What is quantum gap and unified field? Please explain it fully in mathematical terms.

[Graybeard]

Hmmmmm .... thats a really tough one Lakshya.

The Theory of Everything, on this forum, is probably best described as the theory that would unite the four known forces. The strong nuclear force, the weak nuclear force, the electromagnetic force and the gravitational force. In effect, such a theory would describe all physical aspects of our universe.

As these four forces 'transmit' or 'exert' their influence through fields, a Unified Field Theory would unite these four fields into a single field.

So far there is no Unified Field Theory, nor a Theory of Everything.

I don't know what sort of mathamatical explanation you require for the above?

The 'Quantum Gap' is something I know very little of, or even if I am talking about the same gap as you.

Quantum mechanics can be used to determine the 'efficiency' of the way light interacts with matter. This efficiency is never reached in experimental practice, in fact not even close.

Why? Nobody knows. However this gap between 'desirable' and 'achievable' is not a fault of QM. QM will only be at fault if the efficiency predicted by QM is surpassed. So far the shortfall in efficiency is being slowly but surely bridged by physicists making better and better compounds.

But QM says nothing at all about this gap. It simply says that the limit QM sets can never be surpassed, nothing about why we can't seem to get close to the limit

Should it be surpassed QM will have been demonstrably proven wrong.

The great achievements of bridging this gap will result in many benefits to us. The internet will be many times faster as fiber optics improve the data bandwidth for example. Or say, spectacles, for people with vision defects, will be able to pass more light through the lenses. Movies will be more realistic.

I don't know any formulas for these calculations.

Lakshya, you must be developing an interesting theory if you are combining a Unified Field and the Quantum Gap.

best of luck ... greg

Which quantum gap are you talkiong. I read about it in Theory of everything yahoo group. I am pasting the message below.

The Physics of Realization.
Particles do nothing in Physics. The Unified Field, Quantum Gap, makes particles appear to do things. Particles APPEAR to do things by coming and going through this quantum-gap without NEVER-EVER entering it.
IN physics ALL change is appearance because the only change possible comes from particles/waves appearing to go from one quantum-level to another, "change," without the particle never-ever entering the quantum-gap.
If the change was real then the particle would go into the quantum-gap on one level and leave it on another: which is impossible because no particles can never-ever enter the quantum-gap.
There is absolutely NOTHING subtle about this impossibility: if just one particle entered this quantum-gap it would instantly vanish the whole universe.
And if this all sounds stupid or surreal then it is no more surreal than the past and future, time, continuously going through the NOW without NEVER-ever entering it. If just one-second of time could somehow enter the Now – then that impossibility would also instantly vanish the same Universe.
In a movie – the light falling onto the screen doesn't do anything: the screen makes it appear that the light is doing something on the screen.
In a book words don't do anything, the paper the words are written on allow the words to appear to do things.
So too in a dream, and a dream is no different from life. This is because what an atom is to a molecule is EXACTLY what a dream is to life. The mind and its body is not doing anything because the SELF makes the mind-body appear to do things. The SELF is the quantum-gap/ Unified Field, Now.
The Awareness that the mind and its body is not doing anything is the Awareness of Being the Self, call it "SELF-realization. "

When this Awareness is pronounced
then there is an indifference to what the mind thinks it thinks
and what the mind thinks its body is doing for it, thoughts.

