Have you wondered how Earth sustains life?
Our atmospheric composition, closeness to the Sun and numerous other factors not only allowed life to evolve but helped thrive. The human race has been on Earth for over 2.8 million years. People, since the dawn of time, have been prophesying doomsday, weaving stories on how the world could end.
All things do come to an end. Nothing lasts forever. One day Earth will be uninhabitable.
As there are countless ingredients that created the perfect recipe to sustain life here on earth, there are also things that constantly threaten Earth. I’m talking about things that could wipe out the entire planet.
Life on earth won’t cease anytime soon until billions of years from now. But, that doesn’t mean there aren’t any vicissitudes of astrophysics that could wrench life out of this planet.
So, what could destroy our beautiful planet?
A group of scientists tried finding the answer. They came up with 12 things that are likely to destroy our world.
These 12 things are the situations that will bring about the day of reckoning. Let’s find out what they are:
- Catastrophic Climate Change
- Nuclear War
- Magnetic Reversal
- Asteroid Impact
- Gamma-Ray Burst
- Rogue Black Hole
- Solar Flares
- Vacuum Metastability Event
- Alien Life
- Artificial Intelligence
Let’s cover each of these topics in depth:
1. Catastrophic Climate Change
There’s no escaping the threat of climate change. Climate change is real. It’s not a hoax and it’s happening. Sooner or later it will affect us all. Greenhouse gas emissions are increasing at a higher rate than predicted. And, the world is getting warmer more quickly in response.
How Catastrophic Climate Change Could Destroy Earth
The rapid increase in global temperatures has been accompanied by upheaval in weather and climate. Many parts of the world are experiencing drastic changes in rainfall. More floods, intense rain, droughts and intense heat waves are following. Climate change is a grim threat to sustainable agriculture production, food security and economic growth.
2. Nuclear War
With all the outrage over nuclear weapons falling into the wrong hands, an all out nuclear war will inflict much severe catastrophe. The scientists concluded that usage of multiple “Super”, nuclear bombs can end the world.
How Nuclear War Could Destroy Earth
The atomic bombs yielding between 10 and 100 times as powerful as the ones dropped on Hiroshima and Nagasaki can wipe out the every living thing on earth. Nuclear fallout would be such a tragedy that could difficult to comprehend. Currently over 15,000 nuclear weapons are in possession of mankind. Even a minor nuclear conflict can inflict greater damage on the global climate and impact billions of people across the globe.
As far as the mankind history goes, fatal diseases have wreaked havoc on the human race. If you think pandemic can’t be a viable cause for obliteration, the Black Death in the 14th century killed one in every four Europeans.
How Pandemic Could Destroy Earth
At least 50 million lives were lost to the 1918 influenza outbreak. And, the outbreak took only two years to do such damage. In recent times, the West African Ebola virus epidemic (2013-2016) claimed thousands of people. SARS, bird flu and MERS; these are all potential pandemics.
4. Magnetic Reversal
Over the last 100 million years, 170 pole reversals occurred. Every few hundred thousand years, the magnetic field of the planet changes, as a result north and south poles flipped.
How Magnetic Reversal Could Destroy Earth
The last magnetic reversal occurred 781,000 years ago. The next one may not be that far from happening. European Space Agency found that the magnetic field is weakening 10 times faster than previously predicted. The magnetic field is likely to flip within the next 100 years. The magnetic reversal may cause particle storms, cosmic rays. And, even more powerful particles from deep space can be emitted from magnetic reversal.
5. Asteroid Impact
A cosmic interloper piercing Earth’s atmosphere and hitting its surface is more like a familiar Hollywood plot than a possibility. But, scientists do not negate the possibility of an asteroid impacting Earth and wiping out the entire civilization.
How Asteroids Could Destroy Earth
Once every 600,000 years, that type of impact tends to occur. Now we are 40,000 years behind from suffering a massive blow. In 1908, a 200-foot-wide comet fragment penetrated Earth and slammed into the Tunguska region of Siberia. The energy it carried was equivalent to nearly 1,000 times the energy of the atomic bomb dropped on Hiroshima.
6. Gamma-Ray Burst
How are powerful gamma-ray bursts? Scientists theorized that they are as much as 10,000,000,000,000,000 (10 quadrillions) times as powerful as the sun. Scientists theorized that the bursts most likely result from the merging of two collapsed stars.
How Gamma-Ray Burst Could Destroy Earth
Astrophysicists learned that the gamma-ray bursts originate in distant galaxies. The bursts would be too disastrous to comprehend. The bursts would be so bright that they would appear as the sun even at a distance of 1,000 light years. The resultant radiation will fry the atmosphere, forming nitrogen oxides that could cook the ozone layer.
7. Rogue Black Hole
The gravity of the black hole is so powerful that it could swallow everything, even the light that could host their presence. Our galaxy is rife with black holes.
How a Rogue Black Hole Could Destroy Earth
One of them could come closer to earth and swallow everything in its way. Scientists from Durham University theorized the fear of the previously unidentified massive black holes coming in proximity to earth. The black holes do not need to come close to earth. As passing by it could allow a black hole to devour earth into deep space.
8. Solar Flares
Solar flares are also known as coronal mass elections. They are huge magnetic outbursts emanated from the sun.
How Solar Flares Could Destroy Earth
They could bombard earth with torrential high-speed subatomic particles. Ordinary flares are too weak to pierce Earth’s atmosphere and magnetic field. A flare can be enough superpower to cook earth’s atmosphere and fry the ozone layer.
9. Vacuum Metastability Event
The event is what happens when the energy levels of a universe’s vacuum go violent. The resultant collapse from such fluctuating energy levels could obliterate Earth with a light-speed blast. You wouldn’t have the time to blink. The ensuing collapse would screw up the laws of physics as well.
A supervolcano eruption in Siberia occurred about 252 million years ago. And, the eruption wiped out 95% of life on earth. Scientists predicted that the next massive blast will occur in America’s Yellowstone National Park.
11. Alien Life
The universe is vast! Within billions of galaxies and billions of planets, intelligent beings superior to human beings possibly exist. Famed physicist, Stephen Hawkin, is part of a program that is investigating for alien life. Cosmologists and physicists doubt the alien life would come in peace. The alien life could lead an army that could obliterate the human life or cause an imbalance in existing life on earth.
12. Artificial Intelligence
Watched the Terminator movie series? They are still science fiction fantasy movies. Robots acting on their own aren’t far from bein the reality. The United Nations have asked for a ban on killer robots as many organizations were developing them. Stephen Hawkin remarked that the development of artificial intelligence could bring about the end of the human race.
Scientists have found that there are 12 things likely to destroy our world. A group of scientists claims to offer a science-based list of global risks that could wipe out the entire planet. These 12 things involve situations that bring out the ultimate extinction of mankind. Such situations will impact Earth greatly and commence the demise of civilization.
However, scientists are optimistic that humans will live longer than dinosaurs did. They haven’t said we are likely to go extinct because dinosaurs had survived 350 million years though.
