Why does the preposition used with **geht es ... um** vary?

Question

A text I am studying has two uses of geht es ... um as follows.

Bei einer Kur geht es um die Gesundheit.

and

Mittlerweile geht es im All um die wissenschaftliche Forschung.

Why is bei the preposition in the first and in the preposition in the second?

Answer 1

The difference is the subject, not the usage of "geht es um". "All" has a spatial component, as it translates to "universe" or "outer space". "Kur" is not a location, thus a causal preposition is used.
