About

氣 (qi, ki, chi) as defined in the Oxford Dictionary, is the circulating life force whose existence and properties are the basis of much Chinese philosophy and medicine. Wikipedia has a longer definition, pointing out a couple of dozen potential meanings.

氣 is a purely hypothetical concept with neither grounding in current scientific theories nor basis in evidence based experimentation. For example, see the Sceptic's dictionary entry.
