/////////////The Grandfather ParadoxThis is a very simple idea with serious repurcussions for the concept of time travel. Let's say that I invent a time machine and travel into the past. I meet my own grandfather when he was a boy and kill him.
The result? One of my parents is never born, therefore I can never be born.
So I couldn't have gone back in time and killed him.
This is a logical contradiction - and a philosophical nightmare!
