EXPERTS have revealed what would happen if all the nuclear weapons on our planet detonated at the same time.

A YouTube account by the handle of ‘Kurzgesagt – In a Nutshell’ shared a video discussing the impact of nuclear weapons.

Specifically, the content creator detailed what would happen in the unlikely scenario that all nukes on Earth detonated at the same time.

In 2019, when the 8-minute-long video was created, there were approximately 15,000 nuclear warheads around the world.

The video also shared that there are a total of 4,500 cities, or urban areas, with at least 100,000 inhabitants.

To destroy one of these cities would take three nuclear warheads; to destroy all of these cities would require 13,500 bombs in total.

That number of bombs could wipe out more than three billion people, or roughly half of humanity in an instant, per the video.

And that still leaves around 1,500 warheads remaining. However, as of 2022, there are approximately 13,080 nukes in the world.

This means that 140 cities could survive in today’s day and age.

The impact

The power of 15,000 warheads is the equivalent of 3 billion tons of TNT.

If all of these warheads were to be detonated at the same exact time, it would first create a fireball 50 km across.

This would, in turn, create a blast wave that would flatten and kill everything in a 1,865-mile radius.

The explosion would be heard around the world and the pressure wave would circle the Earth tens of times for several weeks.

What happens next?

Next, millions of tons of incinerated materials would catapult into the atmosphere, causing a mushroom cloud that would reach the edges of Earth’s stratosphere.

Down on Earth, a fire would rage at the location of the explosion – in this case, the Amazon rainforest – that burns down the continent.

If that isn’t bad enough, the radiation from the detonation site would kill every living thing within the blast radius.

Much of the fallout is also carried into the atmosphere via the mushroom cloud and carried throughout the world.

And while, the amount of radiation around the world wont be enough to wipe out humanity, cancer rates would skyrise.

The bad news continues: the ash cloud would lead to a ‘nuclear winter’ which would lower global temperatures for a few years.

An even-worse outcome

The video also proposes a second scenario in which humans mine every last bit of uranium to build as many bombs as they can.

In this catastrophic situation, nuclear winter would cause temperatures to drop below freezing for decades.

There would be no sunlight reaching the Earth’s surface due to the mushroom cloud, and all life would be extinct.

Following this worst-case scenario, it would take millions of years for life to reemerge on the planet.

“After just a few million years, the wounds of the explosion have healed. Life is thriving, arguably, even more so than when humans were around.”
