and you had unlimited vision, would you see the back of yourself when you looked up ?

All recent research indicates that the geometry of the universe is "open," meaning that parallel lines never converge. For what you describe would require that the universe be "closed."
It's true that space-time is curved by the presence of mass, but these are local curvatures and not cosmic in extent.
Simply put, no you could never see your back.

No. What this means by curved space is, Gravity is curving the space around it. For example, the Sun. It has gravity right? Well, The gravity would curve the space around it and check this out..... there is a star behind the sun that you can see. How this occurs, Gravity is bending the space around it along with the light from that planet. Well, You can see that star behind the Sun because the gravitational field of the Sun is bending the light. So, that is what that means.

No it is not.
For the most part, light travels in a straight line from somewhere to here.
Now, recent discoveries have shown that some bending of light rays can occur as a result of space objects which have massive gravitational pull. However, once bent, the light rays continue on in a straight line from that point. They do not curve around and come back again, like in a circle.
The shape of space and its ultimate limits are undefined as of this time. There are many theories out there which suggest one thing and another. You are free to read up on all of them and pick which ever one seems to agree with your mental capacity the best. However, i do not think that there is anyone who can prove that their idea or theory is the only one that is correct at this point in time.
As far as seeing behind you in a curved space continium...
Well, I would hang that one out to dry also. how can you possibly bend something (curve it) which is 40 Billion Light Years wide in all directions from Earth? That is the current distance we can presently "see" out to with the most refined optical and radio telescope equipment available to man. That is not the "end" of space. That is just the fartherest we can "see" with our present technology equipment. Maybe in five or ten years we will be able to extend that to 60 billion Light Years distance in all directions. Who knows? However, we are certainly not looking out into a curve at all. There are lots of theories out there... This one I would give a hello to and keep right on trucking.

technically you can see yourself in the past or, some people say, in the future due to the curvature of space caused by gravity and how it also curves light.

Yes. But you will have to watch for it for 13 billion years, and have a REALLY big telescope.

There's an old saying, that "there's no such thing as a stupid question". You have just proven it to be wrong!
