Okay so my friend tells that once COULD go into the future, but when going to the past, wouldnt this create a wormhole (supported by Einstein's theory of relativity)? Does this mean there WAS a wormhole in 2001?
The Multiworldline theory goes like this: Whenever you time travel, you create a parallel universe. So, if you go back in time to kill your grandfather, you will only kill the one in that time line, not your "home" one. Also, there would be a duplicate of yourself there and you would be missing from your "home" timeline. The thing is, Titor mentioned many times that he COULD return to his original, home timeline. I like to call this zero divergence. Of course, he never specified if he had a copy of himself there or not and if it truly was at zero divergence. Here are some quotes. (I'd give you the link, but I no longer support the author that posted this). This seems to have been a question/answer session and he edited out all the extra info.
Are you able to return to your home?
Yes.
Do people know where you are? Can you communicate with your home?
No. They do not know where I am and I cannot communicate with them. Interesting idea though. From their point of view, I will return almost exactly at the same moment I left. From their viewpoint, I will only have aged more than expected.
If this worldline is 2 percent divergent from your worldline, how do you get home? If you go forward from here to 2036, won’t the divergence approach infinity?
Yes, this is true. If I go forward on this worldline, the future will not be my future. I get home by going back to 1975 before I arrived and then going forward to 2036.
If I go forward on this worldline, the future will not be my future. I get home by going back to 1975 before I arrived and then going forward to 2036.
A few people have asked me about this statement so I will try to clarify it.
On my worldline: (A) in 2036, I was given a mission in 1975. I turn my machine on and jump to another worldline (B) in 1975 with about a 2% divergence from (A).
From the very point I turn my machine off on (B), I create a new worldline just because I’m there. This line can be described as © and started when I got to (B).
I am now doing my mission on line © in 1975 when I discover a very a good reason to go forward on © and see what happened. I turn my machine on and go forward on © to the year 2000.
When I turn it off, I start another line called (D). So from my perspective, here we are on line (D) in the year 2000. In order to go home to line (A) I must turn my machine on and go back on (D) until I reach © which in turn would take me back to (B) which in turn takes me to a point before I arrived on (B) then I go forward from the point I arrived on (B) back to (A).
If all this isn’t enough to get your head spinning…here are some issues we’re dealing with in 2036.

Thank you for considering the problem of (my) returning home. You seem to have stumbled on an intuitive proof of some of the physics of time travel. You are correct, getting back to the worldline of origin is easier than picking an exact destination on a different worldline.
I wrote down the graphic you outlined. If y1 starts perpendicular to x1 and x2 and is rotated, where is the center of rotation? I imagined it between x1 and x2. If this is so, wouldn’t y1 end up parallel between x1 and x2 with each one being 6 inches away from y1 on either side?
