Terrifying simulation shows what would happen if asteroid that wiped out dinosaurs hit Earth today

A terrifying simulation has revealed what would happen if the asteroid that wiped out the dinosaurs hit Earth now - and it's about as horrifying as you could imagine.

Around 66 million years ago, an asteroid six miles wide in diameter slammed into the planet, creating a huge crater and triggering tsunamis across the globe.

The devastating impact also created a huge amount of dust and debris, which blocked the Sun for long periods of time.

It's believed the asteroid - called the Chicxulub impactor - wiped out three-quarters of all species living on Earth at the time, including the dinosaurs, which were already thought to be declining in numbers before the cosmic event.

These days, asteroids and their path of travel are tracked by experts, but it doesn't stop people worrying - and speculating - about what could happen if one as big as the Chicxulub impactor decided to crash into the planet.

Over on YouTube, AstroKobi created a video, discussing what would happen if the asteroid that wiped out the dinosaurs ended up hitting Earth today.

Sharing a simulation, the YouTuber explained: "The asteroid would enter our atmosphere, travelling 100 times faster than a commercial airplane, it strikes the surface with more explosive power than 10 billion atomic bombs.

"Anyone in central America or the southern United States would be killed instantly, 100-500 million people gone.

"Anyone within a 1500km radius of the impact zone would be killed by the sound wave alone."

AstroKobi explained that tsunamis would flood coastlines and a large chunk of the population would drown from flooding.

They continued: "The impact would immediately trigger massive earthquakes around the globe, tsunamis would flood virtually all the coastlines on Earth, half of Earth's population would drown due to flooding.

"Within 48 hours, Earth's population would have dropped to around two billion, the only chance of survival would be to hide in underground bunkers.

"New Zealand is widely considered to be the best place on Earth to survive such an event. As a result, wealthy people have been obtaining citizenships to start building their underground bunkers."

In the comments, people were pretty horrified, with one writing: "I’m going to New Zealand now."

While another said: "If this happens new Zealand will be filled with people."

Others pointed out that the asteroid might hit New Zealand, in which case it probably wouldn't be the best place to go.

And a third simply commented: "So basically, we're cooked."
