Gravity - Explain this to me...
 

anywhere I stand on earth I am forced down. that being said what If there was a huge hole right through the earth and I jumped into it?

Would I stop in the middle of the earth and float there?

yea, that's actually what hell is, devil has a secret tunnel like that, throws people in there and they float in the middle of earth forever... :thumbsup

You would pop out the other side at zero speed right as you left the hole. I.e. as your feet cleared the hole on other side you would be at no speed and be ready to fall again.

This of course ignores all the other issues of heat, and crap.

GFY IS NOT GOOGLE!

if I searched jumping into a hole on google.... j/k

but you can go fuck yourself.. since thats what gfy is for.

Um you asked the google the wrong question. Yours is would you be pulled in all directions.
Seems he asked if there was a hole from one side and out the other and you jumped in.

PS. If everyone ran to google about everything, the board would have to topics really.

Not gonna take the bicker-bait.

That wasn't the point.

Guess to make it make sense it should be explained how I remember it.
You would keep falling at terminal velocity until the moment you passed the center. From that point you would now be decelerating as you passed the center and would come to a full stop at the moment you left the other side of the hole.

What you have described could not happen.

It would be impossible to drill a hole through the earth, as the centre of the earth is molten lava -- and is very hot. So, if you were able to drill a hole through the earth and break through the mantle your hole would fill up with molten lava preventing you from jumping into it.

And btw no i didn't. I don't even think you read all of it.

damn its hard to resist bickering.

When I read the first time even though it is in my quote (not in next quote as it was added via edit) there was no yahoo link listed. I read the google one only and then hit quote - reply.

Fuck it all. I dont want to argue. I should have just said this is not google and not posted the link at all... I guess. Since my point was he should have searched himself.

and now im already waiting WAY to mech energy on this.

Curious how gravity works.. why does everything get thrown into the center of earth.

when things are spinning you get thrown to the outside, not towards the center.

surely I could google this so I don't feel so stupid, but what the heck.

I read them all, makes sense.

You would wind up in China

Without going scientific - mass attracts mass. The more mass something has the more pull it has. The pull is stronger than the outward spiraling force you are talking about.

This is my excuse when I sleep with large women. :2 cents:

I think that may be mass minus alcohol minus hornyness = attraction.

I LOL'd :1orglaugh :thumbsup

Yea sorry for being a dick in the first place with the google comment. Somtimes I come to GFY just to be mean I think. :/

I was always told the center of the earth was super hot. So I guess you'd burn up before you got there.

Also... the further away from earth you get you get lighter. So then the closer you get to the center it increases? Is that right? I dunno, I've never been there, but I just assume that's the case. If that IS the case, wouldn't you burn up from air friction, or would you just hit terminal velocity and continue past the center for a little ways?

To assume that once you past center that you'd continue is ridiculous. The argument could be made that if you dig a regular hole deep enough that you'll be repelled by gravity.

I think that if you could pass thru the center, that would mean the center was cold enough for this to happen. If that's the case... we're all dead.

There is no way to pass thru. There is only GFY.

you would also get heavier as you fell, and time would slow down, until you burned up.... gravity would not matter

its all good, I don't take anything here serious.. its expected.. many times I resist posting shit here because I know Ill make a fool of myself, but before posting on here I discussed it with friends I had over for dinner and got a few answers and wanted to hear what everyone else would think. I posted on gfy so I didn't feel left out as not knowing any of this.. surely google has the answer for everything but thats not entertaining :)

ok, a better way to ask the question so that his original intent was addressed, would be to use a different object other than earth, say a cold moon somewhere far from the sun, so that it was basically solid throughout and not molten in the middle, and drill a hole through it.... (and no atmosphere so that the air resistance was out of the issue as well)



and to the other thought, gravity has nothing to do with spinning (although you can fake gravity by spinning something)

that question just made my brain ooze a bit of fluid from my left ear.

ok so earth has something to do with gravity.. or space?

if suddenly earth was gone from this spot in space.. and i was super human and survived all of whatever could happen with the missing earth.. lol.. would there still be gravity in this "space" and would I now float in that special spot.

or does it have something to do with the earth spinning.

You would not get heavier (any significance) as you fell. Read up on Newtons shells. Nor would time slow down. Theoretical question also ignored the heat issue.

no, all objects have gravity, the more mass they have, the more gravity, it has nothing to do with spin


also, mass always stays constant, no matter the force of gravity on you..... eg. your mass is the same on Earth as it is on Mars or in 'weightless' space (I should correct this, because mass actually increases as you accelerate to the speed of light to the point of infinite mass at the speed of light, which is the reason that matter can not go the speed of light and for sure never faster than the speed of light)

If everything else was gone (guessing sun and other planets still there). Then you would have your own gravity. The space that earth had occupied would not though.

If there wasnt such a thing like a super hot core, you would def. float in the middle (if you could survive in a vacuum) - but i doubt this "tunnel" would last long as i think the object (moon/planet) would collapse pretty quickly.

Duh .. didn't anyone ever see that fucking bugs bunny episode ???.. Jeebsus .. everyone knows you end up in China ..

every answer brings me with 10 more questions.

you say more mass more gravity.. so now makes me think.. ok explain black hole.

You would be weightless in the middle. You still would need a way to stop first to experience it. The falling would not just stop all by itself. It also would not be a vacuum, you just would be experiencing equal gravitational pull from all directions. Not sure why you think the object would collapse.

hypothetically speaking and if there was a vacuum, you wouldn't float in the middle, you would fall back and forth between different sides of the object for eternity

Lots of fucking mass.

Remember more mass does not have to equal bigger size. Simple form 1 ounce of lead has more mass than aluminum.

not sure 100% on this, but it is an object of great mass that is so dense that it has extreme gravity that sucks in everything close to it, even light photons

if you dig straight down and through the exact center of the earth from anywhere in the 48 contiguous United States, you'd come out in the Indian Ocean. Only in parts of Argentina or Chile would a straight hole emerge in China. :)

your mom is so fat... she comes with her own black holes.

:1orglaugh

Realized I screwed this up as I was writing it, it is what I get for doing this and my recipe blog at same time. Meant to so a teaspoon not an ounce. Was not trying to use a weight measurement.

Truth is that nobody has any idea what is in the center of the earth and therefore any theories on this subject are just that, theories.

Just to clarify, the mass of an object bends space-time and the amount of the bending communicates how much acceleration/gravity other objects experience when near that object. At least that's the general relativity explanation. On very tiny scales a new theory is needed.

Trust me, I have a PHD from the Greater Correspondence College of Tampa with a minor in VCR repair.

Speaking of black holes, when I was a kid, a friend and I rented a porno called "Hot Black Holes" on his mom's video card. When she saw the receipt she asked what it was and I got all all nervous and then my friend replied it was an educational movie about space. :1orglaugh

Gravity is an illusion and this existence is all a part of a simulation you willingly signed up and paid for.

If we give you all of the answers to how things work, that would destroy the entire purpose of it all, now wouldn't it?

Back to your regularly scheduled program...

I was just pondering a thought, I wonder where the center of gravity is for a torus shaped object?


it is kind of like a donut, a round shape with a hole in the middle, could one possibly exist in the universe of any substantial size or would gravity not be able to hold it together in that shape?

Electric Universe FTW

The center would be technically a vacuum and nature/physics hates vacuums. There is a big reason why matter likes to form spheres. So I would tend to think no it count not exist for any real amount of time.

I do think perhaps a tube vacuum could appear, potentially bend due to external forces and touch its other end. Still think it would collapse once it did into a sphere vacuum though.

Looks like a star in the middle or something else very dense and bright. Guessing maybe a cone shape more than a donut.

I really don't know much at all about them, but I was reading about how they are theorizing that some extremely massive black holes have a torus orbiting around them

pretty wild stuff to try to imagine
