Once you go through a black hole, 
you never come back.
.لا يمكنك العودة أبدًا بعد المرور خلال ثقب أسود
Einmal dort drin kommt
man nicht zurück.
Y si entráramos, no podríamos salir.
Y si entráramos, no podríamos salir.
Une fois dedans, 
on n’en ressort plus.
Una volta dentro un buco nero
non si torna più indietro.
Quando você passa por um buraco 
negro, não consegue voltar nunca mais.
Попав в чёрную дыру,
вы уже не вернётесь.
