Strange financial physics of the inverse bubble.
John Kay from the FT is asking in commentary if there is a term for the inverse of a "Bubble". He muses that it must be somewhere in physics. The particle physicist in me wants to say the obvious "anti-bubble" like there is matter and anti-matter.
From astrophysics, the notion of white dwarf, the remaining heavy core of exploded star, could work with one caveat. Obviously what is nice about the bubble imagery is that it conveys fragility and the certainty that it will explode. The inverse of a bubble is a price that artificially too low and will re-inflate. It needs a phenomena from physics where something is deflated with the knowledge that it will eventually re-inflate. A white dwarf, will not explode.
Oh, I know, a limp noodle?
I think I would stick to anti-bubble. The reason is that the anti-bubble IS A BUBBLE, a ponzi scheme that will run out of steam as it runs out of numbers and will explode. The bubble is such a thing and losing that imagery is losing the main attraction of the word: the sensation of "time running out, artificial, inflated".
The anti-bubble it is!
