Taking into consideration the fine atomic structure to a thing and clearly a variety of other factors. The thing would merely be the same or different to another object of its type or particular. 🙄 Therefore while our clocks might say 2pm relative to the observed speed of light to the Sun overhead. In reality? We don't know because..... Of that one enny tiny wittle problem. About "Outrunning one's own light." Proposed by Albert Einstein. Okay... Speaking of which! Look at the time!

Definitely not the one he uses. Time is absolute, immutable and the way which we track the motion of objects and energy through 3 Dimensional space. Your perception of the speed of time may change depending on the environment you are within (a second for me might be 2 seconds for you for example) but you cannot change time itself or the past. The Trouble With Time on IAI with Kaku, Elitzer and Maudlin is a good episode on this subject matter.

Speed! I didn't even think about that. What freaks me out about the perception of time. Is like for example when your 10%. Just barley enough to precieve an alarm clock. You can think of so many things in under a few minutes. It's insane. Or sometimes ill be driving. And get so caught up in thought. It feels like three hours went by. But you look down and it's only been 5 minutes. Then afterwards like. The frontal lobe of your brain is fried. But sometimes it gets really bad. And the thinking will spread from the front to the back then to the sides of your head. Till eventually you come to a resolution about what it is you were thinking about. And it releases. Your body cools down. You feel peaceful at last. You feel happy. See things differently. It's like getting a physical workout but not. Idk.🤔 It's like as if your brain is adapting or evolving to some unseen force in real time. I wonder what that could be? Don't other animals sense like sonar and shit like that? I mean it gets scary as shit sometimes. It's illusion becomes reality. There is no "time dilation" between your perception and the cause of events. Or very little to almost no time dilation between events. You can literally sense things before they happen. Absoultely fck-ing horrifying. It happens to me about every 4 years. My brain does this blue screen reboot stuff. (To draw a computer analogy) I call it the state of One. The state of One is terrifying. You litteraly have to do basic arithmetic to get out of it. 1 2345 10 20 100 so on and so forth. Till you get idk "numbers" back. That puts the distance in between you and causality.

Adding to what time dillation is I think mass is computational load of given "cell" of space. That's why mass curves space-time. Singularity would be a state where more computation is being "queued" each step than can be performed. Because space is causally linked it creates gradient of computational load hence gravity.

Even if you reverse a liquid to vapor and back to liquid , time doesn't go backward. The fact that we fluctuating between phases of states but maintain structure for extended period of time.

“Even if you phase change-time doesn’t reverse.” The problem with these sorts of statements is that they are all referring to different processes and calling them all “time.” One can reverse one’s spatial direction, but just like your phase change example, it’s only a local reversal and in fact you’ve not reversed anything globally. Another problem is that people always assume time reversal doesn’t happen but it could very well happen constantly at various scales.

Good old Steve Wolfram, everything is a computer operation to him. As they say, if all you got is a hammer, the whole world looks like nails to you.

What comptutation is implemented by moving? It seems that the location is updated in continous movement. The distanced to other relative locations also are updated, and momentum, velocity, mass, and wide dimension measured parallel to the trajectory.

""" A time is the days of the week and HHours of the day . Time going slower then You save a day past week """

Time must be related to the speed of information and the rate of information processing. It takes less computation to update a spatially fixed state than a moving state. That is, if the computation rate in our reference frame is like "tik-tok-tik-tok...", the rate for some other frame is "tiiiik-toook-tiiiik-toook..." 👀

That time dilation is a result of the overhead of the computation of recreating the object in space is a pretty wild stretch. That time dilation (and the original thought experiment of the moving clock) is anything other than a rate of change of simple latency is an even wilder stretch. The ultimate stretch however is that the act of observing a clock to tick slower because it is moving away and its visual signal is undergoing the rate of change of latency means that time will move slower for the observer.

