We say you have a machine that could go back and forth in time. The machine works roughly like this: A few seconds before you press the button to travel a week forth in time it will save like an autosave. Of course time will go on as if you had pushed the button which you had. You will disappear and that´s a part of the time. You could say you jumped off a branch and will jump back on it smaller distance in front of your first jump. The branch will be affected by the jump but not your time in the air. You just jumped a week forth in time and you decide to go back in time to the "Autosave" earlier! And here´s the question: Will you go back and forth in time forever or will this end circle end! This is a matter of how you are viewing universe and the time and i would like to hear some different comments about this, or comments if I´ve written something wrong and such. Just a discussion about it!