The Awareness is that there is NO connection between what the mind thinks and what the body then appears to do... just like there is no connection between what one word in a book appears to do on another word in the book.
If this impossible-connecti on between thoughts and action were in fact possible – if thoughts and action were connected -- then there should be no reason an addict could not have a thought that would cure his addiction... and there would be no reason a priest could not have a thought to drink holy-water so that it would stop him from molesting children... and there would be no reason that Osama bin Laden could not give George Bush a thought that would make him explode with laughter, by screaming out to the world that even if all the terrorists in the world could miraculously unite they would have to be super-insane to unite just to implant thousand of pounds of demolition explosives into three skyscrapers just so Bush could use 911 as the super-perfect excuse to invade and plunder their country with a super-psychopathic audacity that rockets Machiavelli' s Power Politics into space, with a super-psychopathic audacity that makes any psychopath look like a saint, with a super-psychopathic audacity that would have to make the biggest mass murderers in history weep with envy.
When this Awareness turns affect and effect, cause and effect, into fiction... when this Awareness becomes obvious then the veil-of-matter vanishes to reveal that life is exactly like a movie in which the body plays its part regardless of what the mind thinks it thinks. And thus it can make no difference if the body is slaughtering mankind for George Bush or saving it for Osama bin Laden, because it is all fiction that the SELF makes APPEAR real: Purely for its OWN entertainment, its SHOW, Lila, Maya.
And the SurrealBliss of kundalini
is the SELF being Stoned enjoying its SHOW
being the SELF.
-- words, fiction, Maya, to Stone the SELF

Please if you understand the meaning of this message, then pleasetell me.

Lahshya ... I see from your profile that you are thirteen.

The message you pasted 'The physics of Realisation' is not true.

The person who posted it has only a very small amount of Scientific learning and understanding. He or She has misunderstood, or chosen to exaggerate, this small amount of knowledge into something that is crazy and untrue. The person who posted it probably believes that it is true, but it is not.

1 .. The Science of the Universe from the very largest Galaxy down to the level of the Atom is defined by Newtons laws of Physics and Einsteins Theories of Relativity. If you want to understand more about these you will need to go to this site which will explain them in detail and in a manner, including animated Graphics, that you will find very easy to understand.

This one will explain Einsteins Theories of Relativity

http://www.phys.unsw.edu.au/einsteinlight/

This one will explain all the Laws of Physics as discovered by Newton and Einstein and many other extremely clever people

http://hyperphysics.phy-astr.gsu.edu/hbase/hph.html

2.. Unfortunately these Laws of Physics do not explain what happens once we look inside the Atom itself. To understand what happens inside the Atom we need another set of Laws called Quantum Mechanics. Quantum mechanics is very difficult to understand, and many people become confused when they try to interpret its mathamatics into how the world around us behaves. The person whose post you pasted is one of these confused people.

You can find out all about Quantum Mechanics on the second link I have posted above. But I suggest that before you do that you first try to understand all you can about Newtons Laws of Physics as well as Einsteins theories on Relativity.

1. Newtons Laws have been experimentally proven many times.
2. Einsteins Laws have never been proven wrong.
3. Quantum Mechanics has never made a prediction that has ever been proven wrong.

The Unified Field and the Quantum Gap are two different things, not one thing. The general idea of both is how I have explained them.

If you need any more help just ask ... greg

Although I am 13, I am very much interested in physics. I study in 9th grade and live in a poor country like India. I am reading about relativity and quantum mechanics from past one year and I want to say that I completely understand SR but I have some confusion about GR and QM. The reason I have studied so far in physics is that I was very much excited about how this universe works, who made this universe, what am I, what is thought etc. from my childhood. I want to make TOE when I grow up. The problem is my country. There is no development in advanced physics in this country. So, study material is much much less. Another thing is that the opportunities to rise in this field are very less in this country. So, I want to take my graduation in UK or USA.
So, graybeard don't post me websites which are in layman's language. You can fully discus about the main topic - The Quantum Gap.

[Graybeard]

LOL ... Ok Lakshya

But I don't really know a lot about the Quantum Gap.

The sites I posted are not really laymans sites. If you check them you will find they have a great deal of information. But neither of them have anything on the Quantum Gap.

So far as I know the Quantum Gap is as follows.

Quantum Mechanics describes the way light interacts with matter. As an example photons striking on a sheet of glass have a probability of either reflecting or passing through. All matter and light interactions can be described by QM equations.

There is a limit to the 'efficiency' of these interactions. QM says that this limit cannot be surpassed.

But in reality when the molecular structure of different materials is tested, far from achieving the limit, scientists can not even get close to it. The difference between what can be achieved by science and what is predicted by QM as the theoretical limit is known as the Quantum Gap.

Science, in the manufacture of new synthetic molecular compounds, have managed to narrow this gap but are still not close to achieving the limit.

