C8 – Methods, Data & Reproducibility

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…

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…

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.…

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 WinFuture article popularizes an optics result whose primary source is Yessenov et al. (arXiv 2025; Optica 2026): a direct observation of a spatially structured Montgomery effect (lensless self-imaging) that generalizes the Talbot effect to aperiodic structures and is claimed to show repeated strongly focused spots (~10 µm) in free space. According to the abstract, a dynamic…

In https://arxiv.org/abs/2510.13124 (Ghalekohneh & Zhao, preprint 2025), a decomposition of non-reciprocal, far-field radiative heat transfer in multi-body emitter networks is described: the heat current is split into an equilibrium contribution with persistent internal circulation and a non-equilibrium contribution for exchange with the environment; the latter is claimed to be engineerable such that “perfect” thermal rectification…

Superconductivity as a Null-Test Regime: Is There an Entropy Residual Beyond the Heat Balance?

In the microscopic theory of superconductivity by Bardeen, Cooper & Schrieffer (1957), an energy gap leads to strongly suppressed dissipative quasiparticle contributions at low temperatures, enabling a very low-loss reference mode of operation. Josephson (1962) predicts, for tunnel junctions, a lossless DC supercurrent up to a critical limit as well as a dissipative voltage state…

In Crespi et al. (Monthly Notices of the Royal Astronomical Society, 2026; arXiv 2025), Sgr A* is modeled as a fermionic dark-matter core plus halo; the authors report that the orbital parameters derived for S2 and five G sources differ from a BH-potential variant by less than one percent. Pelle et al. (MNRAS, 2024) ray-trace such fermion cores…
