paradox or not???

[gonzo4life44]

ok in the last topic i was a part of, we kinda talked about paradoxes. now ive herd two different types of paradoxes but they are totaly different from each other. now im not sure if a paradox has two different meanings but i know that for sure, one of them is a real paradox. ok, the paradox that every1 talks about is the one about the arrow hitting the target. it goes like this: lets say you throw an arrow at a target. in order to hit the target, the arrow must travel half the distance to hit. now if it cept traveling half the distance, the arrow will never hit the target.

To me, that is not a paradox. an example of a paradox to me would be something like this: lets say you go back in time to kill your grandpa. you kill him and you come back to present day alive. it cant be possible to live because in order you you to life, you grandfather had to of been alive because your dad needs to be born in order for you to be born. this affect causes a loop that is not possible.

ok so out of those two examples, which 1 is the paradox because they are two toatly different things. pls help me out with this 1 people.
