SUMMARY
The discussion centers on the validity of Newtonian gravity in light of Einstein's General Relativity (GR). Participants argue that while Newton's theory is fundamentally flawed, it remains useful for practical applications in weak gravitational fields. They emphasize that GR does not invalidate Newton's gravity but rather serves as a more comprehensive framework. The conversation also highlights the ongoing mystery of how mass generates gravity, with physicists admitting a lack of understanding in this area, prompting calls for deeper exploration into fundamental questions of physics.
