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.
No, I wouldn't be crushed at the center of the Earth. The pressure at the center of the Earth is so high that all substances exist as a dense, solid core. Any object or being at the center of the Earth would be fully compressed into the dense core and wouldn't feel any crushing force.
If you were to dig a tunnel straight through the Earth to the other side, you would need to dig approximately 12,742 kilometers, which is the Earth's average diameter. However, practical tunneling is not feasible due to extreme heat, pressure, and geological conditions.
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.
No the heat would be to much pressure
the earth could not be in the centre of the universe unless- it was stillit was the thing with the highest mass in the solar systemand it was star!!!!!!THE WHOLE POINT OF A SOLAR SYSTEM IS PLANETS ORBITING A STAR OR STARS!!!!!
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'.
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.
It would be impossible to create a passageway to the center of the Earth due to extremely high temperatures and pressures as you go deeper. The Earth's core reaches temperatures of over 5000 degrees Celsius and pressures of millions of atmospheres, making it technologically and physically unfeasible to tunnel through.
If you were to drill a hole through the Earth, you would create a tunnel that goes from one side of the planet to the other. Gravity would pull you towards the center of the Earth, and you would experience weightlessness at the midpoint. The journey would be extremely hot and the pressure would increase as you got closer to the center. It is not physically possible to drill a hole through the Earth due to the extreme conditions and technological limitations.
probably not because all the pieces for the tunnel would float away
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.
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..
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.
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.
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.
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.
In theory, at the center of the Earth you would have no weight.
