Appendix C: Sources and Verification
A section of The Cosmic Recursion by Mayone Maha Rajan.
SOURCES AND VERIFICATION
This is not a bibliography. It is a working list, and it is incomplete in a specific way that I want stated before anyone relies on it.
The entries below identify sources by author, approximate year, and venue where I am confident of them. They do not carry volume numbers, page ranges, or DOIs. Supplying those from memory is precisely the failure this book spends eleven chapters describing — a citation that looks authoritative and cannot be decompressed back to a real object is worse than no citation, because it survives checking by discouraging it.
Every entry here needs completing against the actual paper before publication. Where I am uncertain of a detail I have said so rather than smoothing it.
C.1 Principal sources by chapter
Introduction and Chapter Two — the ledger
- Landauer, R. (1961), IBM Journal of Research and Development — the original derivation of the erasure cost.
- Landauer, R. (1991), Physics Today — the "information is physical" essay.
- Szilárd, L. (1929) — the single-molecule engine.
- Bennett, C. H. (1982), International Journal of Theoretical Physics — the resolution of Maxwell's demon via memory reset.
- Bérut, A., Arakelyan, A., Petrosyan, A., Ciliberto, S., Dillenschneider, R., Lutz, E. (2012), Nature — experimental verification of the Landauer limit in a colloidal double-well trap.
- Norton, J. D. and Earman, J. — the critical literature on whether the information-theoretic exorcism is circular. Several papers across roughly 1998–2013; needs a specific citation chosen.
- Prigogine, I. — dissipative structures; Nobel lecture 1977 is the accessible entry point.
- Schrödinger, E. (1944), What Is Life? — including his own note acknowledging the "negative entropy" criticism.
- Luria, A. R., The Mind of a Mnemonist — the Shereshevsky case study.
- Tononi, G. and Cirelli, C. — synaptic homeostasis hypothesis; multiple papers, a review should be cited rather than the original.
- Ryan, T. J. and Frankland, P. W. (2022), Nature Reviews Neuroscience — forgetting as a form of learning.
- ⚠️ Glymphatic clearance during sleep — Xie et al. (2013), Science, and the more recent work challenging it. Both must be cited; citing only the first is the error the text warns against.
Chapter One — recombination and infantile amnesia
- Planck Collaboration — final cosmological parameter results. Cite the definitive data release.
- COBE/FIRAS — Mather et al. and Smoot et al., early 1990s; the blackbody spectrum and the anisotropy detection.
- Guth, A. (1981); Linde, A. (1982); Albrecht, A. and Steinhardt, P. (1982) — inflation.
- Ijjas, A., Steinhardt, P., Loeb, A. — the falsifiability critique. Scientific American (2017) is the accessible version; a technical citation would be stronger.
- BICEP2 Collaboration (2014) and BICEP2/Keck–Planck joint analysis (2015). Cite both, in that order.
- Akers, K. G. et al. (2014), Science — hippocampal neurogenesis and infantile forgetting.
- ⚠️ The infantile amnesia mechanism literature is contested. A review rather than a single advocate's paper.
Chapter Three — molecular clouds and brown dwarfs
- Jeans, J. (1902) — the instability criterion.
- A modern star-formation review for the turbulence-regulated picture; Mac Low & Klessen or McKee & Ostriker (2007), ARA&A.
- Bodenheimer or equivalent for the deuterium- and hydrogen-burning mass limits.
- Nakajima, T. et al. (1995), Nature — Gliese 229B. Rebolo, R. et al. (1995) — Teide 1.
- Luhman, K. (2014) — WISE 0855−0714.
- Solar system mass fraction (99.86%) — any standard reference; verify the figure.
Chapter Four — the main sequence
- Bahcall, J. — the standard solar model; his work on solar neutrinos is the natural citation.
- Davis, R. — Homestake results across three decades.
- SNO Collaboration (2001, 2002) — neutral-current measurement establishing flavour change.
- Super-Kamiokande (1998) — atmospheric neutrino oscillation.
- ⚠️ Photon random-walk escape time — estimates in the literature range from ~10⁴ to ~10⁶ years. The text says so. Do not let a copy-editor pick one.
- Faint young Sun paradox — Sagan & Mullen (1972) for the original; a recent review for current status.
- Solar core power density (~276 W/m³) — verify against a stellar structure text rather than a popular source.
Chapter Five — nucleosynthesis
- Burbidge, Burbidge, Fowler & Hoyle (1957), Reviews of Modern Physics — B²FH, the founding paper.
- Chandrasekhar, S. (1931) — the mass limit.
- Bethe, H. and Wilson, J. — delayed neutrino mechanism. A modern simulation review is needed for current status.
- LIGO/Virgo and multi-messenger collaborations (2017) — GW170817. The multi-messenger paper has an extraordinary author list; cite it properly.
- Kilonova / r-process yield — cite a specific analysis rather than a press figure. ⚠️ The "several Earth masses of gold" number circulates loosely.
- Zinner, E., Nittler, L., Bernatowicz, T. — presolar grains.
- Heck, P. R. et al. (2020), PNAS — presolar grain cosmic-ray exposure ages.
- Adams, S. M. et al. (2017) — N6946-BH1. ⚠️ And the later infrared reanalysis challenging it. Both required.
- Tedeschi, R. and Calhoun, L. (1996) — the Post-Traumatic Growth Inventory.
- Frazier, P. et al. (2009) — prospective study finding weak correspondence between reported and measured change.
- Bonanno, G. — resilience as the modal trauma outcome.
Chapter Six — pulsars
- Hewish, A., Bell, S. J., Pilkington, J., Scott, P., Collins, R. (1968), Nature — the discovery paper.

