“The night sky shouldn't be so dark," Peter had told her. "If the universe is endless, then starlight should fill all the empty spaces. Light doesn't stop until it hits a surface - so why the dark spaces? From where we stand on Earth, all we should see is light." "Maybe the universe isn't limitless, then," Alice had said. "Or the universe is expanding," Peter had said. "And the stars are too young, and all that distant light is still stretching to reach us. And until it does, the night lies dark.”
