"Hawkling prefers another possibility: that there are other forms of intelligent life out there, but that we have been overlooked. If we should pick up signals from alien civilizations, Hawking warns,"we should have be wary of answering back, until we have evolved" a bit further. Meeting a more advanced civilization, at our present stage,' Hawking says "might be a bit like the original inhabitants of America meeting Columbus. I don't think they were better off for it." - Coming from Stephen Hawking

As the well reknown theorist say this and people will and must  believed him.
ALIEN DO EXCIST. 
Reject The Hollow earth theory and believed in Aliens, or until he acknowledge it.

Why do aliens have to be organic and then have head, hands, legs and others? Cant alien be something we never imagined b4?

Angry? Dont assume to much and judge by the word and say "oh ! your angry" I may feel happy, sad or boring. Statement is discuss at first post.. are you dicussing or just you like to troll around? How can theory fall apart if there is just only theory to contadict it? No one knows the earth is solid and no one know the earth is hollow. Everthing is just by theory, hence the Hollow Earth Theory. 

If you dont understand than feel free to modify it. 

Why do they need restriction at the polar ice?

Gravitation Inside A Uniform Hollow Sphere
The gravitational force inside a hollow sphere shell of uniform areal mass density is everywhere equal to zero, and may be proved by the following argument:

Let the sphere have a radius a. Place a point P inside the sphere at a distance r from the center where r < a; i.e., r is strictly less than a. Draw a line through P to intersect the sphere at two opposite points. Call these points  and. Let the distance from P to  be r1, and the distance from P to be r2.

Now place a differential area dA at , and project straight lines through P to acquire its image dA at . These two areas subtend a solid angle d at P. Let the sphere have areal mass density (kg/m2). Then the net differential attraction dF of dA and dA at P directed toward  is just

dF = ( dA /r12 - dA/r22).

But dA = r12 d, and dA = r22 d by definition of the solid angle. Thus,

dF = ((r12 d)/r12 - (r22 d)/r22) = 0.

This result is true for all choices of dA and dA. The gravitational force within the sphere is everywhere equal to zero.

==
holy crow.
first, newton's universal law of gravitation:
F=GMm/rr

let me state the flaw in your maths above.
first you messed up everything.
label and statement are all messed up, and could not be understand.
I tried to do your math above but I just could extract the information.

2. how do you know the mass of the inner sun and the outer right of sphere/crust?
how do you know the density of them ==

3. the gravitational force exerted on between 2 mass still obey the inverse square law.
there is only one locus neutral point (zero gravity), not everywhere.
when getting close to one side of mass, the resultant gravity will be dominant on that side.

4. to do the calculation you need the correct dimension and the mass of the whole structure,
which you don't have here, and definitely would not be able to find out.

5. such a complicated system (the hollow sphere with a core suspending at its centre),
the math would have been far more complicated.

last of all,
I might not be the champion of national math olympiad,
yet I did win some title in some national and overseas math competitions.
=)
whose word is more convincing now?
and don't tell me the next reply you are going to type is,
'I can claim that I'm Math olympiad too! no one can disprove it!'

okay okay enough =)

I may have misunderstood you. Likewise you misunderstood me too. For that matter, I dont think anyone understood the TS either. I beileve the TS started this thered because he was doubtful of certain things about hollow earth theory at the same time there are things he considered having merit. He wanted to hear what we could or could not accept and why so that he can formulate his own standpoint. As it is this theread started of with sarcasm accompanied by a simple statement of disbelief (typical of PhD School - heading toward Kopitiam soon). The funny part is frictional movies were quoted as if these movies had more merit than the hollow earth theory. The more crude remarks the forum throw at TS, the more cut and paste he produced. 

As an arts student, I admit my science is not that good. What I can see is the stuff TS produce have their points when they challenge what is "acceptable science" (by acceptable science I means ideas that nobody in these forum dispute. Seriously, even Hawkins dont makes sense to me). Both sides have different views of gravity. I wonder how many of you realise the inconsistencies you have brought out just to disagree with this theory.

Lets me ask what I put in bold. Since everything has gravity, why are there no dust ball floating around now. How often do you clean your room? I am sure there is still dust every day. Why only during formation of suns and plantes they can clump together but not now? Since you say the center has the strongest gravity why are humans not suck in to it to form the clump? There should be one center and it should be all powerful to suck all to it thus forming one big clump not little clumps here and ther and finally orbiting around it.

Robert,
Dont you think one day we will end up like kopitiam if we continue to hurl insults just because someone come up with a fairy tale that strongly offends your belief?

