"I thought the centre of the earth was solid iron! 
Nope, too hot. Moves slightly. That's where our gravity comes from - the movement.
Well, I'll dig deep and see for myself."
Let me know if you find any morlocks. |

"is it something to do with the centrifugal force?  "
That's actually a fictitious force, though it is sometimes useful to use it in calculations and explanations.
The actual force is Centripetal - acting towards the centre.
For example, when you go round a bend at speed in a car, you think you're being thrown outwards by centrifugal force. But actually, you're just trying to obey Newton's first law of motion and continue in a straight line. It's the car that is turning into you and exerting a force on you to change your direction.  |

Yes, that is what is thought to be the case. However, it is only solid due to the immense pressure. If the pressure was reduced it would liquefy and if there was no pressure it would probably vaporise. |

You would be crushed i think. Theory has it, if a tube ran through the middle of earth, and you jumped into it, you'll accelerate to 256mph until you pass tbe core thwn start slowing down and can be catched at the other side, or grab a handle at the other side and pull yourself out |

Anyway to answer the original question - if it were possible to have a hole in the middle of the earth, my guess would be that the water would be pulled outwards in all directions like a big bubble. |

Trouble is presumably the person trying to pour water would be similarly pulled out into a big bubble too  |

"I thought it was gravity that caused movement, not the other way round?"
gravity attracts. The denser matter is, the stronger the attraction. Water would be squeezed out the way by tbe heavier metal and rise until it met a lighter Substance or a solid it could not penetrate

That's pretty much what I understood but there's a comment further up about it being something to do with movement (which I've not heard of) other than gravitational pull etc. |

Nope, too hot. Moves slightly. That's where our gravity comes from - the movement."
Gravity is produced by the interaction of masses. Movement has no effect on gravity and the core is liquid metal. However the movement of the liquid metal core produces the earth's magnetic field which induces a current in the metal which creates the magnetic field. The earth is a huge self-exciting magnet. |

"I would think it stays put as gravity would be zero??

Gravity is created by mass. Since you are in the centre of the earth then you are surrounded by equal mass then the water would be pulled equally out in all directions. Someone described it as a bubble which is as perfect a description as I could imagine. |

If it's being pulled out by and compressed at the same time.....then what? Pulled out by gravity and centipede force and compressed too by....mass? |

I think you've got to build a mighty big hole to know for sure you're right.
If you do manage it and it doesn't create a bubble, maybe it could end up as some sort of black hole type thing?..

You're thinking magnetic field. Gravity comes from mass, all mass.
It's a standard Physics A-level topic to calculate which has more gravitational effect on a baby? It's mother holding it or Jupiter. |

No, it's to take advantage of the earth's rotational velocity. Almost all are as near as possible, the few others are used mainly for polar orbits. |

All celestial bodies (oo er) have an eliptical orbit with an apogee and prerigree (closest and furthest). Thus, they have 2 centres.
I'm not sure what the fulcrum of an orbit is?? A fulcrum is the point at which a lever is placed to gain purchase, so that comment makes no sense.
To complicate things further, orbits vary, some decay, some expand and some just wobble about, so there's no single point that can be said to be the centre or centres of an orbit.
On top of that, spinning objects also precess, that is wobble like a spinning top when it slows down.
So, the whole of the universe is not proceeding like some precise clockwork orrery, it's wobbling and shimmying about constantly. |

"I would think it stays put as gravity would be zero??

_yrdwoman is a very impressive person!
To add to her comments....and my apologies for being a nerd...
The pressure and temperature at the earth's centre is estimated to be about 330 Giga Pascals and 5700 Kelvin.
So an interesting question is what state is water at that pressure and temperature? Now the states of water is an interesting subject! There are, so far as we know, 18 crystalline structures of solid water and three different amorphous structures.
We don't have empirical data for water at those pressures and temperatures but we think it would be a 'supercritical' fluid -that's is 'a substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist. It can effuse through solids like a gas, and dissolve materials like a liquid.'
Second question is what is the bath made from? If it's a steel bath, of course it would be a liquid anyway.
But, I think the answer is that the water would just effusive through the bath.
I think.

"Gravity is never zero on the Earth, as the Moon and Sun have their own gravity that affects us. Otherwise we would fly off into space."
Wonderful prospect that, amazes me how earth along with the other planets just spin round in orbit in unison how did nature work that one out otherwords how was that created.. I do know thou even thou the earth and thee others spin round the moon and sun are always on that side of the sky when visible for example if I,m sitting looking easterly the moon or the sun is always on the righthand side of me, If I,m sitting looking towards the west their both to the left of me which is the same part of the sky they always end up in the same side of the sky whatever night or day it is thou their positions are either lower or higher depending on what time of the year or month it is, so yes we are the ones who move around in that circle, where the moon and sun are stationary its fantastic when you think about it, when the moons a lot smaller in the sky it shows the earths at the other side of the circle and so on.... |

"none of them are stationery - it's all movingok but the moon is smaller some nights why is that?"
Because light diffracts to a lesser or greater degree when passing through different media densities - that's how lenses work.
So due to atmospherics and angle of the dangle, the atmosphere acts as a magnifying lens |

so do atmospherics work at different types of the year say for instance a harvest moon which is usually around august and has a golden look about it and large in size as this is a regular feature same time each year is this when the atmospherics play their part and angle of the dangle..  as you say comes into force |

Firstly, my bad, I should have said refracts, diffraction is when it spreads out after passing though an aperture.
And yes, at certain times of the year the Moon will be in the same or similar position in the sky, and seasons being what they are, then atmospherics will be similar if the climate, weather etc is similar.
Hence, the harvest moons at, well, harvest time
All this is stuff I did at O level -we did proper science in those days - ask me a hard one

The electric brae is an optical illusion and your car actually runs downhill but looks like it runs uphill. |

Also the moon's orbit is elliptical so sometimes will be closer / further away from earth than at other times |

Atmospherics refract light but does not really act as a magnigier. The big moon effect is an optical illusion that is easily proven by measuring the apparent sizes and you will find they are the same. The real reason why we perceive them as different sizes is still under discussion but you get into psychology and neurobiology and I don't understand those. People is complicated. Fizzicks is straightforward. |

Assuming the core of the earth is iron, and not a discarded plastic gnome disgraced by a previous universe, it is going to be in a rather interesting phisical state.
Preasurised and also heated by friction will render it vaporised into an iron gas, but the preasurise will slow that boiling point and compress the gas back to a super dense solid mass.
So to answer the original question of what would happen if you pulled the plug on a bath at the core of the earth I have to say it would not empty for 3 reasons,
1 it would be a ice due to the preasure,
2 the plug would be too heavy to pull out
3 you would be fucked up long before reaching the chain

They don't, light reflected from your left hand is shown on the left hand side of the mirror. It's only if you imagine yourself as in the mirror, that you would have to rotate through 180 deg to be facing yourself.
Think of it this way, someone walking towards you has a ring on their right hand, but as you look at them, it's on your left |
