Angular Momentum (rotation) Two black holes with identical properties. Is there any Possible difference?

What if General Relativity and Quantum Mechanics are Independent of Each Other The Physicist Who's Challenging the Quantum Orthodoxy https://www.quantamagazine.org/the-physicist-who-bets-that-gravity-cant-be-quantized-20230710 Jonathan_Oppenheim.mp4 (7 min) Quantum Gravity May Be Far Less Quantum Than Physicists Expected https://scitechdaily.com/quantum-gravity-may-be-far-less-quantum-than-physicists-expected/ A new theoretical framework suggests that some apparent signs of “quantum gravity” may be explained by quantum particles moving through ordinary spacetime. This challenges the assumption that uniting quantum mechanics with gravity requires spacetime to behave quantum mechanically. The framework helps identify which experimental signatures would genuinely require a quantum description of gravity and which ones could arise from more familiar physics. Quote - From one perspective, gravity and spacetime appear to occupy a quantum superposition. From another, gravity remains classical while each particle’s movement is assigned the appropriate quantum state. Although the mathematical descriptions differ, they can lead to the same observable result. That does not establish that gravity is classical, and it does not argue against quantum gravity. Instead, it exposes a problem of interpretation. An experiment may produce a result consistent with quantum gravity without showing that a quantum description of gravity is the only possible explanation. “Our work does not tell us that such experiments rule out quantum gravity,” says Magdalena Zych of Stockholm University and a co-author on the paper. “Rather, it helps us identify which experimental signatures would genuinely require a quantum description of gravity and which ones could arise from more familiar physics. That distinction is crucial for designing future experiments.” - End Quote
