Assuming that this internal sun is running on regular fusion that's used by the sun, we'll have a ball consisting mostly hydrogen at a very high temperature surrounded by an atmosphere that contains oxygen. Last that I've heard, a hydrogen and oxygen mixture is very flammable and a fusion reaction is more than enough to spark an ignition. The resulting fireball will consume all available oxygen molecules. Any oxygen breathing organism would be dead in such an environment due to lack of breathable oxygen. The same goes for any combustion based machinery like airplanes as well.

Answers:
1. Based on this information on hydrogen, a hydrogen fire can start at 4% of the total mixture. Based on this information about the sun, it is close to 75% hydrogen by mass. Plenty of hydrogen to go around for a continuous fire.

2.A normal fire burn in a process called combustion to release energy. The sun doesn't really burn, it under goes a process called nuclear fusion to release energy. One is a chemical reaction,the other a nuclear reaction.

3.What does ozone have to do with all this? Ozone isn't used in respiration. It is even harmful when it comes in direct contact with living creatures. Ozone doesn't have anything to do with magnetic fields, it is created in a reaction between oxygen gas and ultraviolet light. Ozone is also flammable so it doesn't protect against combustion.

The problem with this theory is that none of the visitors from the surface would have survived their visit since they are not prepared for this environment in the first place.

We're talking about humans here, they don't spontaneously mutate features to survive a different environment instantaneously. Drop a person in those environment, he'll be more or less dead immediately. Just because a species can live in a hostile environment, doesn't mean that you can.

While this already out of topic, do you have links to these so called records about people living for hundreds of years?
This says otherwise.

There's a section on centenarian on the page that I've shown. They are not an impossibility. People living hundreds(200+) of years on the other hand are undocumented. You specifically said hundreds of years.

After rereading your post, did you mean to say they are a lot of people living to hundreds of years or living to pass a hundred in the past? If you were referring to people living to around a hundred, they've always been around. Based on the link I gave in that post, there's even more people living to pass a hundred these days compared to the past. It doesn't prove anything.

In another word, there's nothing to back up your statement where you mentioned about records of people living longer in the past.

It wasn't specified clearly in that post but what does people living longer in the past prove?

The planet Venus and Mars doesn't seem to support your theory about size of planets and rotational speed. Based on this, venus' mass is about 0.815 of Earth's mass and Mar's mass is 0.107 of Earth's mass. Earth is bigger than both of these 2 planets. Mars is much smaller than Venus. A Venusian day is about 243 earth days while a Martian day is about Earth 1 days.

I laugh at your small impact craters and present to you-The Giant Impact Hypothesis. The shortened version of this theory is that the moon was formed when a Mars sized object collided with the earth. An impact that size is bound to deform or create a hole in the side of the planet if it was hollow.

Seeing as how the moon has 0.01 the mass of earth and Mars is around 0.1 the mass of earth, the earth gained mass in the violent exchange. This would have resulted in a lop sided mass distribution on the planet which destabilize your rotating hollow sphere.

Based on this, most of the energy from the impact was converted to angular momentum which increased the speed which the planet was revolving instead of linear momentum which would have altered the movement of the planet through space..

If you are not supposed to use logical explanations to explain something, how do you prove your theory is correct? Spam pages and pages of stuff so that people agree with you just to shut you up or wait until no one care about the thread anymore so that you can declare yourself the winner. If you don't want to have a discussion, don't post your stuff on a forum.

The part about science where a theory can be disproved is what makes science great. Wrong information can be removed.

What is a quantum mechanic shop?

Fun fact about the Arctic polar cap, this submarine actually went under it and passed the North Pole.

I didn't mention anything about a hole there in that post, did I? I only mentioned about the sub going under the polar cap and passing the north pole.

It is related, you've already stated what I wanted to convey and if someone wanted to say that the hole can be opened and closed, the sea water rushing in will cause the world's sea level to drop.

Mirages are not rare. All you need to get one is layers of air with different temperature for it to happen. With the North Magnetic Pole in the area, no magnetic compass will work correctly. These are naturally occurring phenomenas that has nothing to do with your so called hole.

What's is the purpose of showing off such a large map? It doesn't show anything relating to you so called hole at all.

Look at the first article above, the part that has been put in bold. It say solid earth, not hollow earth.

Next article in you've posted is related to plate tectonics. There's no way plate tectonic would work with your hollow earth theory unless the continental plates can float on air inside your hollow earth.

You've just disproved the hollow earth theory again. Do you even bother to read and understand what you've posted?

Given the number of irrelevant post by the TS, I doubt this thread will remain open when the moderators are notified.

There's plenty of single cell organisms that are not hollow inside.

There's no comparable living creature to the planet so this generalisation doesn't work at all.

And with this post, we now know the motivation for the TS' obsession with this particular subject. A heaven on earth where the only entrance condition is being able to get there. Unfortunately Shangri-La is a work of fiction created in the 1930s and Shambhala which Shangri-La is based on has a karma related entry method. There's no mention of these places as being underground.

That's explained somewhere within the 13 pages of text. Something about centrifugal force keeping the structure stable.

The reason why this thread expanded to such a length is due to the thread starter's faith that there exists a paradise within the planet. A place where people don't get sick, old and such. Since he doesn't have the means to prove such a thing, he hoped to get more believers so they can start an expedition to find this place and live there. The thread more or less died after that was pointed out.

The are a couple of holes with your theory on pressure maintaining the structure of your hollow earth. Have you seen a balloon hold it's shape if its opening was not sealed? You have a hole at each of the planet's poles.

Centrifugal force may explain how a hollow structure can be maintained. It can't explain how it can form a hollow shell. While it is possible for elements to enter a stable orbit around a forming planet, it is very unlikely in this case for a few reasons.

The item orbiting the planet would have to have an exact velocity at a perpendicular angle to the planet. Too slow and it falls into the planet. Too fast and it leaves orbit. Have the wrong angle, the item will either fall onto the planet or fly into space. The odds of entering a stable orbit isn't that good.

In a forming planet, the mass of the planet increases overtime. Items previously in orbit will fall into the planet as their velocity will not be sufficient to provide the centrifugal force needed to remain in orbit. This will add more mass to the planet. Resulting in more items falling out of orbit and so on. As the planet continues to get larger, it starts having an atmosphere as its gravity is capable of holding gas molecules on it surface. An atmosphere causes air friction to anything that moves within it. This results in more items falling onto the planet.

The Sun or stars are made of hydrogen. The lightest element in the universe. Based on the reasons above, hydrogen would probably be the last elements to be captured by a planet. This makes it very unlikely for the planet to have a core made of hydrogen. No hydrogen, no mini sun.

Naturally occurring mini suns don't exists for a reason. A star can only have a fusion reaction if its gravity is sufficient to cause hydrogen atoms to fuse. You can fill around a hundred earth inside our sun. Gas giants like Jupiter have the necessary elements for a star but it's still not big enough for fusion to occur.
