Most people don't base their morality on religion in spite what they say. If you ask people, "If you didn't believe in God, would you go out and kill your neighbour?" Most people will say, "No".

As far as the scientific community in 1917 was concerned, the universe was static and eternal, and consisted of a one single galaxy, our Milky Way, surrounded by vast, infinite, dark, and empty space. This is, after all, what you would guess by looking up at the night sky with your eyes, or with a small telescope, and at the time there was little reason to suspect otherwise.
