I already said I don't know. Your turn.

Ok, so, the Bible does not say that God created darkness (and in the same way, He did not create sin). Darkness is a result of a lack of light. In other words, without light, there can be no darkness.
In the same way that darkness exists (because God created light), gravity exists because God created matter. In other words, gravity is a result of God creating matter.
Do you get what I'm saying?
This does not contradict any cosmology verses in the Bible, but is in fact consistent with them.
For instance, In Genesis 1:1-2, God created the heavens and the earth, and the earth was void and without form.
Might I suggest that the word "earth" in verses 1-2 does not mean planet Earth, but "earth," as in what Earth is made of, rock.
Instead of imagining a single, earth-sized blob of matter, though, imagine all of the matter in the universe in one giant blob, and this is what God used to make every celestial body in the universe, from the tiniest moon, to the largest star, in galaxies that span hundreds of thousands of light-years of space, which make up the tendrils of a superstructure of galaxies like the structure of a giant sponge, and the earth is almost dead center in it.
And then, on day 4, God stretched out the heavens, so that the universe was even bigger, drawing out the light from the stars like he drew out the plants from the ground we stand on.
