WORKING HYPOTHESIS • PUBLIC TEST RECORD • NO DETECTION CLAIM
THE CLAIM • THE TRACE • THE TEST • THE STOP RULE
What if the Big Bang was the aftermath—not the beginning?
HDBLAST asks whether a brief event beyond our familiar four dimensions could have helped ignite our observable universe—and whether its trace could still be tested. The proposal earns attention only by remaining specific enough to fail.
THE HYPOTHESIS IN FOUR MOVEMENTS
From an origin question to a test the universe can grade.
01 • THE ORIGIN QUESTION
Could our beginning be local?
Our hot, dense early universe may have been the local aftermath of a short-lived higher-dimensional energy release rather than the absolute beginning of everything.
02 • THE POSSIBLE TRACE
Listen for a spectral shape.
A one-off event might leave structure in a stochastic gravitational-wave background, including a knee or turnover that can be searched for in pulsar-timing data.
03 • THE CROSS-CHECKS
One suggestive window is not enough.
Any candidate must remain compatible with early-universe limits, laboratory curvature bounds, cross-band behavior, and general-relativistic strong-field tests.
04 • THE STOP RULE
Failure must stay visible.
Missing source support, failed numerical convergence, incompatible authoritative data, or broken cross-probe consistency must constrain or end the affected branch.
CURRENT PUBLIC CHECKPOINT • JULY 14, 2026
The latest release corrects what did not survive audit.
The v20 Fourier-support review withdrew an earlier Fourier-resolved radiative certification and demoted the previously quoted 1.33765% value to an imposed-window profile diagnostic. A narrower selected-shell kinematic channel remains, but it is not an emitted-energy result.
The numerical-readiness stack records A01–A09 as passed and A10–A12 as failed or unmet, so promotion stops. No absolute radiated energy, present-day stochastic background, or detection is established.
This is what a living hypothesis should do: preserve what survives, correct what does not, and stop where the evidence stops.
HOW THE PROPOSAL CAN FAIL
Four gates stand between an idea and a conclusion.
Source gate
The proposed event must possess genuine Fourier support for the radiation channel being claimed. A convenient profile or off-support wave vector cannot substitute for the event’s actual stress.
Numerical gate
Constraint and common-core observables must converge across refinement and domain tests before production initial data or physical higher-dimensional evolution can be promoted.
Authoritative-data gate
Collaboration-grade posteriors and an explicit observable definition—not stand-ins, demos, or reconstructed placeholders—must carry any empirical test.
Cross-probe gate
PTA, early-universe, laboratory, LISA-band, and ringdown constraints must remain mutually consistent without moving definitions after the result is known.
SELECTED PUBLIC MILESTONES
A record of refinement, missing inputs, and correction.
- February 27, 2026 — fingerprint protocol. A Bessel-K shape and knee-scaling test suite was published as a pre-peer-review hypothesis protocol. Open the record.
- April 10, 2026 — authoritativeness closure. Repeated Top-5 files in the reviewed archive were identified as non-authoritative stand-ins. Open the record.
- April 24, 2026 — proof-lane firewall. Proof readiness remained zero while the required authoritative inputs were absent. Open the record.
- May 20, 2026 — negative safety result. An internal operator screen recorded a Sigma-VEV descent wall and explicitly made no proof upgrade. Open the record.
- July 14, 2026 — correction and fail-closed checkpoint. Fourier support was corrected and numerical promotion stopped at unmet gates. Open the current record.
THE CLAIM BOUNDARY
What neither the book nor the current record claims.
- No higher-dimensional blast has been detected.
- No finished microscopic origin mechanism has been established.
- No absolute zero-mode or Kaluza–Klein radiation energy has been established.
- No present-day stochastic gravitational-wave spectrum has been established.
- Related unification, black-hole, dark-sector, faster-than-light, baryogenesis, and Evolution/TMD programs do not validate HDBLAST and are not part of the book’s evidence-bounded claim.
- A public Zenodo deposit provides provenance and reproducibility materials; it is not peer review, independent replication, or a scientific verdict.
