Actually, if the star or region of space is anything similar to our own, O2 is definitively a sign of life. Not animal life, but at least plant life, to crack the O2 out of the CO2 with photosynthesis.[[User:Seebert|Seebert]] ([[User talk:Seebert|talk]]) 14:00, 27 April 2015 (UTC) | Actually, if the star or region of space is anything similar to our own, O2 is definitively a sign of life.

:The explanation currently covers links that show that not all oxygen will be created because of life, and not all life (even 'as we know it') will necessarily require/produce a significant oxygen signal. But there seems to be a missing middle-bit in that oxygen initially seems to have been a smothering 'industrial pollutant' by early (oxygen splitting) life-forms until other life-forms developed the machinary to use this oxygen as part of their own energy mechanisms (creating the eventual two-way dynamic of CO<sub>2</sub> and O<sub>2</sub> production/usage between the ''major'' groups of life) and thus making the unstable free oxygen both an indicator of life and an indicator of the ''capability'' of life (by mainstream terrestrial standards of biology, of course).

I'm pretty sure the original lyric for "This Kiss" is "it's centripetal motion" (see: http://www.sweetslyrics.com/59372.Faith%20Hill%20-%20This%20Kiss.html). I assumed the joke Randall was making was that centrifugal really is a force, Mr. Bond, even if Faith Hill doesn't know about it.
