if you went back in time would you be able to kill your grandfather before your father was born?

So say you could do that and kill your grandfather, you'd have no father and you wouldn't exist. What a fantastic idea you have lemon!!!!!! 😉 😛

The laws of physics be damned...I would, and that’s what counts.

I've read that something would always prevent this from happening no matter how hard you tried

The question is moot, since no paradox would exist because according to the Theory of Relativity, going back in time is impossible. Sorry to burst your bubble.

the issue is not moot
according to wikipedia
time travel to the past is theoretically possible in certain general relativity spacetime geometries
I don't understand the physics of spacetime geometries but I don't think the final word on this issue has been said

In his final book Stephen Hawking said that travelling backwards in time was an interesting and serious question.
