What does it mean for space and time to be the same thing? Not related to each other, but literally two descriptions of precisely the same entity: "spacetime"? One cannot understand existence without understanding spacetime.

Time and space are relative.
The more time I spend with my relatives the more space I need
That is so fucking brilliant!
Amazing 🙌
And vice versa
Isn't what you describe at the core of Einstein's Fear of Relatives?
Space is the ambient within where the whole universe exists. Space in and of itself can exist as being totally empty of any matter or material thing and still be as vast or perhaps infinite as the existing universe. Time however does not exist in empty space even as time does not exist in and of itself. Time is but a measure relative to the actions and interaction of all the matter in the universe.. so in a sense time is a measuring device and is unlike the reality of space.

Where he is sort of correct is around 4 minutes, in that we can only define any motion or existence of something measureable by subjective reference points. However I really don't see how that should advance a classical general relativity or "linear tidal mysterious space" over special relativity. And I don't see how the possible inherent flux of space should make a study of particle dynamics and respective force fields less important.
Because he has no idea how it all started

he ain't no more..
My favorite part is when the host says "so you are teasing apart space and time" and the guest says "yes" and the host comes back with "wow, well that's quite radical". Einstein's view, his theory, has become so well entrenched that it's now radical to think of space and time as being separate from each other. Amazing!
You are right, it is fascinating that it took less than a century. At the same time, you cant become president of the US if you dont believe humans descend from Adam and Eve!
The radicals have taken over and now empirical science is considered radical.
If time didn't change nothing could change therefore there could be no space. Without time it is impossible to perceive the existence of anything making time and space codependent.
@@MonteCarlo-rx4hu Time itself is change. How could time be dependent upon itself? It is a circular fallacy. It is like having a man lift himself up by his own bootstraps.
The one thing I would radically say is that space doesn't exist and time is not a measurement for observation... Hope Einstein would happy with my no cause & effect for things we can't see...spiritual... Hide & Seek.
I feel like I could converse with Smolin for years about the universe and we'd never have a boring second. Groundshaking perspective and insight are the one things we all can have, but only few truly pursue it.

Maybe not boring but I will get a headache trying to figure out what he is saying :-)

Lol.
If you have no idea what he is talking about then you can bet on one thing for sure...Neither does he. Why? Because truth is very easy to explain. This guy is guessing I assure you.
I have experienced that time and space are one in the same. The space I live in has taken all my time to maintain.
A while ago I was super high in the shower and realized that time is the result of everything interacting with everything. I’m glad someone else figured it out to this extent so I don’t have to dedicate my life to a PHD so that humanity has this knowledge. Based science man.
Lmao
Noice
Also, this may be the most appropriate definition of time. I. E. time=the interval between events.
Your time is dependent on your relationship with space, not your relationship with other matter. It is your interaction with space, or space’s interaction with you that dictates your clock.

When I Heard the Learn'd Astronomer
By Walt Whitman
When I heard the learn’d astronomer,
When the proofs, the figures, were ranged in columns before me,
When I was shown the charts and diagrams, to add, divide, and measure them,
When I sitting heard the astronomer where he lectured with much applause in the lecture-room,
How soon unaccountable I became tired and sick,
Till rising and gliding out I wander’d off by myself,
In the mystical moist night-air, and from time to time,
Look’d up in perfect silence at the stars.
@@jamescarew8136 to W.W.
Well done. I wish I could understand. I have 2 degrees and one of them a masters. I can accept something I don't understand.
Eg. a black hole. It is assumed it is a singularity. But perhaps it is not. Perhaps it has a surface immediately beyond the event horizon. Assumptions are made that are only theoretical and seem never to be provable.
Yes, brain hurt...I think it's about time to stop this philo-madness. It doesn't sound "profound" anymore, it nearly sounds ridiculous. Help my brain connect with my mind here: Where is all this "expanding space" expanding into? Anti-space? Conversation like this, even if they have more than 400 years of philosophy, (because let's get grounded here, it's all mental-matters, not our actual experience), it all sounds like a black hole for our common sense, interpreted as "profound deep inquiry". Do people actually get paid to sit on their couches and drool in their own thoughts. Strange occupation.
@@hittitecharioteer It is treated as a singularity because that's how it behaves. A pole in space where the supremacy of the speed of light is overcome by gravity. Physics is a lot different in its neighborhood, especially at the event horizon, beyond which not even light can escape.

No. Time is: The measurement of the change of particles in space. A particle could be defined as the smallest of all known particles up to the largest thing you could imagine.
One of your best presentations, ever. Smolin’s critical thinking, conceptual investigations, clarity of thought, and analytical honesty are head and shoulders above the majority of the characters who consider themselves as theoretical physicists.

