Best channel on you tube 🙏🙏
Lee Smolin was by far my favorite interviewed expert in this episode... thank you.
The cheapest way of time travel is taking a nap, you close your eyes and leap into the future.
Right that's why we all are time travellers 😆😆
you’ve time travelled from the time you started reading this comment to right now
@@rameezpatel8784 I was going to say that you blew mee mind, but the more I think about it, the more I realize that we are constantly "moving" through time, I write "moving" in quotation marks because time and space are two axis of reality, but not the same. Anyway, you do point to something so obvious that many times we forget it is real.
Focus on a surton specific event in time than try to visulaize it like you there and than focus on the details!try to be compleetly in the moment and look around
You’ll get more value out of death
Lawrence you are in my head. All of your videos have plagued me all of my 45 yrs. Thank you for sharing your journey with us like minded people. But it is all consciousness, there is no thing else.
May I ask, how you know that there is nothing but consciousness? Seems a bold claim when the scientific method seems to tell us there is a physical reality independent of human perception.
@@sirkamyk9886 a reality created by consciousness.
It's not all consciousness. There is baseline reality but it is forever out of reach. Each consciousness is an attempt to interpret reality and the scientific method is the best we will ever come up with. The scientific method and mathematics is an approximation of reality. Both are systems designed to guide our brains to try and understand what all this is, but us being trapped in our own senses, all our attempts will only scratch the surface of baseline reality. Still awesome. Life is life
We need to understand what time isn't, so we can narrow down what time could be!
The more I try to understand time, the more my brain hurts...
Do you mean like a process of elimination.
I'm not a mathematician, so that language is beyond my scope, but having listened to many physicists explain time and space in their own terms, Lee Smolin makes the most sense to me. He doesn't have a final answer, but his explanations comport with my own uneducated view of space and time. It's comforting to know that there's someone out there in the field who is respected and who has come to see that my view of the world is quite possible from a scientific perspective. If you'd been laughed at as many times as I have by physicists or had gotten those glaring stares as much as I have, that means something.
You just got another laugh.
One of my favourite channel on TH-cam!
BTW - Kip Thorne’s articulation of relativity was masterful in its simplicity and clarity.
But be aware that he was trying to make sure that lay people would understand what ge was saying. The _real_ theory is more involved and requires at least perhaps one semester for you to grasp. For example, when he says that the speed of light is the same as measured by observers moving in any way. That's actually an oversimplification. The observers must be inertial.
@@User-jr7vf thank you and as a businessman interested in this subject, I appreciate Mr. Thorne’s efforts to help viewers comprehend what is he saying.
This podcast is truly outstanding. I so appreciate professor Kuhn's intelligent explorations of the thinking of the best minds.
I have the feeling that I am always "here" and always "there". I could take you to the exact location of my 5th Birthday and I think I am still there in time in the everlasting "now". All time exists in an eternal now.
Or rather, time does not exist. It's the way matter behaves that make us perceive the illusion of time passing by.
@@staffankarlsson1428 if there was no space time would stop; if there was no matter there there would be no clock to notice it had stopped.
There is no real time outside without human awareness.

Thanks for these videos. I'm not a Scientist. I'm just a regular person with many questions and a thirst for answers. Your quest to find answers to my difficult questions is commendable.
I'm not sure if this show is taking me closer to truth or closer to head explosion but i love every episode. Thanks!
Me 🤯🤯🤯🤯 but I still try lol.
I really wish Robert Lawrence Kuhn would interview me on these topics. I have ALL the answers!
I think time being emergent is a very simple and coherent theory, and it ties well with the simplest theory of personal identity. We feel as if time exists, and that is because we remember our past but not our future, and we can differentiate between 1 second ago and 5 seconds ago, that is just the way our brains evolved. There is a certain order in which our mental states occur, from past to future.
There is no reason for this order, or for time to be fundamental. It is a useless ontological commitment. We experience things in a certain order, which alligns with classical laws of physics for a simple reason that those classical laws were developed by information processing system which works in time. So you measure ball's velocity at t=1, then t=2, then t=3 and so on. You don't measure it at t=3 and then at t=1 and then at t=2 and then try to develop a set of equations that would support such evolution in such time, it is not evolutionary benefitial at all for us to have such method as even somehow intuitive. Imagine knowing just all the states of the ball without knowing the time, you can try developing laws of physics for each possible ball-state combination, and you will likely find that the simplest ruleset is the one that describes the evolution of ball-states in the same time we experience. This is because our brain is an object, just like the ball, and all the information processing in it is more likely to occur by the simplest ruleset which is the one that matches with the order in which we experience things.
