Neil deGrasse Tyson Breaks Down the Science Behind ‘Game of Thrones’’s Ice Dragon
Is Viserion breathing fire or ice?

Though the season 7 finale of HBO‘s hit series Game of Thrones has long passed, may fans are still sitting around analyzing every single detail of the previous seasons taking guesses at who will live, who will die, and who will eventually end up on the Iron Throne. Jumping in on the fun is astrophysicist Neil deGrasse Tyson, however looking more in-depth into how the science of the show works, specifically the undead Ice Dragon.
Taking to his personal Twitter account, Tyson breaks down everything from the dragon’s massive wingspans, limb movements and debunked how the White Walkers used chains to drag Viserion out of the lake. The most mind-blowing dragon specifics Tyson had to share comes way of Viserion’s show-stopping blue flame. In George R.R. Martin’s companion book A World of Ice and Fire, Martin wrote, “Whereas common dragons (if any dragon can truly be said to be common) breathe flame, ice dragons supposedly breathe cold, a chill so terrible that it can freeze a man solid in half a heartbeat.” So the main question remains: is Viserion breathing fire or ice? Take a look at Tyson’s knowledge below.