I cannot stop thinking about time as just a sequence of different configurations of space and mass. Every new configuration has something in between it and something before it, so the order of events is clear.
No, you can't, that's how a human experiences time. You may use your imagination to try to get past the sequence but experientially you will be dealing with time in the way you describe as long as you're human. We experience it directly through the aging process. "The order of events is clear", agreed and nothing could be more obvious.
You're right it's just the logical order of causality. "Time passing" is an illusion that was created by the harnessing of our planet's rotations for tracking the day and year's passage".
@@slingshotchicken4695 He's actually right, it's your imagination that's compromised.
A very difficult subject to truly understand even when explained clearly and concisely.
He he.. it's not difficult at all. The reason why it appears confusing to most, is that the "popular science", christian fringe-mindsets and "physics philosophy" explanations have so little to do with reality and skeptical reasoning, that it can't really convince the reader or listener properly.
It "convinces" only the new age buffoons. Because they are always only looking for the least testable option.
The key points of astronomy in skeptical physics :
1 Space is the expression for the absence of something. It is where you haven't proved the occurrence of matter/energy.
2 Every locality is always in motion. There are a couple of ways you can cause change of direction or cause increased speeds ,but it is literally impossible without adding energy.
No such things as a free lunch.
3 Energy can't appear or vanish magically..
4 You can't have a cosmic beginning literally..The consequence of points 1 to 3 .
There can be a big bang. In that case it is a local event.
There is no such thing as a god or a beginning..
This is the first time I have seen Lee Smolin, but I have read several of his books, the content of which I find very refreshing. Thank you Lee for your pursuit of the trouble with physics!
Lex Fridman had a great conversation with him about a year ago on his podcast.
This is the first space I have seen him as well.
Refreshing in the sense of at least some recognition that progress in physics has stalled. Maybe recent events may spark a new revelation... ?
@@grahamswinerd idk maybe dude
@Edward Williams I assume he means that by acknowledging that physics has been running into a wall as of late, it might open the way for new ideas. I have heard an increasing amount of respected physicists questioning String Theory and the idea of a Theory of everything as being dead ends or not leading to answerable questions.
The intuition I follow is that both notions (space and time) relate to "distance" between things. Something that is farther away takes more time to reach. Something takes more time because it is farther away. Both measure how difficult it is (as in how much energy is required) to go from point A to B. It's a degree of separation.The Big Bang separated the singularity into infinity of pieces. But what does separation mean? It means adding space, or time, between the pieces. And we can observe both space and time keep going and expanding. The chain of causality they mention in the video is all these parts, energy, traveling through the spacetime.
Good
Doesn't that violate special relativity? Depending on the speed at which your traveling the amount of time you experience to travel the same distance is different right? And as you approach a large mass or travel away from it, time either slows down or speeds up. This is why our GPS satellites have to account for quantum effects.
So at a quantum level the farther you are away the more events have to occur before you arrive. Could it be that time emerges from these events? I believe Carlo Rovelli wrote about this in Quantum Gravity.
Imagine talking to this guy with a few drinks in 🤪. Much respect to him I must say and to the interviewer.

There’s a fun channel on UA-cam called something like drunk history ... the host gets the guest close to tipsy before starting the show
Oh man… I’d love to talk to him after a couple of drinks 🍻 he’s so clear and obviously intelligent, but his viewpoint and mine are exactly opposite in terms of what time is ✨🌌✨
The closest I feel I can get to understanding space time is the feeling I get when doing wheelies on my bicycle! Long live the wheelie through both space, and time!
He makes a good point, often things are considered too 'radical' when the mainstream ideas are already super radical and unproven.
Gravity is the Singularity.
Spacetime is the Singularity.
It is all tied together: wave-particle duality, the thermodynamic arrow of time, redshift, blueshift, dark energy, dark matter, and black holes, are actually all manifestations of relative infinity.
Gravity can be described as the path of matter through spacetime relative to the speed of light in relation to the Singularity (i.e. the speed of light in a vacuum. The Singularity is infinitely dense and infinitely vast, encompassing all observable spacetime and beyond). All matter in an infinite universe warps spacetime and concurrently alters the path of all other things. Since on a fundamental level all matter and energy resides within the Singularity, all matter and energy is its own cause and effect as well as the cause and effect of everything else. E=MC^2. Matter and energy can't be created or destroyed because they are fundamentally infinite. Observational physics is relative. Infinite physics is fundamental.
If you can't think on scales of infinity you will literally never understand.
An apple in your hand warps spacetime as demonstrated by Einstein, but what scientists can't seem to wrap their brain around, is that any object that warps spacetime alters the path of every other object in an infinite universe, instantly. Everything is connected.
You all want an explanation of how GR and quantum mechanics are compatible, you got it. The Singularity is the unifying factor.
Wave particle duality is a reflection of the effect of observation on the particle level. Perpetual observation of the interactions of light with our environment persistently impacts the trajectory of all particles and sets the parameters of relativistic physics.
Quantum entanglement is a reflection of the interconnected nature of reality.
The reason one particle can persistently affect another across indefinite distances, is because of the fundamental nature of gravity.
All cause exists relative to infinite effect.
All effect exists relative to infinite cause.
Observational reality is always infinitely far away from a "singular point" of infinitely high energy/information density (the relative past), and infinitely far away from a "singular point" of infinitely low energy/information density (the relative future).
This is what establishes a frame of reference for relative observation. You can never reach either "point" through the passage of time relative to observation. No matter WHAT you do, each is infinitely far away.
Light is essentially stretched from infinitely high energy to infinitely low energy. This is why light redshifts in accordance with the thermodynamic arrow of time. In other words, Dark Energy is the tension between the "point" of infinitely high energy density and the "point" of infinitely low energy density.
If you were to approach a black hole, you would never reach the event horizon from your relative perspective. The event horizon would recede into the distance relative to your position and motion through spacetime. From the perspective of an Earth observer, you would freeze at the event horizon, which is the Earth observer's relative moment in time. From your perspective, you would proceed into the relative future.
Nothing is truly improbable or probable, and every relative calculation is always infinitely inaccurate.
Every proof ever written, every word ever spoken, is infinitely inaccurate due to the relative nature of math and language as tools for conceptualization, computation, and communication of information.
We know the Universe is infinite because our language and mathematical symbols are arbitrary and relative to our experience. I can make a 2 character language such as binary code, a 37 character language, or a 998,000 character language... All the way on to infinity. This is because all language exists as a tool for describing relative infinity.
I can use our standard, base ten mathematics... Or I can create base 100 mathematics, or base trillion mathematics, using completely unique symbols that I can make up, all the way to infinity.
This is because all math exists to describe relative infinity.
The Mandatory Asymmetry Principle:
Before we get to the Mandatory Asymmetry Principle, let's start with the Infinite Precision Principle.
Both can be explained quite simply, using the basic geometric analogy of a square.
The Infinite Precision Principle dictates this: take a square. You measure it with a ruler, you get exactly one inch per side. Great.
Moving on, right?
Not so fast.
You decide to amp it up a bit and measure that square to the nearest 10,000th of an inch. You measure again, and this time you get 1.0001 inches. Your initial measurement appeared accurate, but a higher degree of precision found this to be untrue.
The Infinite Precision Principle states this: no matter how accurate you think your measurement of the dimensions of an object are, there is always infinite room to improve upon your measurement. No matter how many times or to what degree of precision you magnify your measurements, a higher degree of precision will eventually prove your initial measurement inaccurate.
The Mandatory Asymmetry Principle, when understood as it proceeds from the initially described principle, is as follows: take two sides of the square from the previous example. Let's say each side measured in initially at exactly 1 inch, then 1.0001 inches with the higher precision measurement.
You amp it up again- this time the nearest billionth of an inch.
This time, the measurements are as follows: A) 1.000100002 inches, B)1.000100003 inches.
So at a higher level of precision, you realize you never had a perfect square to begin with, at all.
The Mandatory Asymmetry Principle states this: if any given measurement of the dimensions of an object relative to observation, appears to be symmetrical, a higher degree of precision will eventually prove it is not.
Key insight: there is no such thing as a perfect square, or a perfect hexagon, a perfect pyramid or a perfect sphere.
Implications: every single object existing in our Infinite Universe is unique, and nothing can be measured perfectly in relative terms, ever, by anyone.
For every object in the universe to be unique, the universe must be infinite.
You can't measure the speed of light any more than you can measure the sides of a square. Because the only thing that is real, is infinity.
Imagine the entire observable Universe is a basket with 2 apples and 4 oranges. We live in an orange, and we can't see what lies beyond the basket.
Now, imagine the entire Universe is an infinite number of baskets, each with 2 apples and 4 oranges.
There are infinite baskets, infinite apples, and infinite oranges.
Basic logic dictates there are half as many baskets as apples, and twice as many oranges as apples.
The basket is like our observational bubble. Every phenomenon we observe happens inside the basket. The ratio of apples to oranges is like our physics. We can define the physics within our basket in relative terms and convince ourselves the description is accurate.
Or, we can define the physics of the infinite Universe in terms of the frequency of apples and oranges relative to infinity.
That's my take on it all!
I have literally been called delusional and an arrogant narcissist just for putting this idea out there, to your point. I think it makes perfect sense.
@@ericfarina9609 very good!
@@PedroFinGuitar I hope it makes some sense. I know I am not an expert. But I believe the Mandatory Asymmetry Principle is logically unassailable and that the implications are extraordinary. Language and math as tools for conceptualization, communication, and computation always leave infinite room for improvement no matter how you construct them.
As language and math are the conceptual tools on which physics is based, the implications extend directly to our understanding of physics.
A true understanding of the Singularity unites Quantum Mechanics and General Relativity with ease.