Here is my argument: I can imagine such a bundle of ball-states that the simplest ruleset explains a certain succession of those given ball-states does not match with the simplest ruleset that explains the succession of states of the information processing system that is studying the ball's movement. Time is the order in which information is processed. There is nothing fundamental about that order. It just happens to allign well with everything else happening in the physical world, for reasons described above. It could be that it does not allign, although I am sure it is mathematically very unlikely.
So the picture that follows from this: there is a bundle of mental states. Those are experienced in a certain succession, each of them feels like it occured after the previous one. This succession is emergent.
I actually have a very simple argument for that order being emergent. Let's suppose it's fundamental. If order is fundamental, t1 t2 t3 is different from t3 t2 t1. Let's say t1 is experiencing rock flying into the window, t2 - rock breaking the window, t3 - aftermath. t3 feels like continuation of t2 and t1, because it contains memory about those. If you reorder the mental states so that t3 is the first, t3 still contains the memory of t2 and t1, it still feels continuous with t2 and t1. And t1 does not become such that it contains the feeling of being continuous with t3. Reordering the mental states did nothing, as the contents of those mental states didn't change. The subject of the subjective experience realized in those mental states will experience the same thing regardless of the "order" of his mental states. Given that, there is no reason for an ontological commitment to the existence of any specific order as it does not make any difference.
I like the argument. I will add that the emergence floating in order does give rise to importance. I don’t see how it can be irrelevant.
Or put more simply,
time is a concept only and
this concept is vastly more convenient than
talking about the relative movements of different objects.
Physics and philosophy seems so the same at that level. They can say whatever they want and everybody will listen in awe.
The way the audio repeated at 8:46 as they were talking about how crazy time was...had me thinking I entered a time loop
🤣 But the audio didn’t repeat, it’s just that they were excited.
"what do you feel?".... You can see the real enthusiasm and struggle on Robert.
The way some of these guys, like that Nima dude, will just rattle of facts and figures related to concepts and principles like Plank length in a "of course everybody knows that," sort of manner always blows my mind. It's not done in a I'm the smartest guy in the room kind of way, it's just how they roll. His stream of consciousness is vastly different from mine that's for sure.
It takes time to get closer to truth
I believe this is this is the closest.

Knowledge and understanding is the most precious gift. Mr. Khun’s contribution in bringing us all Closer To Truth is invaluable; respect, kudos and sincere appreciation to him as we continue to follow him on our journey of discovery. This respect comes all the way from Hong Kong 🙏🏼.
God created time and is outside time hahahahaha thank you Jesus.
By the way I believe Robert was saved and is with the Lord thank you Jesus hahahagaga the joy of the Lord is my STRENGTH HAHAHAHA 🙏
Very beautiful videos thanks .... worth millions and millions of love
Its Such s treat being able to listen to these conversations.
Fantastic as usual
Loving this channel.
Its good but the delimma is that only one can know truth through personal experience but i love this show.
I love you
One of my absolute favorites!💯🥰🖤
Same!
What Robert is doing is truly amazing. Seeking the truth in the mix of solid science and biased beliefs. There is no consensus on time no matter how successful are theories backed by empirical evidence. And to put ot simply thete is no time only abstract clocks conveniently located wherever we need them. But scientist don't like the mystery to disappear so they keep supporting mythologies.
One of the best episodes. Congrats Robert! I would have asked the very same question about the existence of the future in block universe... 😊
Pleasure overload.
I think time is as real as temperature is. Nobody talks about if temperature is "real".
Temperature is familiar to our senses we can feel it. Time isn't familiar to any of our 5 senses, it might feel like it's passing but that isn't a literal feeling. but rather psychological.
One of my best episode, thanks !
Time is natures way of preventing everything from happening at once.
I just love kip Thorne. Genius mind
when i was very young maybe 6 years old and i was told to wait 5 minutes or 10 minutes for something i would look at the clock and man it really felt like forever. and people would say thats because your young time will go faster as you get older implying that its a figment of the imagination. But as i am learning these things i realize now that it was not a figment of my imagination time really was going so slow for me and that it most likely has something to do with my size that i was was much smaller in relation to the earth then adults. and then it all made sense. on a side note its nice to know we have all lived a life time no matter how fast we die. and imagine how long time is for a microscopic organism. when i was real young it felt like the time would never come that i die but we know that it will come. so all that matters is what lays ahead and what is out there in space and beyond our dimensions even. when you think about why anything at all rather then nothing at least for me i am understanding that its because it had to be and most likely everything had to be and there is no such thing as nothing.. in fact that is the meaning of nothing, that it don't exist. so don't worry you are here and will always be here.
