    @lyco46 I have to disagree. God made us far more complicated than that analogy although it does work on a surface level. I think we are that but there are/is another component/s involved. What that has to do with time I'm not sure but I agree with most of your latter statement. It's as if it's a Being John Malkovich situation except you're under the illusion your in control. I think what we are experiencing is a different thing considering God gave us free will.

    Sean Carroll My understanding is that what we call "time" is altogether inferred from change, and that we compare the physical changes in one system to the physical changes in a reference system (called a "clock"), and that is where all our measurements of T are derived. Thus "time" is never really observed directly. What we call "the past" is our mental (or any) record of past physical state. What we call "the future" is the physical state yet to be. And, in fact, the part of the brain which discerns the "passage of time" seems to manufacture it by comparing our record of "past" physical states to present physical states, and this facility can be disabled, for instance with DMT, so that "past" and "present" become indistinguishable. (And people find this "timeless mind" to be a very weird experience.) Now, when it comes to perception or detection, of course all perception relies on contrast, and all detection relies on physical contact. If "existent time" is a linear continuum with no cousins, there is nothing to contrast it with, and therefore it is undetectable. If, on the other hand, there is only change, arising in the present from what we might call a "perpendicular" time-line, then in that sense, "time" would be something akin to a "frame" - a threshold of "readiness" at which point the "present" arises before sublimating once more in readiness for the next "present" to arise, and so on. Clearly that is unsatisfactory, but how else can we possibly consider "time" when it really does appear to be a pure inference? Special Relativity requires "T" because it concerns the aforementioned relative physical change, measured against light propagation, and can be taken to say that the observer's physical evolution - their matter - changes less at speeds near "c" - again, physically-speaking, as it proceeds through greater distances, presumably because the spatial propagation of light and the spatial propagation of matter are independent. And yet, something must break down physically at such high rates, because light is electromagnetism, and matter changing relies on electromagnetism propagating with respect to atomic nuclei... I wonder, does breaking it down as purely relative change, or propagation of matter in space, bring any special light (pun not intended) to the situation? Can "T" be replaced with some factor tied more directly to the relative change of discrete physical systems, or does it keep turning up like a bad penny? Another thought or question, related to that... Does electromagnetism bound to atomic nuclei, or within discrete systems, have a different nature, or curl up tighter, or do some extra "magic" compared to electromagnetism freely propagating in less-curvy space in the form of light waves at speed "c"?

    I am probably wrong. But when it comes to marrying Relativity with Quantum Mechanics, this is how I understand it: Its a lot like a huge, pixelated picture. It you view it from right up close, your brain tells you that all you are looking at is a collage of a bunch of random squares. But if you view it from, lets say 50 feet away, your brain recognizes it as a picture of, let's say Elvis Presley's face. So what's the difference then?? The difference is information! Up close, a lot of information is hidden. So it appears to be just random squares. But far away, those "random squares" reveal all the information. & its immediately obvious that each square is a pixel that forms a portrait of a familiar face. So, this is how I understand how the Macrocosm & the microcosm are married. Its about hidden information, which is Entropy aka "The Arrow of Time."

    I like the conception of how to explain QM. yes the whole idea is that its quantised. Like taking a pixel, but the pixel knows the whole picture even when alone, and only comes into being as the picture. If anything that is what quantised means. If you take only a 'point' out of a wave, we found such 'point' knows the whole wave- it has the information, and cares about information, despite only being one. Unlike pixels of a printer they are not in sequence, they are randomly falling until the image of the wave is produced- hence such uncertainties/observer effects. But i dont think this is the true problem of marrying the two. Simple gravity doesnt work and is hard to be some kind of boson. QM essentially neglects time. And i think Carroll had a good explainer of another video. QM rarely deals with something massive or deal with trying to put enough particles together. So he was explaining it as emerging from entanglement added up over vast collections of particles.

    Fair enough. I guess what I meant about the 'point of reference' thing is that we continue believing things are 'one way' when they are really another because we follow this point of references. Like the whole wave vs particles example. For ages people thought that atoms on a quantum level behaved like particles and now they have discovered otherwise. But no worry, I do have "faith"in the scientific method, which generally has been good at keeping everyone on their toes and honest.

