This video was published in 2011. VY Canis majoris was re-estimated and is not as much big as we thought. Is real size is little much bigger than 2/3 of is size in the video. So there are six stars a little bigger.

SUBJECTS TO DEBATE :

How do you feel to be so small in the universe ?

Do you think we will one day understand better the universe ?

For you, is it possible to find a way to go really far away in the universe ?

Do you think that we can find others planets to live in ?
