english: Einstein realized that if space were empty, if the universe were empty, it would be like this picture, except for maybe without the helpful grid drawn on it.
non_english: Einstein si uvedomil, že keby bol vesmír prázdny, ak by bol vesmír prázdny, vyzeralo by to ako na tomto obrázku, snáď okrem pomocnej mriežky, ktorá je na ňom nakreslená.
