nonparallel debunker of picture show and TV Neil deGrasse Tyson take onGame of Throneson Sunday evening , analyzing everything from the chains the army of the dead used to pluck up dead dragon Viserion ( wrong slant ) to the dragons themselves ( good annexe duad , thoughexperts we spoke withsay they ’re still too heavy to fly ) . And then he dropped an intriguing tweet that just might excuse Ice Viserion ’s gloomy fire , which easily cut through the Wall :
Inverse ’s Yasmin Tayagtook a deep diveinto the aperient of dragon fervour after the time of year stopping point and concluded that , according to science , blue flames are the hottest of them all . TypicalGame of Thronesdragon fire — the scarlet , yellow , and orange kind — is the outcome of incomplete burning . The color is make by the fuel in the dragon ’s gut ( likely carbon ) bring out chemicals as gas in a summons known aspyrolysis . Blue flaming , though , think of complete combustion , which , harmonize to Tayag , " can only occur when there ’s plenty of atomic number 8 available to allow a flame to get super hot , and the fuel being bite does n’t release too many extra chemical substance during pyrolysis that might lead to a different coloured flame . "
In August , Game of Thronessound house decorator Paula Fairfield — perhaps in an seek to answer viewers ’ nagging dubiousness about whether Viserion was blowing fire or ice — toldVanity Fair ’s Joanna Robinson that , “ He ’s just go at it and slice up with this . It ’s kind of like liquid N . It ’s so , so cold . So imagine if that ’s what it was , but it ’s so cold it ’s hot . That kind of thing . ”

This could have big consequences if Ice Viserion and Drogon face off . " Ifthe HBO series decides to follow these particular laws of thermal natural philosophy ( and why should it whenThronesso flagrantly disregarded chain physics ? ! ? ) , then Viserion will surely be at an advantage if and when he ever decease talon - to - talon with his brother Drogon,“wroteRobinson in response to deGrasse Tyson ’s tweet .
Game of Thrones ’s concluding season wo n’t debut until late 2018 or 2019 , so we have a farseeing time to wait before we see which flying lizard ’s flak comes out on top .