- Cromartie, H. T. et al. (2020) — PSR J0740+6620 mass.
- Hessels, J. et al. (2006) — PSR J1748−2446ad, 716 Hz.
- Hellings, R. and Downs, G. (1983) — the angular correlation.
- NANOGrav Collaboration (2023), ApJL — the 15-year dataset. ⚠️ Cite EPTA, PPTA and CPTA alongside it; all four announced together and citing only NANOGrav misrepresents the result.
- Petroff, E. et al. (2015), MNRAS — perytons and the microwave oven.
- CHIME/FRB and STARE2 (2020), Nature — FRB 200428 from SGR 1935+2154.
- Sagan, C. and Drake, F. — the Pioneer plaque; contemporaneous Science paper.
- ⚠️ Pulsar versus atomic clock precision — cite a current optical-clock uncertainty figure. This number improves every few years and the text's comparison must not go stale.

- Steinhauer, J. (2016) — analogue Hawking radiation in a BEC, ⚠️ with the critical responses.
- ⚠️ The trauma-memory literature is genuinely contested. Brewin and Rubin/McNally represent opposing positions and both must be represented, or the paragraph should be cut.
Chapter Eight — dark matter
- Zwicky, F. (1933), Helvetica Physica Acta — Coma Cluster.
- Rubin, V. and Ford, K. (1970 and following) — rotation curves.

- Sawala, T. et al. (2025), Nature Astronomy — the ~50% revision.
- ⚠️ The 2026 reanalysis — preprint at time of writing. Verify publication status; if unpublished, the text must say so.

- Ibata, R., Gilmore, G., Irwin, M. (1994) — the Sagittarius dwarf.

