I read about this in New Scientist a while back... heavy going when you're coming down on a flight let me tell you.

its actually 11 now. M-theory FTW.

[parson]

10 + time

[snypadub]

its actually 11 now. M-theory FTW.

Was going to say this! didn't M theory unify all five string theroies???

[parson]

m theory makes an attempt to explain gravity

[parson]

m theory supposes that gravity exists as a curve that exists only partially within our perceivable dimensions and that if we could truly perceive reality, we'd see that gravity exists mostly extradimensionally, which explains why it appears so weak to us since the majority of it's force is on a curve that we can't imagine.

and y'all think I'M nuts.

[dreamizm]

Doesnt it also suppose that gravatons (particles of gravity) cam move between dimensions and would allow us to communiticate in other dimensions?

[hayze99]

I remember the good old days when there was only one dimension!

EDIT: three

[snypadub]

Atoms are multidimensional and exist across several (infinite?) universes meaning that we, in theory, do also!

We will, unfortunately, never experience the upper dimensions but we can see their "shadows".
I don't know how many dimensional shadows we can see up to, so far (geometrically speaking) we can definately see the 4th dimensions shadow.

I never once thought you where crazy Parson, some of your ideas (to me) seem a little far fetched. Then again a lot of what you say makes an incredible ammount of sense.

I believe in the theory of power in this planet and how there are very few select people at the top but I don't know if I want to tie this to the theories of illuminati and masonry!

Wow, talk about digression!

someone showed this to me the other week. extremely nuts.

[lloydnoise]

its all about E8 theory. Much simpler, not impossible to prove, a far more elgant model of the hows and whys. Also manifests itself (the structural symmnetry anyway) in reality (ST's downfall is it's going to be really hard to prove). The bluprint of the forces in our universe should be simple not savagly complicated mathmatics made up by the theorists themselves to make everything fit. I used to love reading about ST but it's all gone a bit silly and complex.
plus E8 was thought up by a surfer so its coool maaaan.

Consider a wavy, two-dimensional surface, with many different spheres glued to the surface—one sphere at each surface point, and each sphere attached by one point. This geometric construction is a fiber bundle, with the spheres as the "fibers," and the wavy surface as the "base." A sphere can be rotated in three different ways: around the x-axis, the y-axis, or around the z-axis. Each of these rotations corresponds to a symmetry of the sphere. The fiber bundle connection is a field describing how spheres at nearby surface points are related, in terms of these three different rotations. The geometry of the fiber bundle is described by the curvature of this connection. In the corresponding quantum field theory, there is a particle associated with each of these three symmetries, and these particles can interact according to the geometry of a sphere.
A projection of the 421 polytope, representing the structure of Wilhelm Killing's E8 Lie group.

In Lisi's model, the base is a four-dimensional surface—our spacetime—and the fiber is the E8 Lie group, a complicated 248 dimensional shape, which some mathematicians consider to be the most beautiful shape in mathematics.[8] In this theory, each of the 248 symmetries of E8 corresponds to a different elementary particle, which can interact according to the geometry of E8. As Lisi describes it: "The principal bundle connection and its curvature describe how the E8 manifold twists and turns over spacetime, reproducing all known fields and dynamics through pure geometry."[1]

The complicated geometry of the E8 Lie group is described graphically using group representation theory. Using this mathematical description, each symmetry of a group—and so each kind of elementary particle—can be associated with a point in a diagram. The coordinates of these points are the quantum numbers—the charges—of elementary particles, which are conserved in interactions. Such a diagram sits in a flat, Euclidean space of some dimension, forming a polytope, such as the 421 polytope in eight-dimensional space.

In order to form a theory of everything, Lisi's model must eventually predict the exact number of fundamental particles, all of their properties, masses, forces between them, the nature of spacetime, and the cosmological constant. Much of this work is still in the conceptual stage—in particular, quantization and predictions of particle masses have not been done. And Lisi himself acknowledges it as a work-in-progress: "The theory is very young, and still in development."

Actually looks really interesting!

this is all very interesting but tbh i don't give a fuck about the other dimensions.

That sounds like a pretty elegant description. Not heard of this particular theory before, must go looking.

It got a lot of publicity a few years ago... well, lots of tiny "In other news..." articles with headlines like "SURFER SOLVES RIDDLE OF UNIVERSE" anyway.

There's been some pretty bitter squabbling between supporters of him and those of String theory and he's never offered it up for proper peer review, I don't think... it's certainly elegant reading, but you think something must be holding him back - though I would think this is the sort of thing that's difficult to prove correct at the moment anyway, certainly until we've gained a lot more observation?

I remember seeing this video aged 13 and not having a fucking clue about what is was talking about.
I'd like to learn more about different theories and especially about String Theory...
