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

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. The institutional report frames the development in practical terms and ties it to the broader mission or observing effort.

That matters because cosmology operates at the edge of what current instruments can measure, where systematic errors and model assumptions are never trivial. Small discrepancies between independent measurements have historically pointed toward missing physics rather than simple calibration errors, and the ongoing tension in the Hubble constant is a live example of how a persistent disagreement between methods can reshape the theoretical landscape. Each new dataset that approaches this territory with independent systematics adds real information to a problem that has resisted easy resolution for more than a decade.

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.

Moyal in the 1940s, the equation has been widely applied but is known to suffer from severe numerical instability. In a previous study published in the Journal of Computational Electronics, I showed that this instability originates from a peculiar property of higher-order quantum corrections.

These results suggest that resolving phase-space structures beyond the uncertainty principle naturally induces a transition from quantum to classical statistics, implying that. After appropriate normalization, the resulting dynamics reproduce first-order post-Newtonian behavior and agree with weak-field general relativity tests.

When the gravitational potential of the observable universe is taken into account, the resulting background resolution becomes ΔxΔk ∼ 1, coinciding with the quantum correction. Discover the latest in science, tech, and space with over 100, 000 subscribers who rely on Phys. org for daily insights.

The relevance goes beyond one dataset because even small shifts in measured parameters can matter when the field is testing the limits of the standard cosmological model. The Lambda-CDM framework describes the observable universe with remarkable economy, but its success rests on two components, dark matter and dark energy, whose physical nature remains entirely unknown. Any credible measurement that tightens or loosens the constraints on those components moves the entire theoretical enterprise forward, regardless of whether the immediate result looks dramatic on its own terms.

Because the account originates with Phys. org Physics, it functions best as a primary institutional report that is close to the data and operations, not as independent scientific validation. Institutional communications are produced by organizations with legitimate interests in presenting their work in a favorable light, which does not make them unreliable but does make them partial. Details that complicate the narrative, including instrument limitations, unexpected failures and results below projections, tend to be minimized relative to progress messages. Technical documentation and peer-reviewed publications, where they exist, provide the complementary layer that institutional releases cannot substitute.

The next step is to see whether the effect survives when independent surveys, different calibration strategies and tighter control of systematic uncertainties enter the picture. Programmes such as Euclid, DESI and the Rubin Observatory will deliver datasets over the next several years that cover the same parameter space with largely independent methods. If the current signal persists through those tests, its theoretical implications will become impossible to set aside.
