title: Listening Beyond Four Dimensions: Higher‑Dimensional Blast — vNOW Status Snapshot & Tool‑Kit

description: NEXTLEVEL higher‑D blast vNOW (status + tools) – This Zenodo record collects the current status of a falsifiable higher‑dimensional “blast” scenario for the origin of our observable Universe. In this picture, a short and violent episode in a higher‑D phase seeds a cosmological stochastic gravitational‑wave background (SGWB) with a smooth broken power‑law (SBPL) spectrum whose knee lies in the nanohertz pulsar‑timing array (PTA) band. The accompanying files provide:

(i) a machine‑readable grand‑status JSON with all gate values (PTA knee cross‑coherence PCI, ΔN_eff, LVK SGWB safety, black‑hole ringdown ε, lepton and neutrino textures, Blast‑Consistency Index);

(ii) a human‑readable README and scoreboard image explaining how these gates map onto Kaku’s three criteria (GR intact, particle zoo, no anomalies);

(iii) a ΔN_eff / Ω_gw auditor for arbitrary SBPL parameters;

(iv) CSV templates and a run‑card for recomputing the PTA PCI and ringdown gates from raw data; and

(v) origin‑kit notes summarising how a higher‑D “blast” could map into the SBPL parameters.

In the current vNOW configuration, the SBPL spectrum is fully consistent with the common‑signal GW background seen by international PTAs, with ΔN_eff safely below current Planck and forecast CMB‑S4 limits, and with existing LVK stochastic and ringdown constraints. The electron mass is reproduced exactly via a simple higher‑D‑inspired texture, and an exploratory neutrino texture ties the lepton sector to the same small parameter \varepsilon_\ell=\sqrt{m_\mu/m_\tau} while remaining compatible with modern global‑fit values. This release is intended as a reproducible status snapshot and tool‑kit, not as a proof that the Universe must have originated from a higher‑D blast; future data and model refinements can falsify or favour this scenario.
description: We extend the NEXTLEVEL higher‑dimensional blast scenario by (i) fixing an SBPL stochastic gravitational‑wave background with a PTA‑band knee and \Delta N_\mathrm{eff} \ll 10^{-3}, consistent with PTA, CMB, LVK and JWST constraints; and (ii) linking lepton flavour to a single small parameter \varepsilon_\ell = \sqrt{m_\mu/m_\tau} that exactly reproduces the electron mass and predicts all three neutrino mixing angles and the mass‑squared ratio \Delta m^2_{21}/\Delta m^2_{31} within current global‑fit errors. The resulting configuration satisfies a multi‑probe Blast Consistency Index (BCI ≈ 33) and passes Kaku’s criteria #1 and #3, with criterion #2 partially satisfied via a unified lepton sector.
description: How to use this kit.

– Use NEXTLEVEL_GrandStatus_ShortStatus_vNOW.json and README_NEXTLEVEL_GrandStatus_vNOW.md to understand the current gate values (PTA PCI, ΔN_eff, LVK / ringdown safety, electron and neutrino textures, BCI).

– To recompute ΔN_eff and \Omega_\mathrm{gw}(f) for a new SBPL spectrum, edit DeltaNeff_Audit_TEMPLATE_NEXTLEVEL_DBLAST.json and run DeltaNeff_Audit_RUN_THIS_SNIPPET_NEXTLEVEL_DBLAST.py. The example output DeltaNeff_Audit_OUTPUT_NEXTLEVEL_DBLAST_vNOW.json shows the numeric results for the vNOW SAFE2 model.

– To perform an independent PTA knee‑coherence test, fill KneeCSV_COMMON_PRIOR_TEMPLATE_NEXTLEVEL.csv with common‑prior knee posterior samples for each PTA (NG15, EPTA, PPTA) and follow the steps in Preregister_Wedge_RUN_CARD_NEXTLEVEL.txt to compute the PCI metric.

– To tighten the ringdown gate, populate ringdown_with_errors_TEMPLATE_NEXTLEVEL.csv with pooled ε measurements from multiple LVK ringdown events and re‑run the pooling analysis as described in the run‑card.

