imagine

the title above reminds me about John lennon's song. its a prety cool song..
and if i listen to this song, i feel like there are no borders, there are no limitations of life. i think there's so many possibilities of life. a few months ago, i see a forum about time traveling. so many people wonder if they can travel into the past and fix everything. and maybe its possible we can traveling through time.
i read some wise words from the forum. It says "if universe is infinity, then the possibility is infinity". so if time traveling is real, do you know what time you want to back? I know mine.
