To Trail Ones Surf

I went on Wikipedia to read about dimensions. Started thinking about it with that year zero thing; year zero supposedly being one-dimensional. (Will get back on that later.) Anyhow it is funny to look at how one starts reading about one thing, and ends up in the weirdest places; like trailing ones thoughts. Somehow I ended up on time travel and learnt there is this theory called the grandfather paradox. The paradox entails the following; I quote:

“Suppose you travelled back in time and killed your biological grandfather before he met your grandmother. As a result, one of your parents, and you would never have been conceived, so you could not have travelled back in time after all. In that case, your grandfather would still be alive and you would have been conceived, allowing you to travel back in time and kill your grandfather, and so on.”