@borzydar1196

The way I understand Stephen Wolfram's theory time and space would be discrete, but really high resolution. Each step there's an update of state. When you're not moving at each step all your processes are updated, but with movemenet some steps must be wasted on translating you through space, the faster you move the more steps are necessary to update your position. At the speed of light all steps would be used to update position making you basicly freeze in 1 state. Because your consciousness is bound to your processes you'd simply observe everything speed up.

so - in effect- every time we move, even minutely , we also move ahead in time. The faster we move the more computational power required to recreate a new you in a completely new environment(aka universe). So creating this new environment rather than just adding on to an old environment logically requires more computational power and hence the trade off is time moving slower as computational power is finite and there would have to be a trade off either in time or space.

Hang on a minute. Motion is relative. Consider 2 people moving relative to one another. Which one is doing the computation?

So wave particle duality and probability distributions thus no waste of velocity or displacement yes? If we are to account or require computation we must account for decay yes?

Uhhh, like, what? Uhhuuhuhhhuh.

"Time" is a pure human invention deriving from observing the Earth´s rotation and annual motion around the Sun. ---------- Extrasolar objects moves by differerent velocities and orbital motions = "Time" goes differently there. Celestial objects are orbiting a central object = "Time" goes in circles. There is no "time dilation" at all, only different velocities of objects.

If i may ask Dr, can you compare time and space directly with the electric and magnetic force, where the electric is instantaneous which delivers the time parameter, and the magnetic delivery motion? Seems like both sides of the same coin.

Ok, from a computational point of view of refreshing/maintaining an objects form/existence as it moves, seems a reasonable posit if the universe is cosmic computer.

0:59 ok. Why is it not true that the computational energy effort to create motion would not then have a natural by product of time? If so does this still add up? Or maybe this is what he said but I heard him frame it as individual events initially then say some energy is spent on time while in motion but less so. Why is it not an equal amount as a result? What makes it less so, are they not bound? I think, maybe, time is a by product of physical motion. Light and sound waves are “gifted motion” in a sense (from?) and so are able to move through space-time/ time-space differently (entirely how ever a direction or no direction at all can occur which is similar to motion but I think might be the other half of it, the reflection of it. Everything has a yin/yang, balanced counter part to it) than other types of physical matter. .. Entropy is, or, might be too broad a word, I don’t know of a new one to use), but my thought is entropy ought to be attached to physical matter and the non physical matter has a different idea for the way in which it changes form from its initial entry point of observable/detectable existence. It’s own term for entropy. Motion is the sustaining of physical in some degree. Other events take /use motion to breakdown/digest discarded physical events. Like decay. So, time exists as a by product of motion, right? If yes, somehow, then doesn’t it need no computational effort? It’s .. similar to exhaling a by product. There is effort yes but it’s a consequence of motion, intention, of things in the body functioning and the value is the inhale and exhale to inhale again the life sustaining properties of air to a body. There is likely a better analogy than that but since this is a comment section on you tube and I feel slightly like some one, if anyone, will a respond in a condescending sociopathic way why think too hard on it. Just because a computation can be done, a mathematical determination of explanation and it is all checking out, did you move through time and not space? Sure, likely so. I sit and think and in space I can observe and with basic math skills if need be, determine I did not move in space. Yet, I can still observe decay. Because I am witnessing a thing, this is .. moving through space? So, just to take it back to the top, what I was only meaning to say is that if it’s about time or motion then one is the event of the other, it seems. And like a breath and living as a result which means I need to exhale to do so, time requires motion and if you want to bypass time, like how other wave forms can do then you need to disregard space as well. Ok, so .. quantum entanglement except someone caused the corresponding entanglement particles to be in a location in space in order to claim this event occurs by physical observations in space which means time and motion. .. so if one wants to bypass it all, they have to discard anything bound to motion/time. Or utilize the initial force of whatever light/sound uses. It’s sort of like, asking something in the 4D to do it for you or have access to a propellant and a doorway/rift.. whatever. This is really why anyone cares about quantum and thing, right? Time-motion-space. Then.. but not really. Because you can’t have any use whatsoever for any of it when you don’t apply the laws of entropy as in you don’t care at all about time when you are not bound to it. So, one wants to discard the rules of a thing but also wants to maintain the rules of a thing simultaneously but to what end? The very rudimentary view might be all the uses of saving lives and knowledge from other concepts of time/ timelines/planes of planets/existence. All of this involves the laws of physical ness as we know them. All of the things we imagine in science this was is about being alive as we are. All the results we can think we are working towards remains in the physical experience. So, what is the point of trying to circumvent or discard the rules? I think we, maybe, if we solve for the actual reason we think it pertinent to do a thing to not do a thing then.. we would have it solved for all of it. Most likely, it’s just because it sounds fun. For those of us who don’t live a life in a servant status to ..our lives, anyways. If you stop motion? Do you stop time? If you stop time can motion still occur?