Nothing is when we did not measure or practice. Can you practice or praying "infinity times" a day and to be realistic you have to measure to be specific for example by praying "five times" a day with reference to nature days and nights , direction and purpose to be real and acceptable in mortal domain. Else non existence and meaningless when in immortal domain. We don't know because we did measure time but lacking of practices or experiments or level of 'infinity" dimensions missing except TIME, GRAVITY, ELECTROMAGNET, WEAK and STRONG NUCLEAR FORCES. Be prompt in doing good deeds (time is real and measurable) by turbulence which would be like a part of the dark night (time is not real and cannot be specifically measured.) During (that stormy period) a man would be reality in the morning and an not real in the evening or he would be a reality in the evening and not real in the morning, and lost his "faith" from something real into nothing for not measuring and be specifically good. Something good and true will be rewarded real and vice versa.
Got lost in there but since my brain organises my life around space, time and cups of tea, I managed to find a way out of the maze and survive and i feel ok again...😉🤔🤕
💛🤍💙💚👍
I sometimes look at books that I have read, or even stacks of books, and think, "All of that is in my head."
With the way brains work, only parts of it are in your head.
Your brain has to make room for many things that are important, like memories that are important to you.
It's common misunderstanding that it is possible to go back and forth in space. Matter defines spacetime and when you are moving forward then the space behind you is not the same space - there the defining matter has been changed - you can never go back to the past position but when you imagine you turned back, you only turned the direction where was the next forward direction. Space and time are really equal.
I would postulate that time is emergent from space and that no space is impossible (a vacuum is still a space with feilds.). Our brightest minds are experts at rationalising, analysing and justifying any point in or about our Universe.
Time--The absolute unit
All it takes is one curious human being.Dear author thank you for genuinely being curious and putting out all the knowledge to the world.
Space creates time!
love this show for along time BTW. im pausing it and going over it again and looking up definitions.
It is real that time is a concept of the rate of motion intrinsically from each heart and mind.
Beautiful work as always 👏 Boy, I wish we knew the truth about time, it's the topic that intrigues me the most
Maybe you wouldn't like the answer.
I don't have the words to express how I love that show. I need more of that great thinking presented here. Thanks, happy Christmas to all of you.
All I can say, it's about TIME ~ !
kuhn's face when the guy says 'two axis of tome', so good. same here :-)
Thank you! I can sense my conceptual horizon expanding as I watch your videos. (The word gravity leapt to my mind a few minutes before one of your interviewees brought it up.)
I really enjoyed this one.
Pure mental bliss
Every one feels time no one knows time.
I like the way the first guy describes time, he's getting closer to the truth. A time traveller would be able to master skills at seemingly superhuman speeds wouldn't they. because they could simply spend hours practicing and then return to the point in time where they started learning and look like a genius. If someone could manipulate time that would make them invincible next to those that couldn't. They would know things they shouldn't know. They could have entered a room heard a conversation, then gone back in time and never entered that room and still known what was said leaving the occupants wondering are they guessing? they couldn't possibly know that could they? Think about it, I wouldn't mess with a time traveller, neither should you.
Great advice🕎🕎🕎🕛🕛🕛
Nothing but the intervals to which we attach names: hour, minute, second. Einstein demonstrated in 1905 that time does not exist, its only valid expression is as a variable.
Hurray..you also know this!!!!
As is everything in the matrix in which we interface with; name and give meanings too, to what we we perceive. And has been preformed before our time of being. As there is no duality because we are all as one with the universe. consciously connected, yet unexplainable.
I am a simply a devotee of your curiosity and lucidity.
Beautiful!
Great episode. All that in 26:46!
Great episode.
Two axes of Time... that's my mind blown for a week or two!
That's such an interesting and damn good question
what lee smolin said was very interesting
Time is a loop, Perfectly spiraling out and back in to itself.
It’s always amazing that so many smart people presupposes that it’s time that’s the illusion and not our perception. Having different perceptions of time doesn’t equal no Simultaneity. The firecracker appearing to fire differently to the observer tells us nothing about the true nature or the reality of time.
