INTRODUCTION: theory of everything physics
A theory of everything (TOE), final theory, ultimate theory, unified field theory or master theory is a hypothetical, singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all aspects of the universe. Finding a theory of everything is one of the major unsolved problems in physics. String theory and M-theory have been proposed as theories of everything.
HISTORY: theory of everything albert einstein
Over the past few centuries, two theoretical frameworks have been developed that, together, most closely resemble a theory of everything. These two theories upon which all modern physics rests are general relativity and quantum mechanics. General relativity is a theoretical framework that only focuses on gravity for understanding the universe in regions of both large scale and high mass: planets, stars, galaxies, clusters.
QUANTUM MECHANICS: Theory Of Everything Physics
On the other hand, quantum mechanics is a theoretical framework that only focuses on the three non-gravitational forces for understanding the universe in regions of both very small scale and low mass: subatomic particles, atoms, molecules, etc. Quantum mechanics successfully implemented the Standard Model that describes the three non-gravitational forces: strong nuclear, weak nuclear, and electromagnetic force – as well as all observed elementary particles.
GRAVITY VERSUS QUANTUM FIELD: Theory Of Everything Physics
The Standard Model of particle physics is the foundation of quantum mechanics that describes the world of atoms and their constituent particles such as the quarks and gluons, that make up protons and neutrons in atomic nuclei and electrons that orbit them.
The Standard Model explains three of four fundamental forces that govern the natural world: the electromagnetic force that holds atoms and molecules together through the interaction of their electrically charged components, the strong nuclear force which binds elementary particles called quarks into more complex protons, neutrons and electrons (and subsequently into atoms), and the weak nuclear force responsible for radioactive decay.
KALUZA-KLEIN THEORY AND THE BIRTH OF A MULTI-DIMENSIONAL UNIVERSE: Theory Of Everything Physics
HISTORY: KALUZA-KLEIN THEORY
Even before Albert Einstein turned his famed brain to the Theory of Everything, his contemporaries Theodor Kaluza and Oskar Klein attempted to marry his theory of general relativity with James Clerk Maxwell’s theory of electromagnetism, which in the late 19th century had provided an overarching explanation for the two main forces known at that time: magnetism and the electrical force.
To make their theory work, Kaluza and Klein had to invent a world that looked very different from what we see around us. They had to add a fifth dimension to our three-dimensional space plus time. This fifth dimension, however, was curled up and microscopic, a tiny loop that we cannot see on the level of everyday life.
STRING THEORY AND THE MULTIVERSE: Theory Of Everything Physics
INTRODUCTION: STRING THEORY
Theory Of Everything Physics-The first big breakthrough since Kaluza and Klein’s 1920s theory came in the 1980s in the form of String Theory. At that time, physicists, desperate to get rid of the infuriating infinite values produced by the theoretical colliding graviton particles (mentioned by Duff), proposed that elementary particles of the microcosmos perhaps weren’t simple points in space but instead tiny loops of strings, which only appear pointlike to us.
“It looked for a moment maybe as though this was the answer to all our prayers,” Duff said. “But soon we found that there were other problems.”
HIGHER DIMENSIONS: STRING THEORY
Theory Of Everything Physics-Just like Kaluza-Klein Theory, String Theory didn’t work in the ordinary four-dimensional universe. But it didn’t work in Kaluza and Klein’s five dimensions either. A universe of 10 and ultimately 11 dimensions emerged on physicists’ blackboards, where not just one but six to seven dimensions had to be curled up in the invisible realm for the theory to work.
So far, so good. The problem is that the way a string vibrates depends on how it’s wrapped up. When mathematicians tried to calculate the number of possibilities of this wrapping-up, they arrived at astounding values.
SUPERSYMMETRY AND SUPERGRAVITY: STRING THEORY
Theory Of Everything Physics-To make the String Theory equations work, physicists had to reconcile the behaviors of two types of particles: bosons and fermions. Quarks, the building blocks of protons and neutrons, are fermions as are electrons. This means fermions are the fundamental constituents of matter. Bosons, like photons, gluons, and W and Z bosons, on the other hand, carry the forces that hold this matter together.
Both of these types of particles are characterized by their spin, which is the amount of angular momentum a particle possesses and determines which way it will travel when exposed to a magnetic field. The spin values of fermions and bosons can also exist in discrete amounts and spin is conserved for all particles, but these values are very different for these families of particles..
