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 şunu farketti, uzay boş olsaydı, evren boş olsaydı, bu resim gibi olurdu, üzerine eklenmiş yardımcı kılavuz çizgiler hariç belki de.