4:18
Strong parallels with children or grandchildren. As a parent, you are constantly sending information backwards in time in a sense to avert disasters but never being able to realize that world for yourself. You try to give them hints and advice earlier in their youth than you understood that information in yours. Their reality is a split dimension of what yours could have been.
I believe time fits better as an emergent dimension, not a fundamental one
th-cam.com/video/FDYPQIJY14s/w-d-xo.html
Really good!
That was such an intense episode but so good 👍
i always intuited that the future is already there - so that is how some can foretell events
Time is contingent on individual perception. Blows your mind to try and conceive it.
th-cam.com/video/FDYPQIJY14s/w-d-xo.html
Time is contingent because Time is a concept. Only.
I can't wait until he writes a book with all the knowledge he's been collecting

LOL it's too much information ha ha. He has talked to all the smartest people! I hope he just makes a video set ... the whole world has a chance to view
Phenomenal
Makes my mind wander and even believe i can solve time travel 🧳🧭 😂😂 love it
Since the space and time are relatives and everything exists in spacetime can be reduced to information that is perceivable only by consciousness thus fundamental quantities must be consciousness and information("knowledge").
So minus SELF one can perceive it.
Our consciousnesses can reduce things to information but that does not imply that consciousness and information are fundamental.
@@Hank254 After millenia of reasoning we still do not have the slightest idea what consciousness is. The reason for that could be very simple: it is fundamental. You can't see the forest for the trees 😉
@@djgenetic111
What you are doing is called an 'argument from ignorance', it is a type of logical fallacy. You don't get to admit that we don't have the slightest idea what something is and then proceed to draw conclusions about it.
Mat made a statement that since everything in spacetime can be reduced to information, it must be fundamental. I am saying that does not follow, it is not a good reason conclude something is fundamental. I can take pictures of things in spacetime too but that doesn't mean everything reduces to pictures.
If someone wants to claim that consciousness and/or information are fundamental, they are perfectly welcome to demonstrate it.
@@Hank254 Check out the work of Donald Hoffman, it's really interesting.
Thanks
When you interviewed Kip Thorne, you should have asked him about his fine collection of vintage CRTs.
So time is conciousness
If you mean that
time is a concept maintained in the minds of some conscious people then
I agree with ya.
Real about time is both the potential time + the realized time.
Listening to the different views of the last two physicists - from my lay perspective - seemed like the Pre-Socratic philosophers Parmenides and Heraclitus all over again.
There is no time...only now....our identity is a constant always present in the now...so its a I AM...think about a "past"event and you relive it as though you are experiencing it...same with "future"...I want this type car is only because youve experienced the feeling of owning it as NOW..thats how we get goals...in.my practice I helped most people to stop reliving past experiences..im a clinical.psychologist....ive not had a watch or clock for over 30 years and ive never been late...stop thinking time and your internal watcher keeps you always "on time"....we only move through events..seasons...but ALWAYS as me now...the eternal I AM
Wow Lee Smolin just dropping a truth bomb over there
Time is just the freedom to move
Time is measured causality.
Whats real about time is that I never seem to have enough time.
Events may come and go, they may emerge , be simple or complex, be reducible to something fundamental.time cannot.
Time is neither an event nor a thing. It is a unit of measure between events like distance is a measurement between positions.
I think time is just a collection of single moments. Nowadays I can continuously take fast snapshots with my phone as I'm moving. If i were to take all of those images into my movie editing software and make each frame as short as possible, i could almost create the illusion that it's a video and not a collection of images.
Maybe the Universe is expanding into time itself, rather than both time & space on the run into an endless void. That would mean, what happens in 10 years from now is already predetermined, it will happen, because space will catch up to that moment of time. The smallest measurement of time is Planck length, but that's only because we can physically measure it. Any measurement of time within space is possible, without space, it's immeasurable. Impossible isn't the word, you can't exactly measure infinity.
Closing was closer to truth
I feel same Sir🇮🇳 time is illusion Sir🇮🇳
I'd love some new episodes if that were possible once this pandemic is over come on Robert you can do it
He's likely to continue as he's been doing this for 30 years.
Could be that time is actively shaping physical reality. When perceive time, perceive different effects on physical reality that time is shaping.
I wonder if we as humans even have the perceptual and intellectual access to reach the true answers. We might be limited by perception in a way we cannot even conceive of, so reaching a full understanding of the nature of reality may just be like trying to cut your way to the end of a mobius strip try to get 2 pieces.
