What is qi?

[No_Know]

What is it?

Simple explanations only please.

I think I know what it is but I would like to hear what other people think it is also. I will post my definition after a few replies.

I No_Know, however, I think qi might be considered to be something like frequency modulation, on a quark level-allowing for interaction outside the Human body and greater efficiency of atomic/cellular structures within a Human body.