Pasting and copy latest info for what we dont know why the north pole is kept out of peoples view. Some explorer may have come across it, there are also people who investigate this "hole" but their progress has been hinder by goverment. Google earth have a blank spot on the top or photoshop as well as any sat images. At the North Pole, the sun is permanently above the horizon during the summer months, so why there is no full sat images during this time?
All information we gather are never 100%. Nothing is 100%.
If you are in to science without a shred of belief i tell you this, If i ask you to jump, spit and shout "Oi, come out yer dead people" at the cemetary at 12 midnight, will you do it? Surely you would be afraid of getting "someone" angry. From that point your science dont apply.
Hawking believed lifeform from different planets by calculation and announce it to the world, but the Hollow Earth theory is where alien dwells according to people who said to have been there. Hawking already open a new chapter of theory when he announce alien is "real" through calculation.
So which part does this Theads fit with kopitiam? If you think this theads should be at kopitiam then any theads relating to Stephan Hawking theory should go there as well. 
We dont know on that robotic speaking chair of his, he also calculating the Hollow earth theory, thus another theory of alien pops up.

Russian and the US has been neck and neck going for the Moon. But in the end, we dont know who win. Russian said they win, US said they win but there is a conspiracy that US never made to the Moon. They make stage and film it from there.
As you read it, Russian want to make a publicity stunt.. so it could be somewhere but not anywhere near the "hole".

Coordinate for hole has been said at 87.7N lat, 142.2E long (2.3 Degree from pole). But mind you there are occurance at the north pole. From sea level, mirage can be seen and also it has been said that the magnetic pole can tamper with the compass and electronic stuff.

Now, People Anywhere around the world and you know that Earth is Alive.
Under the Law of Nature. How many living thing can you find which is solid from the inside ?

In the 1950's Prof Hapgood came up with the Pole Shift idea. He believed that since the polar ice caps were continually increasing in size (and weight) that this might cause the Earth to tilt on its side. Since the polar ice caps are unevenly distributed in both the Arctic and Antarctic (e.g. Greenland which lies on one side of the Arctic), he believed that a point would be reached where the centrifugal force of this uneven distribution would cause the Earth to tilt over. Albert Einstein was very impressed with this idea just prior to his death.

I have wondered if the recurrence of ice-ages might be better explained by way of Pole Shift theory. The North Pole was once located in Wisconsin, USA. Similarly, the South Pole was once located in what is now the Sahara desert. The poles have shifted a great many times. But was this because continents were slipping and sliding hither and thither across the face of the Earth or is it that the entire Earth shifted?

It is fashionable these days to blame the extinction of the dinosaurs on comet strikes. The extinction of the dinosaurs was not a one-time event. Indeed, multitudes of species became extinct a great many times. There have been many biological extinctions in the history of our small planet. In the 1980's some scientists conducted a study of these extinctions and discovered to their amazement that there seemed to be a regular pattern to them. Their results were published in Science. These extinctions seemed to occur approximately every 26 million years. What could cause this? The problem with comet strikes is that they are destructive in the sense that the comet/meteor which does the deed is itself annihilated in the process. It is almost absurd to expect comets to strike the Earth with a fixed periodicity. Could it therefore be that something else is at work - something here on Earth for example?

One scientist, D. E. Loper, noticed a correlation between biological extinctions, magnetic reversals, climate change and other geological phenomenon. A number of scientists have noticed a correlation between magnetic reversals and biological extinctions and have written papers about this. Could it be that biological extinctions are also caused by the Earth itself undergoing upheavals of an internal origin?

I do not doubt that comets and meteors must indeed have fallen on the Earth in the past. There is considerable and irrefutable evidence of cometary strikes. And very possibly some of these strikes wiped out large numbers of animal species. However, it is a different thing to say that all biological extinctions are caused by comets. And it is here where these studies of periodicity come into their own. It might even be that the Earth itself is unstable and that it is the main cause of most biological extinctions over and above those caused by comets.

It would seem as if magnetic reversals coincide with other things including an increase in volcanic activity. Could it therefore be that Pole Shifts are the driving factor here? Magnetic reversals might be nothing more than a record of past Pole Shifts. And if the Earth moved physically (because of some weight redistribution), it is entirely possible that this triggered volcanic activity and earthquakes on a vast scale which then destroyed large numbers of animals.

There may also be evidence of rapidly rising land which perhaps builds new continents. Velikovsky pointed to the large number of Zeuglodons (an extinct prehistoric whale) found in Alabama and the Gulf States. Could it be that what was once sea-bed suddenly rose to become dry land? Could this be caused by a Pole Shift?

