Avi Loeb, Lucas Perry. futureoflife.org. July 9, 2021.
Loeb discusses independent observations and unnamed private-funder conversations. He explicitly says he lacks direct classified and incident-by-incident data. The review preserves that limitation alongside stronger technology-origin assertions, alternative explanations and proposed measurements. Private interest is reported discussion, with no funding commitment or operating-project receipt supplied.
Amir Siraj, Abraham Loeb. arxiv.org. September 12, 2019.
Siraj and Loeb argue that a roughly kilometer-scale Borisov nucleus better matches an assumed ordinary Oort-cloud mass budget. An eight-kilometer alternative produces substantial tension with that benchmark, without independently disproving the larger size. Their figure uses four points for three object families, including two alternative Borisov radii. Sparse Poisson bounds do not capture every observing or population uncertainty. This is a conditional argument using reported observations, not a new measurement campaign or artificial-origin finding.
■ Received written text and native layouts; originals and interpretation gaps
Hynek recounts his investigation work, a reported Air Force invitation and consultancy, and encounters with witnesses. He distinguishes secondhand reports from his own ambiguous observations and considers ordinary explanations. The reviewed book accounts do not independently authenticate appointments, original correspondence, case evidence or classified access.
