Dec 13, 2020 at 12:45 | comment | added | PM 2Ring | @shashankaMg Bear in mind that there isn't a unique universal now. Even without spacetime curvature, different frames have time axes pointing in different spacetime directions, so they disagree on which events are simultaneous. Curvature makes it more complicated. | |
Dec 13, 2020 at 12:14 | comment | added | user282467 | If I think of 3-manifold evolving In time yes it makes sense. Thank you 🙂 | |
Dec 13, 2020 at 12:06 | comment | added | Eletie | In a way, yes. The full spacetime manifold can be static, but it can still be seen as an evolution for the spatial 3-manifold in the time direction. Does this answer any of your original question? | |
Dec 13, 2020 at 11:28 | comment | added | user282467 | are you saying there is an evolution of 3D space over time ( from t1 to t2 ) and the word static only applies to manifold as a whole ? | |
