Proof and explanation how something comes out of nothing!

0 = -x + x

This means two things, and it is actually not quite “something comes out of nothing”. It really means superposition of everything is equal to nothing, not identical and not because it is actually nothing, but because it is effectively nothing.

Totally chaotic arrangement of everything cancels out itself, it is there but without an effect or defined form in any direction or dimension. It means nothing actually implies everything, it can not exist without it like there is no black without white.

No yang without yin. So nothing is not simply nothing, it is also everything. And another duality is that what comes out of that “nothing” can not be just any old something, it must be paired into two opposite some-things. It’s undeniable!

If you conceptualise nothing as a formless entity predicated on the absence of particulars, sure

If true "nothingness" to you is however the absence of comprehension itself, something that cannot be given a word, something that cannot be described something that makes the notions commonly associated with the word 'nothing' feel like a pebble thrown in to the ocean, then perhaps not.

Because you would not find a relation between your conceivable somethings and the nothing.
If you had this view when I say the word nothing you would feel as if I am not talking about anything, anything atall, for it is impossible to know what it is.

It is like saying what would there be if I took away everything? Would there be nothing?
I don't think its far fetched to say contemplating nothing doesn't exist, the moment you think of whatever you are confusing with nothing, it becomes something.

If there were no particulars to observe, how would we formulate an idea of what would be without them?
Once we attribute some thought to the common idea of "nothing" it isnt nothing anymore.

I don't believe in proof of particulars myself, I only believe there that there is proof that there is.

Furthermore I like to say that what exists rather 'exists' independant of how we structure it in our minds, and that true nothing is not something we can comprehend.

I don't think anything is undeniable other than the statement that there is.

I mean in its literal or physical sense. There is an aspect of testable reality there. Namely, the reason why things are mostly neutrally charged. Also, that is how metal can be magnetised and demagnetised - if orientation of all the magnetic dipoles is uniformly chaotic they cancel each other, just like -x + x = 0.

Or keep electron and positron at the same point in space and you will walk through them, would not be able to see them, detect or interact with them in any way. Effectively, practically, they will be nothing, Now, if practically nothing is still not nothing, then in what way it can be something, or anything?

Reply to Zelebg That's not nothing. That's a lot of laws and patterns. You used the word 'superposition', which means that there were potentials. There was some tendency, which had the superpostion collapse. You had a situation. That is not nothing.

If nothing could simply split into -x and +x, it could also split into -monkey and +monkey. Not particles or singularities. Two monkeys, one an antmatter monkey appears. But only certain things could appear. There were rules and structures in whatever you are calling nothing. And they ain't nothing.

Yes, potential, which is abstract concept, it is not really a.thing, so it is no-thing. I'm not talking about quantum vacuum, virtual particles, or any such QM spooky stuff. This is classical physics, the fields literally cancel out to produce pure nothing, just like -x + x = 0.

-monkey + monkey = 0, it computes!
Deleted User January 08, 2020 at 16:27 #369767
Reply to Zelebg Well, the fact that it is not monkey and -monkey means there is something that is there making it not monkey and -monkey. Also in Classical physics you do not have nothing. Things there are no anti-things in classical physics.

And it is not just potential, it is laws or rules, or tendencies. Which is not nothing. In our world which is something, you have what we call potential, which is really just a shorthand term for built up energy and the like, NOT abstractions. Nothing cannot have all these qualities and be nothing. It is some kind of thing.

There is this hypothesis that ties in with the theme of the OP:

https://en.wikipedia.org/wiki/Zero-energy_universe

But I feel it cannot explain the origins of the universe:

1. Some driver for the creation of matter from negative gravitational energy is required. So it cannot be a true something from nothing event; something must pre-exist it to act as a trigger.

2. If something can come from nothing naturally and past time is infinite, then matter density would be infinite by now, which is clearly not the case. So 'something from nothing' mandates a start of time which would be the creation event of the universe.

