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 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…

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…
