Their estimates distinguish 12-object velocity and 180-object angular tests of two ejection models from a separate 12-object anisotropy test. Density, size, sampling and detection assumptions remain uncertain. White-dwarf, outer-cloud and interstellar-medium alternatives are retained. Discovery forecasts and an artifact conjecture are not observations. Manuscript comments and work-level grant support do not establish government access.","subjects":["Conditional population forecasts","Ordinary physical alternatives"],"people":["Avi Loeb"],"review":{"label":"Received written text and native layouts; originals and interpretation gaps","scope":"A specialist actually read all four supplied arXiv:2010.02214v2 pages, 14,206 normalized characters, and viewed four native layouts, all five figures, 19 bibliography entries and one footnote. Root reviewed the entire frozen final analytical report/evidence and independently verified its inventory; root primary-body reading is false. The first submission is dated 5 October 2020, revision 15 October and native draft header 16 October. Related journal DOI is metadata; the final journal body and v1 were not collated.","gaps":["The 0 and 50 km/s simulations, stellar distributions and approximate two-sigma sample forecasts are models, not independently observed populations. The 12 velocity, 180 angular and 12 anisotropy forecasts concern distinct tests. Mixed populations, uncertainty propagation, sample definitions and implementation remain unverified.","An inherited single-object density, uncertain sizes and brightness, ignored drag or stellar changes and survey selection affect forecasts. Several-per-year and up-to monthly or weekly rates concern different sizes and conditions. They are dated projections, not verified current discovery yields or an exhaustive census.","Uniform angle wording, isotropic sampling rules and Figure 4 probability labels, degree axis and normalization remain unresolved without code, sample sizes, seeds or numerical data. No silent correction, established sampling error or simulation replication is claimed.","Conventional white-dwarf ejection, outer exo-Oort clouds, turbulence and interstellar-medium exchange remain alternatives. The interstellar-meteor claim and cited observational originals were not received here. A suggested artifact subpopulation is conjecture, not detection, custody or origin confirmation.","Manasvi Lingam is thanked for manuscript comments without original messages or dates. Partial Breakthrough Prize Foundation support is at work level, without an individual recipient, grant ID or Starshot earmark. Journal/version collation, all 19 cited bodies, linked survey page, code, catalogues, current instruments and fine original-glyph assurance remain gaps."]},"familyId":"ARXIV-2010-02214-V2","citationUrl":"https://bioparity.io/sources/S7719","citation":"Amir Siraj, Abraham Loeb.
