Being a serious fan of time travel fiction, I’ve often thought about issues like this.
And then you have Doctor Who, where you take all three theories of time travel, stick them in a blender and press the button for 30 seconds. Then you dump it out, smash the remaining bits with a hammer and rearrange them into some semblance of order and have them all governed by a mad man with a box.
