What will happen if all the nuclear bombs in the world fire at the same time?

We can summarize it with a brief sentence - all explosive nuclear bombs have nothing left.

According to the statistics of the US Science Federation in 2017, there are 14,900 nuclear warheads in the world. Imagine if all 14,900 modern nuclear warheads were fired, what would happen?

The power of a B83 bomb

One of America's most modern nuclear weapons is B83 . It could cause an explosion equivalent to 1.2 million tons of TNT, generating energy at about 5 million Jun and having the power to destroy with 79 bombs dropped on Hiroshima in 1945.

B83 explosion will create a hole 420 meters wide and 92 meters deep - according to nuclear history researcher Alex Wellerstein.

A B83 bomb.

The explosion will immediately create a giant fireball within 5.7 square kilometers, with temperatures up to 83.3 million degrees Celsius.

By using only 50% of the energy, it could create a huge pressure, causing all buildings within a radius of 16.8 kilometers to be leveled.

The explosion created a giant fireball.

Next, the 35% of the explosion's energy will cause thermal radiation to cause everyone within a radius of 420 kilometers to be simulated at level 3 (however, they only feel pain for a fraction of a second because of every god Sutra will be burned for a moment).

Finally, radioactive dust and ions . Assuming that there was no wind at that time, the area around the 20.6 kilometer explosion would be badly affected. 50 - 90% of people will die immediately due to radiation exposure.

All buildings within a radius of 16.8 kilometers are leveled.

When all exploded at the same time

Although all nuclear warheads in the world are not as modern, let's assume all bombs are as powerful as B83. At that time, we will have about 13,800 B83 fruits. What happens when they explode at the same time?

First, the explosion will destroy 94km of land immediately. 232,000 square kilometers of infrastructure will be blown away by the pressure created. This means that 295 municipalities the size of New York City will turn into ash.

Several hundred giant cities will be burned down.

Next, a 79,000 square kilometer fireball will burn everything it touches, and kill anyone standing within a 5.8 million km radius around it, meaning everyone in a large area of ​​3,700 London city will die.

Eventually, the radioactive ion and ion cloud will poison an area of ​​284,000 square kilometers and make anyone alive radioactive.

Hundreds of millions of people (even billions of people) will die in the first hour.

In short, hundreds of millions of people (even billions of people) will die in the first hour. However, it has left a long-term harm.

The other is a long winter

When a nuclear explosion occurs, the radioactive dust will fly up to the upper atmosphere and lower the planet's temperature.

A theoretical nuclear winter is quite similar to the ice ages that had taken place in the past, except that one breath of air can make you sick and die. So, how many nuclear fireballs do you need to cause a long winter?

The cold will destroy everything.

One study suggested that 100 bombs that had fallen on Hiroshima could release enough carbon fragments to create a small nuclear winter.

The global temperature will decrease by at least 1 degree C. Therefore if all the nuclear warheads explode, an eternal night will cover the Earth for centuries and destroy life on it.

Only plants adapted to the harshest environments can survive and rise to the top of the food chain.

A great extinction will take place, maybe people will completely disappear. The remaining species must live in a world with very heavy radioactivity.

Life on Earth will disappear.

Of course, the above is just a hypothesis of scientists. The reality may be far more formidable, so let's hope that it never happens.
