I guess some questions to consider are : is space infinite? CAN expansion continue? and if it continues, won't the effects of gravity lessen?
I find this theory highly dubious. Wouldn't increasing speed of expansion need increasing energy? What about the Law of entropy?
However, I agree that questions like these usually call to mind the question of a Creator.
Blessed be Your name, when the sun's shining down on me, when the world's "all as it should be," blessed be Your name!
Blessed be Your name on the road marked with suffering, though there's pain in the offering, blessed be Your name!
Every blessing You pour out I'll turn back to praise. When the darkness closes in, Lord, still I will say...
Blessed be the name of the Lord!
Blessed be Your name!
