They claim it "began as an icy planetesimal that was irradiated at low temperatures by cosmic rays during its interstellar journey, and experienced warming during its passage through the Solar System. This explanation is supported by a large body of experimental work." But Avi Loeb disagrees: “In a new paper published recently in Nature -- https://www.nature.com/articles/s41586-022-05687-w Acceleration of 1I/‘Oumuamua from radiolytically produced H2 in H2O ice -- Jennifer Bergner and Darryl Seligman suggest that the peculiar acceleration observed by the first known interstellar object `Oumuamua, can be explained if `Oumuamua was made of water ice which was partly dissociated into hydrogen by cosmic-rays along its interstellar journey. In the abstract of the paper, the authors admit that past models involving a pure hydrogen iceberg or a pure nitrogen iceberg do not work due to theoretical or observational inconsistencies. In fact, the hydrogen iceberg model was proposed in a previous 2020 paper by Darryl Seligman himself. A few months later, Avi wrote a paper with Thiem Hoang, showing that heating by interstellar starlight would destroy hydrogen icebergs too quickly and not allow them to reach the solar system from their likely formation sites of giant molecular clouds. https://www.nature.com/articles/s41586-022-05687-w Read Hoang and Loeb's response paper: https://lweb.cfa.harvard.edu/~loeb/Hoang_Loeb_23.pdf Essay: https://avi-loeb.medium.com/oumuamua-was-not-a-hydrogen-water-iceberg-1dd2f7a6107f https://arxiv.org/pdf/2208.00092.pdf https://www.theguardian.com/world/2023/mar/24/harvard-physicist-pacific-expedition-first-interstellar-meteor Subscribe to the Jordan Harbinger Show for amazing content from Apple’s best podcast of 2018! https://www.jordanharbinger.com/podcasts Please leave a rating and review: On Apple devices, click here, https://apple.co/39UaHlB On Spotify it’s here: https://spoti.fi/3vpfXok On Audible it’s here https://tinyurl.com/wtpvej9v Find other ways to rate here: https://briankeating.com/podcast Support the podcast on Patreon https://www.patreon.com/drbriankeating or become a Member on YouTube- https://www.youtube.com/channel/UCmXH_moPhfkqCk6S3b9RWuw/join To advertise with us, contact advertising@airwavemedia.com Learn more about your ad choices.

0:00.0	There was a paper that I've written with the director of AARO at the Pentagon.
0:10.6	There is an organization collecting all the data about unidentified aerial phenomena.
0:15.0	In that paper we mentioned in the introduction the possibility that you can have a mother ship
0:22.0	that releases a lot of small probes.
0:24.0	And the reason I came across this idea is because
0:27.0	Omoa-Mua share the same distance of closest approach
0:30.0	and the same speed as an
0:33.2	interstellar meteor that was discovered seven months before it in March
0:38.6	2017 and it was detected by the US government and put in the meteor catalog and together with my
0:47.1	student Amir Siraj we identified it as moving too fast to be bound to the sun so we
0:52.1	identified it as an
0:53.0	interstellar meteor of very high material strength because it burned up in the lower
0:56.9	atmosphere of the earth. This was the second interstellar meteor. We
1:00.0	discovered another one from 2014, but what was special about the 2017 one
1:05.2	is that it shared the same distance
1:08.0	at closest approach to the sun
1:09.6	and the same speed at that distance
1:12.0	as Hormuamuadid. But that led me to suggest a possible scenario.
1:16.0	Of course, the purpose of any extraterrestrial technological gadget depends on what the senders wanted to use it for or it could be just
1:23.8	space trash you know we when you go to the ocean you find a lot of plastic trash
1:29.8	and it indicates that there are there is a technological civilization out there.
1:34.0	In fact, the mass of this trash will exceed the mass of fish in the oceans by 2050
