Zombie apocalypse would wipe out almost all humanity in just 100 days

A zombie apocalypse could leave humanity on the brink of extinction in just 100 days, research has suggested.

Physics student Chris Davies created a formula to model how zombies could take over the planet in just over three months.

Assuming that a zombie can find one person each day, with a 90% chance of infecting victims with the infection, the University of Leicester student said there would be 273 survivors 100 days after a zombie attack.

Mr Davies, 21, said: "I was interested in films like World War Z and TV shows like The Walking Dead and how the zombie apocalypse spread.

"I thought it would be interesting to see how the numbers come out and if the TV shows portray the spread at an accurate rate mathematically.

"There's not much activity for the first 20 days, but then there's a sharp spike and then there's not many people left at day 100."

Mr Davies - who found the dramatisation of zombie attacks to be largely accurate - said: "As of day 100, I'd prefer to be on the zombie side, you would be quite scared if you were one of the remaining survivors."

And his tips for survival? "Get as far away as you can, as quickly as you can. Geographical barriers are probably your best bet."

The paper did not take into account natural birth and death rates given the figures would be negligible over the course of 100 days.

In a further study, students discovered human survival was more feasible when including the rate of zombies being killed and humans becoming more used to the risks within their model.

Dr Mervyn Roy, a lecturer in the University of Leicester's Department of Physics and Astronomy, said: "Every year we ask students to write short papers for the Journal of Physics Special Topics.

"It lets the students show off their creative side and apply some of the physics they know to the weird, the wonderful, or the everyday."