The computational thing sounds good but what is "a (fixed) place in space" in the first place? Let B and B' two bodies moving with respect to each other at a constant velocity with an absolute value v. Let's define coordinate systems, Σ from B and Σ' from B' so that B' moves in x direction of Σ and B moves in negative x' direction of Σ'. In Σ, a fixed position relative to B is a place whereas a fixed position relative to B' isn't; in Σ' it's the other way around.

Julian Barbour called it a while ago, he just didnt use the word 'computation' a zillion times.

How does this relate to the fact that motion is relative? Computational effort in moving vanishes when you go to the reference frame of the object that is moving. How is that represented in the graph? How do you change reference frames in this new physics?

I always pictured it as if we are always traveling in the speed of C, but in the direction of time. And when ever we travel in any of the spacial dimensions, we take speed away from the time direction and apply it in other directions. In addition to that, I have been hypothesizing that maybe there is some singularity at "the end of time" (at least in the future) that is drawing us in, like a gravity well but in the time dimension, thus explaining why we are fixed travelning in one direction of the time dimension. One could describe it as if we are in some free fall in the time dimension. One could picture it as falling to the surface of planet earth, but the direction "down" is instead that of time. Photons that travel the speed of light, it is like they are orbiting the time singularity, thus becoming timeless.

I mean... sure, that is a perspective you can take. But it doesn't really cause anything to be different. it's just another way of looking at it. The math works out because it's not arguing anything different.

Well, Brian, obviously Wolfie’s attempt at rewriting quantum mechanics is happening on an “abstract manifold”, as you put it, of some kind. This manifold *better* have at least a symplectic diffeomorphism of some kind (at least in the quantum physics sense of symplectic), or else some result(s) or other derived from Wolfie’s space would be incorrect (with respect to QM). [I’m sure you can see this.] But much more amusingly: “Time is this inexorable process of executing computations.” (says Wolfie) How fun. Consulting at Thinking Machines may have had subtle but distinctly definite effects on his thought processes.

Time depends on how much "acceleration" there is. The less acceleration the faster time passes by as well as the less contracted distance is both of which contribute to change the observed speed of light across large distances from our particular frame of reference.

Time is only a human concept! Time is not a physical reality.

Wolfram's ideas are attractive initially but after thinking about it more deeply his conceptualization of time doesn't make sense to me. 1) why are we assuming computation has to be sequential? And 2) if time is not an independent and external dimension how can we ever think about durations or variation in changes between computational states? And 3) do we have to assume time is uniform and that each iteration of computation is a time step? And 4) the idea of changes between computational states has time implicitly built into it, so this all seems very circular. We not only don't have language to talk about this ( we cant speak about speed or durations), but I'm not sure it is helpful without a major overhaul in how we think and some idea of how we can deal with relativistic effects. Or maybe I just don't get it? Also if time is how he defines it, and motion requires computational effort as he says, how can these things be independent and how can there be a tradeoff??

