For the time machine question I forgot to bold the two relevent sentences.
I should had reworded my second question to "would timeline changes affect other time travelers?"
In addition how would the paradox proofing only personal in effect? What'ts the difference between ordering someone to grandfather paradox you (assuming you are in the time machine) and pulling the trigger yourself?
Okay. As for that, what I mean is that there was previously a time machine that arrived from the past, one that we did not create. It could not travel back in time, though, and the driver did not survive the journey. There was only ever the one, so we don't know exactly what happened or why they stopped after the first try.
By having someone else kill your grandfather like in your example, it is true the person in question would cease to exist. However, with the person traveling back in time to kill him having his existence cemented in that time, it doesn't matter if the person who asked him to do it no longer exists. They are separated as far as the known laws of space-time are concerned.
