large matchbox full of interstellar gas would contain about a hundred atoms

Categories: Comparisons

An example of quotidian comparisons used to explain science:

"The interstellar gas is certainly extremely rarefied. On average over the whole galaxy a large matchbox full of it would contain only about a hundred atoms. This my be compared with the material in a star, like the Sun, where on average a matchbox full would contain about a hundred million million million million atoms."

Fred Hoyle (1960) The Nature of the Universe (Revised ed.)
