Abstract

Detection of gravitational waves by LIGO-Virgo observatories disclosed the agent of gravity (gravitons) and together with information paradox of black hole event horizon points to paradigm shift from non-quantum geometry to quantum gravity physics. Historical, philosophical, mathematical, physical and astronomical arguments are presented for demonstration that in the beginning of the 21st century we are on the verge of the forthcoming change in understanding of gravity nature, which will bring new ideas in performing gravitational experiments and interpretation of astrophysical phenomena.