Time DILATION ultimately proves that electromagnetism/ENERGY IS GRAVITY, as C4 is a POINT that is ELECTROMAGNETIC/GRAVITATIONAL (ON BALANCE) as SPACE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY.

Too bad
Try thinking about time as a measurement of things that have a physical presence and affect other things.
Events always include (almost by definition) movement, the movement, from one place to another of something tangible, such as matter or radiation.
Time measures the changing movement of objects but has no power, energy, or effect on anything.
An accurate analogy is Temperature, which doesn't make a thing hotter or colder, it only measures one particular state of an object. Time is no more a "thing in itself" than is length. Both are measurements. If nothing moved there would be no time.
Yes actually you are correct. As a child I looked at a clock and wondered if I could stop time, or by concentrating on the second hand, slow it down. Obviously one cannot, becauuse it is the movement of the hand from one point to another that we take to represent time. That is how space and time are related. But to go further, don’’t think in terms of material things - ultimately there are only patterns of energy. The clock is a mechanical pattern, the solar system is a gravitational pattern, and so on. Ultimately all “material” objects are just patterns of energy (as far as physicists can determine at this “time”). Then Smollin’s point of view makes sense, that causality is just patterns of energy interacting. Whether one billiard ball striking another, or running into a friend and talking about the football game - in which case the patterns are the stored memories in your brain interacting.
Not a measurement as it will change depending on the effects of entropy on different types of mass. Its just the process of mass moving toward entropy.
If nothing moved, there would be still time, place a clock in vacuum, time still ticks
@@ivanmenezes640 but if nothing moves,then clock also doesnt move and doesnt show passage of time... So,if nothing moves (including clock) how would you know the passing of time? Thats the question
Wrong while it's not possible for all things to stop moving.
When I was five years old, I looked up at the sky and wondered, how can it go on and on forever and ever? My next thought was: But how could it stop? 70 years later, I still haven't figured this out. Has anyone?
Space is infinitely large, you could keep going in one direction forever. But is space also infinitely small?
I had the same experience at 5 years old, just as you say: looking out my bedroom window at the stars. Maybe this is more common than I thought. For me the idea of infinity and my inability to grasp it created sort of an existential crisis.
Me too now that I think about it space is infinity big but then is it small
The thought of being outside or beyond the edge of the Universe is preposterous. To even question it IMO is lunacy. Nothing can not exist. Nothing is still something if you have the idea of it. The Universe is literally everything that can exist.
It could be limited, but also "go on forever," if it looped around on itself. However, by best measurements today, we cannot tell if it will loop around on itself, or if it just goes on forever. It's definitely much, much larger than the furthest out that we can look -- scientists have figured out that much.
Not infinitely small. The lower limit is the Plank Length, but don't ask me why.

