Grandfather Paradox

Steven Gibbs talks about the Grandfather Paradox using an HDR even. Basically, we know this is invoked in time travel movies. For example, they do talk about the Grandfather Paradox in the old Doctor Who TV series. Yeah, it goes this way. If a person were to time travel to the past, they could prevent their grandfather from marrying. Which means they were never BORN and they did not go back to the past to change events any. Certainly, this story sounds recursive. The solution is that we split the timeline into two pieces. OK, so on the original you were born, and on the second, you never were.
