Physics: Time: Travel: Back: Can you manipulate the future if you 
travel back in time? [paradox]

---

If you could somehow travel back in time, and comparing this
possibility with the possibilities seemingly present according to
quantum theory, it seems thus there is a constraint of the options
available to you.

---

You can only choose these options which will lead to that particular
state of your world in the future.

In other words, when traveling back in time, you can not manipulate
somehow the state of your world in the future, even if you wanted to.

Whatever you do, it will alter in or lead to that fixed future state.
