अनुबाद - अंग्रेजी-फ्रान्सेली - Gravitation

Why not "la gravitation" (physics)?
Not sure, but I would suggest "responsable des gens tomber amoureuse"...

"pesanteur" is more easily understandable for French speaking people
About "gens", which is plural, it's "masculin pluriel" (eh yes, when there's two people, a male and a female, the adjective is "masculin pluriel" in French, Frenchs are big machos anyway -got a sample recently!-)

Oh yes, of course masculin (and "la pesanteur" was the other word even in my dictionary).

I was just thinking those two words, gravitation and falling, where I was concerned with the idea that responsibility should refer to falling and not to the people i.e. gravitation force causes objects to fall (and not float in the air) but not when it is question about love. Did not see anything else.

And again, I am astonished how complex even the short sentences are, the interpretation and the connotations that come to your mind.

By the way, the idea I was after here would be lost if translated into finnish because we don't use the verb to fall here in any sense, only change the verb a bit:
to love=rakastaa, to fall in love=rakastua
(to get/make somebody to love=rakastuttaa,
to get s-y to fall in love=rakastututtaa...)
Not the best verb as an example of the treatment
but that's the idea...
