Scientists Explain What Would Actually Happen During A Zombie Invasion


When the zombie apocalypse hits, you best be prepared.

Thanks to Cornell University scientists Alex Alemi, Matthew Bierbaum, Christopher Myers and James Sethna, you'll know exactly what to do when the first one bites.

Inspired by "World War Z," the scientists embarked on a research project to determine, with accuracy, how a zombie invasion would affect the United States.

Using SIR (susceptible, infected and resistant), a model used by virologists to determine how quickly a given disease will spread, the team developed a zombie simulator, which breaks down exactly how fast a zombie takeover would dominate the country.

The scientists, using data from movies including “Shaun of the Dead,” first had to determine the variables that would influence the zombies' progress.

Once they pinpointed these variables (zombie speed, human kill rate and bite occurrence), they created simulations that show how fast zombies would dominate the country.

It sounds ridiculous, but their method is both scientifically sound and, in a way, helpful in the study of newly identified diseases.

Alemi said,

The team determined that the safest locations to ride out a zombie invasion would be rural areas, such as the northern Rockies, as fewer people to bite means fewer zombies.

You can play with the zombie simulator yourself to determine how different scenarios would affect the undead's progression throughout the country.

Change the variables (bite-to-kill ratio and speed), click an area on the map and watch as one zombie (represented in red) blossoms into thousands -- and eventually, millions.

The tool is, of course, goofy, but provides an interesting, real-life look into how infectious disease really does spread.
