Will A Theory of Everything (TOE) Put an End to Physics?

Can humans ever achieve a theory which will put an end to physics or approach an equation explaining the ultimate physics? These are some of the questions for which the scientists are looking for the answer.

One might think that achieving a theory of everything (often called “ultimate physics theory”) is just the beginning of the so-called Physics that we study nowadays. Physicists believe that a theory of everything will tie together all the basics of physics. And it will describe the behavior of particle and the details of how space and time behave in certain cases.



Researchers have observed that previous unifying theories (not the unifying theory) don’t generally explain problems on their own, but they somehow provide tools to elaborate the answer to certain questions later on down the journey. For example; Sir Isaac Newton unified “the apple pulling force” (gravity) with the planetary revolving force (orbital gravity) under the shed of “universal gravitation.”

With universal gravitation, on our sides, we can explain why Earth goes around the Sun. Also, why all orbits and even orbitals in an atom are elliptical. Moreover, it can explain why planets, stars, moons and even Earth are round. This is what we can’t explain without a huge contribution of Math. What we can’t explain without Math are things like phase lock, Lagrange points and why some galaxies out there have spring type (spiral) arms.

We can actually explain or elaborate that how two objects will revolve and spin around each other. But as soon as there are three of them to talk about, the best you can do is giving hypothesis. This is what scientists call “three body problem”. And many expect it to remain unsolvable forever. A certain example for such case is the Trojan asteroids around Jupiter’s Lagrange points in pairs of twos.

However, a theory of everything is estimated to be able to describe the how forces, particles, and galaxies interact on certain and possibly all levels. Amazingly, it would still be only a set of equations. But the reality is quite different. This equation might not explain the things that we want it to explain. Probably, the scientists desire to find it under their own terms. This is believed that theory of everything will not put an end to physics as this equation cannot explain parts of physics like thermodynamics etc.

Ultimate Physics

Building a quantum hypothesis of gravity has been the remarkable issue in hypothetical material science throughout the previous 30 years. It is a whole lot more troublesome than the quantum speculations of the solid and electro-frail powers. These engender in a settled foundation of space and time. One can characterize the wave capacity and utilize the Schrodinger wave equation to develop it in time. Yet, as indicated by general relativity, gravity is space and time. So in what manner can the wave work for gravity advance in time? Also, in any case, what does one mean by the wave work for gravity? Incidentally, in a formal sense, one can characterize a wave work and a Schrodinger like condition for gravity. But in anyway, they are of little use in genuine figuring.



In the years since 1985, we have understood that both super-gravity and string hypothesis have a place with a bigger structure, known as M hypothesis. M hypothesis isn’t a hypothesis in the standard sense. Or maybe it is a gathering of hypotheses that look altogether different yet which portray the same physical circumstance.

These speculations are connected by mappings or correspondences called dualities (duality plural). These dualities suggest that they are on the whole impressions of the same hidden hypothesis. Every hypothesis in the gathering functions admirably in the point of confinement, similar to low vitality, or low dilation, in which its viable coupling is little, yet separates when the coupling is substantial. This implies none of the speculations can foresee the eventual fate of the universe to discretionary precision. For that, one would require a solitary plan of M-hypothesis that would work in all circumstances.

“Einstein spent quite a bit of his life endeavoring to discover such a hypothesis.”

Never a devotee of the haphazardness of quantum mechanics, he needed to make a hypothesis that would unite gravity and whatever is left of material science, with all the quantum strangeness as an auxiliary result. He spent near about 30 years of his life for this fruitless research.

He died in 1955, his ultimate physics theory or theory of everything still not discovered. But in the same decade, the strongest candidate for a theory of everything came out as the string theory.



Stephan Hawking’s Comments

Stephan Hawking comments by stating that up to now, most scientist and people have believed that there might be an ultimate physics theory which might end physics. He adds that I also once believed and suggested that we may find it very soon. But in reality, M-Theory has made me wonder whether it is possible or not? Maybe it is not possible to make up a theory describing the universe in a finite number of statements or equations.

Godel’s Theorem:

Gödel’s incompleteness theorems include theorems of mathematical logic which show the inherent limitations of every formal axiomatic system containing basic arithmetic. These results published by Kurt Gödel in 1931, are important for both mathematical logic and philosophy of mathematics.

But

Assume someone comes out successful in this quest. This will not put an end to the Physics as this equation will not be able to describe thermodynamics, three body problem etc. Hence, the dream of ultimate physics is keeping the Physicists in their business of research and development further on.
