The universe is so big

Think that all we ever know, all we ever see , etc is all on this tiny blue planet...

but just think: our sun is a star.
We live in the milky way galaxy, and theres around 400 billions star systems in our galaxy... each star can have their own planets , etc

And also, they also say that the universe contains billions of galaxy....

That would be so nice to have the technology to visit other star systems... but not for now