Now maybe I can describe the situation with this subject. Quantum coupling/Quantum entanglement (Whatever) is what I was describing. An instantaneous transfer of information (Pressure, Temperature, Motion etc) over a distance of 3.3 meter/10ft. That is what I experienced. Know it is just a story yet if Dr Neil De Grassa Tyson did transfer the descriptions of the "Fights" One should be able to realize the something "Odd" is going on.

Time dilation is a mistake and it comes from the delay of the communication signals in satelites for example. Why would there be any time dilation? There is no logic to think a time measurement device would go slower regardless of the speed it takes.

I remember “tracers”😂

What is calculating then, and what is the computer!?

Pauli exclusion principle connection. Bought a few (Quite) books

Einstein's-Lorenz Special Relativity (SR). The theory at the core of all physics and which nobody seems to get. In a nutshell; The speed of light staying constant regardless of the speed of the object emitting it, means frontal space and time must be contracted by the speed of the object. So the speeding object simply encounters less distance and less time as it speeds. Einstein quickly realized that a contraction of space and time seems awfully close to the effect of gravity. But not quite there yet as it missed the acceleration effect gravity has. And he was puzzled by how this could apply to rest mass exerting gravity. Notice this was before the Rutherford atomic model, suggesting high speeding subatomic particles. Had Einstein known this he, would have understood restmass is the collection of extremely high speeding subatomic particles moving in all directions, hence causing the exact same SR spacetime contraction effect but now on a radial scale. At this time Einstein needed more time to get to a better theory. He threw in some decoys to prevent others to understand it before him. He was very careful not to mention frontal 'spacetime contraction' , so he invented the weird terms of time 'dilation' and 'length' contraction presenting them as two separate things, while he did promote Minkowski spacetime as a unit. Notice the inconsistency please. Academia until this day blindly follow this weird semantics, avoiding the more correct term 'frontal spacetime contraction'. Thus avoiding the key to understanding gravity itself. words matter. If we stop using the unhinged words 'length contraction' or time 'dilation' but use 'frontal spacetime contraction' instead. We are on our way to understand gravity. It then only takes the admission the inverse spacetime results in the objects relativistic mass (inverse time) and energy (inverse space) with its orthogonal virtual counter speed -J/Kg or -m2/s2, and we can close our epic 100 year long quest to understand gravity. We were fooled. thats all...Find technologies (BEC's) to align, condense and next steer god-given 'free' subatomic speeds and off you go....

Err- Hm. This is a computational analogy; the math is working out by semantics of simply referring to energy as "computation." But computations are not literal to physical events in which motion does not require computation to happen as in a simulacrum, rather, actual physical energy input of the objective & absolute sense. The illusion of quantum local non-reality is because quantum mechanics overlooks the fact that its fluctuations are literal, reified motions of spacetime itself. So at relativistic scales, the more physical energy put into something, the more inertial mass it gets, thus the harder it is to accelerate it faster in spacetime, and the more it begins to become a singularity in its own right. The more energy is put into something, the more quantum wave functions there are collapsing toward like kind of that energy; which ultimately must include its original property of being at a fixed point in the past. So space itself compresses in the direction of travel (as traveler approaches becoming singularity), and time slows toward a halt compared to everything outside the traveler. That's Quantum Gravity, friend. :D

Ok, not mathematically trivial and relativistically invariant energy state. Reality is irreversible changes of state (quantum phase ?) combined with 2nd law of thermodynamics, that proscribes that these changes of state (a state as described by a Feynman integral ?) move to a more probable state or no change of state occurs at all. Entropy is zero or increases. Time is a measure of the rate of change of these states in a specific reference frame. Basically time should disappear in the branchial / quantum description, because if time isn't real ? Then rate of change means what ? And since space itself seems to be expanding, the quantum phase of reality must be changing continually (but that is a time reference term as well). Reality (the quantum phase of everything) increases to the more probable state or stays the same (but only stays 0 in a extremely small amount of space, the Planck unit) . Reality is constant quantum phase change outside the Planck volume, otherwise we could not perceive reality (the perception itself is only possible because of quantum phase change.) So the increase of space (volume motion ? or addition of Planck volumes ?) by creating quantum phase change produces reality. Someone else will have to do the math. But I have thought for awhile, invariant energy states, would be a key aspect of a better description. The math we have at the moment is tied to time, and it just doesn't exist. But our small brains have used time as a yardstick since we started counting days and months. It is a useful yardstick, except at the quantum scale of what is reality.

