The website allows you to simulate a space rock crashing into the earth

Warning: This website is highly addictive.

A developer has created an interactive map that lets you play God’s hand and potentially end civilization.

Asteroid Launcher users can determine the bomb’s size, speed, and trajectory, then choose a location where they want it to land.

We’ve tried it in multiple places with the slightly twisted goal of seeing who can create the most destruction.

The software determines how densely populated the area is and how many people would be vaporized into the crater or killed by the fireball, decibel shock wave, strong wind blast and earthquake created by the asteroid .

So if you launch a mile-wide asteroid at 100 km/s at 245,000 mph at our office in central London, you will create:

• A 43-mile-wide crater that vaporizes 8.9 million people immediately
• A fireball 90 miles wide that kills 66 million people
• 247 decibel shockwave causing lung damage within 266 miles (and 15.6 million additional deaths)
• 11,000 mph wind kills another 47 million people
• And a magnitude 9.2 earthquake that kills around 500,000 more people

So basically most of the UK, over half of France and the Republic of Ireland, the whole of the Netherlands, Belgium and Luxembourg and a quarter of Germany would have their day wasted.

The website was created by Neal Agarwal, a developer with a passion for creative coding. The project took him about two months to build with the first month spent on research.

“I love playing disaster scenarios in my head, so I always wanted a tool that would help visualize the effects of a major natural disaster,” Agarwal told Motherboard.
