Great questions! I'll take a shot...

Is that part of the canvas that science cannot fully explain at present the realm of God?
Or is it only that portion that science can never explain?

Well, I believe that it's all the realm of God. I believe that scientific truth informs our understanding of God. All truth does.

How does one know what science will never be able to explain?

We really don't. My issue is as much with those who parrot "Because God said so," at everything, as it is with those who assume that everything can be expalined without God.

Both are intellectually lazy dogmatists.

And how do we know that what science will never be able to explain is the handiwork of some sentient force? Isn't that a leap of faith?

Yes, ultimately this is something we can only "know" by faith.

A companion question here might be, "What scientific methods can establish an inference to sentient force?" I maintain that the methods of statistics and probability, allied with observation, can now rigorously establish such an inference.

...and I should add that, conversely and by the same rigorous methods, such things as algorithms, natural laws and random processes can be shown to have a vanishingly tiny probability of acting as first cause -- in both the origin of life and the origin of the physical universe.
