We can summarize in a single sentence – all nuclear bomb explosion is nothing left at all. According to the statistics of the Federation of American Scientists in 2017, the world now has 14,900 nuclear warheads. Imagine if all 14,900 nuclear warheads fired modern, what will happen?
The destructive power of the bomb B83 1
One of the modern nuclear weapons of the US today is B83. It can cause an explosion equivalent to 1.2 million tons of TNT, creating energy on Jun 5 million and could crash by 79 bombs had been dropped on Hiroshima in 1945. B83 when the explosion will create a hole 420 meters wide and 92 meters deep – according to researcher Alex Wellerstein nuclear history.
The blast instantly create a giant fireball within 5,7km square, with temperatures up to 83.3 million degrees C. Just use only 50% of energy is that it can create a huge pressure, making everyone works in the 16.8-kilometer radius were razed.
Next, 35% of the energy of the explosion will cause thermal radiation makes everyone in a radius of 420 kilometers degree burns 3 (however they feel pain only in a fraction seconds because every nerve business will burn for a while). Finally the fallout and ions. Suppose at that time there was no wind, the sun around the blast area of 20.6 kilometers will be hit hard. 50-90% of people would die instantly due to radioactive contamination.
When they all explode at once!
Despite all nuclear warheads are not the modern world alike should let us suppose all bombs are devastating as B83. Meanwhile, we will have about 13,800 results B83. What happens when they explode simultaneously? First, the explosion will destroy square 94km inland immediately. Square 232.000km infrastructure will be blown by pressure flow generated. This means the 295-sized cities such as New York City will be reduced to ashes.
Next, a fireball sized square 79.000km will burn everything it touches, and kill anyone standing within 5.8 million km radius around it, meaning that everyone in a wide region by 3700 the city of London will die. Finally, the radioactive cloud would ion poisoning and a large area and caused square 284.000km anyone alive radioactive contamination.
In short, hundreds of millions (even billions of people) will die within the first 1 hour. However, it left more long-term effects.
The rest is a painful long winter!
When nuclear explosion occurs, the radioactive dust will fly up to higher levels of the atmosphere and lowering the temperature of the planet. A nuclear winter theory is quite similar to ice ages had occurred in the past, except for a job is just inhale the air that you can ill and died instantly. So, how many nuclear fireball to cause a painful long winter?
One study showed that of 100 Hiroshima bombs are falling each can release enough carbon fragments to form a small nuclear winter. Global temperatures will decrease at least 1 degree C. So if the entire nuclear warheads and detonate, an eternal darkness will cover the earth took centuries and destroy life on it.
Only plants adapted to the harshest environment can survive and soared to the top of the food chain. A greatest mass extinction will occur, can the human will completely disappear. The remaining species must live in a world very severe radioactive contamination.
Of course, everything above is just assumptions of scientists. The reality may be even more formidable, so let us hope that it never happens.
