I think it's weird, but not that far scetched... copying my comment:

They use it as an analogy with a supernova:

> And now this massive star is about to blow.

> (...) it runs out of the fuel that keeps the monster from collapsing in on itself under its own insanely powerful gravity.

> An imploding star crushes itself into a tiny ball, and the rebound instantly triggers a colossal explosion that lights up the entire galaxy. A bursting AI bubble threatens the entire American economy.

> The gravity inside the bubble is investor expectations.

> In a physics thought experiment, all it takes is tossing a pinch of iron into the furnace of a massive star teetering on the edge of explosion to trigger an instant implosion.

The last one isn't even wrong, since iron is the last element a star can fuse (iron core collapse)
