The discussion centers on the concept of a "temporal bulge" in a two-dimensional, asymptotically flat space, where geodesics are affected by a distortion resembling a half-sphere. Participants debate the implications of such a bulge on the nature of geodesics and the definition of distance in general relativity (GR). Key points include the necessity of specifying a metric for meaningful discourse and the relevance of stress-energy tensors in relation to the Einstein Field Equations (EFE). The conversation highlights the need for mathematical rigor in discussing theoretical models of spacetime.
PREREQUISITESThe discussion is beneficial for theoretical physicists, mathematicians specializing in geometry, and students of general relativity seeking to deepen their understanding of spacetime models and their mathematical foundations.

In other words, you don't currently have a published metric describing what you're talking about. In that case we have no valid basis for discussion.pahenning said:Just wait for the publication before denigrating it...