Time is as real as the human mind can make it
Sure these are super interesting questions, but thinking about alternative universes and realities is no more than a mental fun exercise if we can only exist under the constraints of our current world. Even if these ideas are true, they end up being unimportant for practical purposes.
How about this for possible practical purpose?: What if our life depended on it?
What if the existence of earth and the existence of earth in other dimensions were threatened by our nuclear weapons or volcanos.
What if these create a rip in one of the matrixes (or sponges?) of space /time/gravity dimensions?
UAP occupants or motherships, are trying to warn us telepathically from the future! They are reportedly sending 1’s and 0’s through to pilots, who write the messages down in 1’s and 0’s, according to Prof. Linda Moulton.
This is why full disclosure is not happening on UAPs.
The warnings are “to advance quickly” to save the planet, but not listen to the governments as they are beholden to “others”. Who are these others they speak of?
Should we be rushing in building an understanding of any laws of the multiverse, for this reason, so we can save our planet and ourselves?
If we have a such a minutely sensitive microscopic and macroscopic multiverse like a multi -layered sponge cake, with tasty subjective time filling and sweet absolute time frosting, then how about those who do, explain why we would even think about surrounding this deliciousness called life and time and space and consciousness, with nuclear weapons and climate heating? Why again?
@@kerrynicholls3435 Well, it seem to me that you are off to a great start, now write the equations, run the experiment, collect the data, write the findings, add a discussion of the practical applications and submit the paper for a peer reviewed publication. That would be a great next step.
What in the world am I missing here? Isn't it obvious to everyone that time is a human construct to organize our lives and that it doesn't actually exist whatsoever in the universe. Time is just simply reality playing itself out in the moment where existence lives. These people are batshit crazy.
*Correct* An overlay of the self as thoughts projected on to the world around you; quantum > quantifiable (countable ) hence about anyone loses it contemplating infinities if they do it right as most human mind needs finites to get ahold of something - quantum creates a "field" which is the commonly grasped Space & Time ▬ You can be sure that it *Isn't it obvious to everyone* though they do occasionally sometimes go non-finite for a moment might be 0-1-2-3-4-5.....events in a lifetime which is immediately blocked out due to the elephant in the room phenomena
Intresting topic just the other day I said time can be manipulated I hear you !
What's real about time? I'll tell you in a moment...
The two times axes universe intrigued me. Tell me if this sounds like a reasonable objection: the argument here is I can imagine a universe where there are two axes of time yet that would bring up many paradoxes, break causation, and is also inconceivable by us. But it is possible. Why think so? If you say that something is possible are you not supposing that you logical faculties find no contradiction in its existence? Thus, when you say something is inconceivable are you not saying that it lacks internal mental coherence? I get he is trying to argue a deeper point that it is but beyond our mental function to understand. But that doesn’t seem to be what is true. For the idea of several time axes is developed in the mind, then we ask ‘can this exist in reality?’ The answer to that question will likewise come form the mind. Therefore, in both cases we are presupposing our mind’s rationality has external usage. But if you then say that I suppose an idea which I know via my mind, then propose that the idea is paradoxically to our minds, then suppose that it is a possible idea external to our minds, are you not still supposing that third idea by your mind? Therefore, there is a contradiction in these premises. Therefore, such a universe cannot exist if we are accepting the efficaciousness of human cognitive faculties to not only apprehend rationality but also that said rationality is applicable to the metaphysical landscape. Of course, this assumption cannot be denied for to deny said assumption is to accept it. For you are still saying that the world functions in a way external to you and you know the way in which it does function. Namely not in accordance with your mental function. But that’s a mental function.
In short, time is a concept only.
13:38 his analogy using the book to explain block universe was fantastic..
I believe similar, except I think there are an almost infinite number of remainders to the story, each potential until the page is read. Think of a book that gives you the opportunity to have free will, and to an extent, choose how the story unfolds.
Try imagining that there's no such thing as time. I mean try seriously hard. Then look at the stuff around you and at the universe and see that nothing has changed. There still be stuff and it still be moving at which point you might realize that 'time' is not more than an extremely useful concept making it much, much easier to think about how some moving things relate to other moving things.
In short, existing things don't need 'time' to prevent them from popping out of existence.
re book analogy - with a book - we can easily move flip back to previous pages - or flip forward to "future" pages - how do we do that with the block universe - outside of scifi
@@REDPUMPERNICKEL - if time stops - and everything freezes in place - how is it still moving?
@@johneyon5257 "if time stops"
Time cannot stop because
time is not actually existent.
