is a kind of diagrammatic description in relativity relating the velocity of a body to one spatial dimension and two different time dimensions. It's similar in form, but not the same as the perhaps more familiar Lichtkegel
(two spatial dimensions and one time dimension). Curiously, although Lichtkegel
translates to light cone
in English, I can't find any uses of the phrase time cone
, but perhaps I haven't searched enough. Anyway, although the use of Zeitkegel
in the OP is a bit geschwafelig
, I don't think it's too bad an analogy, or at least it wouldn't have been, had they written Lichtkegel
, since a light cone is about showing the range of possible futures (and pasts) in spacetime and here they're talking about the possible futures in 'moneytime', if you will.
A translation of time cone would keep the geschwafeligkeitsniveau about the same.
