SUMMARY

The current scientific theory explaining the origins of gravity is General Relativity (GR), which posits that gravity is a geometric property of spacetime. In this framework, spacetime dictates the movement of objects, while objects influence the curvature of spacetime. There remains a significant gap between General Relativity and Quantum Mechanics (QM), prompting ongoing research aimed at developing a unified theory of Quantum Gravity.

PREREQUISITES
  • Understanding of General Relativity (GR)
  • Familiarity with Quantum Mechanics (QM)
  • Basic knowledge of spacetime concepts
  • Awareness of current research in theoretical physics
NEXT STEPS
  • Research the principles of General Relativity and its implications on gravity
  • Explore Quantum Mechanics and its foundational theories
  • Investigate current approaches to Quantum Gravity, including string theory
  • Review recent publications on the unification of GR and QM
USEFUL FOR

This discussion is beneficial for physicists, students of theoretical physics, and anyone interested in the fundamental nature of gravity and the ongoing efforts to reconcile General Relativity with Quantum Mechanics.

So I know that we can not explain why objects with mass attract other objects with mass but what is the current theory,I mean how science explains it?

Welcome to PF!

The best theory to date is General Relativity (GR). It describes gravity as a geometric property of spacetime where spacetime tells objects how to move and objects tell spacetime how to curve.

However, there is a gap in understanding between GR and Quantum Mechanics (QM) that is an active research area. Many physicists are trying to unify the two into a more comprehensive Quantum Gravity theory.