– To explore lepton‑sector predictions, inspect NEXTLEVEL_neutrino_texture_epsilonl_v1.json, which encodes the ε_ℓ‑based neutrino texture and its PDG‑style pulls.
description: In more basic terms

This record is a status snapshot of a bold but testable idea about the Big Bang. Instead of assuming the Universe simply “started hot and dense”, we explore whether a short, violent event in a higher‑dimensional space could have kicked off our 4‑dimensional Universe and left behind a faint background of gravitational waves.

Pulsar timing arrays (PTAs) – huge “galaxy‑sized” detectors built from many ultra‑stable pulsars – have now seen strong evidence for a low‑frequency gravitational‑wave background with the pattern predicted by Einstein’s general relativity.  This record does not claim to have proved that this background comes from a higher‑D blast. Instead, it packages a set of numbers, scripts and templates that make it easy for anyone to check how well one specific higher‑D inspired model fits current data.

In this model, the blast leaves a smooth broken‑power‑law spectrum of gravitational waves with a “knee” in the PTA band. The files here show that:

– this spectrum can match the PTA signal while staying safely below cosmological limits on extra radiation (ΔN_eff), 

– it is far below current LIGO/Virgo/KAGRA bounds at tens of hertz 

– and it is compatible with black‑hole ringdown tests of general relativity.

On the particle‑physics side, the same framework includes a simple texture that exactly reproduces the electron mass and ties all three neutrino mixing angles, plus the ratio of neutrino mass differences, to a single small parameter shared with the electron sector. These predictions are consistent with current global‑fit values within quoted errors, but can be falsified by future neutrino measurements.

One‑sentence view: this is a reproducible “tool‑kit + scoreboard” for testing whether a higher‑dimensional blast could be a viable origin for the Universe, not a proof that it was.
description: Press & Public Summary

What’s new?

This release wraps up a concrete, testable version of a higher‑dimensional “blast” origin for the Universe and checks it against several independent data sets: pulsar‑timing gravitational‑wave detections, cosmological limits on extra radiation, ground‑based gravitational‑wave bounds and black‑hole ringdown tests of general relativity. It also links this cosmological picture to a simple flavour pattern that fixes the electron mass and predicts key neutrino properties.

Breakthrough claim (carefully stated)

We do not claim proof that the Big Bang came from a higher‑D blast. The breakthrough here is methodological: a fully specified model plus an open tool‑kit that **show that** this scenario is compatible with current PTA, CMB/BBN, LVK and neutrino data, and precise enough that future experiments can clearly confirm or rule it out. PTAs have now reported strong evidence for a nanohertz gravitational‑wave background with the expected Hellings–Downs correlations,  and this model is tuned to live inside that signal while remaining invisible to current CMB and ground‑based detectors. 

Why it matters (if later confirmed)

If later, more precise PTA data, cosmological probes and neutrino experiments keep landing inside the narrow “safe wedge” described here, it would suggest that:

– a specific higher‑D event in the early Universe seeded the gravitational‑wave background we see today;

– this event respected Einstein’s 4D gravity at late times;

– and some of the strange patterns in lepton masses and mixings might be relics of that same higher‑D physics.

That would be a major conceptual shift in how we think about the Big Bang and flavour physics, even though many alternative models would still need to be tested.

60‑second explainer

 





Pulsar timing arrays (NANOGrav, EPTA+InPTA, PPTA) now see a common low‑frequency gravitational‑wave background with the spatial pattern predicted by general relativity. 




This record explores one specific explanation: a short, energetic event in a higher‑dimensional phase that dumps energy into gravitational waves, leaving a smooth broken‑power‑law spectrum with a “knee” in the PTA band.




The provided JSON status files show that this spectrum fits the PTA signal, adds essentially no extra radiation to the early Universe (ΔN_eff ≪ current and forecast limits), and is safely below current LIGO‑Virgo‑KAGRA constraints. 




A separate “texture” connects this cosmological blast to the lepton sector by using one small parameter to reproduce the electron mass and to predict all three neutrino mixing angles and the ratio of neutrino mass splittings, consistent with current global fits.




Everything is packaged as an open, machine‑readable tool‑kit so that other groups can plug in new PTA data, CMB/BBN limits, LVK/LISA results or updated neutrino fits and immediately see whether the higher‑D blast picture survives. 



One‑sentence takeaway

This record does not prove that the Universe came from a higher‑dimensional blast, but it delivers a concrete, data‑driven framework that shows such a blast can pass today’s multi‑probe tests and sets the stage for future observations to decisively confirm or rule it out.
