Ultrasound-induced anomalous radioactive decay supports space-time deformation hypothesis

A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed Space-Time (DST) theory. The findings, published by Stefano Bellucci (INFN-Frascati) and Fabio Cardone (ISMN-CNR), suggest that brief ultrasonic exposure can trigger a departure from conventional exponential decay laws, mediated by energy-dependent space-time distortions that violate local Lorentz invariance (LLI).

In a groundbreaking study exploring the frontier between nuclear physics and space-time geometry, Stefano Bellucci and Fabio Cardone report anomalous radioactive decay behavior in the isotope cobalt-57 (Co-57) when exposed to ultrasound at 2.25 MHz. This unexpected deviation from the standard exponential decay curve—specifically in the 14.4 keV Fe-57 emission line—is interpreted through the lens of Deformed Space-Time (DST) theory, which posits that under certain energy conditions, nuclear processes occur in a locally non-Minkowskian metric.

"Only a few nanoseconds of ultrasonic activation—less than one percent of a single wave cycle—are enough to trigger measurable effects consistent with a deformed space-time," explains Bellucci. These effects include enhanced transformation of Co-57 nuclei without traditional radioactive decay emissions, suggesting an alternative, non-weak-interaction-driven nuclear transformation.

At the heart of the study lies the hypothesis that Ridolfi cavities—microcavities formed under ultrasonic stress—act as "nuclear micro-reactors," enabling strong-interaction pathways not accessible under standard conditions. This dual-path decay mechanism, combining traditional weak decay with DST-induced transformation, offers a radical reinterpretation of nuclear stability and decay in dynamic fields.

Notably, the research draws parallels to previous DST-based experiments conducted by the same team involving isotopes like thorium-228 (Th-228) and nickel-63 (Ni-63), where cavitation led to significant reductions in radioactivity. The new findings from the Hagelstein-type experiment with Co-57 serve as an independent confirmation, revealing persistent metric deformation effects (latency) and energy coupling between fields—phenomena consistent with the so-called Mignani mimicry.

“This work challenges the long-held assumption that radioactive decay is immutable under classical field exposure,” says Cardone. “If space-time itself can deform in response to external stress, our understanding of fundamental interactions—and their constraints—must be revisited.”

The authors emphasize that the observed decay anomalies imply a deeper violation of Local Lorentz Invariance, hinting at broader implications for causality and even the constancy of the speed of light. Future experiments are proposed to determine whether the observed transformations result from an increase in decay rate—or a true metamorphosis of nuclear identity, absent radiation emission.

As a forward-looking application, the authors propose real-time radioactivity monitoring during sonication. “If sonication leads to more radiation, it implies faster decay,” notes Bellucci. “If not, we are looking at a fundamentally different reaction altogether.”

This study opens new avenues in nuclear science, cosmology, and the physics of space-time—where matter, energy, and geometry may interact more dynamically than previously imagined.
