The discussion centers on the behavior of clocks in hyperbolic or negative space-time manifolds, questioning whether they run faster from an external perspective. The term "external perspective" is ambiguous and requires clarification regarding what it is external to. The comparison of clock rates inherently depends on the reference clock and its trajectory through spacetime. Additionally, the definition of simultaneity plays a crucial role in determining clock readings at a given moment. Overall, the relationship between clock rates in such manifolds is complex and context-dependent.

From an external perspective does a clock run faster in a hyperbolic, or negative, space-time manifold?

You will get better and more helpful answers if you can state your question more completely.

It's not clear what "external perspective" could mean in this context. "External" to what?

As with all "does a clock run faster/slower?" questions, there is an implied "as compared with this other clock" and the answer will vary according to the path of that other clock through spacetime and what convention we use to define "at the same time" in statements of the form "At the same time that clock A read ##T_A## clock B reads ##T_B##"

Moderator's note: Spin-off from another thread due to topic change. In the second link referenced, there is a claim about a physical interpretation of frame field. Consider a family of observers whose worldlines fill a region of spacetime. Each of them carries a clock and a set of mutually orthogonal rulers. Each observer points in the (timelike) direction defined by its worldline's tangent at any given event along it. What about the rulers each of them carries ? My interpretation: each...
