According to the experts, an asteroid traveling en-route to Earth, is most likely to land in the sea. Why – well, that’s easy to answer. Because the vast majority of our planet is made up of water. A group of experts at the Los Alamos National Laboratory have created a computer model that analyzes what happens when an asteroid “lands” in the ocean. Their video demonstrating their research won the Best Scientific Visualization & Data Analytics Showcase award at Supercomputing 2016. Just take a look at the article and find out more about this.
The experts used a high-end computer models to see how exactly these shockwaves behave and how they change when you tinker around with differing space rock sizes, trajectories, or whether it exploded in an airburst. And, they estimate that an asteroid hitting the ocean within 10 to 20 kilometers (6.2 to 12.4 miles) of a populated coastline could be pretty bad news, inducing hurricane-force air shockwaves and a rush of water resulting in a tsunami-like wave.
This is very important for you to remember – even if you don’t live anywhere near the coast, you could still be pretty screwed. It’s predicted that a 250-meter (820 feet) asteroid could vaporize 250 metric megatons of water. Thrusting all that water vapor into the stratosphere could also affect the world’s climate, as water vapor is a greenhouse gas.
And ladies and gentlemen, this is the main reason why the American Geophysical Union fall meeting announced this week that humanity is not ready for an asteroid strike. Thank you for reading and don’t forget to share.
