How the unified theory will be? Will it be so simple that any one can get it or too complex?

Question

We are looking forward for a unified theory. How it will be? Too complex mathematical interpretation so that no one can get it completely or so simple that is so close to nature so that a child can say this is the fact.

Answer 1

My view is that it will be a little difficult for most people to follow.

Much of the basic research (at FNAL and CERN) is done at very high energies that are attempting to illuminate structures and particles that may have existed in nature only for a brief moment after the Big Bang, if at all. After the Big Bang, things sort of "settled out" and, in a way, cooled off so that the fundamental relationships that exist between many things we see today are less obvious.

Even now, forces such as gravity and electromagnetism are understood at varying levels. Probably most people on the street have never heard of the strong or weak forces. So while it will feel good to have a unified theory, understanding it in a meaningful way will be limited to a few; applications and analogies will suffice for the rest.

Answer 2

It will be a Tensor. A tensor is sort of like a matrix only with n dimensions. A scalar with one row and column is a tensor with rank 0, a vector with 1 column and multiple rows has rank 1, a matrix with rows and columns but only 1 depth is rank 2, a matrix with depth rank 3, ect. This will map out a system of differential equations defined based on the basis defining your space. The TOE will almost certainly be unsolvable, requiring computers to generate differential equations and solving them numerically. It is possible however that under certain very ideal circumstances exact solutions to the TOE will exist, though the result of this solution will likely be a partial, non-linear, high order, unsolvable differential equations. However Einstein didn't believe any exact solutions to GR would ever be found, but there are more then a handful of exact solutions found to date.

So in conclusion the mathematics behind the solution will be difficult to grasp without a Ph.D. and, though on paper the equation may be as short as a sentence, solving it will almost certainly require many many pages of equations.

Fear not though. One of the surest tests of new theories is that they are backwards compatible, under normal circumstances, with previous equations. This means that on human scales it will ultimately reduce to such equations as F=ma, Gmm/r^2, and kqq/r^2.

Answer 3

The TOE will most like be simple per Occams Razor

Answer 4

How many people do you think actually UNDERSTAND E=mc^2? They may know what it stands for, but very few people really understand it. Do you think more will understand the Theory of Everything?
