Distinguishable Consequence of Classical Gravity on Quantum Matter.

Area of Science:

• Quantum physics
• Classical mechanics
• Gravitational theory

Background:

• The unification of quantum mechanics and general relativity remains a major challenge in theoretical physics.
• Investigating the quantum nature of gravity is crucial for a complete understanding of the universe.

Purpose of the Study:

• To explore the implications of a classical theory of gravity coexisting with quantum matter.
• To propose experimental tests distinguishing classical gravity from quantum gravity.

Main Methods:

• Utilizing a consistent theory of quantum-classical dynamics in the Newtonian limit.
• Analyzing irreducible fluctuations in classical gravity.
• Proposing experiments with coherent source masses and cross-correlation measurements.

Main Results:

• Classical gravity, if true, necessitates irreducible fluctuations that mediate classical correlations, not quantum entanglement.
• Characteristic phase responses can distinguish classical gravity from quantum gravity and decoherence.

Conclusions:

• Experimental verification of classical gravity is achievable through precise measurements of gravitational interactions between coherent masses.
• The proposed experiments offer a viable pathway to test fundamental hypotheses about the nature of gravity.