M THEORY: STRING THEORY
INTRODUCTION: M THEORY
Theory Of Everything Physics-Throughout the 1980s and 1990s, competing approaches were developing side by side. Then, in 1995 came another breakthrough when American physicist Edward Witten proposed his M Theory. M Theory, according to Duff, provided an umbrella for the various String Theory variations that existed at that time.
“At first, there were six different approaches,” said Duff. “And Witten showed us that they weren’t really six different theories but rather six different corners of a deeper, more profound theory that he called the M Theory.”
PROBLEMS SOLVED BY: M THEORY
Theory Of Everything Physics-M Theory also introduced what Duff calls the holographic principle, which states that “the gravitational world in a certain number of dimensions can be described by a non-gravitational theory that lives on its boundary, which has one dimension less,” said Duff, admitting that the claim, while rather “astonishing,” seems to work.
Still, the Theory of Everything is far from worked out, Duff said. Most importantly, physicists still don’t know how to pick out from billions of possible string-wrapping combinations the one combination that fits our universe.
“Whether M theory is the right theory or not, we don’t know, but it’s the most promising candidate,” said Duff. “But if it is, how long it will take us to figure out all the details is anyone’s guess.”
THE THEORY OF EVERYTHING’S MISSING PIECES: AXIONS AND DARK MATTER
INTRODUCTION: THE THEORY OF EVERYTHING’S MISSING PIECES
Theory Of Everything Physics-In the meantime, scientists keep looking for the missing piece of information that could plug the holes in a potential Theory of Everything. Experiments in particle accelerators such as CERN’s Large Hadron Collider in Geneva, or observations of the most distant universe may one day produce the breakthrough that generations of theoretical physicists have been waiting for.
That breakthrough, Reynolds said, will most likely come from research into the nature of dark matter, the elusive invisible substance that must make up about 85% of all matter in the universe to explain the gravitational behavior of galaxies and galaxy clusters.
DARK MATTER IN THE STANDARD MODEL: THE THEORY OF EVERYTHING’S MISSING PIECES
Theory Of Everything Physics-“There is no explanation for dark matter in the Standard Model of particle physics,” Reynolds said. “There’s something out there that we just have very low-fidelity data on. If we could somehow detect those dark matter particles or detect some signature of dark energy [the force driving the accelerating expansion of the universe], then that would start to really say whether the Theory of Everything is really something along the lines of String Theory or whether it’s something completely different.”
WHAT WILL HAPPEN IF WE FINALLY CRACK: THE THEORY OF EVERYTHING?
Theory Of Everything Physics-What will happen when all the pieces of the puzzle finally fall into place and we understand how our world works? Will that be the end of physics? Duff disagrees. After we learn the “rules of chess”, he said, we can finally “start playing the game”.
Cracking the Theory of Everything will surely lead to a flurry of Nobel Prizes. But what comes next? We will have to wait and see.
Challenges in Finding a Theory of Everything
Theory Of Everything Physics-The search for a theory of everything is not without its challenges. One of the biggest challenges is that we currently lack the technology to test many of the predictions made by these theories. For example, string theory predicts the existence of extra dimensions, but we currently have no way of directly observing these dimensions.
Another challenge is that many of these theories are highly abstract and mathematical, making them difficult for the general public to understand and for scientists to test. Additionally, some theories, such as string theory, require a level of mathematical sophistication that is beyond the training of most physicists.
Alternative Approaches to Understanding the Universe
Theory Of Everything Physics-While the search for a theory of everything continues, there are other approaches to understanding the universe that are being explored. For example, some scientists are investigating the possibility of a multiverse, which would be a collection of many universes, each with its own set of physical laws.
Another alternative approach is to focus on specific aspects of the universe, such as dark matter or dark energy, and try to understand these phenomena in more detail. While these approaches may not provide a complete theory of everything, they can still lead to new insights and advancements in our understanding of the universe.
Implications for Philosophy and Religion
Theory Of Everything Physics-The discovery of a theory of everything would have significant implications for philosophy and religion. For example, it could provide a scientific explanation for the origins of the universe and the nature of reality, which could challenge certain religious beliefs.
However, it is important to note that science and religion serve different purposes and can coexist. The discovery of a theory of everything would not necessarily invalidate religious beliefs, but it may provide a different perspective on these beliefs.
