Why the atomic bomb inevitable?

As technology evolves in terms of equipment (digital or physical) and machines, a major shift in human weaponry is also taking place. First-world countries like the United States, Russia, Japan, and China are well recognized for their technical military advantages. As a result of other nations claiming their borders, certain nations are embroiled in territorial disputes. Some governments are preparing and developing human guns and weaponry in order to protect their territory if a conflict breaks out. Other possibilities have evolved as a result of other nations' territorial aspirations, such as the prospect of a third global war.

So, just what is an atomic bomb? Who created this type of human weapon, particularly the atomic bomb? What is the scientific construction of an atomic bomb? How does it inflict such devastation? And what steps should governments take to avoid misunderstandings with other countries? To begin, J. Robert Oppenheimer, dubbed the "Father of the Atomic Bomb," was the first person to demonstrate the atomic bomb. The Trinity Test, which took place on July 16, 1945, in a remote desert location outside Alamogordo, New Mexico, was the first atomic bomb to be safely exploded. It ushered in the Atomic Age by erupting a gigantic mushroom cloud 40,000 feet in the air.

The Trinity test of the Manhattan Project was the first detonation of a nuclear weapon, which led J. Robert Oppenheimer recalling the Hindu verses: "If the radiance of a thousand suns were to burst at once into the sky, that would be like the splendor of the mighty one "...

An atomic bomb, also known as an atom bomb, is created by the abrupt release of energy caused by the separation, or nuclear fusion, of the nuclei of a heavy element such as plutonium or uranium. Only two nuclear weapons have ever been deployed in battle in our history, both by the United States on Japanese nationals at the conclusion of WWII. On August 6, 1945, a uranium gun-type fission bomb code-named "Little Boy" or "the bomb at Hiroshima" was detonated over Hiroshima, Japan. On August 9th, a plutonium implosion-type fission bomb code-named "Fat Man" or "the bomb at Nagasaki" was detonated over Nagasaki, Japan.

Andrew Furlong of the Institute of Chemical Engineers argues that we can't create a nuclear bomb without fissile material. The required material for a typical thermonuclear unit is plutonium or enriched uranium. Uranium, a naturally occurring heavy metal, comes in two varieties: 238 and 235. Both are radioactive and can decay into other elements over time, but only the latter may be divided by neutrons forcibly. It is the basis for a nuclear weapon. When an atom divides, it emits energy and more neutrons, which can be used to separate more atoms. A chain reaction occurs when enough atoms split, culminating in a bomb explosion.

To make a bomb, natural uranium must be treated to concentrate the 235 isotopes within it. Natural uranium, on the other hand, is frequently composed of the 238 isotopes, which reflect any neutrons that touch it, rendering it unsuitable for use in bombs. Because the two isotopes are chemically identical, no standard extraction procedure can tell them apart. And this is when the real problems begin. For every 25,000 tons of uranium ore, only 50 tons of metal are removed. Uranium 235 accounts for less than 1% of the total. Instead, uranium is reacted with fluorine, heated to generate a gas, and decanted via thousands of fine porous barriers.

To build a nuclear reactor, uranium must be enriched to contain 20% uranium 235. In the case of nuclear weapons, the figure should be closer to 80 or 90 percent. To construct a bomb, you just need around 50kg of enriched uranium - the critical mass. Otherwise, there is no explosion as a result of the chain reaction. Plutonium could be used instead. According to Keith Barnham, a physicist at Imperial College, this is the preferred material because it provides considerably lighter weapons that can be put on missiles. Nuclear reactors produce plutonium as a byproduct, and a weapon requires just approximately 10 kg. An typical power plant needs about a year to produce enough plutonium to extract it from the fuel, and expensive reprocessing facilities are required.

When you have the fundamental materials, life becomes easier. The bomb will detonate once the critical mass of uranium or plutonium is reached. To begin with, in order to prevent exploding in the hands of its owners, the bomb must retain the metal divided into two or more parts. These sub-critical masses need to be thrown together until the weapon is in place and ready to fire - and the weapon will fire. These sub-critical masses just need to be tossed together until the bomb is in place and ready to detonate, which is easily accomplished using conventional explosives. Following that, the chain reaction, explosion, and well-known mushroom cloud take care of themselves.

On the other hand, there are several impacts that have the potential to ruin many areas of our planet, including the economy, industry, and, most crucially, humanity. The repercussions of using one of the nuclear weapons would be disastrous. The core of a nuclear explosion can reach temperatures of several million degrees Celsius. The resultant heat flash vaporizes all human tissue across a wide area. People inside or otherwise sheltered will be indirectly killed by the explosion and heat impacts when buildings fall and all flammable objects burst into flames. Many people who escape the initial heat wave will expire as the atmosphere becomes devoid of oxygen.

There will be an ever-increasing number of immediate survivors beyond the zone of absolute annihilation. The vast majority of them, on the other hand, will perish from deadly burns, become blinded, bleed profusely, and suffer significant internal injuries. The nuclear fallout will damage survivors in a matter of days. Radiation-induced malignancies, which can develop over a period of up to twenty years, will afflict a substantial number of people. Nuclear bombs harm the atmosphere and ecology on a scale unparalleled by any other weapon: the Red Cross estimates that a billion people might starve as a result of global nuclear war.

To conclude, the atomic bomb's composition, components, and production method are all complex. Developing such a weapon, on the other hand, is exceedingly dangerous because it has the ability to exterminate the entire human species as well as the entire world. We can say that the discovery of the atomic bomb transformed people's interest in science, but it is exceedingly dangerous. Using the atomic weapon to address disputes between countries will not address their problems; instead, diplomatic alternatives should be pursued. It is critical to remember that the only option to completely eliminate nuclear dangers is to destroy all nuclear weapons from the planet. By doing so, we will protect the entire human species against the possibility of something similar happening.

I’ll never understand why humans manufacture weapons just for the sole purpose of killing other humans. One can argue that the initial objective was to protect territories but it gone far beyond that now. Weapons are made for profit and the world can never be peaceful, otherwise, weapon manufacturers would have to go out of business

I agree with this statement. Bomb is made to protect territories in the first place, but we used bomb to scare people and acquire lands. War becomes a business venture rather than protecting sovereignty. !PIZZA

I was born in 1947. The first bomb was set off only two years before my birth. In the late 40s and early 50s there was a pervasive darkness, almost a hysteria, about developing a bigger bomb, a better bomb. It's hard to imagine anyone would think such a 'race' could be won. It reminds me of the laboratories developing virulent viruses today. The hubris of believing such a thing can be developed, and controlled.

I think of all the great scientists whose discoveries paved the way for the bomb. Becquerel, Curie, Fermi. All so bright, and so foolish. Everyone discovering a little piece of the puzzle. And here we are, living with the legacy of their great gifts.

I'm not a scientist. I'm not a philosopher. Just a person shaking her head. Will our species (will our planet) be able to survive our ingenuity?

I think it goes down to pride. Humans are generally prideful being. With such characteristics, we became foolish that we forgot to find a greater cause rather than satisfying our needs of success and achievement. Going back to bomb and viruses, humans really believe that it can be controlled, but I think there will always be a case that we can't.

It is ironic but it is true. Only time will tell to what extent a revolutionary idea can be good or a foolish act.

If our ingenuity is used to benefits humanity and Earth, we will survive, but if we focus on business and profit, we will not. It is always ironic. Our ingenuity be fall us. !PIZZA
