Is 'time' fundamental? Does it actually exist at the most fundamental level of reality, or can't we seem to rhyme quantum with relativity, or figure out deterministically how quantum works because we are applying the concept of time to both ontological categories whereas in reality it only applies to one?What if time actually only makes sense macroscopically, but when we look at the quantum level, what we see is distorted by that very time. Because the thing we are looking at is actually timeless. The electron is timeless. The photon is timeless. The entire fundamental universe is a static and timeless network of informational bits, but our mass is preventing us from interacting with the whole thing at once and limits us to a series of snapshots instead. We can never interact with the next snapshot, only with the current one. So it seems to us like the future doesn't exist yet. But a photon doesn't have this impairment, it does experience the whole universe in its static entirety, which is how it flawlessly incorporates information that will be created in the future into its behaviour 'now'. There is nu future. All the data is already there, at the most fundamental level of our existence. We just think it is the future because we have no choice but to view the world through our temporally distorted goggles. We have to wait for the next snapshot to interact with it. So when we look at this static information itself, i.e. 'quantum', we do so through a temporal filter. So it doesn't make sense. It seems jittery. Uncertain. Dual in its existence even. In fact, what is jittery is our temporal perception of it. The thing we're looking at is as static and fixed as can be.In other words: what if 'c' is just the margin of error by which time-prone matter experiences a fundamentally timeless, informational universe?
To the question of time-prone matter in a timeless informational universe, it is a rich environment for though experiments. Getting right to the crux of the matter, it seems that if we can alter the future, the answer is no, “c” is an actual physical limit imposed by the natural laws of the universe.
Why do I equate the two? Your argument for timelessness fails if the future isn’t deterministic to the extent that the path of every photon is pre-established. If I can alter the path of one photon, timelessness as you imply it, is false.
we cannot establish a testable experiment that will lead to irrefutable proof that convinces both sides.
I am on the freewill side.
We already have testable proof, and the best part is that we still have no conclusive explanation for the phenomenon that proves this, only a very good description. The photon already knows if we will store the which path information in the future, even if we leave that decision up to a completely 'random' process IN THE FUTURE. The photon guesses it right every single time.
This clearly implies that to it, there is nothing random about the process. Clearly to it, there is nothing random or even 'future' about our 'random', 'future' 'choice'. What more proof could you wish for?
Nice to meet you.
I have an explanation, but your testable proof, and my explanation, will not change either of our minds, probably. “Irrefutable” seems to be the key word. I can refute your explanation, which I will do, and you may not be convinced.
Here is a diagram of the delayed choice quantum eraser apparatus setup. It is designed for single particles to be sent through; one at a time. Even with only one photon sent through at at time, the interference pattern eventually takes shape on the screen.Is that the experiment you are referring to?Because I have some things to point out, if it is.

I have no idealistic connection to determinism, it just seems to make the most sense to me right now, based on this timeless universe model.

Apparently the photon experiences a deterministic universe because we consistently observe it to perfectly incorporate our 'random 'future' decision into its present or past behaviour. It never gets it wrong. So evidently, to it, the world is as deterministic as can be. To it, there is no random event, or even a future event, the event is already there and the photon interacts with it just like everything else does at quantum: instantly. I am curious about your comments though. Thus far I have only found QM to be descriptive and predictive about this 'delayed choice' phenomenon, but by no means explanatory. The fundamentally static, informational universe, whether one would agree with it or not, is an explanation where the predictions of relativity seem internally consistent with the quantum results. If you assume that time is real at quantum scale, there is no way, or at least none has been found yet as far as I know, to marry the two.
You are correct, there is an erasure feature, but the experiment, after the erasure, gives results, where the interference pattern appears on screens D-1, and D-2, but not on D-3 and D-4, if I am seeing it right. Does that agree with the results that you are familiar with?
I interpret that to mean that because you see the universe as timeless, that there is nothing new under the sun, if you get my drift. The universe knows, because there is only one grand “now” and it is all stored in the information that “is the universe”.
My “freewill” and “randomness” influenced reply is that neither the photon, nor the universe, knows anything in advance. The future unfolds as time passes.
The second thing that makes the experiment controversial is the nature of a particle. Wave-particle duality is a growing consensus, but even so, the nature of particle that can display the duality, i.e., both the particle nature and the wave nature at the same time, as in this experiment, isn’t a consensus. If a photon wave-particle can go through both slits, one in its particle state, and the other in its wave state, there is an explanation for the interference pattern.
