Scientists determine 'Oumuamua isn't made from molecular hydrogen ice after all:

The debate over the origins and molecular structure of 'Oumuamua continued today with an announcement in The Astrophysical Journal Letters that despite earlier promising claims, the interstellar object is not made of molecular hydrogen ice after all.

The earlier study, published by Seligman & Laughlin in 2020—after observations by the Spitzer Space Telescope set tight limits on the outgassing of carbon-based molecules—suggested that if 'Oumuamua were a hydrogen iceberg, then the pure hydrogen gas that gives it its rocket-like push would have escaped detection. But scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) and the Korea Astronomy and Space Science Institute (KASI) were curious whether a hydrogen-based object could actually have made the journey from interstellar space to our solar system.

"The proposal by Seligman and Laughlin appeared promising because it might explain the extreme elongated shape of 'Oumuamua as well as the non-gravitational acceleration. However, their theory is based on an assumption that H2 ice could form in dense molecular clouds. If this is true, H2 ice objects could be abundant in the universe, and thus would have far-reaching implications. H2 ice was also proposed to explain dark matter, a mystery of modern astrophysics," said Dr. Thiem Hoang, senior researcher in the theoretical astrophysics group at KASI and lead author on the paper. "We wanted to not only test the assumptions in the theory but also the dark matter proposition." Dr. Avi Loeb, Frank B. Baird Professor of Science at Harvard and co-author on the paper, added, "We were suspicious that hydrogen icebergs could not survive the journey—which is likely to take hundreds of millions of years—because they evaporate too quickly, and as to whether they could form in molecular clouds."

    Marissa Van Eck FAKENAME NIGGER CUNT Azuma Hazuki: So "that was NOT me posting" https://soylentnews.org/comments.pl?noupdate=1&sid=37033&page=1&cid=985641#commentwrap [soylentnews.org] which YES, you said when you LIBELED me publicly BEFORE it with YOU saying "So that's a "yes" to schizophrenia/schizoaffective disorder and a "no" to "am taking meds for said disorder" LIBELING ME then...?" per YOUR https://soylentnews.org/comments.pl?noupdate=1&sid=37033&page=1&cid=982854#commentwrap [soylentnews.org] you stupid pitiful FAKENAME fuck online LIAR piece of fucking SHIT NIGGER?

    OR

    Was it when I GOT YOUR REAL NAME & found you are a satanist/anti-god HERE https://redeeminggod.com/sermons/luke/luke_7_36-50/#comment-269796 [soylentnews.org] also which most ALL you "LEFTIST" LOSER weirdos usually are (which YES, in THIS other exchange "Why do you assume that you finding discussion threads on other sites with me in them will scare me?" quoted from https://soylentnews.org/comments.pl?noupdate=1&sid=38720&page=1&cid=1028402#commentwrap [soylentnews.org] you DID admit FINALLY to saying it was you - ESPECIALLY AFTER dozens of doctors RECENTLY seconded me on Hydroxychloroquin + Zinc (& Vitamin D3 imo along w/ other things I noted that are anti-viral + antibacterial like RAW GARLIC too)).

    Do me a favor - DENY ANY OF THOSE, please & I will continue PROVING YOU ARE A NIGGER SHITBAG LOSER, devil... as I already DID here https://soylentnews.org/comments.pl?noupdate=1&sid=38720&page=1&cid=1028211#commentwrap [soylentnews.org]

    The TRUE BEAUTY of SATANIST FUCKS like YOU (antigod assholes)? TRUTH & FACT DESTROYS LIBELOUS DEVILS LIKE YOU - just like I did you & OTHER AHOLES who doubted what I wrote on what is NOW PROVEN TRUE by DOCTORS, admitted in mainstream media etc. (as I showed in those links' exchanges above easily) & especially LATELY by DOZENS of doctors (I have proof from pros - NOT LIBEL like you did to me PUBLICLY & I can still FRY YOU FOR IT FUCKER, live in fear fuck) MINUS any psych pros backing you.

    SAY 1 THING, YOU STINKING LIBELOUS NIGGER FUCK & I will CONTINUE LEVELLING YOU PUBLICLY with facts - not libel as you tried on me, stupid "Marissa von DUMBO", lol - please, say 1 thing & the BEATING on you, PUBLICLY will continue in this thread where you will have a HELL of a TIME "downmod burying it" via downmod brigades doubtless ONLY yourself via multiple sockpuppet accounts etc. (downodding to HIDE it? FORGET IT vs. me - everyone sees you @ it now, lol - thanks, just as I SAID "your kind", demonic SWINE/antigod LOSERS, always do).

    WHY SHOULD YOU FEAR LIBELING ME PROJECTING IT NOW, TRYING TO HIDE IT TOO?

    TOUGH HIDING YOU LIED about LIBELING ME, especially via INHERENTLY DAMAGING STATEMENTS libeling me as you did see GOLDWATER RULE below too fuckface CUNT you are (wikipedia proof https://soylentnews.org/comments.pl?noupdate=1&sid=37033&page=1&cid=985366#commentwrap [soylentnews.org] & you said "No jury or judge would back it" here https://soylentnews.org/comments.pl?noupdate=1&sid=37033&page=1&cid=985353#commentwrap? [soylentnews.org] Ok - like I said earlier here which you TRIED TO DOWNMOD HIDE as I knew you HAVE to (everyone sees it anyhow) - TRY ME FUCKER - say 1 thing you COWARDLY STUPID LITTLE FUCK & we'll SEE what happens to you, fuckface CUNT you are).

    As I said "DO YOU WANT TO BE SUED" for breaking the GOLDWATER RULE? See here again https://soylentnews.org/comments.pl?noupdate=1&sid=37033&page=1&cid=985329#commentwrap [soylentnews.org] for YOUR (& everyone else's) reference of YOUR LIBEL of myself

    APK

    P.S.=> Oh, I am going to have a FIELDDAY on YOUR ASS fucker - catching you not ONLY IN LIES above, but also in the fact you are a GODLESS fucking LOSER - come on, say something, question the above where you LIED fucker ("it was not me saying it" but it WAS in those links calling me a nutcase essentially when YOU SAID YOU DID NOT (because it IS grounds for SUING THE LIFE OUT OF YOUR WORTHLESS ASS because your statements are NOT BACKED BY actual psychiatric pros in professional psychiatric grounds LIBELING ME)) - oh, you are NEVER going to LIVE THIS DOWN & believe you me - I am going to MAKE SURE you don't - live with your HUMILIATION loser... apk