C.2 Verification schedule
Every figure below moves. Each must be re-checked at final proof, and each is a candidate for revision at any subsequent printing.
| Item | Chapter | What to check | Risk if stale | |---|---|---|---| | DESI dark energy significance | Eleven | Current data release; which supernova compilations were combined; whether the evolving-w preference has strengthened or weakened | Highest in the book. The text describes an actively moving result. If it has resolved either way, the paragraph is wrong as written | | Andromeda merger probability | Nine, Introduction | Publication status of the 2026 reanalysis; any further revision | The chapter is built on this being live. If it settles, the argument still works but the framing must change | | Planet Nine | Ten | Rubin/LSST survey status and any detection or exclusion; the author's own forecast window | If found or excluded, Chapter Ten's central case study changes character entirely | | Rubin Observatory operations | Ten | Survey start, first TNO data releases | Text describes it as forthcoming | | Direct detection limits | Eight | Latest LZ / XENONnT exclusions; status of the neutrino fog | Numbers move every 18 months | | Pulsar timing array significance | Six | Whether the nanohertz background has reached 5σ | Text says "evidence, not detection." May no longer be true | | Optical clock precision | Six | Current best fractional uncertainty | Used in a direct comparison with pulsars | | Confirmed exoplanet count | Ten | "Nearly six thousand" | Rises continuously | | Neutron star maximum mass | Six | Any heavier well-measured object than PSR J0740+6620 | Cited as the record | | Proton decay limits | Eleven | Super-K and successors | Lower bound rises | | Presolar grain ages | Five | Status of the exposure-age method | Contested at time of writing | | N6946-BH1 | Five | Current status of the failed-supernova interpretation | Text presents it as contested; may have resolved |
Rule for the proof pass: where a number has moved, prefer changing the number to changing the argument. Where the argument depended on the number, say so in the revised text rather than quietly re-fitting. Chapter Nine is entirely about a field that did this properly.
C.3 Epigraphs and permissions
All chapter epigraphs are drawn from public domain sources. Verified list:
| Chapter | Source | Status | |---|---|---| | Introduction | Heraclitus (attributed); Landauer, four-word aphorism, attributed | Public domain / fair use, brief and attributed | | One | Genesis 8:3, KJV | Public domain | | Two | Plato, Phaedrus, Jowett translation (1871) | Public domain | | Three | Genesis 1:2, KJV | Public domain | | Four | Rig Veda 1.1, Griffith translation (1896) | Public domain | | Five | Job 28:2, KJV | Public domain | | Six | Snorri Sturluson, Gylfaginning, Brodeur translation (1916) | Public domain | | Seven | Job 26:6, KJV | Public domain | | Eight | 2 Corinthians 4:18, KJV | Public domain | | Nine | After Ovid, Metamorphoses VIII — a rendering, marked as such | No permission required | | Ten | After Ovid, Metamorphoses VIII — a rendering, marked as such | No permission required | | Eleven | Völuspá, Bellows translation (1923) | Public domain | | Coda | None | — |
⚠️ Two notes. Chapters Nine and Ten both take their epigraph from Metamorphoses VIII. This is defensible — Erysichthon and the labyrinth are genuinely both in that book — but it reads as repetition when the chapters sit two apart. Consider replacing one.
The Nietzsche material in Chapter Eleven is paraphrased, not quoted, and the paraphrase should stay a paraphrase; Kaufmann and Hollingdale translations remain in copyright. Common's 1910 translation is public domain if a direct quotation is wanted.
No song lyrics, no poetry quoted at length, and no in-copyright prose passages appear anywhere in the manuscript. This was a deliberate constraint from the outset.
C.4 Known weak points
Stated here so that a reviewer does not have to find them.
The Four-Slot schema is applied to epistemic operators in two chapters. Chapters Eight and Ten treat measurement as the compressing operation, where the other nine treat a physical process. Chapter Eleven's Section 5.4 acknowledges this and calls it the strongest available objection to the book. A reviewer who wants to attack the framework should start there.
Chapter Six's neural oscillation section rests on a contested hypothesis. Binding-by-synchrony is flagged, but the section would be stronger if it leaned on circadian entrainment — which is solid — and treated cortical oscillations more briefly.
Chapter Seven's trauma mapping is the most hedged passage in the book and may still be too much. It survives on a structural distinction — destroyed versus unaddressable — and does not require the contested memory literature. If a reader in the field objects, the correct response is to cut the supporting paragraph rather than defend it.
Several "correction trail" case studies serve the same rhetorical function. BICEP2, the solar neutrino problem, the perytons, the glia ratio, the diamond planet, Andromeda. Six is arguably two too many, and a reviewer may find the pattern insistent. My own view is that they are each a different failure mode and the taxonomy is the point, but the objection is reasonable.
The book has no index and no glossary. For a text that uses `[VERIFIED]`, `[SOURCED]`, `[BOUNDARY]`, `[ILLUSTRATIVE]`, "Four Slots" and "the ledger" as terms of art, a two-page glossary would be a kindness.
