I like to do things with a geometrical way rather than just flooding yourself with equations. So if i can see a picture, that makes a lot more sense to me. Here we have the universe as moless if i had it before. Now i'm going to do two tricks. One of them is the trick which i've playing around with a lot to begin with.
