In https://pmc.ncbi.nlm.nih.gov/articles/PMC12315985/ (Wang et al., Science Advances, 2025), it is claimed that a Bell inequality is violated in a four-photon interference setup, even though the photons involved are not described as entangled within the system. The report names quantum indistinguishability via path identity as the mechanism and uses postselection on four-fold coincidences; the Bell parameter…

Where Does the Quantum World End? An Operational FBA View on Nanoparticle Interference (MUSCLE)
•
5 min read
In 2026, a Vienna team demonstrated quantum interference of sodium nanoparticles with more than 7,000 atoms (masses >170,000 Da) in the MUSCLE interferometer—setting a new size record for matter-wave interference. “Where does the quantum world end?” can thus be sharpened experimentally: How large may an object become, and how “classical” may its environment be, before…

In https://www.frame-budget-approach.eu/PDF/DE/FBA_09_Kosmische_Dynamik_Time_Dilation_Inflation_TDI.pdf (PDF/preprint, 2026), “accelerated expansion” is formulated as time-dilation inflation via the factor χ(t) and operationalized as overdetermined through distance data, chronometers, redshift drift, and SN time dilation in null tests N1–N3. In the same part, “before time” is not treated as t<0 physics, but as an operational question about the start of the…

Prime Numbers in Black Holes? Zeta Structures, Primitive Cycles, and a Possible FBA Perspective
•
4 min read
Abstract Recent popular science reports have suggested that “prime number patterns” might appear inside black holes. However, what lies behind this formulation is typically not a direct connection to the Riemann zeta function itself, but a deeper structural mechanism: primitive cycles in dynamical systems naturally generate zeta products whose zeros encode resonances or spectral fluctuations.…

In https://opg.optica.org/optica/fulltext.cfm?id=572911&uri=optica-12-6-843 (Optica, 2025), the largest coordinated campaign to date is reported: 10 optical clocks in 6 countries were compared simultaneously over fiber and satellite links for weeks (including 38 evaluated frequency ratios). The FBA view turns this into a pass/fail program: not “the best clock,” but a preregistered consistency experiment that licenses link and…

In https://arxiv.org/abs/2506.01476 (preprint, 2025), Guo et al. extract an EWS time delay τEWS for quantum transitions via spin- and angle-resolved photoemission and report strongly material-dependent attosecond scales (among others ~150 as in 1T-TiSe2/1T-TiTe2, >200 as in CuTe, 26 as in Cu). The central finding is that the measured timescale covaries with the (effective) symmetry and dimensionality of the electronic structure.…

In a new CMS analysis at the CERN LHC, Z bosons are used as a “tag” in PbPb heavy-ion collisions, and in Z–hadron correlations a soft depletion/wake signature is found on the away-side. If a “cosmic primordial soup” truly responds like a fluid, then exactly such a pattern should show up as a precise, repeatable…

Ekpyrotic Universe from an FBA Perspective: A Good Early-Cosmology Idea, but Only with Hard Channel Separation
•
6 min read
The Spektrum podcast picks up a real primary line: in https://arxiv.org/abs/hep-th/0103239 the hot Big Bang is described as the result of a brane collision in an extra-dimensional setting; the model starts from a cold, nearly static state and claims to address the horizon, flatness, and monopole problems without a standard inflationary phase. At the same…

In the Spektrum podcast on warm inflation (discussed since 1995), the focus is on a new PRL/preprint model (2025) that contrasts the standard assumption of cold inflation (near-vacuum during inflation, reheating afterwards) with a sustained thermal bath throughout the inflationary phase. This shifts the emphasis: not only how fast space expands, but whether particle production/dissipation…

The work by Koch, Riahinia & Rincon (Phys. Rev. D 112, 084056, 2025 / arXiv:2510.00117) introduces “q-desics” as quantum-corrected analogues of geodesics and derives an equation of motion based on expectation values of operators such as the affine connection (not only on ⟨g⟩). In the example of static, spherically symmetric quantum-gravity backgrounds, the authors report…
