On November 21, 2009, I went to see a play called Einstein’s Dream. In this play, this main character just finished his work on “special theory of relativity,” and every night, he is dreaming about all the different places of the world with different time. What I mean by different time is, time operates differently: Sometimes, it goes backward, sometimes there is no time, only stopped moments, and sometimes people go through same time periods indefinitely but experiences other things. This play was little bit too complicated but can be very interesting play for people, especially the ones who know the theory of relativity.
