The emergence of gunpowder has completely changed the history of war in human civilization. The power of gunpowder is undoubtedly huge. Its explosion can open mountains and crack rocks and explode ordinary iron objects. But if the thickness of the iron object is relatively large, the explosive is also powerless. With the continuous advancement of human science and technology, the most powerful weapon of mankind has appeared, and that is the nuclear bomb.
The nuclear bomb is researched on the theoretical basis of Einstein’s mass-energy equation. It uses the powerful energy released by the lost mass through the fission or fusion of the atomic nucleus to cause huge damage to the surrounding space. The emergence of nuclear bombs has once again brought about a qualitative leap in human civilization. It has replaced fossil energy and has become the most powerful energy source for mankind.
Of course, there are two applications of nuclear energy, nuclear fission and nuclear fusion, and their representative works are atomic bombs and hydrogen bombs. Since nuclear fusion is far more powerful than nuclear fission, the power of hydrogen bombs is incomparable to atomic bombs. After humans have developed hydrogen bombs, they have not been used in wars, but related nuclear explosion experiments have been conducted in certain places.
The explosion of the hydrogen bomb makes people feel shocked and scared. Once this infinitely powerful destructive weapon is used in reality, the damage it will bring is undoubtedly very terrifying. Therefore, the strategic weapon of nuclear bomb cannot be used easily. The greater role is deterrence.
Whether it is gunpowder bombs or hydrogen bombs, if they want to produce powerful destructive power in the surrounding space, the prerequisite is that the energy generated by the explosion can be released. If the energy cannot be released, then naturally it will not cause terrible damage to the surrounding environment.
A friend once brought up such an interesting topic: if a hydrogen bomb is placed in an iron ball with a thickness of 10 kilometers and then detonated, what will it be like? I believe that many friends have also seen some explosion-proof tanks in some important places, and they contain some flammable and explosive materials.
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 cannot be restrained, the top of the explosion-proof tank is generally not sealed. The purpose is once it happens. The explosion can release the internal energy upwards, thereby only causing damage to the space above.
Therefore, we will see that a relatively large space is needed directly above the explosion-proof tank, which is a buffer space. The explosion energy inside the explosion-proof tank is released upwards, so there will be no energy released in the other three directions, so that it will not cause damage to surrounding objects.
The two principles are that if the energy of a hydrogen bomb explosion can be completely confined in a very limited space, it will also cause huge 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. Anyone who knows about nuclear bombs should know that although the power of the hydrogen bomb is immense, its volume is not large.
So can an iron ball with a thickness of 10 kilometers restrain the energy generated by the explosion of a hydrogen bomb? The answer is yes. It is necessary to know that although the density of iron, the material produced by humans’ current technology, is not particularly large, as long as the thickness is increased, the defensive power is very terrifying. Ordinary TNT can’t burst even ordinary explosion-proof tanks, even if it is a relatively powerful TNT, if it is an explosion-proof tank with a thickness of more than one meter, it is also difficult to shake.
Therefore, the bank’s vault and some other important places have very thick iron gates for defense, and they are not afraid of the threat of TNT explosion. Even the power of our current nuclear bombs cannot cause damage to some facilities with better explosion-proof capabilities. And an iron ball with a thickness of 10 kilometers, not to mention a hydrogen bomb, even ten of them can temporarily restrain the energy.
In this very limited sealed iron ball, once the hydrogen bomb explodes, because the energy cannot be released, the scene will be very spectacular. We all know that the nuclear energy mode of nuclear fusion applied by the 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, these energies will be released quickly and produce powerful destructive power. But if it is constrained within a very limited range and the energy cannot be released, then tens of millions of degrees of high temperature and millions of atmospheres will be generated. Under these conditions, various substances produced by fusion may continue to fuse in a limited space, resulting in other changes.
Seeing this, many people thought of the nuclear fusion mode inside the sun. Hundreds of billions of hydrogen bombs are exploding inside the sun at all times. The intensity is beyond our imagination. At this time, the internal temperature of the sun reached tens of millions of degrees, and the pressure was 250 billion atmospheres. The nuclear fusion inside the sun can form such an environment. An important reason is that the energy generated by nuclear clustering is firmly bound by the outer shell of the sun. Cannot be released effectively.
Under such a high temperature and high pressure environment, hydrogen element fused into helium element, and helium element continued to fuse, and the cycle continued until the hydrogen element was consumed, the outer shell of the sun could no longer restrain the inner core, the outer part continued to expand and collapse, and the inner nuclear fusion energy was released. Come out, a supernova explosion occurs. Of course, with the mass of the sun, it will be difficult for it to explode in the end, the outer shell expands, and the inner 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 in an instant is bound by the iron ball, which will also form a short-term nuclear fusion environment. It’s just that this environment won’t be maintained for a long time like the inside of the sun. The reason for this is due to material issues.
It should be known that the hydrogen bomb is confined in a very small iron ball, and the explosion will generate a high temperature of tens of millions of degrees. There is no material that can restrain such a temperature. 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 generated will continue to melt the iron from the inside. However, because the thickness of the iron reaches 10 kilometers, it is too thick, and it takes time to melt, not to mention the energy generated by a hydrogen bomb explosion is not enough to melt a 10 kilometers thick iron ball.
Is the above topic very interesting? Of course, this is just an assumption of ours. In fact, in reality, it is impossible for us to make an iron ball with a thickness of 10 kilometers. With such a thick iron ball, what level of quality will it achieve?
