Sometimes I often think, what do you think is the purpose of life? Money, love, power, fame, are these things important to us?

Perhaps we should spend more time exploring the mysteries of the universe. The earth is a bit big for humans, but it is insignificant in the entire universe.

We should vigorously develop science and technology to see the scenery outside the universe and explore whether the universe has an end? What is the end of the universe? Is it really like some people say that we are in a cage?
