What 'force' was this?

[CoxRox]

All studies are ongoing. You're going to stretch my "never leave a man behind" business. Propose your force, your mechanism, your source, whatever you like. Since no explanation thus far has satisfied you. We'll go through your rough ideas one by one.

1: It was not a raygun in the ceiling (though this is easily as plausible as the supernatural)

2: It was not the "kinetic energy" of the people around you, else you should re-write your story as to make it clear that you were pushed down.

3: It was, of course, again, in your head.

Which one would you bet the farm on?

I'm quite happy for you to leave me to my 'undecidedness'.
