Duality

I see! I read once that, if you could see far enough to see the limits of the universe itself, you would see the back of your own head, and if you could travel at a speed sufficient go beat the rate of expansion, you would never escape the universe but would eventually wind up right back where you started. Mind such a theory is a bunch of conjecture that requires us to manage to beat the rate of expansion (which is impossible with our current technology and inconceivable out to the distant future), but is that not true if you take away such assumptions?

Google Maps once told me I was in Alaska when I was in my home town which is nowhere near Alaska. 

Nobody knows for certain, but it doesn't look like it at the moment. That's another example of a 'looped dimension', which don't appear to occur in our universe (although this may just be because our instruments aren't precise enough to detect them).

Probably caused by a black hole created by CERN. Software is clearly infallible as we all know. 

I was about to ask if a wormhole would constitute a looped dimension, but from what I understand those may theoretically occur in black holes, which are “holes” in the universe, for lack of a better word. 

 I often wonder what it would be like to witness another dimension with my own eyes. Instead of conjecture or picturing it, seeing it myself. Were I to somehow leave the universe or go to another universe (assuming the multiverse theory is true), who is to say I could survive there even with a suit? What if the laws of physics are so out of it there I am killed immediately? 

 I tried jogging to the end of the universe just last week and only made it about halfway