@@b.g.5869 This is not a 20 year old interview, it's from 2013/2014. Anyway, our understanding of Space and Time has not been changed in the last 20 years.
This is so fascinating to me, but I wonder how to really understand it.
One way is mathematically via the models of quantum mechanics (complex vector spaces) and general relativity (differential geometry).
An intuitive approach would be to think about walking. I walk from my bed to the door. These are two distinct points in space and time, i.e. where I am is a distance away from where I'll be, and when I am is a distance away from when I'll be. Now add in a magical observer a light year away, who watches me walk to the door by analyzing the light that bounced off me. It takes a year for the light to get to the observer, adding another distance in both space and time. Relative to the observer, that event (which caused the information on the light that informed the observer to exist) is happening right now (since they are seeing it right now). Relative to me, it happened a year ago, likely in a very different place from where I am then. What relativity says is that both people (or frames of reference) are correct; time and space are relative to the observer. Now what can we say about the relations of these two people? If I wanted to tell the observer something, causing a thought process in them, light would have to travel to them. The relative amount of time it would take IS the amount of space between us, and so the two are isomorphic (can be mapped onto one another 1 to 1).
This is how space and time are combined into spacetime, and their relation is entirely constituted by causality, specifically its sequencing (how long it takes for information to travel). Hope that helps a little.
space and time are simply dimensions. If you want to meet me at a place (space) you need to know the time, conversely if I say meet at 12 noon, you say where (which location or space). one cannot exist without the other, hence the definition space-time.
If the sun were to suddenly be switched off or cease to exist, it would take 8 minutes until we realise it. at which point it is too late. 8 minutes of unaware bliss... cause and effect, with space-time.
@Gourav Gupta In order for information to inform, it needs a time and place to inform. If this were not so, who is going to receive the information? Eliminate space first, and just propagate information through time. Is the entire universe now aware of this information for the rest of time? Where did it come from? Where does it apply? You dont get a lot of info without the spatial coordinate. Now eliminate time. Does my entire timeline now have the information? If that's so, could I use that info to change my future, creating paradoxes? When is this info applicable? Without the time coordinate, information will either be paradoxical or unusable.
I could be wrong, but I think he’s just simply saying that time preceded the Big Bang. Where as space did not. Extrapolating; could really lead towards other dimensions / Universes.
Some good animation illustrating these ideas would be very helpful here.

Unifying space and time at the quantum level invites us to explore the very fabric of reality itself. In the quantum realm, space and time are no longer fixed and separate entities, but interconnected and dynamic, fluctuating in ways that defy classical understanding. Quantum mechanics and the theory of relativity have shown us glimpses of this, suggesting that spacetime can warp, stretch, and bend, influencing the behavior of particles and energy. If we could fully unify space and time, we might unlock the deepest mysteries of the universe, revealing how the cosmos truly operates at its most fundamental level.
Smolin rocks!

Yes, but when Robert asked (who by the way is really getting better and better at asking the right follow-up questions) about the difference between the block universe and his( Lee's) concept I felt him getting a little uncomfortable when he had to admit he had to rip apart spacetime.
@@emmanuelpil His feelings about the facts do not diminish and are not the actual facts, and he admits those fact.
@@ZeroOskul Yes but the quantum theory of space-time in loop quantum gravity is really just a quantum theory of space. The spin network described by the theory cannot yet incorporate time. That's where the discomfort comes from.
If Sci-woo and waffle is your thing... How has he advanced engineering, I ask, as an engineer? More of a mathematical philosopher.. If anything, this type of mindset is the main cause of the fundamental physics rut... Too wishy-washy and abstract, not concrete enough... Here's the opposite approach from a good engineering standpoint, premised on do more with less.. Nature is conservative. The main conjecture is that either almost all or at least 50% of Positrons do not annihilate, but instead explain and simplify the Standard Model.. No way nature would waste the positron in my book... It's a self balancing system and the continuous attempt to re-balance permanent imbalances emerges the material universe we measure.

Matter-Energy: Matter is focused energy.. Energy is mobile matter.. Momentum conserves velocity.. Force changes velocity and/or direction

Positron/Up Quark/Graviton (p+): Free, mobile out of place cell warps the field, radiating AC field cell vibration 'blip' spheres at C + 6 DC spin loops

Electron/Down Quark (e-): Hole left behind warps the field, radiating AC field cell vibration 'blip' spheres of opposite phase at C + 6 DC spin loops

Noton/Dark Matter (n+-): Exactly opposite phase close p+ and e- annihilate (ie. entangled pair created together (e_p) ), else a noton forms

Nucleons: Proton: P=pep.. Neutron: N=P_e=pep_e.. Beta-: N-e>>P+e.. Beta+: P+e_p>>N+p.. Alpha: A=PNPN=PeP_PeP=(pep_e_pep)_(pep_e_pep)

Heavier Fermions: Larger holes and chunks of subspace field rapidly disintegrate to p+s, e-s, n+-s and/or annihilate to regular = empty field
--
Electrostatic Force: Recoiling blip spheres propagate. Opposite direction + and - blips form a vibrating AC bond, same sign = phase repel
--
Instant-Off Long Force: AC (longitudinally blipping) subspace 'flux tube' as thin as 1 cell wide. Each cell and its -ve gas move in contrary motion
--
Spin: e-s and p+s pull in the 12 surrounding cells, or -ve gas that pulls cells, that then bounce out, stabilising as a torus of 6 in/out (N/S) DC loops
--
Strong Force: Spin loops merge and form flowing DC circuits between e-s and p+s
--
Mass: Sum of the lengths of all strong force bonds + near electric field. Notons have compact strong force bonds, Protons' are long as 2 p+s repel
--
Magnetism: Some spin-aligned atoms' p+s and e-s' strong bonds join in a shorter straight path. Energy conservation results in external force circuits
--
Left Hand Rule: Magnetic circuit cells squeeze between field cells causing short range, lateral, perpendicular electrostatic blips

Weak Force: Geometric structural charge balance instability. Possibly noton hits statistically tipping the balance