Notice in the delayed choice quantum eraser apparatus, the paths to each coincidence counter (detection screen) is marked with either the color red, or blue, or both. Note that screens D-0, D-1, and D-2 have both a red path and a blue path, while D-3 and D-4 have only one color (in the case of D-3 it is blue, and in the case of D-4, it is red.If you see that, and agree with my observations of the diagram and the color of the paths, then I will try to make my point.
What if time actually only makes sense macroscopically, but when we look at the quantum level, what we see is distorted by that very time.
time is an emergent phenomenon for internal observers but absent for external observers of the universe
Yes! That is a great way to put it. Just to be clear: by speaking of a 'knowing universe' in this context, we aren't referring to anything spiritual or religious. It isn't a conscious 'knowing' like that of a God. It is just that every bit of information about our reality, past present and future is already there.
That statement to me seems to violate both special relativity and delayed choice. Relativity says the photon experiences everything at once. And delayed choice shows us that this is actually the case. How does your statement support these observations?
How do you feel about the DeBroglie-Bohm pilot wave model? According to it, the photon actually travels as a particle with definite position all the way through one slit to the screen, but it interacts with its own pilot wave and thereby creates a wave that passes through the other slit. So it seems to us that it went through both slits, but one slit just had the wave, the other actually had the particle (and the wave). Since there are still 2 waves interacting on the other side of the slits, you still get an interference pattern even though all photons actually only went through one slit.
It has been seen, let us have your point .
You may or may not want me cluttering up your thread with the description of the wave-particle, and the photon as a wave-particle with mass, but it is part of my explanation about what is going on in the delayed choice quantum erasure experiment. Wave-particles are both a wave and a particle at the same time, and at all times, until they are observed, and then they are one or the other, depending on the nature of the observation. (I will have to give you some details of the mechanics of how that works, but you may wave all this off before that becomes necessary).
As a result of the wave-particle duality of states (not talking superposition of states), they can display both states, when sent one by one, through the apparatus. The particle state is registered as a hit on a detector; the wave state is registered as an interference that affects the path of the particle.
I will address the details of my view on de Broglie-Bohm interpretation of quantum mechanics in a separate post later, if you like, but suffice it to say that I don’t invoke the de Broglie-Bohm interpretation of QM.
The point is that you do not get interference unless there is a path to the detector from both slits, i.e., you need a red line and a blue line in order to get the interference pattern. The reason is, that in the single particle experiment, in order to get interference, the wave state of the particle goes through both slits, while the particle state goes through only one or the other. The interference that alters the path of the particle state must be allowed to form, and in order to form, the wave must go through both slits.
If we get to the discussion of my alternative interpretation of QM, I’ll be able to explain, but I am on thin ice in regard to hijacking your thread, and that is not my intention.
Quantum time is the proper time in general relativity. Since the laws of physics are the same in all inertial frames of reference we can devise a transform for quantum interactions in remote frames. This is separate from coordinate time but can be derived from it. These transforms then make time relative in quantum mechanics for all particle interactions. It sounds easy but is far from it.
As soon as you have 3 or more particles in an interaction, you can identify the direction of time with high probability.Because the probability that 3 (or more) particles would happen to be in exactly the right place, at exactly the right time, with exactly the right energy and momentum is effectively nil.
Over the past few days a small “rash” of threads seems to have arrived between which there is considerable crossover. As I have neither time nor inclination to become involved in repetitive, multi-thread posting, but want to have a say in some of these threads, I’ll give it some thought, decide which thread is most appropriate for any response, and cross-reference where appropriate. I hope that will work.
Nope, not in the business of waving anything off On the contrary, I would be very interested in more details on the observation mechanics and their nature. Please do share. What I don't see in the above idea (yet), is any explanation of the apparent violation of time/causality. It addresses the 'mechanism' of particle-wave duality, but how would this idea in itself address the observation that the photon flawlessly determines what the outcome of our 'random' 'future' event will be?
I would love to get your thoughts on that.
I get that line of reasoning (I think). But still, this is addressing only the particle-wave duality issue. Not the causality defying one. Unless I'm missing something.
Not at all, lets discuss it. But since the thread is about the fundamental existence of time, lets try to stick to that. So please, tell me, how does your model explain the apparent causality violation of the photon?
