How The Planet Might Be Taken Down

#1

At first, it looks like a fireball. It grows bigger and bigger by the minute. Soon, it seems to be larger than the Sun. People are frozen, staring at the mysterious object. They do not know that they should be running for their lives. Not that running would help. The asteroid crashes into the Earth at top speed, breaking through the crust. Thousands of cubic miles of solid rock instantly vaporizes. Everything and everyone close enough to see the crash don’t live longer than a few seconds. The ground around the impact crater is covered with hot ash, grit, and rubble. Grass, trees, and shrubbery burst into flames. And this is just the beginning...

The crash sets off a series of natural disasters. Tsunamis shake the planet. What didn’t burn down in the first few seconds are getting wrecked. In some places, Tsunami waves reach up to a thousand feet. Earthquakes rattle the planet even more. After the asteroid crashed, a blast of wind whisks through Earth. Its speed is more than 1000 km/h. The hurricane flattens down everything that is standing, scattering debris for miles around. Volcanoes erupt all over the world. A bit further away from the impact zone, the sky darkens. This is because of debris falling back onto the Earth. These are just the first hours of the crash, but the planet is already dying.

By the time the sky gets lighter, there’s no life on Earth. Ash from the fire is still in the air. It begins to rain. Ash makes the rain highly acidic. Fires keep raging. They produce tons of toxins that destroy the ozone layer. Sun’s UV rays hit the Earth directly, boiling the planet.

A rogue planet crashes into the Earth. The force knocks Earth out of the habitable area of the Solar System. Earth is unlucky enough to be pushed into an extreme orbit, far away from the Sun. The climate is getting colder and colder. People move to countries near the equator. Quite soon, the planet is covered in a thick sheet of ice. There is a lack of food and other resources. It’s getting darker and darker. Plants and animals are dying. The Earth is still moving further away from the Sun. The Sun’s gravitational pull on our planet weakens. Eventually, Earth gets too far away and transforms into a lifeless piece of rock, merely floating in space.

The Sun has run out of hydrogen. This triggers several reactions. In the end, the core heats up and becomes denser. As a result, the Sun expands. In this transformation, the Sun swallows Mercury, Venus, and Earth. Earth’s orbit changes as it’s pulled toward the Sun. Oceans vaporize. Life is destroyed. In the end, the Earth becomes… molten.

An immensely bright flash occurs in space. It outshines everything around Earth. It is a gamma-ray burst. It is close enough to wipe out Earth’s atmosphere. This carries one quadrillion( 10 000 000 000 000 000) times as much energy as our Sun. When this flash occurs, the radiation is so strong that it cooks the atmosphere. Nitrogen Oxides are created. They destroy the ozone layer. Without this layer, Sun’s UV rays hit Earth directly. They wipe out Plankton in the oceans. These Plankton produce 50% - 70% of the world’s oxygen. Soon, there’s a severe lack of oxygen. Living creatures start to disappear. In the end, the heat and UV light turn the planet into a huge chunk of barren rock.

Never mind, I don't like any of these. But hey, let’s leave the Earth the way it is. Why don’t we just blow up Mars or something?
