God only knows how a subject on the Parry and Hicks debacle got so off topic on the LFC footie board, but here's a damned good question that was posted on the thread to ponder over:
If you bored a hole completely through the Earth from here to the antipodean side, and then dropped a lead ball down it; where would the ball stop falling?
I reckon it would float at the core of the earth. Well it wouldn't actually, cus it would melt and dissapear.
-
That's some thread-drift. Once it gets past the centre, does it cease to fall, then begins to ascend?
-
tunble: Must be Sunday ::)
-
I shall reply shortly with an answer.
-
Making assumptions that:-
The ball wouldn't melt and
Negligble air fritction
Then the ball would pass through the core and out the other side about 530 feet before gravity stopped it and started pulling it back towards the core.
-
Are we assumming that the lead would not melt? If so then surely gravitational pull equally applied from all directions should make the ball "hover" at the halfway point .............. but that assumes that the hole bored had actually gone through the middle.
Personally I doubt that B&Q sell a drill bit long enough to find out.
-
It would EVENTUALLY hover, after a bit of ping-ponging about the core.

If the hole was bored in two directions thus creating a 4 way junction at the center, it would surely spin and hover in the middle, thus perpetual motion would be created? rubschin:

How? Gravity from the 'other side' would surely force it back down to the center?
Ey MR, what's all this 530ft nonsense about then?
I'd have thought more like 297 tbh.

Show your workings! Mine assume gravity at 9.8 m/s/s and a terminal velocity due to gravity of 125mph.
-
I understand that John Moores University, Liverpool have called all their greatest academics to a meeting to resolve this issue once and for all.
The meeting will be held in the faculty telephone kiosk at 12 noon tomorrow. Dress Optional
-
Show your workings! Mine assume gravity at 9.8 m/s/s and a terminal velocity due to gravity of 125mph.
And your allowance for higher air density and friction?
Not to mention eddy current forces as lead (a conductor) passes through the centre where the magnetic field will effectively reverse (from the lead ball's perspective).
-
Liverpool + "greatest academics" are words that can surely never go together?

We are talking Newton's Law of Gravity here. Don't go bring magnetic forces into it 'cos they would cause the lead ball to spin when it reached the centre point and then anything could happen.

As I assumed the ball wouldn't melt, it was obvious that my ball (!) Was not made of lead - more like something akin to the tiles on the Space Shuttle, thus no magnetic interference.
OK!

If you place a celluprime into the equation which in my way of thinking is of utmost importance, x in fact =18/655 therefore leading to an optimum terminal speed minus the force of gravity divided by 4.222. and concludes to the eventual height of desent or asent, depending on which way you look at it, to being the exact height of re-entry downwards into the chasm before falling back towards the core, where it will assume constant equalirsiasm in a circular motion pointing n,w,s, and east at the same time.

And I know I mixed my metric and imperial measures, however, I am sure this august body are capable of the requisite conversions.
A far harder question is "how many beans make five"?

The answer to that is "A Train"
Now I have one for you
If it takes a week to walk a fortnight ~ how many apples in a pound of grapes?
-
"A train" is incorrect.
The proper answer is "a bean, two beans, a bean and a half and half a bean".
Silly hound.

So where did the train come in?

Meanwhile, whilst out 'up me 'ill' this avvy, I've been doing some very serious thinking..... rubschin:
There are many more unanswered scientific questions that need resolving.
Stand by you egg 'eds............. tunble:
Anyway, it's just under an 8000 mile hole we've got to dig, so we better get crackin'.
If I start in our garden, we should break through into the Pacific Ocean just north of New Zealand in errrrr...approx 3500 years time I reckon, or 35,000 including ale breaks.

Always too much apparently. ::)
This is a serious question. Why is it you can drop a cat from that height, and it may well survive, but an equal weight dog wouldn't.
Why is it that you can drop a leaf and it will float to the earth, but an exactly the same weight stone sculptured to the same shape would plumit?

a) Cats are clever enough to land on their feet
b) Wind resistance

It's a matter of aerodynamics. The greater the ability of the object to obtain "lift" the more likely the object is to "float" to earth. For example a cat tends to spread itself (think those "flying squirrels") ~ a leaf is aerodynamically more suited to be able to obtain "lift" than a stone .... even if they weigh the same (which is unlikely)

Thats an evolutionary factor, cats are more agile and have a more highly developed sense of balance which means that they are more likely to land feet first allowing them to absorb the impact.
Anyway back to the original question the answer is that you couldnt drop the ball in the first place as the pressure of the magma would stop any object from being able to be dropped even if you are able to continue drilling the hole in the first place. noooo:
