I Curved spacetime bulging in time direction

Click For Summary
The discussion explores a theoretical model of curved spacetime by introducing a bulge in a two-dimensional, asymptotically flat space, affecting geodesics between points. It proposes a unique scenario where space is distorted into the time direction, suggesting that an observer could perceive the center of this distortion as existing at a later time. Initial calculations indicate that the "distance" between points in this temporal bulge varies based on the travel method, raising questions about the nature of geodesics in this model. Participants emphasize the necessity of specifying a metric to meaningfully discuss the proposed spacetime and its implications. The conversation highlights the importance of mathematical rigor in theoretical physics discussions, particularly regarding curvature and stress-energy tensors.

Concerning the metric: I can let you know when I have it published (which I intend to do).

Just wait for the publication before denigrating it...
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.
