This topic is always interesting to me. Space must have an outside. Idk what, another dimension, another universe or parallel worlds. Idk.
The big bang can be considered equivalent to a dot on a peice of paper. With a line that represents time.! So a line is present ,past and future. So what the hell is the peice of paper???????? Furthermore, what the hell is the pencil?
although, this is not my master topic, i know for a fact that there is one equivocal truth about the universe. Everything moves!!! Planet moves, plants, peopleo, comets. Teutonic plates. Nothing is still. So whats in the background must move our universe. One big clockedit on 2-2-2014 by Jordan River because: (no reason given)
In theoretical physics, M-theory is an extension of string theory in which 11 dimensions of spacetime are identified as 7 higher-dimensions plus the 4 common dimensions (11D st = 7 hd + 4D). Proponents believe that the 11-dimensional theory unites all five 10 dimensional string theories (10D st = 6 hd + 4D) and supersedes them. Though a full description of the theory is not known, the low-entropy dynamics are known to be supergravity interacting with 2- and 5-dimensional membranes.
This idea is the unique supersymmetric theory in 11 dimensions (11D), with its low-entropy matter content and interactions fully determined, and can be obtained as the strong coupling limit of type IIA string theory because a new dimension of space emerges[clarification needed] as the coupling constant increases.
Drawing on the work of a number of string theorists (including Ashoke Sen, Chris Hull, Paul Townsend, Michael Duff and John Schwarz), Edward Witten of the Institute for Advanced Study suggested its existence at a conference at USC in 1995, and used M-theory to explain a number of previously observed dualities, initiating a flurry of new research in string theory called the second superstring revolution.
In the early 1990s, it was shown that the various superstring theories were related by dualities which allow the description of an object in one super string theory to be related to the description of a different object in another super string theory. These relationships imply that each of the super string theories is a different aspect of a single underlying theory, proposed by Witten, and named "M-theory".
Originally the letter M in M-theory was taken from membrane, a construct designed to generalize the strings of string theory. However, as Witten was more skeptical about membranes than his colleagues, he opted for "M-theory" rather than "Membrane theory". Witten has since stated that the different interpretations of the M can be a matter of taste for the user, such as magic, mystery, and mother theory.[1] In the TV adaptation of The Elegant Universe, Witten suggests the M as also meaning 'matrix', along with Leonard Susskind guessing it as meaning 'monstrous'.
M-theory (and string theory) has been criticized for lacking predictive power or being untestable. Further work continues to find mathematical constructs that join various surrounding theories. However, the tangible success of M-theory can be questioned, given its current incompleteness and limited predictive power.

M Theory is interesting, even in it's non predictability, perhaps that is the nature of the Universe beyond certain levels, or perhaps there is an equation, yet to be realised, that can tie up those loose ends and give more predictable results. I certainly believe that dimensions are imperative to understanding the complexities of the Universe and beyond.

String theory is kinda disappearing less and less physicists are exploring this i think its probably a dead end.See not only is it unprovable like you point out but they keep trying to patch it to explain things we know or learn. Its really starting to look like that quilt that has been in the family for generations with strings and patches hanging off everywhere. Its end started with the KKLT paper which indicated that string could not tell the difference between millions of alternative versions of physics. It was something along the lines of 10-500 alternative string vacua.The big thing means its not falsifiable and its not predictable both requirements for a valid theory.So IMHO string theory was a dead end and time to backtrack and look at other possibilities.
If anyone wants to look into it here is the paper.

Magnetic monopoles have not been created we have created simulations of them There’s more a mathematical analogy and cool one at that. But they're not magnetic monopoles. And m theory predicts their existence but so does many quantum theories so its not really proof of m theory.

I think the universe is a looped system. Once our telescopes can see far enough we will be able to see ourselves. Once this is understood it will throw a bunch of theories on the distance of objects in space into the recycle bin..

This kind of stuff goes way over my head but my brother used to say that there were two voids with rips in them, one filled with matter and one empty.
The matter would spew out into one side filling out the empty side reaching the point where it gets so fill it starts poring back into the side that had the matter which is now empty and it just cycles forever...

It's probably more darkness and void of any light.
