Little Giant Ladder

Let's say there is a giant hole all the way through Earth1st)If you jumped in would you fall back and forth until you eventually came to the center2)or if there was a ladder and you climbed down, would you just float in the center or would you be crushed by gravity into a little ball of mass?Now, I assume strange stuff to begin that you probably can't have any of this with no center of gravity? But if it's possible to put that asideOr, there for what would happen to earth if they did drill a hole from one side through the other and there was no center of gravity, would the planet just fall into space?and if so would it be right at the moment you dug at the center?Really, I just want to know the 2nd) scenerio if you would float or be crushed and there is some super mega metal wall so no burning up from heat or anythingjust gravity curiousity

Answer #1
At the center of the earth, you would not feel anygravity. This isbecause the gravitational pullfrom every region of the earth isexactlycounteracted by the gravitational pull fromthe corresponding region on theopposite side ofyou. This all adds up to a great bug zero.Ofcourse, you would perish in molten lava longbefore you reached thecenter of the earth, butthat's a different matter.

Answer #2
Since the mass of the earth would be more or lessevenly distributed in all directions around you,you would indeed float as if you were in orbit.Too bad all the molten Iron and Nickel would burnyou to a crisp long before you could reach thecenter.

Answer #3
There is no gravity at the center of the earth.You are pulled equally in a ll directions.

Youd go back and forth, but you wont know bout itcuz youd be incenerated mwahahaha

Answer #6
You would be pulled to the side of the hole as youwere falling. It is unlikely you could fall intothe centre, because you would be closer to oneside, which would attract you. You would thereforefall into the hole, but as you approached thehollow core, the gravity from the mass of theEarth, that is the edge of the centre cavity,would attract you.If you were somehow placed intothe centre cavity, then you would probably justexperience weightlessness, the pull of the Earthis not enough to pull us apart now, so it shouldnot be strong enough then, either. If you movedcloser to one edge of the cavity, then the gravityfrom that closer portion of the edge would drawyou to it, and you would fall toward it.

Ok first of the earth's magma outer core spinningaround the earth's solid inner core causes theearth's em field or (electro- magnetic field) thatkeeps out all the suns radiation. If you drilleda hole to the middle of the earth you woulddisrupt the magma flow and hence destroy the emfield. will this field down we would be hit fullforce by the suns radiation and be fryed. If youget by that there is a possibility that because ofthe huge amount of gravity being pushed on to anow unstable core that the earth could implode. Again if you get by that you have to worry aboutthe pressure of millions of tons of rock beforeyou even get to the core so in all likeliness isay you would probably die before you even getthere. But again if you managed to reach theinner core the heat would be about 1/2 the temp ofthe sun and would melt even your bones. But sinceyou drilled a hole through the core you created avacuum much like space which in the middle wouldhave zero gravity.

[Short answers]1) No, but if you sealed the endsof the hole and vaccuumed out the air, you couldbounce back and forth indefinitely2)No, gravity ismax right here on the surface, and decreases asyou go down. But you would not be strong enoughto overcome the bouyant forces of denser air toclimb down much further than about 50 miles.3) No,constructing such a hole, tho a monumental (andvaluable) feat, would not cause any harm to theplanet.[Long explanation, my response to aprevious posting of this question] If you were ina hollow sphere in the exact center of Earth, themass of Earth would be evenly distributed aroundyou, therefore also the gravitational forcesgenerated. If the sphere were small compared toyour body size, you'd experience microgravity(weightlessness), similiar to aboard anunaccelerating spaceship. If the sphere were muchlarger than your body size, you'd feel a slighttugging toward the nearest wall of it, i.e, you'dexhibit a weight of grams or ounces, depending onthe size of the sphere, being completelyweightless only when you were in the exact centerof the sphere.(Added after your additionaldetails) -Yes, if you jumped into such a well youwould have to climb or be lifted out:There's airin the well. Terminal velocity for a human inEarth freefall is in the range of about 100 (ifyour fall flat, arms and legs extended) to 200miles per hour (if you "dive", body and limbsstraight). If it weren't for the fact that thedensity of the air wouldn't be constant withdepth, you'd maintain close to this speed for thefirst few hours (remember, it's 4000 miles to thecenter from here), until you were deep enough thata significant percentage of the mass of Earth wasbehind you. Then you'd gradually begin slowingdown due to air friction versus the decreasing netgravitational force on you. After a couple of daysof this, you'd be approaching the center of Earthat about the same speed as a feather fallingthrough the air.But if you factor into your wellthe fact that air pressure will increase by afactor of about 10 for every 10 miles down you go,you'll figure that you're going to have realtrouble even get close to the center. Thereasoning is this: at sea level, the volume of airequal to the volume of a person (about 3 cubicfeet maybe) weighs about 0.006 pounds. Every 10miles down you go, that same volume will weigh 10times more. If I have it figured right (anyone outthere???), somewhere between about 40 and 50 milesdown the air density will equal that of water. Youwill float at that point just as if you were inwater. Swimming down much further will beincreasingly difficult since unlike water, thedensity of the air will still keep increasing withdepth, making your bouyancy progressively moredifficult to overcome. The only way to be able tofall all the way to the center would be to sealand apply vacuum to your well. Then when youjumped in with your spacesuit on, no air or airfriction will slow you down. If the vacuum wasclose to perfect, you'd accelerate at a 1G rate tothousands of miles per hour within minutes (100seconds at 1G = 32ft/sec^2 =3200ft/sec~=0.6mps=2182mph), Gradually, this rate ofacceleration will decrease as more of the mass ofEarth becomes behind you, becoming 0 as you passthrough the center, then gradually tending toreverse your acceleration to the point where yourspeed would be zero just about time you hitsurface level on the opposite side (you did digALL the way through, right?). Then you would startfalling back again, and if your vacuum wereperfect, continue this cycle indefinitely.

Answer #9
Inside a spherical cavity at the center of theEarth, you would feel no gravitational forceanywhere inside the cavity. That is, you wouldn'tbe pulled toward the wall if you drifted a littlefrom the center. This is true of thegravitational force inside any homeid (that is, ashell whose inner and outer boundaries are similarellipsoids, similarly oriented).There would,however, be a gravitational effect: time wouldprogress slightly more slowly than it does outsidethe Earth. This is a general relativistic effect.

Answer #11
Gravity is strangely weak.Lets, our musclesovercome the gravity of the entire Earth.A simplemagnet can do this also.Gravity is 10^39 timesweaker than the electro-magnetic force.Anyway, ifyou positioned yourself in the Earth, such thatthe gravity from the surrounding rock (Earth) wasthe same in all directions, yes, you would "float"there. No crushing would occur.How could it, youdon't get crushed when standing on top of theEarth.Gravity is just far too weak.A possibleexplanation for the weakness of gravity is givenin M-theory.See here for a really good documentryon string theory which coversthis:

Answer #12
You would fall at a decelerating rate past thecenter and oscillate back and forth until youstopped at the center. If you climbed down aladder you would become lighter as you approachedthe center. When you climbed back out you wouldcontinue to get heavier as you left the center andneared the surface.
