What happens if a hydrogen bomb explodes in an iron ball 10 kilometers thick?

The emergence of gunpowder has completely changed the war history of human civilization, and gunpowder is one of the four great inventions in ancient China. After the birth of gunpowder, the ancient Chinese civilization can be said to be the most powerful country in the world, but it is a pity that gunpowder technology was introduced to Europe, and European scientists surpassed us after more research and exploration.

The power of gunpowder is undoubtedly huge. Its explosion can break mountains and rocks, and blast ordinary iron objects. But if the thickness of the iron object is relatively large, the explosive is also powerless. With the continuous progress of human science and technology, the most powerful weapon of mankind has appeared, which is the nuclear bomb.


Nuclear bomb is developed on the basis of Einstein’s mass energy equation theory. Through nuclear fission or fusion, it uses the powerful energy released by the lost mass to cause great damage to the surrounding space. The appearance of nuclear bomb has once again made a qualitative leap in human civilization. It has replaced fossil energy and become the most powerful energy for human beings.

Of course, there are two applications of nuclear energy, nuclear fission and nuclear fusion, and their representative works are atomic bomb and hydrogen bomb. Because the power of nuclear fusion far exceeds that of nuclear fission, the power of hydrogen bomb is incomparable with that of atomic bomb. After the development of hydrogen bomb, human beings have not used it in war, but have carried out relevant nuclear explosion experiments in some places.

The scene of hydrogen bomb explosion makes people feel shocked and afraid. Once this kind of destructive weapon with infinite power is used in reality, the damage will undoubtedly be very terrible. Therefore, nuclear bomb, a strategic weapon, cannot be used easily, and its greater role is deterrence.


Whether it’s gunpowder bombs or hydrogen bombs, they want to have a strong destructive force on the surrounding space, so the prerequisite is that the energy generated by the explosion can be released. If the energy can’t be released, it will not cause terrible damage to the surrounding environment.

A friend once raised such an interesting topic: what would happen if a hydrogen bomb was placed in an iron ball with a thickness of 10 kilometers and then detonated? I believe many friends have seen some explosion-proof cans in some important places. They are filled with some inflammables and explosives.


Once the object in the explosion-proof tank explodes, the thick explosion-proof tank can restrain the energy generated by the internal explosion. Even if it can’t be restrained, generally speaking, the upper part of the explosion-proof tank is not sealed. The purpose is to release the internal energy upward once the explosion occurs, so as to only damage the upper space.

Therefore, we will see that the explosion-proof tank directly above the need for a larger space, that is a buffer space. If the explosion energy inside the explosion-proof tank is released upward, there will be no energy release in the other three directions, so it will not damage the surrounding objects.

If the energy of hydrogen bomb explosion can be completely confined in a very limited space, it will also cause great damage to the surrounding environment and objects. So someone conceived an iron ball with a thickness of 10 kilometers. There is a hydrogen bomb in the center of this iron ball. The space is very small. If you know something about nuclear bombs, you should know that although the hydrogen bomb is extremely powerful, its volume is not large.


Can a 10 kilometer thick iron ball restrain the energy produced by the explosion of a hydrogen bomb? The answer is yes. We need to know that although the density of the material iron produced by human science and technology is not particularly large, as long as the thickness increases, the defense force is very terrible. Ordinary TNT even ordinary explosion-proof tank are not broken, even if it is more powerful TNT, if it is more than one meter thick explosion-proof tank, it is also difficult to shake.

Therefore, the bank’s vault and other important places have very thick iron gates for defense. They are not afraid of the threat of TNT explosion. Even with our current nuclear power, some facilities with better explosion-proof capability can not be damaged. An iron ball with a thickness of 10 kilometers, not to mention a hydrogen bomb, even ten can temporarily restrain the energy.


In this very limited sealed iron ball, once the hydrogen bomb explodes, because the energy can not be released, the scene will be very spectacular. As we all know, the nuclear energy mode of nuclear fusion applied by hydrogen bomb is the most powerful energy release mode of nuclear energy. In the process of nuclear fusion, atomic fusion loses mass and releases powerful energy.

If the surrounding space is vast, the energy will be released quickly and produce strong destructive power. However, if it is confined in a very limited range and the energy can not be released, it will produce tens of millions of degrees of high temperature and millions of atmospheres. Under this condition, all kinds of materials produced by fusion may continue to fuse in the limited space, and other changes may occur.

Seeing this, many people think of the nuclear fusion mode inside the sun. Tens of billions of hydrogen bombs are exploding inside the sun all the time, and the intensity is unimaginable. At this time, the internal temperature of the sun has reached tens of millions of degrees, and the air pressure has 250 billion atmospheres. The nuclear fusion inside the sun can form this environment. An important reason is that the energy generated by nuclear clustering is tightly bound by the solar shell and cannot be effectively released.


In such a high temperature and high pressure environment, hydrogen becomes helium, and helium continues to fuse until the hydrogen is consumed. The outer shell of the sun can no longer bind the inner core, and the outer part expands and collapses, and the inner fusion energy is released, resulting in a super new star explosion. Of course, with the mass of the sun, it is difficult to have a supernova explosion in the end, the shell expands, and the core collapses to form a white dwarf.

The iron ball with a diameter of 10 kilometers can be imagined as an infinitely reduced version of the sun. Once the hydrogen bomb inside it explodes, the huge energy generated instantly will be bound by the iron ball, which will also form a transient nuclear fusion environment. It’s just that the environment won’t last as long as it does inside the sun. The reason is because of the material.


You know, hydrogen bomb is confined in a very small iron ball, the explosion will produce tens of millions of degrees of high temperature, such a temperature is not yet any material can be bound. The melting point of iron is only 1538 degrees Celsius. Once the hydrogen bomb explodes in the center of the iron ball, the high temperature produced will continuously melt iron from the inside. However, because the thickness of the iron reaches 10km, it takes time to melt. Moreover, the energy generated by a hydrogen bomb explosion is not enough to melt a 10km thick iron ball.

Is the above topic very interesting? Of course, this is just a hypothesis. In fact, in reality, it is impossible for us to produce an iron ball with a thickness of 10 kilometers. What is the quality of such a thick iron ball? Welcome to comment below.
