Time travel paradox, the person can travel in time but not change the past

The question about the time travel paradoxes is how big a part of the entirety we want to change? What if we travel in time backward and shoot some bloody dictator, what would happen then? The fact is that we don't know. 

The time loop is the case, where we are meeting younger us in the past, and then we are facing the question, what if we accidentally kill the younger us? Or what happens if we are accidentally killing our grandfather or grandmother during our time trip. There is a really interesting model, that we are thinking about as the cyclic time concept. 

So what is the cyclic time? The theory about the cyclic time is simple, even if we are making something in the past, that thing cannot affect things, what is already happening. The cyclic time means that the time is linear, but not congruent entirety. And if something is changed in the past that change would affect only the next cycle of the time.

The fact is that there are some philosophical thoughts about the case, where the time traveler would accidentally kill the person's grandparents. 

1) Time traveler would disappear immediately because that ever born

2) Time traveler could live normally, because the time is cyclic, and another cycle would start to travel after the death of the younger version of that person. 

3) Time traveler would live normally because that person is adopted, and the persons, who we kill are not the time traveler's biological parents

4) Time traveler would live normally because time travelers' grandmother is already pregnant. 

5)Time traveler would live normally because grandmother cheated the grandfather and that grandfather is not the time travelers' real grandfather.
