quote [ The galaxy is rich in grease-like molecules, according to astronomers, who used a laboratory to manufacture material with the same properties as interstellar dust & used their results to estimate the amount of "space grease" found in the Milky Way. They found that there are about 100 greasy carbon atoms for every million hydrogen atoms, accounting for between 1/4 and 1/2 of the available carbon. In the Milky Way Galaxy, this amounts to about 10 billion trillion trillion tonnes of greasy matter, or enough for 40 trillion trillion trillion packs of butter. Prof. Tim Schmidt: "This space grease is not the kind of thing you'd want to spread on a slice of toast! It's dirty, likely toxic & only forms in the environment of interstellar space". ]
