作曲 : Ben Ford/Kevin Rikken
The universe
The Milky Way galaxy is our cosmic home
But it is far from being the only galaxy in the universe
To get a better understanding of the composition and evolution of our universe
Astronomers try to answer a deceptively simple question
How many galaxies are there in the universe?
For a long time it was thought
That that the entire universe consisted of our galaxy alone
Beyond this limit
Just how far it goes is yet an unanswered question
The universe continues
The universe