It is the way our mind -in a way trapped in our bodies- makes sense of the stimulus around us. We wouldn’t be able to make sense of the physical world we live in if we didn’t take events that we perceive as previous into consideration to explain the moment we live now.

    @@ShadowsMasquerade because you can often find states of very uniform things being high entropy. You can find chaotic looking things with low entropy. The definition is more like "how many times can you rearrange and have it be the same thing". Heat death is high entropy. Yet is complete immobility, lack of heat, evaporation of particles. Id say a state close to nothing happening is the opposite of disorder. Entropy is rather the force to average and level out all energies. Sometimes that produces disorder along the way. Sometimes. Too stuck on the notion of having some neatly categorised things, ending up jumbled. Like lining up colours of m+ms then having someone knock the table, so they become 'mixed up'?. That is an analogy i guess... Only goes so far.

    I am new to this discussion, hence I apologize if I repeat some ideas than other have already said. I think there is fundamental flaw in the picture the physicist portraits. The so called Newton-Laplace idea (or should I call it the Newton-Laplace myth) only works if we assume smoothness. As soon as there are singularities that claimed capacity to perfectly predict the future and know the past fails. A trivial example would be the following: a particle impacts a surface at a corner. The singularity at the corner prevents the application of whatever differential equation you are using to be continously valid after that moment. I hope I explained myself.

    After a 40 year career in physics I don't think I've known a single physicist make the claim that we "know the laws of physics perfectly." From the time Einstein wrote his paper on light quanta, which incidentally explained the photoelectric effect, it took 18 years before the physics community finally accepted light quanta with the discovery of Compton scattering. Who "knew the laws of physics perfectly" during those 18 years. Nearly all thought Einstein was wrong and yes, I know he was awarded the 1921 Nobel prize (in 1922) for his explanation of the photo electric effect but there wasn't a mention of light quanta in the award. They HAD to give him a prize for something and since Millikan had shown that the kinetic energy of electrons emitted in the photo electric effect behaved as Einstein predicted they gave it to him for explaining the effect in spite of the fact that they couldn't bring themselves to mention light quanta in the award. A few weeks later Nils Bohr received the 1922 Nobel prize and devoted some of his acceptance speech to trashing Einstein's light quanta theory. After Compton scattering was discovered which cannot be explained in terms of classical electrodynamics the flood gates were opened and then it took about 7 years to work out the quantum theory that we use today. Your version of the history of physics simply doesn't jibe with the history of physics.

    @@BaldingEagle51 I understand Carroll fine. Some physicists are hoping to develop a theory in which time is an "emergent property" of the theory but Carroll expects time to remain fundamental in whatever theory we end up with. I'm agnostic on that particular issue. I'm quite familiar with the issues of past, future, and irreversibility in physics. I've read Paul Davies Physics of Time Asymmetry and various papers published in the physics literature on it the issue which is fundamentally that the second law is irreversible while the microscopic laws of physics are reversible. Usually this seeming contradiction is ascribed to "coarse graining". Einstein once thought he'd derived the 2nd law from "first principles" but then discovered he'd made an assumption that was equivalent to the second law, namely that more likely probability distributions follow from less likely ones. There's no guarantee of that. Understanding you is a different thing entirely. I have no idea what you think this sentence is supposed to convey: "Every single Physicist that has been wrong through history has known the laws of Physics perfectly. " I agree with you that your sentence "makes no sense."

    I think that the key to understanding time is to create a measuring device with quantum computing that utilizes software designed incorporating Heisenberg's Uncertainty Principle; because the only way we are going to break free from the constraints of our sensory limitations, (as the famous Double-Split Experiment has shown) is to automate this foray into these unknown realms; the same way we overcame our physical ability to explore our solar system:)

Time shouldn't flow if there is no interaction or movement. The direction of time of course is caused by entropy changing.

    I once knew a physicist that was working on the idea that time is our awareness of the expansion of space. He passed away before publishing anything. I didn't understand his explanations, but I remember him saying that Einsteins space time is incorrect. That in fact it's "expanding space time". Space and time are different sides of the same thing because space is expanding and creates "quantum holes" which must be filled. The holes being filled created by space expanding is what we feel as time because these "quantum holes" allow us to go from point A to point B in space, or some such craziness that I don't understand. I also remember him saying something about if space didn't expand we could not travel through it. It would be like a solid and there could be no motion, energy or time.

