Did you knew that one galaxy has between 100,000,000,000 si 1,000,000,000,000 stars and in the Universe are over 50,000,000,000 galaxies? From Earth we can only see about few thousand stars . I wonder if anyone tried to proved those numbers or tried to imagine how big is the Universe!? We can say that we are an atom from a tiny piece of sand from Sahara Desert and I don’t think that’s small enough for the greatness of our Universe….and try to imagine that the desert is limited, is the Universe limited?, I don’t think that we’ll find that answer in our lifetime . And the second question is: are we alone in the Universe?…
