I hold that the specific, concrete future exists in the form of probabilities. Omniscience comprehends all those probabilities.

Say Sophiee, Gideon and I are all standing around a pool table. I am right next to the table, Sophiee four feet distant, Gideon eight feet distant. The present moment is t = 0. One second ago (t = -1 sec), I set two billiard balls in motion on top of the pool table, in such fashion that, absent some intervention, one second from now (t = 1 sec) they will collide.

There is a nonzero probability that no one and no thing will intervene, and thus they will collide. There is another nonzero probability, that I will reach over and remove one of the balls from the table, and thus they won't collide. There is another, smaller, nonzero probability that Sophiee will so intervene. There is another, still smaller, probability that Gideon will so intervene.

There is also a nonzero probability that someone in a low-flying plane overhead will toss a fully dressed Christmas ham out the window, which will crash through the roof of the building and roofs and floors in between and ultimately onto the pool table in such a way that the balls don't collide. This probability is infinitesimally small, but nonzero.

Omniscience comprehends what all those probabilites are, and their relative values at every given moment. Until the event itself occurs, omniscience does not comprehend which of them will, in fact, occur; given the presence of persons possessing free will.