Every addition and subtraction equation directly maps to the real physical world. If you look at it from that perspective it would be really strange equation “-x + x = 0” suddenly doesn’t correspond to reality, and the real mystery is then how can there exist ‘anti-things’, what are they, where are they. And if we find antimatter exist, then that proves the equation is indeed true in metaphysical sense as well.

No yang without yin. So nothing is not simply nothing, it is also everything. And another duality is that what comes out of that “nothing” can not be just any old something, it must be paired into two opposite some-things. It’s undeniable!


First, duality. Why is it that the concept of duality has emerged in both Eastern and Western thought? Daoism has yin-yang, Buddhism has the middle-path and Heraclitus too spoke of opposites and don't forget Aristotle's golden mean. If this means anything then it must be that the dualistic model is more than just a culturally idiosyncratic point of view and that it's a good representation of reality.

We can only guess the origins of dualistic thinking but one thing is clear: duality is about extremes. Look at dualistic pairs e.g. hot-cold, large-small, create-destroy, etc. Each pair expresses extremes of a particular property a thing may possess: hot-cold are extremes of temperature, large-small are extremes of size, create-destroy are extremes of existence, etc. Given this is so, what do we make of the in-between stuff e.g. between hot and cold is warm, between large and small is medium, between create and destroy is preserve, etc.

The existence of words that capture the stuff between dualistic pairs betrays the fact that dualistic thinking doesn't quite give us the correct or, if you prefer, the complete picture of reality. Nevertheless, dualistic pairs do provide a useful guide to where we should place ourselves in the universe - right in the middle where things are comfortable and exciting because all phenomena seems to occur between lower and upper extremis points. Life, as we know it, must avoid extremes to survive. In a sense then, all the dualistic philosophers I mentioned were deliberately or unwittingly affirming the Goldilocks zone for life. This also means, quite oddly, that dualistic thinking is an implicit claim of not a duality but a trinity, the positive, the neutral and the negative; it is best conveyed by the Hindu trinity of Brahma the creator, Vishnu the preserver and Shiva the destroyer.

One more thing I want to mention is the concept of negation; it has the ability to split the universe into two, a thing that is affirmed and the rest that is negated. Is this duality? Yes, because an entity and its negation are definitely opposites and no, because these opposites aren't always extremes. The negation of cold is not-cold and that, despite referring to the dualistic opposite hot, also refers to warm. This isn't useful since it fails to point to the other extreme. Imagine if the words "hot" didn't exist and someone were to claim that a cup of coffee is not-cold. Is that enough information for you to take a sip of the coffee? No, the coffee could be hot and could burn your mouth. Negation, though technically dualistic in nature, isn't adequate; we need a separate dualistic worldview based on explicit consideration of extremes.

Secondly, the matter of nothing, something and everything. You made an amazing argument and I really liked the -x + x = 0; expressing duality mathematically makes the whole issue clearer. I'd like you to imagine a world made of 6 things: a, -a, b, -b, and c, -c. Everything would be {a, -a, b, -b, c, -c}, and something would be a combination of these but not all of them. Nothing would be again {a, -a, b, -b, c, -c} because every object and its opposite would cancel each other. So, everything is nothing.

Duality would impose the condition that everything have an opposite and that includes everything itself and also nothing. What is the opposite of everything and also the opposite of nothing? If one is to be dualistic then we have to talk in terms of extremes; if we take everything as one extremis what would be the other extremis? Wouldn't it be nothing? Your mathematical treatment of the matter produces a beautiful answer to the question.

Everything (e) = nothing (0)

Opposite of everything = -e

1. e = 0
2. -e = -0 = 0 = e
3. -e + e = 0
4. e + e = 0 + 0 = 0 = e

The opposite of everything is nothing and that too because everything is nothing.

My concern is whether a mathematical representation of the issue is apt or not. Can I speak of duality in terms of positive and negative numbers?

Well, nothing, something and everything appear quantitative and we can express it mathematically as follows: nothing (0) < something (at least 1 but not all) < everything (the entire universe). This is an accurate mathematical translation as far as I can see but it lacks the positive-negative feature of numbers your argument has. Notice that in my mathematical model, dualistic thinking assigns the opposite of everything as nothing since they're extremis points. However it doesn't allow me to conclude that nothing is everything as your model with positive and negative numbers does.