Time dilation isn't a product of computation. It can be computed, and it seems Stephen is attempting to build a theory of everything that can be readily encoded into a computer. But time dilation is a real phenomenon. It's the actual rate of time that passes for any individual object. An objects "rate of time" gives the actual age an object is in the present. All individual objects physically age at different rates. It is not merely a computation that an observer has to spend brain power on.

3:00 Even more than half a century ago, an approach to solving the problem of quantization of the theory of gravity based on the idea of Feynman integration along trajectories was considered promising. The essence of the idea is that the amplitude of the transition between the initial and final states of the metric and the material field, given on fixed hypersurfaces S(1) and S(2), is represented as the sum of all possible configurations (metrics and the material field), similar to how it is done in QM. But there are also difficulties and unresolved problems here. And this reanimation of an old idea does not take into account the nuances of GR: the energy of the particle is equal to the derivative of the action in time x(0)/c: and defined in world and proper time: E(0)=с∂S/∂x(0), E=∂S/∂t [momentum p(k)=∂S/∂x(k)]. Then E(0)=E√g(00)=const and E(0) is preserved, and E is not preserved. E=mc^2/√1-v^2/c^2, where in the static case v=dl/dt=-dl/dt√g(00).Thus, when a particle moves in a gravitational field, the energy E(0)=mc^2(√g(00)/√1-v^2/c^2 is preserved. This formula remains valid in the case of a stationary field if, when determining the velocity v, one uses the proper time measured by the clock synchronized along the trajectory of the particle.

CLOCKS HATE HIM!!!!!

There isn't any mechanism to time dilation, any more than there is a mechanism to the Uccello contraction. They are just features of the way that spacetime behaves under motion and rotations respectively.

Time is an attribute of an entity and it measures the entities rate of interaction with entities around it. So, going thru space, with little or no interaction with other entities in space, means its using less of its time; time being an attribute of the entity. If there are no entities, there's no time: time being in the universe: the universe of things/entities. But the universe, is not going anywhere .... only things in the universe go from place to place. The universe being out of time and space ..... the universe is eternal. The universe has no beginning. **And finally: there is no destroying time; it would mean destroying the universe.** And there is nothing shocking in his theory, if one bothers to think about what is time and not just the manipulation of time within equations. The trick is to ask the right question: what is time pinned to: to what does it belong: when does time come up in the scheme of things. Time only comes into play when entities act, move, or interact with other entities. **Time is part and parcel of the entity that acts.**

The math works out... Sure. This needs to be demonstrated practically for me to believe it. I think this a clock problem. I fully believe that if someone left earth going the speed of light and came back in 5 years, they would be 5 years older and so would everyone else on earth. With the clock problem however they can screw this up. Maybe play a song over and over to keep time instead of trusting a clock to judge the time traveled. I would be willing to bet they would arrive back on the final note of the 10000 run through of the song the same time the final note rings back on earth on the same 10000 pkayback.

I do however support his description of quantum mechanics in one space manifesting as gravity in ours, yet with the slight modification that both spaces are technically the same in the absolute sense, in that quantum collapse also manifests as gravity within a maximally ground-state vacuum, but that inside that singularity as distinct from maximum vacuum, its gravity is not totally overcome by the negative vacuum pressure of infinite fluctuation speeds pulling it wide, and it so can attract more of like kind within itself. But outside our singularity is both the attractive gravity (quantum vacuum collapse) that defines it, and expansive gravity (infinite quantum fluctuations at infinite speed) which overwhelms that, thus ripping it into what we (for now) see as our big bang. This can be modeled simply by showing all points in the ground-state quantum vacuum trend toward nearest neighbor & like kind.