I have given the Pole Shift idea a special place in Hollow Planet theory. Let's suppose, as per the deep quake evidence inside of the Earth is not as hot as scientists presume it to be. This being the case one would expect water to flow deep inside the Earth. Such water may create tunnels and cavities. There may even be vast oceans of water inside the Earth. Thus, unbeknown to us on the surface there may be an ongoing redistribution of mass going on inside the planet all the time. Perhaps one day some of these cavities become weakened by tremors or by their increasing size and perhaps some of them collapse. This might then cause an entire continent above to then sink into the sea. And perhaps the compressed underground ocean forces other land to rise elsewhere. Gravity may also play a role in this. If gravity is affected by electric currents inside the Earth then this may also help to trigger a rise and fall in land on the surface of the Earth.

In recent years some scientists have been thinking seriously about the Pole Shift concept and some papers have been written about it. Their term for it is "Polar wandering".

One also finds various evidence in the polar regions suggesting that the climate there was much hotter. Was that because the Earth as a whole was hotter or because the polar regions actually lay near the equator?

Dodwell, an Australian astronomer, studied gnomons from around the world. He determined that they had indeed been reorientated within the last few thousand years and that a Pole Shift had occurred within human history.

Finally, I point to the inclinations of all the planets. All the planets are aligned differently. Even though all the planets formed at the same time and rotated in the same direction we find that they are all inclined differently. Venus for example is actually upside down (i.e. retrograde rotation), while Uranus is lying on its side. In fact, I have seen suggestions by some scientists that Pole Shifts may have occurred on the Moon and Mars. Could it be that Pole Shifts are actually endemic to all Hollow Planets and that they are constantly reorientating themselves due to internal mass redistributions which we know nothing of?

Actually, before the movies there are also stories for the old days regarding the "City of Heavens", Chinese in Tibet know it as "Shangri-La" or "Shamballa" and most of nearly all the folk stories are usually the same in different country. Now, how did the story of this underground city is known to all past people? All of them heve different version of city but the same location.. Underground !
But if i were to go there, and could find the hole to inner world. Would i come back and tell you all? The stories states many intresting thing about the inner world.

1.) people goes in there can live longer "Forever".
2.) Technologies are Advance.
3.) No war, Violance and etc.
4.) Will never go hungry.
5.) More relaxed
6.) Everything is free.
7.) Can visit other planets. ( Tour guide to other planets)
8.) Human potential capability "Telepathic" or other is higher.

If everyone know the hole and the stories is true. Ill bet you 100% from India to Africa and other poor nation of poverty and war will go there to seek refuge. So the USA will lose power over almost everything. No people will want to live on the surface anymore. Control MUST be INFORCE !! USA !!
But in Kota Kinabalu, people did spot UFO there but where did it come from? Its going to space meaning there should be a passage way under the Mount Kinabalu via Sea shore line. Just like in Sarawak Caves, there are 180 miles of tunnle system with a large space in it.
Believe it or not, it depends on people..
Like people believe in Solid Earth same as people believed in Hollow Earth and some FLAT EARTH !!! Link to flat earth : http://www.theflatearthsociety.org/forum/i...hp?topic=1324.0

In Asia, story of the inner world is told by generation without suppression but in europe, it a different stories. 
Like Irish they also subject to certian supression by "Club"

The flat earthers would go for the throats of hollow earthers and we should let them slug it out. You can't have flat and hollow at the same time. It will be entertaining to watch.

It's not commonly heard that there's underworld. there's no backup too the underworld don't exists.

other than humans, there's other creatures on sea, land and grounds. however does that covers all the mysteries unfold? there's still more of mystery creatures to be discovered.

from some prophecies and traditions, there's still strange creatures to come out from hidden places. Thus, other dimension or space than Earth isn't impossible.

There are holes on the poles and having hole on Arctic obviously the ocean continues on other side of the hole in inner earth.

Dimension of the holes are :inner span(center of the hole)is 95 NM wide and the diameter of the rim or the start of downward curvature is 1400 NM cca.
Earth crust close to the poles is 1050 NM thick.

Why we do not see those holes on many images from the space?
Firstly because there are not available high resolution images for great public(Google Earth etc)
Even if good photo of polar regions is seen by inexperienced eye hardly any hole will be distinguished.The center of the hole is always covered by thick cloudiness(temperature diff) and the passage of earth curvature to hole curvature is so slight that hardly visible.Example is down bellow:



and our planet's cross sections is probably as shown down bellow except that most probably the thickness of the crust in equatorial region is bigger:

just because there's an a hole there, doesn't mean it's empty. If the theory is true, then sea water would be both inside and outside of the crust.
