where is the beginning and ending of the world?

Isn't that like asking where is the beginning and ending of a circle?

The beginning is W, the end is D.

It depends on how you want to look at it. Scientifically the beginning was when many protoplants all came together to form all the plants that now exist in our solar system, granted that statement is a simplistic understatement to all the things that took place during creation. And the end is in question, but it will probably be when our sun goes red giant and it expands enormously and gobbles us up. Now looking at it from a religious point of view, which the two views could coincide if you look at them in the right light, Alpha and Omega. God created it and before long he'll come back and take us all away either to heaven or hell. Depends on how you look at it I guess.

It depends what is in the palm of your hands. If it is a gun it is the end, if it is a beautiful mate it is the beginning.

there is no beginning or end...its all just one conscience sense of being

At the start line and the finish line?

I would really love to tell you, but I'm not going to.