Photon: Charged particles moving up and down (transmitter, atomic electron) form a radiating transverse wave blip pattern
--
Double Slit: Laser light / particle centre's preceding, extended subspace distortion diffracts, interferes, forming wave guides observation destroys
--
Dark Gravity: p+ traps 1 quantum of -ve gas so void cell size/gap grows (and matter's shrinks?) forming a macro -ve gas density gradient
--
Bang Expansion: Loss of -ve gas to the multiverse?.. Bang ejector velocity petered out, magnified in time by outward momentum conservation
--
Gravity Wave: Longitudinal wave where the entire field in a large region is effected in unison for a duration
--
Big Ping: A dark crystal universe collisions' intense gravity wave forms e- & p+ pairs inwardly at C that annihilate or form notons, Protons, Neutrons
--
Big Bang: Ping wave collides centrally? Field blast forms matter + a large hole (then Big/Dark Refill)? Fast -ve gas loss? Noton crystal exploded?
--
Black Hole: Absorbs matter and energy. Noton crystal (with a core returning to empty field)? Large hole in the field traps anything entering?
--
Frame Dragging: Entire sphere of subspace cells rotating around a point in unison
--
Time: Cell to cell blips take a constant time. Gravity shrinks cells so light slows but locally measures C as circuits lengthen in space & time, adding mass

This is not an aether theory, it's a matter-energy field, a quantised, relativisitic subspace medium. Forces and matter emerge from and are part of the field

@@PrivateSi I don't think he's an engineer... but he HAS done at least one thing:
Critical editing was invented around 400BC at the Great Library at Alexandria.
This was around the time of Socrates and the invention of Socratic Argumentation.
Critical editing lies in looking at a work and rewording it to make it better express the meaning it is intended to deliver.
I reviewed, edited and revised this before posting.
Critical editing can replace whole paragraphs of vagary with one sentence of solid description or remove a nonsense sentence and replace it with an informative paragraph... it can even omit whole chapters.
Socratic Argumentation involves honest evaluation of one's own argument and a willingness to compare it to their opponent's argument and to be willing to accept parts of the opponent's argument and to reject parts of one's own if those parts show to better or worse describe the idea being argued over.
In a normal argument, one generally makes a bold statement and defends it to the end even if it is shown to be inherently false.
Two hundred years later, also at Alexandria, the scientific method was invented and this was done using the same essential rules of Critical Editing and Socratic Argumentation but based on claims about facts, and so leading to the invention of expermentation.
2,222 years later, give-or-take a week or a decade, Lee Smolin said:
"What is good for scientists to do?
"We have to be honest, we have to argue in good faith, we have to work from shared public evidence.
"Because it is so easy to fool ourselves, we develop crafts.
"Crafts of experiment, checking our experiments, checking our calculations over and over again to detect error.
"And, indeed, the training of a scientist is primarily a training in the detection and elimination of errors.
"It's not about ideas--lots of people have ideas and every once in a while there's a good idea--it's about showing that your ideas and other people's ideas are BAD ideas by finding errors.
"And a scientist is somebody who has a degree that basically consists in demonstrating that they have control over... mastery over a craft for detecting errors."~LS

Last night I looked up at 8:07 and watched the space station pass overhead. I thought about the humans working, sleeping, living in that small ship with ultra thin walls separating them from the cold vacuum of space. I thought about how I can see their temporary home and that they are actually aging slightly slower than me. That is all.
Wow. I looked up just a little bit ago and saw it at 8:26 and thought to myself, “boy, I sure am stupid for writing this and going to that website to make sure I write down the actual time I’d see it.”
Time dilation is a myth based on assumptions made while viewing some rather sophisticated yet flawed math. No experiment has shown that time passes more slowly while traveling faster or further away from a large source of gravity. All we have as a proof of time dilation is the the atomic clock. While the time difference that occurs in earth based clocks vs space station clocks appear to prove time dilation, that is a mistake. It could be a property of the cecium atom. It could be some other phenomenon yet to be explained. It is circular reasoning to use the math, thought experiments based on the math, and a single observable fact to confirm that which is known to be in error. Yes, Albert was brilliant, but his relativity theories are flawed. Like Newton before him, his theories are good enough for our purposes, but not totally accurate.

Think of space/time as a frame rate.
Like when you look at old celluloid movie reels. Where there is one frame then another and when you experience them in sequence it brings them to life and you experience an animated image and TIME. Just like how they make cartoons frame by frame by frame.
The frame rate of the universe is a staggering 12 sextillion times per second and that is a real number. A 12 with 21 zeros behind it. This also happens to be the speed of light and maybe contemplating the speed of light will help you comprehend this deeper as well.
LIGHT does not move. It bumps into its adjacent space 1/17,0000th of an inch of ether causing it to move and send waves. If you have ever watched a huge long freight train start or stop you hear on car bang as it grabs the one next to it and then the one after that bangs and on down the line like dragging a stick across a chain link fence or putting playing cards in the spokes of your bike with a clothes pin.
Time and space are one because it is really our consciousness that is moving from one frame of space to another at a determined frame rate. Everything is consciousness. Matter is just a shadow of all else that makes its perceived existence possible.
I have to read it a few more times, but your explanation sounds brilliant to me!
1 You haven't at all understood The photoelectric effect. Which is not a hypothesis, but a verified science experiment.
Which debunks your claim in the start about light.

