The penultimate show of the "Game of Thrones" series really emphasized that a dragon is a weapon of mass destruction, and they showed how basically one dragon could "nuke" a whole city with its fire breath.
Dragons in fact are a major symbol in conspiracy and mythology and can represent evil, power, secret alien lizard rulers and nuclear weapons. This was a big thing
Anonymous Physicist (AP) would talk about.
AP also talked about the quarantine of the planet that keeps the evil PTB aliens here. I don't know how real it is, but that hypothesis does have some explanatory power.
The scary part of the quarantine hypothesis is that the evil aliens will stage some sort of quarantine breakout event, where they use nukes to break a hole in the quarantine barrier and escape through that. In the process, a lot of humans would die.
"The Simpsons" movie back in 2007, actually seemed to be an allegory for the quarantine that AP hypothesized.
The ending of "Game of Thrones" series seemed to actually show a quarantine "breakout":
1) the dragons are the trapped alien evil PTB
2) Daenarys Targaryon and the other rulers of Westeros were the quarantiners keeping the dragons in check
3) As noted above, in the penultimate show, after Daenarys Targaryon lost control, the dragon nuked a city full of humans, the start of the breakout attempt
4) The killing of Daenarys Targaryon by Jon Snow led to the escape of the dragon.
It's not a perfect analogy, but it's interesting to think about how much the writers of "Game of Thrones" knew about
AP's "Ultimate Truths". Certainly the Simpsons writers seemed to have a good understanding of them...