    Time in the abstract sense is a comparative of change while time in the reality sense must incorporate the means of change from which the comparative can be derived and imposed back upon reality in the abstract. Without a clear understanding of the means for consistent, comparable, and directional change we have come to interpret that change in an unbounded abstract sense that must deny any physical means and float above in a realm of self-isolating purity.

    @odonegan4865 , I didn't mean that the overall expansion was slowing down. It's a common fact that it's generally speeding up. I meant that gravity slows it down locally, explaining relativity to the position (in a local gravity well or the equivalent velocity or acceleration) of the observer. If time is not a separate dimension but the expansion rate of the 3 spacial dimensions "and " gravity slows the expansion "locally" then time would pass slower around Jupiter than it does around the Earth and that's Relativity. If time is the expansion rate then that would explain why the arrow of time only goes in one direction that we can observe. I think it would reverse within the event horizon as Space contracts in a black hole. If it does reverse within a black hole, then maybe black holes lead to white holes in the past?

In a room of a vacuum, you would know by measuring the vacuum itself, since a vacuum has virtual particles at the quantum level that pop in and out of existence. There is no true empty in the universe. Change always occurs due to thermodynamics. But even the act of measuring would generate heat, and thus create the phenomenon of causality, which, again, would be time. Time is not just perception, it's the word we use for the observable unidirectional change in the universe. Now, rather time is an actual fundamental dimension (degree of freedom for events to occur) is a more head scratching question.

    Emanuel Kant the philosopher explained that our experience of time and space are a-priori intuitions which our brains must supply in order for us to make sense of when and where we are in the Universe. Without these intuitions, we would be unable to function in the human sense. We would be in a perpetual dream state. Time and Space are experienced by us because they are manifestations of change or movement, which is a fundamental characteristic of our Universe. It is constantly moving, as indeed we are. It is an ongoing event which we are an infinitesimally small part of. I think it is important to understand that we are constantly discriminating space and time and that we are doing it, often unconsciously because we have to or else we couldn't function. That it is in OUR nature (i.e. how we have evolved as living beings) to do so. Other animals I believe experience their world of space and time quite differently from us. They have in reality a different experience of an interval, which Einstein used to replace Universal Time and Space, there being no such thing. For him, Space and Time were aspects of the same thing, therefore he unified them into one all-encompassing concept called Space/Time, which to my mind is the same as saying movement or change. Space/Time is Dynamic Quality the primary experience.

Time is simply an arbitrary metric that we apply to the relationship between cause, effect and probability. Even if energy flows could be reversed we would still perceive things as what happened, what's happening and what will probably happen.

    Time is an interpretation of a sequence of events. Before, during, after. If you base time on a repeating cycle, you can organize other things around that cycle far into the future and speak of past events relative to that cycle. Currently, we relate our events to the rotation of the earth on it's axis (days) and it's revolution around the sun (years). We have split each cycle into subsections to make it easier to relay information that has a shorter duration than a single cycle or starts part way through a cycle. It's easier to use "one hour" instead of "one twenty fourth of a day". But time itself, does not exist. The only thing that exist is the movement of physical objects. And we are making sense of that movement by invoking the idea of time.

    My question is based on time but want to know how a photon carries the information of the objects it interacts with. For example if I have a light on in a dark room full of objects, the photons emitted from the light source reflect/bounce/eject off those objects. But if its the photon itself which allows us to see, how is it we gather this data? Is the photon being changed? If the object has a color the color we see is actually the one being reflected while all other colors are absorbed. But yet when the photons hit our optical nerves or are processed by our optical nerves why do objects retain their spacial position? How is it the photon retains this information? Or is it just that the object is bombarded by so many photons its giving the impression of information gathering when its more like the photons give objects their shape and color based on how they reflect off the object? What does this have to do with time, well if the first aspect of my question were true then time would have to follow the same kind of thing. That time would have to collect, retain or some how reflect information. But how, how can time that seems non-physical retain information?