Something that annoys and worries scientists and skeptics more and more every month.
2a: Space is the definition of the LACK of matter present. In other words, something completely non-motional.
2b: All matter is ALWAYS in motion. Continuously. Non-synchronously. (A k a non-uniform, or if you like, "relativity").
Now it should be obvious to you that there are no "frames" in nature. Optical systems create frames because they can't suck in infinite data... :)

But, assuming physical causal closure and consistency *what* is our perception *of*, if not *that* of what-happens/events in spacetime?
i tend to think its alittle of both, things may only move because of a medium that lets it move.
@@patrickwithee7625 That's why you don't assume physical causal closure. We're given metaphysical closure by principle. Anything causally operative can only be described, interpreted, measured, experienced within reality itself. That's the starting point. Physical causal closure is D.O.A. hence, quantum uncertainty.

joseph Freetimer look deeper my friend….free inquiry has brought about all your/our conveniences…
@@johngrono what do you mean by this?
@@josephfreetimer1736 it’s not the most straightforward concept to explain, but I’ll do my best:
Imagine a graph, or perhaps better, a map, drawn on a grid fixed so that every location (point on the graph) has a location defined in reference to coordinates on that grid. Now, imagine lengthening all the edges of the grid’s squares, so that the graph/map/whatever you’re imagining drawn on it stretches along every axis. That’s what expansion of space in the universe is like, except that the matter within the space (everything physical) is ‘confined’ by the attractive forces (electromagnetic, gravitational, strong, weak) it feels and imposes on all the rest of the matter local to it - such as, for example, the attractive force the sun and the earth have on each other as they orbit - keeps the material within the universe “locked” into relative positions with respect to other matter, so that although the fabric of space within which it is contextualised expands, the matter experiences only the slightest of affects, which are dwarfed by the much stronger affects of the forces, due to fields such as the gravitational field which drives change in their relative positions.
This is general. Actually you are (at all times) being pulled outwards in all directions simultaneously by the expansion of space, however the attractive forces (predominantly electromagnetic and strong) between your constituent atoms, and the subatomic particles within them keeps you whole. Without these, you would spread out into a diffuse cloud (albeit imperceptibly slowly) as the universe you are imbedded within gradually expands. Note that this gradual expansion is radically slower and less impactful than the rapid expansion the universe likely underwent in its inflationary phase (according to our most likely theories).

I've wondered if quantum entanglement itself describes time as being a flat object or characteristic of reality, rather than our perceived river of cause and effect. This stuff is so good. Although rather abstract, these notions give more of a feeling of deep wonder toward creation than any books or stories ever did.
Diogenes had it right from the start.
"All things that come into being are a conflict of opposites, the sum of those opposites, flow like a river"
I view it as the flipside of statistical nature of QM. Entanglement keeps particles in check across the universe.
I'm in no way a physicist or even close, but it always seemed to me intuitive that time doesn't exist, only change. The faster you move the slower things change. So it seems odd to me that everyone keeps referring to time as if it's a thing.
It would make more sense to me that things are based on causality as was said in the video.
But what do I know?
That's what I've been thinking and debating for a few years now:) Time doesn't exist. There is only space. Since the beginning of the universe till now there is a constant movement. To measure the gaps between for example some past and present events people invented a descriptor "time", but it has no value itself, it's just a measurement. There is no time per se, there is only space and change.

Great idea! We could bottle the time particles and save it for those busy days!
If time is the expansion rate of space and if gravity slows the expansion then you can easily understand why time is relative and how it is related to space. Time isn't a dimension it's the expansion of the 3 space dimensions. Because space is expanding but not contracting we have the arrow of time.
Yes, I think of a simplified universe with zero motion then within the universe there would be no time. Within that universe how could you determine any time. You need rates of change of distance between three points or objects to have time (two won't work).
Apparently the more profound you are, the more you tilt your head until it's almost sideways.

It depends on which side of your head you are using at the time
Because to go from any point A to any point B, you need both Space and Time. Like electricity and magnetism, both Space and Time are inextricably and eternally bound together. 😊

Dear Dr. Kuhn. Thank you for such a great contribution. Dr. Smolin clearly explained theoretically the causal link between space and time in close relation to events in space and time, because time is not an illusion, particularly when it is applied the Physics, Chemistry, etc in scale. The science in scale together with the utilization of cosmological laws, it explains the differentiation of organizing systems in a certain space and a certain time in the causal link space-time. Doctor Smolin only is using as well known in the scientific circles an effort for experimental agreement of "one single worldedness", to pacify the scientists arguing for the one universe, and those scientists arguing for the multiverse. But "one single worldedness", Dr. Smolin knows as well it is the same attempt that Newton or Leibniz tried at their time in order for their scientific theory to win. Dr. Smolin has done a great job, but he should continue it further in theory with the help of practical experiments of different scales.

So, about you accusing another fellow human about pretension of being intelligent and knowledgeable, and even you issue the threat with sweetness to stop self-embarrassment of discussing scientifically about scientific problems with scientific arguments, which you do not understand. So, I cannot accuse you for "lol" ignorance, because ignorance is not a fault, but it is simple that if I do not know something, others can know it better. So, in your case if you do not know something you have the right to express your opinion, which is not scientific. You do not know that the great Newton, meanwhile became famous for his laws of motion in his main work, "Philosophiae Naturalis Principia Mathematica", it is not publicized or it is spoken very little, that Newton was conducting experiments and he was a proponent of Alchemy, which was based on utopic delusions of discovering the Philosopher's Stone. In that context, the scientific contribution of Newton is well accepted in our planet Earth, but also it is understood the restrictions of his scientific steps in his thinking that our planet Earth is the "lucky one", as Leibniz was stating in his "Philosophical Essays", that God created our planet Earth as the best world. So, my arguments in scientific view of such restrictions in scientific knowledge of Newton and Leibniz, were in the European religions endorsed, stating that "we are the center of the Universe". The idea that we are the center of the Universe is not true, and it is proved by the existence of other extraterrestrial civilizations, which for I do not need to go in further discussions.

It sounds like he's explaining time as a movie with an infinitely fast frame rate, each frame being a 'moment' in time.
Well..kind of…but not infinitely fast. Time has a minimum interval. Plank time. This is the time it takes for light to cross the plank length…Which in practice means the minimum wavelength of a photon that can exist. It is incredibly short…billions of times more brief than our best clocks can register. Something like 10e-48 seconds.

