旅行到宇宙边缘

Mercury, Venus, Jupiter, the Solar system, nebulae, the Milky Way, pulstars , galaxies, quasar, black holes, dark matter, the age of the universe, Earth, our home.....
Looking toward the stretching and boundless starry sky and the far and deep space, we only melancholy moan that we’re just mayflies amid the universe or an insignificant grain of millet in the boundless sea, and we are saddened that lifetime lasts for just a brief moment.
But after we live in new homes and find out the answers of secrets, what should we do?
We have to go back to social life, including eating, sleeping, loving, traveling, entertaining, working, being hurt, being sad and so on.
As a result, let's embrace the real life which mixes with sorrow and happiness, and look up the mysterious sky. Knowing much makes us more appreciate the life we have now.
