I think the old time travel paradox thinking is based on limited knowledge of the physics involved in and operating the Universe.
There's thinking that a paradox would not happen, as it would be impossible for it to happen in the first place (the grandfather paradox), instead
the thinking is leaning towards additional dimensions being created for each paradoxical event.
In the example you give, going back and killing your grandfather before your father was born, would mean you were never born in order to go back and
prevent your birth, hence the paradox right?
Well, you could go back and kill him and still be born as per the current timeline if another dimension was created when you travelled back. The
'time machine' is effectively not a time machine, but a dimensional travelling machine. Y
ou leave our dimension (with it's timeline) and enter another dimension, exactly the same as ours apart from the fact that it is a dimension that was
always going to have the early death of your grandfather and non birth of your father and all of his line (you). That way, you could quite merrily
kill the grandfather in the alternate dimesion, without causing a paradox in our dimension, where your grandfather (and his line) was always destined
to have lived.
There are probably infinite dimensions, encompassing infinite variations..we just travel to a different although very, very similar dimension to avoid
the paradox question.