Carbon 60 is such a compound.

The benefits of getting closer to the limit will affect the way we live in many ways. Anything that interacts with light will be affected eventually.

EG: Sunscreen, sunglasses, solar panels, car headlights, lighting, paint, etc. All have the possibility of being 20-40 times more efficient than they currently are. Fiber optic cable will possibly be able to carry 40 times its current data rate. Industry is doing its best to achieve the QM Limit.

This is known as bridging, or breaching the Quantum Gap. The fact that we are unable to breach it is not evidence that Quantum Mechanics is wrong in predicting it. Quantum Mechanics will only be wrong if we manage to surpass it. QM predicts that we will not be able to surpass it. It says nothing about not being able to reach it.

This is all I know, in laymens terms, and mathematically, about a Quantum Gap

I understand your concerns about the so-called "quantum-gap" and to be honest with you... I share the same concerns but in a different angle.
Your quoted argument speaks about the 'impossibility of "particles" to go throught the GAP and never come back from it, I see the phenomenon the entire opposite way. I'll explain soon, but let me quote something I self-published in my book once about truth and lie... "The perfect lie is always the exact 'mirror-image' of the truth."
This could be the origin of the paradox we (humans) are trying to unveil unsuccesfully. It is the existence of those "particles" [makers of the atom as we know them] the eternal cycle of an alternate existence (reality) sustained by an energy resonance between two "dominiums" - two different mediums we have identified by the abreviations CPT (charge, parity and time). The GAP is protected -not by a supisticious 'gate' or some sort of cataclismic calamity threat but- by the internal structure of those energy-interaction we call orbitals.

I've said in my posts that the time-fractions between the so-called magnetic field and the electric filed (anti-bonding zones found in every single atom of the periodic table) and the spatial coordinates where chemical bondings form are so small that no measuring instrument could detect it.
It would be as if you were capable of observing a process that elapses faster-tan-light... you can't.
It is due to those time-fractions that uncertainty and probability took place in our physics today. Don't forget that Heisenberg employed a microscope in his study that concluded in the discovering of what he named "the uncertainty principle" and that microscope worked with light...not faster than "c".

QM is based on probabilities and gives us very good results in technological achievements, but it is still far from offering us a complete description of what I consider to be more than just 1 (one) physical reality, but 4 (four) inside the time-gap equivalent to one wavelength of a photon="c".

HBD

I hope you'll find a different alternative approach to your GAP... Keep asking yourself, it is the only path to knowledge and self-realization.

[PoPpAScience]

This Quantum gap question and discussion is a good one. Graybeards very helpful information and humanbydefaults great definition gives plenty of answers and food for thought. Thanks.

[neutralino]

Good posts, Greg. I've never heard of a "quantum gap" but you give a good summary of it.

Further, Lakshya, I'm not sure what sources of information you are after. The first link that Greg gives is to a university website, and the second is to hyperphysics (a website written by a university physics department which is basically a physics encyclopaedia). These are, as Greg says, not lay-person sites. If you want to learn QM properly, you will however need to use a text book.

Finally, be careful what you read on the internet, as most of the sites out there are not sites whose scientific content can be trusted. I think I've said this before somewhere here, but generally, sites ending .edu, .ac.uk or .ac.** can be trusted, as they are university websites. I would be wary when reading anything on a .com website as there's nothing to say that it's correct!

Dear HBD ..... I think I may have a different interpretation than yours to the 'quantum gap.

I don't see it as a physical gap ... but as a percentage difference between the maximum efficiency achievable and the actual efficiency we have been able to achieve so far. To breach or bridge this gap is to improve the efficiency of the light interacting properties of the compound.

A banal example (figures made up) would be that if a sheet of glass was capable of passing 90% of light and reflecting only 10% then its efficiency is 90%. But if in practice the best efficiency we can achieve is 20% and 80% reflected then the 'Quantum Gap' is 70%. (the difference .... (90% - 20% ) = 70% Gap

As to the Quantum Mechanics behind the 'maximum efficiency' achievable I know nothing. Perhaps it is to this part you are referring ?
