This does not sound very promising - grandiose and superficial. You get better music by starting with a smaller set of ideas that you actually understand. Two pieces that come to mind are Toru Takemitsu's "From Me Flows What You Call Time", Morris Pert's "The Ultimate Decay" and Reginald Smith Brindle's "Andromeda M31" (the last is particularly good, an evocation of a vast cloud of stars by means of a vast cloud of notes - but it's for solo flute, so it uses both austerely minimal resources and fantastic virtuosity).

Lots of composers have done this sort of thing, I was listening to one of Scriabin's attempts last night. Cage's "Atlas Eclipticalis", most of Xenakis's early work, Charles Dodge's "Earth's Magnetic Field", Messiaen's birdsong music. The original of the genre is probably Haydn's "The Creation" and "The Seasons", which between them cover pretty much the same ground as your pal's project only he did it more than 200 years ago. What counts is how much musical imagination you add to the extramusical ideas.
