Fake News ? Dark Matter is Greasy..Astronomers too clean to find it ? Calling for Grease Monkeys

Aliphatic Hydrocarbon Content of Interstellar

I have no idea if this is fake news or not but indeed cold grease particles emit light at wavelengths and brightnesses we can’t detect. So maybe some dark matter is made of grease ?? Astronomers need help from grease monkeys ?

The Milky Way contains about 10 billion trillion trillion tonnes of greasy matter — or enough for 40 trillion trillion trillion packs of butter — according to research from a joint study by astronomers at the University of New South Wales (UNSW) and Ege University in Turkey

the finding were published in the royal astronomy society ( I am a member so I know its not fake, hmm am pretty sure) monthly notices

In previous blogs i have argued that we need to make science’ intimate’ because so much that we know about is not accessible to human senses, even augmented and extended. Well here is the proof in the pudding ! we need grease monkeys to help us understand the structure of the universe

Abstract

There is considerable uncertainty as to the amount of carbon incorporated in interstellar dust. The aliphatic component of the carbonaceous dust is of particular interest because it produces a significant 3.4 μm absorption feature when viewed against a background radiation source. The optical depth of the 3.4 μm absorption feature is related to the number of aliphatic carbon C-H bonds along the line of sight. It is possible to estimate the column density of carbon locked up in the aliphatic hydrocarbon component of interstellar dust from quantitative analysis of the 3.4 μm interstellar absorption feature providing that the absorption coefficient of aliphatic hydrocarbons incorporated in the interstellar dust is known. We report laboratory analogues of interstellar dust by experimentally mimicking interstellar/circumstellar conditions. The resultant spectra of these dust analogues closely match those from astronomical observations. Measurements of the absorption coefficient of aliphatic hydrocarbons incorporated in the analogues were carried out by a procedure combining FTIR and 13C NMR spectroscopies. The absorption coefficients obtained for both interstellar analogues were found to be in close agreement (4.76(8) × 10−18 cm group−1 and 4.69(14) × 10−18 cm group−1), less than half those obtained in studies using small aliphatic molecules. The results thus obtained permit direct calibration of the astronomical observations, providing rigorous estimates of the amount of aliphatic carbon in the interstellar medium.
