Not really a new idea, but there it is.

Some of the smartest people are just plain retarded.

I found that very interesting.

So wait, what EXACTLY is holding you back from killing your father in the past? Just your conscience? Or is a physical bubble around you preventing you from committing thoughtcrime?

Or is your father physically going to be made of rubber.

I'm not buying this theory.

[Canyarion]

Yeah it's bull****.

Why don't they just accept it that IF it is possible to travel 'through time', you can only watch what happened earlier, not take part of it.

actually, what they're saying is that since in the present your father is alive, then you can't change that because the present has allready happened in the past many times. and no matter how many times you travel to point A in time it will always be the same because that's how it's always been. i actually understand what they're talking about, and it's not that something is stopping you from doing it, it's just it's imposible to re-write the past, so to speak. i wish i could explain it in more detail or in a more understandable manner, but without and diagrams i can't, and i'm just too lazy to draw anything in paint and post it.

[Canyarion]

I understand it as well, and explained it in my way.
