Slaughter House-Five (chapter 4)

The moment simply is...

At this moment, the notion of time has been completely destroyed. Originally, I thought that the objective of these time-travels was to return to the present(or the latest event you experienced)with more knowledge.

There are two things that go against this, first of all, because Billy Pilgrim already died, as the author expressed in the beginning of the second chapter. Second of all, because this time travels wont stop.

Probably, Billy will finally learn to appreciate the present all the time. The theory proposed by the Tralfamadorians is that there is no thing such as cause and effect. It is always the present. The past and the future become the present since there is nothing that made you be here (at the moment) and whatever you do will always end with you being stuck in a different present, totally unrelated to your previous actions.
(I am talking about everything after his experience with the Tralfamadorians, not before.)

There are many questions left unanswered, like for instance, doesn't this mean that you are immortal? that you are stuck forever in a present that has no consequences? Again, the only thing left to do is living the moment.
