Because light comes at us in all directions and the universe is bigger in light years than what light has had time to travel.
So, if the earth were displaced a few billion light years in any direction, than that few billion light years would become invisible to us while another portion of the universe would suddenly become visible.
This also means that light can never go from one end of the univrse to the other given its current size and rate of accelerating expansion.
If today you can take a thing like evolution and make it a crime to teach in the public schools, tomorrow you can make it a crime to teach it in the private schools and next year you can make it a crime to teach it to the hustings or in the church. At the next session you may ban books and the newspapers...
Ignorance and fanaticism are ever busy and need feeding. Always feeding and gloating for more. Today it is the public school teachers; tomorrow the private. The next day the preachers and the lecturers, the magazines, the books, the newspapers. After a while, Your Honor, it is the setting of man against man and creed against creed until with flying banners and beating drums we are marching backward to the glorious ages of the sixteenth centry when bigots lighted fagots to burn the men who dared to bring any intelligence and enlightenment and culture to the human mind. ~Clarence Darrow, at the Scopes Monkey Trial, 1925
Politics is supposed to be the second-oldest profession. I have come to realize that it bears a very close resemblance to the first. ~Ronald Reagan
