Can I express "stationary spacetime" and "static spacetime" in this way?
Can I express "stationary spacetime" and "static spacetime" in this way?
stationary spacetime: if we arrange a set of observers locating in any places, then each of them should observe nothing change at the place where s/he is located.
static spacetime: if our observers can contact with each other (let us neglect the technical problems of the "contact" amongst them), they may find out that what they observed is the same and same over time.
