| Sep 11, 2019 at 15:09 | comment | added | Starfish Prime | @MichaelStachowsky there's a lot of it about, and we have two examples of terrestrial bodies with thick, nitrogen-rich atmospheres. It also forms all sorts of interesting compounds, making it slightly more likely to remain bound up in an atmosphere or at least on a planet than its noble gas cousins. | |
| Sep 11, 2019 at 15:07 | comment | added | The Square-Cube Law | @MichaelStachowsky it is one of the most abundant elements in the body of any living being. Life as we know would not evolve in an atmosphere with low levels of nitrogen. | |
