Talk of Free Will

I find very interesting the mentioning of free will in this chapter. When Billy begins to travel through time, jumping from one moment to another and asks why he is there, a voice tells him that he is there because time is fixed that way; the moment is fixed and cannot change. This comes to my attention because the sense of time travel has always seemed to me as a method of going back and fixing what we thought we did wrong or could have done better. I believe this connects to the notion of free will because it is that sense of freedom we human beings have that trigger all of these hopes for changing the way things are or the way we have made them. In reality, there are some things we can change, others we cannot. Time is one of those we do not have the power to change or control and this is what I believe the Tralfamadorians mean when they say that only on Earth is there talk of free will. Free will does in fact very little in the real world.