Anyway, if there's any problem with the -x + x = 0 model of reality, it's the reliance on negation to "take care of" the stuff in between -x and +x since, generally speaking, there are no opposites for the in-between: for instance hot and cold are opposites but there is no such thing is an opposite for warm unless you say not-warm but that creates 2 possibilities, hot or cold, raising the count of states that can be obtained to 3 which is not a duality but a trinity. Perhaps it's a trivial truth.

What else?

Given no point for Everything to have any input, since it can't have a beginning, it must be everything in a superposition because it cannot be anything particular.

Indeed, as it somehow plays out to us, it doesn't remain as anything particular even for an instant.

Effectively, the information content of Everything in superposition and Nothing are both zero.

I hope my point with the antimonkey was clear at least to someone. The so called nothingness was able to separate out into opposites. That's a nothing with qualities, and so not a nothing. Those opposites weren't monkeys, they were particles or waves or branes or whatever current theory is. So, that nothing had even more specific qualities. Lawrence Krauss wrote a book 'demonstrating' how something can come from nothing. In fact, I think he went so far as to say it must, though it's been a while since I read it. While he's a physicist, his book had the same problems this thread does.

His nothing are laws of quantum physics and quantum vacuum. That is not nothing, it’s lame attempt at explanation that does not explain. I guess you could say we are describing the same thing, but I think what I said actually explains or at least makes more sense.

I say logically nothing can not exist by itself like black can not exist without white. I’m saying nothing and everything is one thing with two sides. It is everything that can manifest as practically and effectively nothing by cancelation, if everything is uniformly chaotic.

So default mode of everything is to exist as nothing. And then, for some reason, in all the chaos some dimensions of everything interlock in harmony and establish a stable attractor state. This part of harmonic everything then materializes as something, something like big bang I guess. It’s consistent with Greek mythology. https://en.m.wikipedia.org/wiki/Chaos_(cosmogony)

Well, his explanation includes this same borrowing from nothing in two directions.

I don't see any evidence that the universe had a beginning. (the Big Bang was certainly a change, but there is no evidence there really was nothing or nowhere. ) And it seems to make more sense that it's always been around. I suppose that's my default. Now I get that what I just put forward is my intuition and no one has any reason to buy that. However I see no need to start showing that nothing can lead to something, and there has been a trend away from starting from nothing in cosmology.

Reply to Coben The universe can only have one of the following as its average long term behaviour:

1. Expanding. This is what science says.
2. Contracting. Impossible. One big black hole
3. Steady state. Impossible. Leads to 2
4. Cycling. Impossible. Loses energy on each cycle, leading to 3 then 2

There is an explanation for God's existence; he is uncaused because he is from beyond causality, IE beyond time.

That doesn't explain God's existence it just asserts that he's uncaused. Any first cause is uncaused, so this alleged "explanation" is equally applicable to any first-cause state of affairs.

The first cause cannot be "beyond" causation, it obviously must be the initial point in a continuous causal chain. Nor can it be "beyond time", because causation reflects change over time - there can be no causation without an elapse of time.

You will undoubtedly rationalize all this, but it will require making just the right assumptions that preclude a natural first cause while permitting a supernatural one. But this doesn't actually prove anything.

A start of time needs a cause from from beyond spacetime. Each cause requires a prior cause. The chain of causes cannot stretch back forever; ultimately we must arrive at an uncaused cause. An uncaused cause must be able to effect things without being effected itself; IE self-driven, IE intelligent.

Monkey and anti-monkey cancel each other in chaotic arrangement before they can manage to materialize. Something materializes only through windows of harmony which supposedly are small in totally chaotic system or things disintegrate into particles for some other reason.

Harmony in chaos of everything means separation or organisation between things and anti-things. Separation weakens cancelation which reveals the underside of nothing with a tiny hole, or two, through which pours two streams, matter on one side and antimatter on another. This reminds of those giant black holes in the center of galaxies.

