Zealots of all stripes typically have blinders on. I like to do my own thinking. I was lying in bed this morning thinking about the big bang concept. The universe is usually depicted for understanding as an expanding balloon, suggesting that the galaxies are on the surface of the balloon, each departing from the others. That model implies that there is an unoccupied void within the balloon where the air or helium is. Can a galaxy on one side of the balloon see one on the other side THROUGH the balloon, or does it have to look around the curve of the surface? Is the balloon model an oversimplification? Any of you astronomy chaps out their care to speculate for the benefit of a mere forester?
