Well… now i understand why there was concern about what happened on the other thread happening here.  I certainly don’t want it to.

Here’s a couple of links that i found a little bit helpful just in terms of knowing technical terms for grammar:

In what sense is it possible that we go to the seaside tomorrow?

The only sort of situation in which i can see someone using the exact phrase “it is possible that we go to the seaside tomorrow” would be in relation to a plan, a script, or something of the sort.

Is that relevent? 

(I’m not really dedicated enough to keep up with that other thread, so i’m posting here, where i hope the atmosphere will be more careful, less verbose).

“It’s possible that we’ll go to the beach”—can express predictive uncertainty, personal indecision (I haven’t made my mind up, yet), or a belief in imperfect causality.

“It’s possible for us to go to the beach”—expresses an ability… meaning that if we decide to do it, then that decision will cause the action.

(This says nothing,
of course,
about causality
outside of that
specific link.)
