Three Ways to destroy universe
An extension with a huge tear at the end ? Freezing death because of all the stars die and the universe become dark ? Or for finish the beautiful death of a global warming of the universe and the creation of a huge black hole. I let you choose what you prefer ! Personally I love the idea of the huge tear, but this is not the most popular in the physicists community. Wait I ust think about one thing, these theory can be possible in a very long time, we will be probably dead before all of that !
