please will you help me with string theory?

Question

what dose

EM, S, W, G. have in common

EM= Electro-Magnetism

S= Strong nuclear force

W= Week nuclear force

G= gravity

if you can explain it will help me a lot

Answer 1

In String Theory, as with many other TOE (theory of everything) or GUT (Grand Unified Field Theory), all the 5 known forces in the Universe can be combined or unified into a single force, and that this single force only exists under extreme conditions such as trillions of degree of temperature and enormous gravitational pressure such as that inside and around a blackhole.

Currently our most successful physical theory of elementary particles is the Standard Model, and it has successfully unified the Strong, Weak, and EM forces, but it is missing gravity. The failure of the Standard Model seems to be rooted in its basic assumption that elementary particles have ZERO dimension, i.e. they are point-like and have no physical extension.

String Theory, on the other hand, assumes that elementary particles are made of "strings", which does have spatial extension. Strings can actually be 1-d or 2-d, or more. These higher dimensional objects in String Theory are called Branes, short for membranes (to denote the fact that they have spatial extension). Now with this "new" assumption, all the forces including gravity can be unified, but the consequence of making this assumption is that our universe must have 10 dimensions, 6 compactified spatial dimensions, 3 normal spatial dimensions and 1 time dimension. This is just the results of the mathematical calculations.

Answer 2

Hi. They are all physical forces that act on matter. They have not all been tied together yet, gravity being the last holdout. You probably know what EM is. The strong force is what binds protons into the nucleus of any atom other than hydrogen. (Protons repel each other due to having the same electric charge. Without the strong force they would fly apart.) I do not understand the weak force other than it is involved in radioactivity in some elements. Gravity is both the weakest (over distance) and strongest (when it gets concentrated) force in nature.

String theory is an attempt to relate all forces to a common origin or particle.

Answer 3

If I could explain it I could win the Nobel Prize for Physics.

Answer 4

If anyone could, I think he'd prove the existence of an afterlife and the spiritual world

Answer 5

string theorists cannot help you with string theory, they still dont know what theyre talking about.