You are implying wave theory is a string theory in 2D space. A large impulse wave begins as a trickle of itself way out in front. You are describing an exponential growth of energy at the leading edge of a wave. But what is the string median is the secret sauce.

He's a smart guy Wolfram but he keeps making "groundbreaking" claims that aren't groundbreaking.

Another good' un .👍

So time dilation is just cosmic lag?

I watched the entire three hundred seconds of which only three of those seconds made any irrefutable rational sense. 220 second mark to 221 second mark. --> Full stop. 269 second mark to the 271 second mark. --> Full stop. * * * Busts out a box crayons and thinks, I only ate twelve of these so it's still brandnew. * * * * * * Looks up at a white wall. * * * "I'm going to do big maths and figure all this out." Those three seconds are a clear display of scientific virtue. That itty bitty one percent of all that time. I like it.

Computation or energy

I'm at pains to say this, but I've watched this three times in a row - and if I didn't know and sincerely hope better, I would think that Wolfram had lost the plot - and his mind? None of this seems to make any sense at all :-(

It doesnt contradict einstein explicitly but the concept of computation sounds a bit superstitious

Time is a measurement of distance of an action. Man invented time to measure cycling circulation patterns of perpetual motion. What came first, heat or light? Heat, of course. Light is just sparks from renewable heat energy exchanging points in mass as friction as current.

Exactly, Time is only a concept, it has no physicality so it can't be 'dilated'. Clocks however are physical, and all high-end clocks are affected by the speed of EM interactions, which seem to be distorted slightly by variations in gravity.

“Stephen Wolfram: Time is not what you think it is” Many would argue the title should be; “Time is not what you think it is Stephen Wolfram.”

Mr. Wolfram may be a genius but he is past the sell by date.

I’m gonna say no

I'm sorry to say but he is wrong. Time dialation actually freezes your ability cooldowns for up to 11 seconds and slows you.

Movement does not affect time... if you think that... you have boo boo in your head instead of brains...

Love Stephen Wolfram, oy vey!

What? B space is geometrically simplectic. Like the "simplex?" That abstract tetrahedron hypercube like structure that exists in like 5 or 7 higher dimensions?😐 ..... oh shit

I don't think I'm hearing anything new. In Wolframs field of software, this might be termed refactorization.

Anyone understood anything?

Dear god some people in here are nasty. Appreciate the video. Hope you keep it up Stephan, regardless of the outcome.

Oh dear, how sad, never mind. If every particle in our universe were to disappear, there would still be mass, gravity and time. Time is the rate at which stuff 'appens, and that depends upon the density of spacetime where that event occurs. Motion does not create time dilation, relative g does. Relating time to 'information' is just particle/quantum physicists trying to stay relevant in an aspect of reality that has nothing to do with them.

you can't dilate a concept

🤯

Wolfram ripped off Tom Campbell or it's coincidence. Might be a new theory for Wolfram. The notional model that there are calculations going on "behind the scenes" of this _digital_ reality (a virtual reality) is not new.

I don't think time exists. I think time is a biological trick of evolution to make it easier to orient ourselves within life cycles from birth to death. If time existed it could not be relative to the speed at which you move, the time when it existed would have to be fixed because we all move at relatively different speeds and if time were relative, we would all be in a time discontinuity relative to each other. The one who rides in a jet plane, the one who rides in the car, the one who runs, the one who stands still, would all be in a relatively different time lag if we assume that time is relative to the speed of movement. There is no SPACE-TIME but what we call time is actually the DISTANCE from point A to point B, so TIME is equal to SPACE. TIME = SPACE.