In theory, spacetime CONSISTS of quantum fields. Collectively, these comprise a quantum system. In this context, a quantum fluctuation is not a temporal event. The initial quantum state is zero-point energy; a quantum state is a superposition of all possible eigenstates, each with an energy value of (zero + a value associated with the uncertainty principle).

An eigenstate with high energy/low entropry will necessarily inflate, either collapsing the quantum system to this state, or (if Many-Worlds interpretation is true) - in a world that branches off the initial superpositioned quantum state.. The "cause" of this inflation is the high energy of that eigenstate; the existence of that high energy eigenstate is just a consequence of the quantum uncertainty of a zero point energy system - the quantum system as a whole has "zero" energy. Therefore nothing external needs to cause it to inflate.

Quoting Devans99
A start of time needs a cause from from beyond spacetime.
"Spacetime" may not be the right label to apply to the initial state I described, but it is clearly doesn't require anything external to inflate and become what we call a universe (spacetime). The "cause" is its high energy, and the initial high energy is a consequence of the quantum uncertainty of a zero point energy.

That's another big, convenient assumption. Why assume they should be causally connected (which just means they are detectable)? The fact that others have not been detected could mean there's just the one, or it could mean they are merely causally disconnected. You eliminate possibility #2 by assumption, and that's irrational - there's no basis for this, and so it simply sounds convenient.

I'll also add that even if there is but one inflationary landscape, that doesn't preclude the scenario I gave of inflation occurring from a high energy eigenstate, which results in the quantum collapse of the other eigenstates.

On the other hand: x - x does not mean "you have x, you have its negation, and the two cancel out each other." The original meaning of the minus sign is "take away", and it is not "negate" or "create the diametrically opposite." X take away X means that you have an X, and you then take it away, meaning putting it somewhere else. This is simple.

That's another big, convenient assumption. Why assume they should be causally connected (which just means they are detectable)? The fact that others have not been detected could mean there's just the one, or it could mean they are merely causally disconnected. You eliminate possibility #2 by assumption, and that's irrational - there's no basis for this, and so it simply sounds convenient.


If inflation was a natural event then it should occur with the frequency of a natural event (eg supernovas). Each instance of inflation expands outwards so it would be like the expanding rings rain drops make on the surface of a pond - all of the instances overlap in space leaving evidence of each other detectable.

Inflation strikes me as quite a 'tall tail': it has the universe increase in size by a factor of at least 10^26 between 10^?36 seconds and 10^-33 seconds after the Big Bang. I know that the CMB shows good agreement with inflation's predictions but I still think it should be regarded as a speculative theory. I believe firmly in the Big Bang - an expanding universe is the only possible sort that avoids equilibrium - but the details of what exactly happened 14 billion years ago are opaque to humans.

Reply to Zelebg It's just confused.

If I have a million dollars in the bank, and yet I also owe a million dollars, I do not have nothing. I have a million dollars in cash and a million dollars in debt.

If I use some of the million to buy a Ferrari, I have not bought it with 'nothing' have I?

Everyone has a right to an opinion just as much as cosmologists do. Many cosmologists think time has no start so clearly there is a considerable number of them that do not know their arses from their elbows on even basic matters. And speculating deductively is surely what this site is about?
Sure, as long as people know they are speculating. I said nothing about you shouldn't have had an opinion or expressed it here.

If I go back to where I came in...

The universe can only have one of the following as its average long term behaviour:

1. Expanding. This is what science says.
2. Contracting. Impossible. One big black hole
3. Steady state. Impossible. Leads to 2
4. Cycling. Impossible. Loses energy on each cycle, leading to 3 then 2

Any expanding universe must have a start in space and time (see BGV theory).

Lawrence Krauss wrote a book 'demonstrating' how something can come from nothing.


I see statements of certainty.

And I guess if I was ruling something out via deduction, I would wonder why many of the experts in the field are not ruling it out. I could of course be right and they, wrong. But I would wonder why the experts do not rule out what I rule out and try to explain why they are off base. What they are missing. Deduction's accuracy is affected by assumptions, including metaphysical ones.
