What Theories Exist About the Edge of the Universe?

[Quiksilver421]

Alright, so, I'm sorry but I posted this back when I was getting my CS degree and have been looking back on my previously asked questions. Sooo, here goes a two year old question that I think time may have changed the results of.I've been mauling some questions about the end/edge of our universe in my head over the last couple hours, and Google is soooo inundated with useless pages. So I figured I'd come here to get some theories.
Sorry if I ask any dumb questions or posted this in the wrong thread. To Mod- I will move & delete if possible.

I understand that any information on this topic is speculative and I welcome all answers.
No answer is a bad answer. If you know of several different theories for one question, please include them.

*It= The edge/end of the universe. **Edge just symbolizes the farthest part of our universe, like I'm there touching it (To clarify)

1.Is it a boundary (cross if you dare type deal)?
1a.Or is it a wall?

2.Is it hot?
2a.Cold?
2b.Or neither?

3.Could I touch it (if I was at the wall)?
3a.What would it feel like?
3b.Would it be the smoothest object ever?

4.Is the inner wall positively charged (to push it further out), with the outer side being negatively charged (to pull it further out)?
4a.Vice versa?
4b.Or neither?

5.Would it have a definable color?
5a.If so, would it be the purest/deepest black (for examples sake) possible?

6.Could matter even touch it (since it was the first one out of the gate)?
6a.If matter could touch/interact with it, would the energy be absorbed and redistributed along the edges of the universe like a wave rippling out along the wall from one end to the other indefinitely until the energy acquired at impact slowly "leached" back into the universe (negative A's impact energy flowing along the universes wall to negative Z, and positive A's impact energy flowing along the universes wall to positive Z)?
6b.Or, would the impact energy be reflected back into the universe relative to it's angle of impact?

7.Would the outside of the universe resemble a solid wall of matter (infinite in size) that has yet to be given a value; since the universe hasn't expanded to encompass that space yet (For example- a hard drive with one folder written onto it, leaving the "blank/nil-valued" space there with one sole purpose, to handle the inevitability of new data)?
7a.Or is the universes size constant?

And my most crazy question,

8.Could the end/edge be a giant spherical data interpretation medium, with the inside and outside layers creating a medium capable of reading and/or recording data?
^^ ^^ ^^ ^^
Here's a link to PopSci where a new method of data recording uses heat instead of magnetic fields.

Sorry for any poor sentence structure in my post, I despise commas and periods

Thanks for taking a look

Live it, Learn it, Love it, Do it, Master it, Say BOO-YAH!

There is no edge to the universe, in any of the senses that you mean. The universe is either infinite or finite but unbounded. Either way, no edge, so your questions have no meaning in physics. That has not changed in the last 14 billion years and isn't going to change in the next 14.

 

[Chronos]

The 'edge' of the universe is an illusion created by the finite speed of light. If you could travel to the apparent 'current' location of the CMB instantaneously, the CMB will have receded an additional 13.7 billion years [the travel time of the light you observed before departing] upon your arrival.

Several posts have been deleted in some thread cleanup. One was factually wrong, and several were correcting the mistake, but it became apparent that the OP was becoming confused by the factually wrong post.

*It= The edge/end of the universe.

As was already mentioned, there is (in modern cosmology) no edge of the universe. There are several FAQ's that are relevant to this topic:

Because there is no edge of the universe, the remainder of your questions are essentially unanswerable. I would recommend that you read a few of the relevant FAQ's and then come back and post some specific questions. I am temporarily closing the thread until you have a chance to do so. PM me when you have some specific questions after reading some of the FAQ's.
