Darkness is mean scared or some ghost things, but my stand point is It's not really a bad thing .Instead,it is a medium for me to express my feeling. In a darkness place ,i may enjoy in this environment and think the old thing or khalil's song ,it makes me charm and comfortable.

BlackHole is a thing that I always in a fantasy world .That meaning is similar to darkness, but it's full of fantasy and future .It's not like darkness full of old .Some inventors think that we can use BlackHole to a medium and make a machine to pass thought  the  BlackHole.It may go to the past or future .If this invention sucesses, I think i will try to control this machine to visit in the past and future .I look forward it ..
