If You Could Have 1 Superpower or Ability What Would It Be.

But the memory of that bad milk still remains in your mind right? Because if it doesn't then you'd never have a reason to change your past to not drink that milk. You'd still have to be aware of the outcome for this ability to work.

Time is a hard thing to establish in superpowers, I like to stick to the 2 main types, 1 is time travel on a linear path where no matter what you do or what you try and change everything is already set out and you going back in time to kill your grandfather won't work as you exist anyway, bit depressing if you think about it as it means everything in your life is set and you cannot change it. 

Another version is that by traveling back in time to allow for free will, you also jump one reality, you will be able to kill your grandfather but it won't affect you as a person, in the other reality you'd still travel back as planned. If you travel forward in this reality you'd travel forward in this timeline and not go back to the other.

Both theories make it so the 'grandfather paradox' cannot occur.

 

 

The problem with the second version is that you'll end up creating a never-ending stream of alternate realities since every time you went back or forth in time, altering the current event of that reality, you end up creating new alternate realities. 

Imagine that you start with one normal reality, you go back in time and undo an event from the past creating a new reality on top of the current existing one. Now, in both realities you still have the power to travel time and you continue to use it, creating new realities on top of the realities already created.

That would create a geometrical amount of realities being placed on top of one another with just minute variations between each other. It's a whole paradox in itself.

True but that's in the thinking above, you'd have to consider the fact that there already exist an infinite amount of realities to begin with. But you cannot use your power of time travel in a reality that you are no longer present. My basis for these thinkings is Marvel Universe's version of time travel (although confused at times to fit the stories), their main thinking is a 3rd version (like the second just extended to forward travel as well), when a time travelers jumps they step one reality as well as travel in time, the virgin reality which they left and the other where they arrived. It is defined as impossible to time travel in a virgin reality from the virgin reality.

In Marvel's case there is much confusion as time travelers seem to go to and from the 616 at will so it seems, but with every jump is means that they are stepping out of a reality (virgin) so they cannot affect it. 616 seems to be an essential 'top of the pile' reality, as we always see the present of that timeline. So as example, Cyclops and Jean Grey's time in the future (Askani) came to and end and they returned to the present 616, this is explained by them leaving 616 and entering Earth-4935. So they jumped one reality, a predefined one but still jumped it, when they returned the virgin reality is 4935 so they jumped back to the 616.

This definition might sort the idea of creating multiple endless realities, the idea that you don't essentially create them, you jsut travel in time between already exsting realities.
