This talk examines the foundational properties of gravity through a range of theoretical perspectives, including geometrical, field-theoretical, quantum, and balance-law approaches. These frameworks are systematically compared and analyzed to identify their core assumptions and predictions. Observational evidence from cosmology, astrophysics, gravitational-wave detections, and particle physics experiments is then employed to rigorously test and constrain these properties, providing a unified assessment of gravity across scales.
