The discussion revolves around the transition of geodesics in general relativity (GR) from a mass-free space represented by square or cubic cells to a geodesic system around a mass, typically depicted as circular curves. Participants explore the implications of introducing mass into a previously empty space and the associated challenges in modeling this transition within the framework of GR.
Participants generally disagree on the feasibility of transitioning from a mass-free to a mass-influenced geodesic system. Multiple competing views remain regarding the implications of energy and mass in GR, and the discussion remains unresolved.
Participants highlight limitations in understanding the transition between different geodesic systems, particularly regarding the assumptions about mass creation and the conservation of energy in GR. There are also references to the challenges of interpreting graphical representations of these concepts.
Ok, I just thought that would have been one possible reason for believing that a linear geodesic could turn into a circular one.DaTario said:Yes, Dale, I am aware of this fact. It is like the extended parabola I presented in #25 (not the 2D one).
Thank you, Dale. This comment of yours was enlightening. So, it seems that we can say that there are no circular geodesics, at least as long as no time travel is considered.Dale said:Ok, I just thought that would have been one possible reason for believing that a linear geodesic could turn into a circular one.