Nothing freezes in place because
everything that actually exists
is moving with inertia.
After a lifetime of thinking that
time is a something,
it might take a while
to realize that it's not.
Time is a concept so ubiquitous in our language that
we are no longer conscious that when we speak of time
we are really only speaking about the relative movements of objects and
we speak this way because it's more convenient and efficient.
You know with great certainty that
there is no delicate antenna in a clock
being induced to oscillate by a flowing river of metaphor.
And you know there's a reason why the mechanism at the core of every clock is called a 'movement'.
@@REDPUMPERNICKEL - i see - - time is an illusion - it is confused with changing relationships - which are real - but time is not - - that could be viewed differently - that time emerges from changing relationships
Couple of questions: (1) how is believing in the Block Universe concept different from believing in destiny/fate? (2) The Harvard scientist talks about gravity as though it is independent or separate from Spacetime. But I was under the impressions that gravity _is_ spacetime; didn't Einstein say that gravity is simply the physical manifestation of spacetime! curvature? (3) how can we think of gravity and quantum mechanics at the same time? (I know.. that's the unification that great minds have been/are after). My question is, to talk about any meaningful existence of gravity, don't we we need massive or at least a substantial or significant amount of mass, which quantum mechanical entities just do not offer?
"All the phenomenal world or universe is simply a Mental Creation of THE ALL, subject to the Laws of Created Things, and that the universe, as a whole, and in its parts and units, has its existence in the Mind of THE ALL, in which Mind we live and move and have our being."
-The Kybalion
How do we know if time flows/moves?
It doesn't it's events that flow/move time just tracks and measures them.

What's real about time is that it passes and I am getting older
Actually it's just days and years passing which are a result of our planets rotations which are what our clocks and calendars are synchronized to which in turn converts these passings into time passing i.e. 360 degrees axis rotation = 24hrs and 360 degrees orbit of the sun = 365 days. Ageing is a consequence of telemore deterioration, this process is merely measured by time.

It can be *both* absolute and relative, *both* flowing and all there. Just treat the two versions as different dimensions and coordinates, treat *all four dimensions* of space-time as itself flowing in time. The coordinates of space-time being (x,y,z,t), and of absolute time s. In Minkowski geometry, the proper time fits that bill. The line element for the Minkowski metric, written as a proper time metric is: ds² = dt² - (1/c)² (dx² + dy² + dz²). Throw in s as a coordinate and write the line element, instead, as dx² + dy² + dz² + c²(ds² - dt²) = 0. That's the light cone of a 4+1 dimensional metric (a de Sitter metric). The t-time is "all there", the (x,y,z,t) all "flow" in the s-time. There you go. Problem solved. You're welcome.
Oh wait. There's more. The "time dilation" (s - t) has a *non-relativistic* limit too! More precisely, the coordinate u = c²(s - t) continues to be perfectly meaningful, even in the limit c → ∞. Substitute it in the line element, before taking the limit, and you have (1) a quadratic line element dx² + dy² + dz² + 2 dt du + (1/c)² du² = 0, and (2) a linear line element for absolute time ds = dt + (1/c)² du. That geometry, or a derivative of it, is used in 5D cosmology; *specifically* to bring forth an "historical time" dimension (s) alongside coordinate time (t).
Take the non-relativistic limit and you have (3) the line element dx² + dy² + dz² + 2 dt du = 0 and (4) the absolute time ds = dt ... which shows how and why the "absolute time" = "coordinate time" conflation originally comes about: it's a holdover from Newtonian Physics. This geometry is called the Bargmann geometry. The symmetry transforms that leave its invariants, (3) and (4) fixed is called the Bargmann Group - which is today recognized as the *correct* symmetry group for non-relativistic theory, rather than the Galilei Group.
The Correspondence Principle states that a new paradigm should grandfather in (and provide Relativistic corrections for) *all* of the old paradigm. The newer understanding of the old paradigm (Galilei being lifted to Bargmann) means that the other end of the Correspondence Principle *also* has to be lifted: the symmetry group of Relativity (which is Poincaré) has to *also* be lifted - along with its geometry - to one for the invariants (1) and (2), rather than for Minkowski geometry. So, not only is this a way to incorporate historical time, s, alongside coordinate time, t; it is *mandated* by the Correspondence Principle, applied in reverse, to accommodate, reflect and match the newer increment in our understanding of non-relativistic theory. The old paradigm informs corrections for and increments on the new.
I agree
Clock is just a measurement of time. We do not know what Time IS, however
