There are many philosophies on that.
What i think of that is that the uneverse was always there and just was there. The purpose that the unerverse is there just to be there. I don't know why it is there. I just don't know and my opinion is that it has only been there. To disrupt the unerverse it world be hard. The unervse just would not have to be there to disrupt it that is my opinion.
