Interstellar Meteors are Outliers in Material Strength
Siraj and Loeb infer unusually high breakup pressures for two reported meteors from catalogue inputs. IM1 reuses the earlier analysis; IM2 remains a candidate whose interstellar origin requires confirmation. Breakup pressure is a model proxy, rather than a laboratory composition measurement. Early weak flaring, corrected light-curve normalization, sensor bias and small-number population assumptions qualify the conclusions. This paper supplies no new government approach or classified-data receipt.

How we check sources
Not checked yet
- IM1 shares the prior catalogue and reported DoD-confirmation chain. IM2 remains conditional. The 273-fireball comparison, rank and Gaussian calculations are model-dependent, rather than calibrated population-hypothesis probabilities. Sensor selection, missing uncertainties and a cited Chelyabinsk strength bias of two to three times remain.
- Figure 1 caption and prose swap distribution parameters; the three-object inclination discussion prints a square with incompatible arithmetic. These discrepancies remain unrepaired. The early weaker IM2 flare and normalization correction limit a unique composition interpretation. Raw sensor records, calibration, laboratory tests and code were not supplied.
- Two-case abundance and metal-budget estimates depend on membership, selection, rate, mass and focusing assumptions. Ordinary supernova fragments and Oort-cloud reservoirs remain possibilities. Work-level partial Breakthrough Prize Foundation and Galileo Project support lacks individual recipient, award and date. The author-hosted DoD letter is only a reference in this lane; original authentication, correspondence, funding records, journal versions and current census remain gaps.
