SUMMARY
The discussion centers on the relationship between spacetime curvature and mass, specifically addressing whether the curvature is influenced by relativistic mass or rest mass. It concludes that the modern consensus is to avoid the concept of relativistic mass, advocating instead for the use of invariant mass and the formula for momentum as γmv. The stress-energy tensor is identified as the source term for gravity in general relativity, emphasizing the importance of clarity in terminology to prevent confusion.
