***SPOILER ALERT: This contains crucial plot points from Game of Thrones Season 7***
The seventh season of Game of Thrones left us wondering how Westeros could possibly survive the upcoming finale in 2019. The Night King, riding one of Daenery's dragons (who he earlier killed and turned into an undead servant of evil), shot fire at The Wall, which is mostly ice and stone, until it finally collapsed and allowed his army of the dead to march into Westeros. While many people had guessed the season would end this way, it didn't stop fans from questioning the physics of how a dragon, shooting fire at the middle of a wall of ice, would be able to topple a massive structure that had stood for centuries.
But he also had some problems that you might have missed.
It’s funny because people really accepted the green fire [of wildfire], which burned down the Sept [of Baelor] and the sea battle in the earlier season. I think that fire can have many different manifestations. I think that the ice dragon fire is clearly still fire because it does melt the Wall and tear it down, but it had a particular quality because it’s coming from an undead dragon. So what the chemical nature of that is and the chemical nature of fire would actually be different coming from a non-sentient being...But obviously, an ice dragon is going to have an icy kind of fire but it’s still fire.
Maybe that's why it so easily obliterated the wall. 🤔— Mark Harrison (@harrisonmj86) September 24, 2017
