If there was a hole dug perfectly through the center of the earth...?

Question

what would happen if you fell into it? Would you just hover once you got to the middle? Wouldn't gravity suspend you at a certain point?

Answer 1

What we are dealing with here is essentially a cosmic pendulum.

Next, you must force yourself to accept the following notion: if you were somehow teleported to a cave in the center of the earth, you would find that you were weightless. This is because you would have approximately equal amounts of mass on all sides of you, which would cancel each other out.

Now then. If you jumped into a frictionless (and consequently airless) interpolar tube, you'd fall, obviously, picking up momentum as you went. As you approached the center of the earth the pull of gravity would decline and eventually (at the center) cease, but inertia would keep you going.

Once past center, though, the pull of the earth's mass behind you would begin to slow you down, at exactly the opposite rate that you'd accelerated. You'd come to a complete stop just at the brink of the Antarctic end of the tube, where you'd have an opportunity to wave gaily to the bunny rabbits or whatever they have out there before beginning to fall back in the opposite direciton. This process would continue forever.

Once we start figuring for the effects of atmospheric friction, of course, the situation changes. After a certain point in the course of falling you'd reach a top speed called "terminal velocity," where air resistance would counteract the accelerating effects of gravity. With less momentum, you'd only fall a relatively short distance past the center of the earth before you stopped and started heading in the other direction. Eventually you'd reach equilibrium at the earth's center.

Answer 2

I want human beings might provide up asking this question approximately Earth, as though Earth have been a chilly, non-rotating good without ecosystem. in case you need to drill a hollow via the Earth (from the North Pole to the South Pole to steer away from Coriolis effect), the atmospheric rigidity could be so great that your merchandise might take years to realize the middle, and it would incredibly be shifting whilst it have been given there, and that's ignoring the fact that it would soften long until eventually now that. Your question could make some sense in case you replace the moon for Earth, ignoring the fact that rock rigidity might close the hollow until eventually now it must be finished. Then, in a vacuum, the object might oscillate between the ends of the hollow. Hooke's regulation grow to be derived for springs, in spite of the incontrovertible fact that it relatively is utilized to your gravity concern by way of fact the rigidity of gravity could be without delay proportional to the area from the middle. See links for derivation.

Answer 3

Assuming that you could withstand bone-crushing pressures, and the scolding tempuratures of molten lava surrounding you, yes. But the hole would need to continue out to the other side. heres why:

As one falls through to the center of the earth, they build up speed and fall faster and faster. As they aproach the center of the earth, they would easily be going over 100 miles an hour. Now, the center of the earth may be strong, but it won't bring a person travelling 100 miles an hour to a complete stop. So there fore, you would have to bouce down the other end of the hole, and then back towards the center, and back and forth and so on until you have slowed down enough for the center to stop you and just let you hover.

Answer 4

i imagine that you would probably incinerate into ash shartly after falling into the hole. the earth's mass is set up into three different categories: crust, mantle, and core. the crust is the layer of dirt, sediment, rock, and other sub-terranean materials that we live on. it is approximately 10 kilometers deep. Then you have the mantle. this layer is quite a bit larger than either of the other two. the mantle is extremely hot and consists of thick amounts of lava and magma. when volcanoes erupt, the stuff that shoots out comes from the mantle. the mantle is approximately 5000 kilometers deep. Then lastly is the core. it consists of what is speculated to be gasses that are 10 times hotter than the sun. so in closing if you were to fall into a hole dug to the center of the earth you would disintegrate after a few miles. by the way it is flat-out impossible to dig beyond the border of the crust. scientists predict that the inner edge of the crust is as hot as the sun.

Answer 5

if there is a material with the melting point greater then the 7000 degree celcius u can able to dig the earth if not there is no way to dig the earth till the center of the earth
After find the material u can dig a go to the center oof the earth
If not u will die and burn into ashes

Answer 6

The earth would spit you out (in pieces) like hot lava from the hole you jumped into. Consider the temperatures and extreme pressure. If those throw the tons of magma sky high then a small mass of human should almost make it out into space.

Answer 7

By the time you reached the center, gravity would be irrelevant. You would be burnt to a crisp by the earth's inner core long before arriving there. That ignored, I guess you'd bob around like a ping-pong ball suspended by a hair dryer's air stream once you reached the center. :)

Answer 8

You would either burn too close to the core or the gravity crushes you. You might burn because the Earth's core is hotter than the suns Photosphere (the outside layer of the sun)

Answer 9

Scientists have tried and got a huge amount of miles down but the earth was to hard towards the core and too hot. You would fall and burn.

Answer 10

assuming you do not burn up, you will fly to the other side of the earth, or rather a bit below it b/c of air resistance. So you would not be able to get out of the hole and fly back, ending up even further from the surface. you will keep oscillating like that untill you stop at the center of the earth.
