1700-1800
There are periods when technological leaps change humans and change human perceptions forever. This was one such century. One young German family, a brother and sister, William and Caroline Herschel. William had taken a keen interest in astronomy as a child and as the wars in Europe would evolve he migrated to England where his fascination bloomed. His contribution to the science of the study of the universe was through his improvement of the Telescope and Newton's refractor lens. It allowed for the first time to sees the Milky Way as different than the canopy that it appears as to the naked eye or even with lesser telescopes. The Universe now had depth, real depth. Light and movement could be calculated in millions of years and not in the Genesis model of 6000 years.
Nebula, once thought to be gases left by the hand of God and of no real importance were visible as stars and galaxies millions of light years beyond our own Galaxy. And the perception of God began to evolve as well with this new science. Distant, vacant, removed, the Hand behind the curtain was being revealed. Nothing would ever be the same.
