SUMMARY
The discussion centers on the ongoing debate regarding the interpretation of gravity in physics, particularly the distinction between Newtonian mechanics and Einstein's General Relativity (GR). Participants argue that while professors often describe gravity as a force of attraction, this perspective is rooted in Newtonian physics, which remains a practical approximation for many everyday scenarios. Critics of this approach emphasize that gravity should be understood as the curvature of spacetime caused by mass, a concept introduced by Einstein. However, the consensus is that both models are valid within their respective contexts, and a comprehensive understanding of gravity requires familiarity with both frameworks.