Time is a measurement of movement across a given distance. It is a measurement, not something that can be measured.
Space is an area, not a thing. There can be things within an area but space is different from those things.
We try to claim that space-time is a thing yet we can’t even claim that space nor time is a thing. 🤷🏻♂️
Hey! Movement across distance is more velocity and speed. Time is causality and entropy. These two only move in one direction: Cause to effect and unbalanced energy to balanced - more or else. One thing they discuss here is whether spacetime is just an emergent property of particles and events and thus not a "thing" in the same way particles are a "thing". So yeah... spacetime might just be a concept of understanding and not a "thing".
@@emersonkyle6039 - When I say time is a measurement of movement I mean that a clock measures an incremental number of movements (mechanically, atomically) or prior to that it was the movement of the sun with respect to the earth. It’s a measurement of something from point A to point B not a measurement of time itself.
The same goes for space. Space is not a thing, it’s the absence of a thing unless you put something in it (space).
I get what you’re saying and like you suggest, it might be conceptual. I just don’t subscribe to scientific conceptual understanding without proof.
It’s like the value zero. Zero has no value and is literally nothing. Conceptually we can make a temperature zero but that’s only because we create a baseline and then create negative numbers. The convention of zero and negative numbers have value to us but that doesn’t make them any more real.

Space and time are words in human language. They are interconnected by the active human consciousness. There are many definitions and uses of these words. Lee made a great point about counting. We create the concepts, a step beyond the words, by counting systems based on measurements of space and time. What is space and time? They are what you number and count.
The deeper these conversations get, the more it sounds like we are discovering how the simulation we are in is produced. That casuality creates what we call space, certainly.
It fills me with awe. My son programmers computer simulations and the fractal of this, at least to me, is that there is a designer behind this phenomenal complex simulation. For others I realise it doesn’t point to that. But I sure hope they are wrong as I want to ask so many questions. Only time will tell.
You would be wise to deal with what you are calling a "simulation" as reality. If I viewed life on planet Earth as merely a simulation I would definitely be requesting tech support for some major adjustments. Maybe you aren't in a simulation at all, maybe you are "in" what is real and you are the simulation. That is just as viable for me in your case, just some simulation for me to deal with as I please. When you shed the layers maybe you are really just a simulation of a simulation of a guy who doesn't want to admit the table is real until someone smashes your head into the table. You are merely the speculation of a simulation, like a photo of a fake Gucci bag. The real Gucci bag is beyond your grasp, and the real Universe is actually the real Gucci bag in Caitlyn Jenners closet as she/he is is just a simulation of a man/woman. Even your thoughts are a simulation. I think you get the idea of what I think about you calling reality a simulation, it's like believing the election was rigged. This is as real as it gets, if you want to pretend life is a computer game I think the pain and suffering may teach you ohterwise.
@@slingshotchicken4695, or, the reality of the situation could be that, while our experiences in this reality are real, we are all pilgrims in this place. This is not our end destination, but is a place for us to check into, learn from, and then check out of. Once on the other side of the pilgrimage, we, as changed individuals, get to look back at our life in the simulation and determine how well we did with what we were given. We move from an existence in eternity, to an existence in time, back to an existence in eternity so that we can experience the change that we can only receive when we exist in time. Without time, there would be no way for us to measure our change, so the time element of the simulation allows us to see where we've been and take stock of our progress.
Who is simulating the simulators then?
FWIW, the actual "simulation argument" that infused this into popular culture starting 20-some odd years ago isn't arguing that we are living in a simulation. Nick Bostrom's paper was about what we CAN know about something that seems like we couldn't possibly ever know anything about for sure. The gist of it is that either we will never run (because we can't or choose not to or go extinct or whatever) "ancestor simulations", or that we are almost certainly living in such an ancestor simulation. It doesn't sound very impressive at first, but if you read the paper, it really is brilliant. Yeah, that is not a firm answer about anything, but being able to say anything at all with any degree of certainty (even if the certainty is just about the odds) about that is pretty amazing. And yes he does deal with simulations in simulations in simulations ... He personally does NOT believe we are living in a simulation (well, that we probably aren't). He even shows how you can have a rough idea of the probabilities of different scenarios. To me, this is way more interesting than just speculation.
I would see it as the same thing as saying you live an hour away from somewhere in place of the distance. It takes time to cover distance so the two must be linked.
And mass (gravity) bends space time, this has been observed as time slowing. We can tell by measuring the speed of light being affected when measuring start light at solar eclipses. So for what he’s saying to be true, you’d have to assume speed of light isn’t constant and limit in universe as well. Or this is about as deep as my head can wrap around this listening with a beer in my hand. Interesting idea. Whoops didn’t mean to reply was just trynna post 🤭🤷♂️🤦
@@32kirby32 Speed of light is not constant everywhere in universe, it is affected by the environment that light pass through.
It cannot go faster than is limit in the void, but it can go slower... :)
(No beer in my hands, but my knowing of things is pretty much yours... if not lower) :P
You live an hour away as the crow fly’s, at what speed? There is no circumstance where you live X amount of time from location Y. It’s not possible.

Description in Simple terms😂
Really interesting down to earth person that I could listen to all day. I've been thinking the same thing but I definitely lean towards time being an emergent property of more fundamental things interacting, such that it does not exist. The same thing goes for space. Space is "is" that thing interacting i.e. space is just energy fields and configurations providing certain interactions and dynamics. This is of course very complicated as energy exists in many different ways: fundamental forces, solid masses, vacuum with particles blinking in and out of existence and certain quantum environments (think about cmb, dark matter, vacum decay etc). From that perspective I'd like to visualize it such that space, or energy, flows through objects. In certain cases it's very obvious, like with the fundamental forces. In other cases it's only noticeable when you travel at large speeds or hang out with massive objects. This flow slows internal speed, but not external speed. Which then is a way to view time dilation. Of course, these are all very complicated relationships (hyperbolic for instance) but at its core, at the end of the day, it's "just" a swim through a surprisingly complex but structured soup.
Superb!! Really want to rewind and ask for clarification on a couple of points (as a drop-out Astrophysicist)... but still, superbly done! Thank you.

