==Explanation==
{{incomplete|This page was created by the carbon in the universe . Don't remove this notice too soon.}}
The supposed "chemical formula for the universe" merely lists the numbers of atoms of each element. As is common practice for real compounds that contain organic structures or substructures, the numbers of atoms of carbon and hydrogen are listed before all of the others; the others are listed in alphabetical order. There are estimated to be 10<sup>80</sup> atoms of hydrogen (H), by far the most common element in the universe. The next most common element, helium (He), is a long way to the right in the list, and out of view, but would be about a third as many as the hydrogens.

These numbers are large, but they are not nameless. Using the {{w|long and short scales}}, these numbers can be described as:

The matter originally created in the Big Bang was unbound protons and neutrons. In the first few minutes, {{w|Big Bang nucleosynthesis|some of these combined to form lightweight nuclei}}, but most remained as protons, i.e. the nuclei of hydrogen atoms. Other, more complex atoms formed later as a result of {{w|stellar nucleosynthesis}}, up to atomic mass 56. Still more massive nuclei have been formed via {{w|supernova nucleosynthesis}}. Although the proportions of these atoms depend in a complex way on the fusion processes involved, and on the stabilities of those nuclei, the most massive atoms are generally both less favored to form and short-lived, so their elemental abundances in the universe are very small. As shown above, the number of americium (Am) atoms is much smaller than those of any other element in the visible part of the "formula". There are slightly fewer atoms of americium in the entire universe than the total number of atoms of hydrogen and oxygen in 1.0&#8239;L of liquid water.

This may be poking some fun at the relative usefulness (or rather, uselessness) of chemical formulas for large organic molecules. While it is a useful concept for teaching people about chemistry and balancing equations, and it was useful in the early days of chemistry to try to categorize and learn about molecules via stoichiometry - it does not give much useful information. For example even the simple formula C<sub>11</sub>H<sub>15</sub>NO<sub>2</sub> has 302 registered isomers.{{actual citation needed}} Many of them are NOT good to eat.{{cn}}
