The earth revolves around the sun.    (01) Each individual atom in/on/of the earth revolves around each individual atomic nucleus of the sun. Each conjoined set of atoms in/on/of the earth revolves around each individual atomic nucleus of the sun. [How many facts are we up to now if each of the above is expanded?]    (02) > 2.

C at sea level.    (05) This seems like a definition of a term, not a fact (and a non-standard definition at that, not mentioning initial temperature or pressure). If it were a fact, then it would encompass a fact for each cc of water.    (06) > 4. Chemical X contains Y calories of available energy. (of course > substituting where appropriate)    (07) Do you mean a specific mass of Chemical X ? There are certainly a large number of ways to pick an amount of Chemical X of that mass.    (08) > Are these not facts? Are they not countable?    (09) If the universe has a finite amount of Chemical X, then 4) encompasses a finite number of facts. We've left a google in the dust a long time ago.    (010) They are countable in that they are not infinite.    (011) > Again, aside from bending the space-time continuum, or dismissing laws of > nature like thermodynamics...I fail to see the need for relativism > here...or, what am I missing?
