It probably isn't who you think. Fans of the series have argued since it began over who the main character of Game of Thrones it - it's tricky as whenever one seems to be taking the lead, they are killed off.

Mathematicians have the answer - they have worked out who the real star of the immensely popular series is by mapping out every character in a highly scientific manner.

Andrew J. Beveridge, an associate professor of mathematics at Macalester College, and Jie Shan, an undergraduate, used network science, a branch of applied graph theory that draws from several disciplines, including economics, sociology, and, computer science, to examine how information flows from one thing to another.

This basically created a map of Game of Thrones influence - and showed who the main character is.

“This is a fanciful application of network science,” Beveridge told Quartz. “But it’s the kind of accessible application that shows what mathematics is all about, which is finding and explaining patterns.”

They even published their study, called Network of Thrones (of course) in the Mathematical Association of America’s publication, Math Horizons.
