I would say that, all numbers begin with o must end with o. Thus the beginning or first digit 0, becomes the final number.

And that the curtain of the Kaaba holds the two o'o's meaning, that the house is the exact pinpoint of the Earth, going onto state even more then that, the exact pinpoint of the universe, meaning that it is the door or entrance to the infinity or eternal paradise, meaning that, when we pray, all our sins are going directly to the hosting Kaaba, meaning they, the sin, enters' paradise and that then is converted into a purity of returning the heart to the state of purification after sin. That the universe is the hosting suspension for the creation of paradise, speculative.

Speculation.
