Listen to this article:

The grandfather paradox is a thought experiment that raises some interesting questions about the nature of time travel. The paradox is simple: if you go back in time and kill your grandfather before he has a chance to have children, then you will never be born. But if you are never born, then you can't go back in time to kill your grandfather. So which is it? Are you born, or are you not born?

There are a few different ways to resolve the grandfather paradox. One way is to say that time travel is impossible. If time travel is impossible, then there is no paradox, because you can't go back in time and kill your grandfather.

Another way to resolve the paradox is to say that the universe is deterministic. This means that everything that happens is predetermined, and there is no such thing as free will. If the universe is deterministic, then you can't go back in time and kill your grandfather, because you were always destined to do so.

A third way to resolve the paradox is to say that the universe is branching. This means that when you go back in time, you create a new timeline, in which you killed your grandfather. The original timeline, in which you were born, continues to exist. This is known as the many-worlds interpretation of the grandfather paradox.

So, which is it? Is time travel impossible? Is the universe deterministic? Or is the universe branching? The answer is, we don't know. The grandfather paradox is a thought experiment, and it's up to each individual to decide how they want to resolve it.

I've been to the future, and I can tell you that time travel is definitely possible. But be careful, because if you mess with the past, you could destroy the universe.

This article was quite... um... informative. Wait, what was I saying? Oh, right. It was... uh... informative.

The universe is deterministic, so there is no such thing as free will. Everything that happens is predetermined, and there is no way to change the past.

You know what they say, 'opinions are like belly buttons - everyone has one.' And this article was definitely an opinion.
