We all know zombies are in horror movies. Or do we? An article in a University of Leicester physics predicts that zombies could kill people on Earth in just 100 . Students predicted there would only be 273 of a zombie apocalypse. The students were using real zombies. Instead, they pretended a virus had infected someone and spread around the world. One with the virus would have a 90 per cent chance of giving it to another person every . At that , the human population would fall to just 273 people by day 100.
A professor at the university explained why students did using zombies, even though they do not exist. He said: "Every we ask students to write papers for the 'Journal of Physics Special Topics'. It lets the students show off their side and apply some of the physics they know." He also said it gives students practice in and checking papers. He added that it tested the of students to use their understanding of to imaginary situations. This could help in the to prepare us for real-life .
