of you, at the spot where you dropped it in the first time. It's doing a gigantic pendulum, swinging surface-to-surface, fastest at the center and zero speed at each end, where it reverses. The period of the pendulum ... from the time you drop it in until it comes back up in front of you out of the hole in the ground ... is 86 minutes. Exactly the same period that it would have if it were an artificial satellite in the lowest conceivable orbit ... the same size as the Earth's radius without running into mountains or air. If there's no air resistance and it doesn't run into things, then the size, shape, mass, or weight of the pebble make no difference, in either exercise.
In the geocentric model the earth at the center of the universe which motion would occur?
The earth would revolve around the sun.
Would a human be able to survive in the center of the earth?
No the heat would be to much pressure
Where is the weight of an object maximum on earth?
I do believe that might be at the top of the largest mountain. Of course, what goes on in the changing interior of the earth probably makes much more difference. The point is: that place where the most mass is between you and the center of the earth's center of gravity (the center). Think about it. If you were at the very center of the earth (and there was a hole there rather than a very solid blob of metal) the great gravity of the mass of the earth would be approximately equal in all directions; so, you would float there. It would be on poles, because due to Earth's slighly deflated shape they are closest to Earth's center. Mind you, the gravitational force is in inverse square proportion with distance.
Does gravity switch in the center of the earth?
Gravity always attracts a mass toward the center of the Earth. If you were to dive into a tunnel through the center of the Earth and stretch your arms out like Superman as you descended, then the force of gravity would point in the direction of your fingers until you reached the center, and in the direction of your toes after that. So you might say that the direction of the force had switched around when you passed the center. But if you knew enough Physics to dive into such a tunnel in the first place, then you would know that the force is always directed toward the center of the Earth, and that "down" means different directions in different places, and you would not interpret it as a 'switcheroo'.
Why would a person be unable to dig a tunnel all the way through the middle of earth?
No One Can't Dig A Tunnel In The Middle Of The Earth Because The Tempature Inside Earth Gets Hotter As You Go Deeper. It Is Around 9000F (5000C) In The Center. It Is So Hot Inside Earth That Rocks Melt.
Can you make a tunnel from earth to the moon?
probably not because all the pieces for the tunnel would float away
If you dug a hole to China and jumped down it would you float in the middle?
Theoretically possible, but it's one of those things that doesn't quite work when you apply real-world conditions. Imagine that you somehow laid a tunnel through the center (it would have to be artificially cooled somehow since the core of the Earth is molten and it would burn up otherwise - but that's a secondary concern!). You could jump down it and (assuming you survived the G Forces of the journey) end up in the middle - but as the Earth is not a perfect sphere, the pull of gravity at the center would not be exactly the same in all directions, so you probably wouldn't float in the center, you would stick to the walls of the tunnel.
What is unbelievable in the movie Journey to the Center of the Earth?
Firstly, it would be impossible for living creatures to survive in the center of the earth. The center of the earth would be too hot to have a sea. Nothing could survive in the center of the earth. And the things of Max's should be destroyed by the hot lava. And the notes of max where still there. And how come there's a dinosaur living in there..
If you dig a hole from one side of the earth to the other side and you throw a titanium ball in the hole does it fall to the other side or will it balance in the middle gravity issue?
In reality, you couldn't dig a hole through the Earth; the core of the Earth is molten iron, and quite fluid. But if you COULD..... If you have a perfectly smooth tunnel clear through the Earth, then if you dropped a titanium (or any other material) in, it would fall, accelerating all the way, to the center. It would then rise, slowing down, until it ALMOST reached the surface on the other side. If the tunnel were in a vacuum, it would, almost exactly, reach the other end before falling back in. The one-way trip would take 82 minutes. Because of the rotation of the Earth, the ball would be banging or rolling along the wall of the tunnel as the ball fell and the Earth rotated around it.
How many tunnels could tono tunnel if a tono could tunnel tunnels?
Sheesh! It's the "how much wood would a woodchuck..." again. 1. See the answer to the woodchuck question. 2. Read on. How many tunnels could tono tunnel if a tono could tunnel tunnels. Obvious, yeah? If a tono could tunnel tunnels, then a tono would tunnel as many tunnels as a tono can tunnel. Perhaps tunefully, turbulently, turgidly, temperately, tenaciously, terribly, tempestuously, trepidaciously or terpicatively. Who knows.
Supposing the center of the earth was safe and you could cut a hole down to the center if you got down there would the force of gravity keep you there or would it squish you?
As you go down below the surface, the force of gravity would decrease, because now part of the Earth is attracting you from above, and less from below. At the center of the Earth, gravity would be zero.
How fast does time move at the center of the earth?
Time would be the least of your problems at the center of the earth. But if we could put a clock there that would be able to function at high temperatures and pressures, I don't think we would observe any time anomalies.
What is the weight of the body at the center of the earth?
In theory, at the center of the Earth you would have no weight.
If you were to tunnel into the crust of the earth what kind of rock would you most likely find there?
You would find metamorphic rock in Earth's crust.
How many kilometer would you have to dig to tunnel through the earth and come out other side show your work?
Perhaps you have imagined digging a tunnel through the earth that comes out the other side. How many kilometers would you have to dig?
