Exactly. When people ask the most ridiculous question "If you could go back in time would you kill Hitler?" there are so many things that don't make sense.

First, I don't have a time machine, I'm not in the process of learning how to build a time machine, and if there is a time machine out there I'm confused as to why the people who have it would randomly choose me to go back in time.

If I were suddenly swept back in time due to a glitch in the time space continuum would I not only go back in time but would I also travel great distances or would I simply go back in time but remain in the same location? If I went back in time but stayed where I am I would then need to travel to Germany. I don't have an ID or any form of currency from the 30s/40s so how would I obtain an airplane ticket? The clothes I am wearing today would look strange to them and my chances of getting a job would be slim, Chances are I'd be homeless and end up pan handling. If I obtained a guitar I could play some Beatles songs but they might be ready for that sort of thing.

If I made enough to buy a suit and an airplane ticket to Munich I still don't speak the language and my ability to find Hitler and get close enough to kill him would be nearly impossible. I would have to get to him before his rise to power but I remember very little of his life off of the top of my head and it's not like there would be books about him and the internet wouldn't work very well.

So let's say I found Hitler and killed him I would go to prison for killing an innocent art student and not one person on the planet would see me as a hero.

Despite all of this going back in time would have to include going through space because the solar system is moving like this.
