Taking the cue from chewyx’s blog here’s my take on M-Theory’s visualization aspects.

What our universe looks like. Bubbles.
So, what’s all this crap about?
In the standard model of the universe, physicist proposed that matter was made up of lots of tiny invisible atomic particles and their interaction is explainable by the Theory of Relativity (The very big) and Quantum Theory (the very small). The theories were however inconsistent and thus physicist were convinced that there had to be a unifying theory that could resolve these inconsistencies and therefore explain everything about the universe hence the aptly named Theory Of Everything.
So have they found this Theory of Everything?
The strongest contender so far as of now seems to be String Theory, which came along in the 1980s, and it says that particles are made up of really tiny strings. The different ways in which the string wiggles represent the different kinds of elementary particles. It’s like a guitar string, and it can vibrate just like guitar strings can vibrate. Each note if, you will, describes a different particle. The strings vibrate and how they vibrate determine what kind of particles they form. If you were to vibrate them this way, you’ll get a proton and if you vibrate them another way, you’d get and electron and so forth. With the inclusion of supersymmetry String Theory became Superstring Theory. A fundamental idea to Superstring Theory is that reality is composed of ten dimensions.
So now our universe is an orchestra? Great, hope they’re playing something good though but ten dimension? Now you’re yanking my chain here
Well yes, the three (normal) spatial dimensions, plus one for time and another six tiny spatial dimensions. Hence whereas matter might consist of ten dimensional strings, the string would only appear to us in our four dimensions as a particle. The problem of Superstring/String theory so far is when physicists struggled to explain all the weird shit in the universe they somehow ended up with five different theories, which is rather problematic for a possible Theory of Everything.
Wait a doggone second! The TOE is actually 5 Theories?
Yeap, Enstine did say that the equation should be an inch or so in length, but if you think 10 dimensions is bad then you’re gonna love what’s coming up next. The next problem with String Theory is it’s failure to explain as the Big Bang (the birth of the universe) which is basically a singularity at some far distance past. This is because that’s when all the equations stopped working.
Before Superstring theory came along though, there was a theory called Supergravity which was then, where Superstring theory is now, a real good contender for TOE, but being ousted by Superstring theory, it became unfashionable got ignored. Supergravity had always been convinced there were exactly eleven dimensions but by now the boot was on the other foot and String Theory was in shitload of trouble. Its’ five different versions meant it couldn’t be the all-embracing theory physics was looking for. Everything, it seemed, had been tried to save String Theory. Well, almost everything. In a final desperate move the string theorists tried adding one last thing to their cherished idea. They added the very thing they had spent a decade rubbishing: the eleventh dimension. Now something almost magical happened to the five competing String Theories when the 11th dimension was added to the equations of the five String Theories. The answer turned out to be it turns out that they were all the same.
Hence was born M Theory (M for Madness, Magnificent, Magical, Membrane), with the central amazing postulate, that our entire universe is a membrane; one single vast structure to which all the matter in the universe is connected.
Wow, that’s pretty neat, now I that’s a killer topic for picking up chicks!
That’s just the tip of the iceberg, next comes the weird stuff from Star Trek. Some physicist were discussing M Theory and the origin of the universe and came up with this question: “What would happen if there was more than one membrane? What happens if they collide?” The result, one Big Bang - literally. No more singularity, no more broken equations. We have a possible explanation of how it all began otherwise known as the ekpyrotic universe.
What? More than one universe? Now you’re saying that the sci-fi parallel universe concept is a reality?
Yeap, welcome to the multiverse, where our universe co-exists with other membranes, other universes. In fact there could be an infinite number of membrane-universes, each with a utterly different law of physics. Big Bangs would be happening all the time.
If there is an infinite number of universes, then there will be an infinite number of occasions in which two membranes have collided to create a Big Bang exactly like the one that created our universe, with exactly the same physical laws, with exactly the same sequence of events since the moment of creation. Except that, in one of them Germany won WW2, in another you actually got the guts to ask that hot chick at the bar for her number and in yet another you were never born. Every possible outcome that you can imagine will and has occurred and will happen again. And again. Infinity is a very big number.
Multiple universes also provide a possible explanation of why gravity is such a weak force in our universe. Yes I know, gravity seemed strong enough that time you fell off your chair after leaning back too much – but if it were so strong how come a magnet can pick up a set of keys or you being able to lift up a pair of dumbbells? Thus it is considered weak compared to other forces. The simple answer is that there is no gravity in our universe as such, what we have is gravity leaking in from an adjacent membrane-universe. Similarly there may be no need dark matter after all, to explain all anything
Of course all this is theory. It’s a difficult thing proving the existence of eleven dimensional structures when your perceptions are limited to only four. If the concepts produce pretty equations with nice elegant solutions everybody’s happy, as most physicists tend to think that there ought to be a nice elegant solution to the ultimate question. Therefore , God doesn’t play dice with the universe, he plays pool.

Oh yeah! One more thing one. Physicist Alan Guth believes it may well be possible to create a membrane-universe in the labaratory and therefore effectively creating a universe. This could mean that Alan Guth thinks he can become God. Wonder if the beings in this new universe will think he’s omnipotent, omniscience and omnibenovelent?
And you really understand all this stuff?
Well, not exactly. I still have several episodes of Star Trek to watch.
