Your post regarding expansion of the universe suggests that you do not realize that it is space itself that is expanding and just carrying the galaxies along with it. To quote from your post:
***If the universe is expanding and all galaxies are racing away from each other, then what is it that space is moving in to - God's home, his little bungalo of love? What lies outside of the known universe? As the universe expands is it gobbling up this unknown area?***
First of all the galaxies in our local group are not racing away from each other. Actually the two largest galaxies are being pulled towards each other and will someday collide if they keep going.
The known universe is limited by the amount of time that light has had to reach us, namely the age of the universe. We cannot see anything beyond about 15 billion light years. More important, because space is expanding, the amount of the universe that we can see is shrinking. So as space expands, the known universe contracts.
So there is no unknown area or volume that the universe is expanding into. What lies outside the known universe is just more universe. Someday it will be previously known universe.
Regarding god, my view is that our closest connection to god is via dark matter. That medium surrounds us and interpenetrates us. So that aspect of god is right here with us. It is not something outside of the universe. Since dark matter makes up about 90% of the mass of the universe, it is more accurate to say that god is the universe than is outside the universe.
I have a scientific theory of how dark matter is the closest thing to god that we can experience. Everybody else on this forum has heard about it many times, so I am reluctant to repeat it again, but will if encouraged, and vice versa.
