Do decoherence, gravity, dark matter and dark energy all originate from quantum corrections?

Phys · · 1093 words · By Kyoung Yeon Kim
Quantum Physics and Cosmology Alternative Theories to Dark Matter/Energy

The article discusses a scientific proposal suggesting that dark matter and dark energy might not be physical substances but rather effective phenomena arising from quantum corrections in gravity. The author details how analyzing the Wigner–Moyal equation in phase space suggests that increasing resolution induces a transition from quantum to classical statistics, which the author then applies to explain galactic rotation curves and cosmic expansion without invoking these dark components.

“Only about 5% of the universe is composed of normal matter that we can directly observe, while the remaining 95% is widely believed to consist of dark matter and dark energy.”
CORROBORATED
Multiple web search results from OpenStax and Physics LibreTexts independently state that visible matter constitutes only about 5% of the universe, with the remaining 95% attributed to dark matter and dark energy. This meets the requirement of multiple independent sources confirming the fact.

“In a recent study published in the International Journal of Modern Physics D, I proposed that dark matter and dark energy may not correspond to physically existing substances, but could instead emerge as effective phenomena arising from the quantum nature of gravity.”
SINGLE SOURCE
The claim suggests that dark matter and dark energy may emerge from quantum gravity effects. While one web search result mentions that 'Decoherence, gravity, dark matter, and dark energy may arise from resolution-dependent quantum corrections in phase-space quantum mechanics,' this is the only source supporting this specific hypothesis, making it a single-source claim.
