The great catastrophes can cause mankind to perish

The impact of meteors, nuclear war, and artificial intelligence are the top three threats threatening to eliminate humanity.

The impact of meteors

There are many pieces in the space that collide with the Earth every day.

According to Gizmopod, a lot of space debris collides with the Earth every day. Most of them are small, but some cases are quite large in size. It is estimated that an asteroid must have a minimum size of 1.6 km to erase all humanity. If a collision between a meteorite and the Earth occurred about 65 million years ago that caused the dinosaurs to become extinct, this could also happen to humans.

Nuclear war

If 1000 atomic bombs explode, we will kill the entire world population.

Researchers said that if the global nuclear war broke out and 100 atomic bombs were put into use, the Earth would undergo a nuclear winter with a record low temperature, causing serious impacts. Important to survivors. If 1,000 atomic bombs explode, they will kill the entire world population.

Super volcanic eruption

Super volcanic eruptions will prevent sunlight for many years like nuclear winter.

Under Yellowstone National Park, the US is a super volcano ranging from 55 to 72km. Its most recent eruption was 640,000 years ago. This erupting volcano will produce two billion tons of sulfuric acid, while blocking sunlight for many years like nuclear winter.

Overpopulation

If the population keeps rising without stopping, more people will die due to lack of food and clean water.

The world population is increasing. Many people think the problem will be overcome in the next 50 years, when scientists find ways to more effectively use the Earth's limited resources. If the population growth process does not stop, billions of people will die due to lack of food, clean water and war.

Climate Change

Earth's climate is changing, partly because of human impact.

The climate on Earth is changing, in part because people use fossil fuels, emitting greenhouse gases. The rise in temperature caused many extreme weather events, droughts, lowland flooding, which in turn affected the economy and politics.

Destroy the ecosystem

Each year, about 300,000 species of organisms disappear due to human activity.

About 300,000 species of organisms disappear each year due to human activity. At this rate, people are gradually causing the 6th major extinction event. If not enough species are left on Earth to help maintain life, humans are likely to disappear next.

Disease

Disease will become increasingly scary when they can resist antibiotics.

People move around the world every day. If an untreatable deadly disease breaks out, it will spread faster than we stop. Resistance to antibiotics is also very scary, making the disease increasingly dangerous.

Biological warfare

Biological warfare will carry the spread of pathogenic bacteria until people can respond to it.

Some variants of avian influenza viruses or human-made anthrax for war can be more dangerous than nuclear bombs. They will infect most of the world's population before we can get back on hand.

Risks of particle accelerators

The scientific world ensures that the risks of particle accelerators are not strong enough.

Since the European Nuclear Research Organization (LHC) of the Swiss Nuclear Research Organization came into operation, many people fear it will create a small black hole, suck the Earth in and destroy it all. both. However, the scientific community ensures that this risk cannot occur because the particle accelerator is not strong enough.

Black hole

If the black hole is near the Sun, it will disrupt the orbits of the planets.

Scientists estimate there are about 10 million black holes in the Milky Way. If one of these black holes is too close to the solar system, it will disrupt the orbits of the planets, and suck us all into it.

Gamma ray explosion

The explosion of gamma rays from the fusion of two stars will produce tremendous energy, which can destroy the Earth.

The gamma-ray burst originates from the fusion of two collapsing stars, producing about one million billion times more energy than the Sun. If lying on the path of gamma-ray beams, the Earth's atmosphere will heat up, the ozone layer is destroyed, causing people to lose their protection against UV rays, causing a mass extinction event.

Artificial intelligence

40 years is the time when artificial intelligence will surpass humans.

Computer scientists estimate that the time when artificial intelligence is smarter than humans will come in about 40 years. The problem is that robots are then on the side of rebellious people.

Alien invasion

Up to now, we still do not know if we are alone in the universe.

Up to now, people do not have any contact with aliens. We don't even know if we are alone in the universe. However, we cannot rule out the possibility that aliens attack the Earth to invade resources, or destroy the Earth to open highways across space.

Sun storm

Solar Storms operate with an 11-year cycle.

The Sun operates over a period of 11 years. It erupted very loud flames at the time of the greatest activity, causing the phenomenon of solar storm. It is estimated that half of the US will lose power and millions of people could die if a strong solar storm occurs.

The sun is open

Five billion and a half years, the Sun will be big enough to swallow Earth.

The Sun is slowly expanding every day. After about 5 billion years, it will become a giant red star, big enough to swallow Earth.
