The difference between a lie algebra based on group E (8) (left) and the standard (right) model. The lies algebra that defines the standard model is mathematically an entity 12 dimensional; Group E (8) is fundamentally an entity of 248 dimensions. There are many things that have to disappear to recover the standard model of chain theories as we know them; With fewer parameters and less assumptions, our universe currently described is described much more simply by the standard model and general relativity than any other description.

When you do not have enough clues to close your detective history, you must expect your educated assumptions to be wrong.

Is all useless modern theoretical physics? If you listen to any of a number of Disillusioned physicists of high energy (either PHYSICAL ASPIRANTS), can conclude that it is. After all, the twentieth century was a century of theoretical triumphs: we could, both in subatomic and cosmic scales, to finally make sense of the universe that surrounded us and understood. We discovered what the fundamental forces and interactions that govern physics, what were the fundamental components of the subject, how they assembled to form the world we observe and inhabit, and how to predict what are the results of any experiment carried out with those how many.

Combined, the standard model of elementary particles and the standard cosmology model represent the culmination of the physics of the twentieth century. While experiments and observations have revealed a series of Hitherto unsolved puzzles – Puzzles such as dark matter, dark energy, cosmic inflation, barioogenesis, mass neutrinos, the strong problem of PC and many others, theorists have failed to progress significantly in all these issues during the past …
