Harlan Ellison? Frank Zappa? Anonymous?

Question for Quote Investigator: There is a popular quotation that expresses the following idea:
Hydrogen and stupidity are the two most abundant materials in the universe
This notion can be expressed in many different ways. One version has been credited to the speculative fiction writer Harlan Ellison, and another version has been ascribed to the musician Frank Zappa. Would you please examine the provenance of this statement?
Reply from Quote Investigator: This saying is highly mutable and difficult to trace. The earliest evidence known to QI appeared within an interview of Frank Zappa conducted by Michael Bloom which was published in the periodical “Trouser Press” of New York City in February 1980. Boldface added to excepts by QI:1
At heart, though, Zappa just grits his teeth and expects the worst. “When things are really stupid, when they’re really stupid, I’m not surprised. What surprises me is if things turn out good—anything that rises above the general level of mediocrity. Wonderful is something else, you know. I just think the norm of the universe is stupidity. Stupidity is like hydrogen; it’s everywhere, it’s the basic building block of the universe.”
In 1981 the periodical “The Event” of Park City, Utah published an interview of Frank Zappa conducted by Steve Chapman. Zappa spoke again about hydrogen and stupidity:2
Zappa: I’m not scared of anybody but you have to remember that another cornerstone of my philosophy is that Science believes that hydrogen is one of the building blocks of the universe. I disagree. I say that the most plentiful substance in the universe is stupidity. There’s more stupidity per square foot in this universe than anything else. People can go on talking about hydrogen as much as they want to, but stupidity is where it’s at.
In 1985 Harlan Ellison published “An Edge in My Voice” which primarily consisted of a set of columns written during the 1980s. Ellison updated the content by adding introductory remarks for each column under the section title “Interim Memo”. The following passage was from one of these supplementary introductions:3
At a lecture I gave in Grand Forks, North Dakota in March of this year, someone asked me how do we finally knock the fools and obscurantists and believers in craziness out of the box once and for all. I told the woman that we can’t. Apart from hydrogen, the most common thing in the universe is stupidity.