The connection of moments is an illusion created by our own entropy.
Ok, But then why Can we mathematically predict certain event, why Can we make such precise forecasts?

Exactly!!! So just what did you learn???
Terrific interview. Thank you.
I am not in any way qualified to draw conclusions on the subject matter, but my gut screams that time is in fact emergent. I understand that lack of technical progress with a theory necessarily colors our judgement of it, but we should step back and consider the quality of this particular juncture. Perhaps more than any other obstacle we've faced, understanding this aspect of reality may be the most challenging. In this type of situation, it seems to me that partial progress with easier postulates should be suspected to be caused only by the relative ease of the postulates, and not them being rooted deeper in truth. It is inherently easier to consider that something (ANYTHING) is primary, while all else is emergent. The frame of reference that provides is inherently psychologically reassuring, as well as mathematically grounding. And time is of course the most likely candidate for us to WANT it to be primary and non-emergent. It seems to rule our lives so completely: to be a phenomenon we cannot harness or manipulate (yet) the way science has habituated us to expecting it will allow for us to do. But that does not make it fundamentally or universally true that time is primary, anymore than Newtonian physics was fundamentally and universally true. Newtonian physics just worked really well for us until we discovered areas of reality in which it didn't. From my limited perspective, this is what comes to mind when I hear the bias against time being emergent.
As always, I enjoy listening to Lee Smolin.
Space and time are not the same, but they are connected. Nothing can occupy the same Space at the same time as something else. As you move through Space, you inevitably move through time. As time is always passing.
Fascinating concept indeed.
1-2:00m He's nailed it in a common language explanation of Time and Space being in the nature of relationships between elements of the Universe. Exactly! Now take it to the next level with a discussion of Quantum Dimensionality.
I have a UA-cam playlist called "Food for Thought", and this has been added.
This is up there with "Why is there something when there could be nothing?"
There can't be nothing. Nothing, by definition, doesn't exist. To exist one must possess attributes. To have attributes one needs identity. The Pauli exclusion principle is the physical manifestation of the concept of self identity. No two members of a group can possess all the same qualities as another member without actually BEING that other member.
If A-B=zero then A=B.
How do you know there could be nothing? Only meaningful questions have answers. How do you know it's a meaningful question?
There have been multiple addressals to your question and many other fundamental concerns about existence in this channel itself. So many great physicists, mathematicians, philosophers worth listening to
@@KaliFissure That’s just semantics. Rephrase the question as “Why is there something, rather than the alternative?”

Sir. There wouldnt be much of a "pandemic" without the internet..

@@spactick u sir, have bought the narrative they sold you. The paradigm we are looking at the same facts through is so different, there is no way for u to see my point. Although I do see yours.

It seems like there are so many varients now and to come that no immunization could possibly be effective especially if rushed like they all have been.

@@adamcombs2739 i totally agree with you, the Biden administration (democrats) have used this pandemic to both
forward financing and push thru congress programs that they otherwise couldn't get thru in normal times. But!
in the 1918 Spanish Flu epidemic 50 million people died, and in this pandemic were presently at 3 million with a
far larger world population. I believe because of the advances in communicative technology. If not for global media (telecommunication) the death toll would have been 300 million, easily
Time is the effect or result of the expansion of space. The faster you move through space the less effect you receive and conversely if you could slow your motion through space time would move faster as the effect would increase. If you could move at the speed of light time for you would nearly stop. This is how time and space are related as one cannot exist without the other.
So, if we existed in a different galaxy spinning at a different rate, travelling at a different speed, rotating on our planet at a different rate,
Would the universe be younger or older? In relation to us now?
@@evanvaneck2771 different. The universe is 13.8 billion years old relative to us.
If we think of it all as a blank field or a movie screen where actual multidimensional objects appear and go out of existence, the screen itself is having the time or experiencing the show of reality. We are all just objects and players sharing in the reality from our own perspectives.
Yeah

@@williamesselman3102 If it's true that we are, everyone. But is it true?
No. We are more than material objects.
Actually I am proud of myself I think I understood the part about separating time and space because they can't make the physics work so he is trying a different approach which is to separate time and space.
It's interesting to note how our level of consciousness is seldom equated into these observations....that time could be a result of our limited consciousness. The brain's evolution may require sequences of events (causality) to create reality rather than being able to perceive our universe as a unified whole. It seems that consciousness as the observer must be factored in. Thanks to Lee and Closer To Truth.
Space and time are not the same thing...space can exist without time...time cannot exist without consciousness...Consciousness and time are the same thing and we see it in the form of light...Light contains both time and consciousness.
psychobable. take it elsewhere or get sober
@@matttirado7661 Are you just making this up?
The PASSAGE of time is an apparent effect that our consciousness seems to generate - it's how we see things. But that does not mean TIME is created by our consciousness. Otherwise you'll have a hard time explaining how a billion years of time could pass before the first "conscious" animals evolved.
@@DavidByrden1 what part of the truth do you not like?...try and wrap your head around the fact that everything you see and touch is conscious...anything that can carry information is conscious...the big bang was conscious and Consciousness is eternal. ...Without it's math you will never be able to comprehend your world. Time is a different form of consciousness that can exist in a vacuum but will break down under the extreme pressure of infinitesimal gravity
Amazed at how far humans have come seeking a 'truth' which may not exist after all. I do enjoy listening to all those 'possibilities'. Understanding how our universe "and beyond" works, has been elusive. Maybe we do lack some pieces of the puzzle, assuming there is a puzzle in the first place.
"Truth" does exist and it's definite. You simply can't have anything causal without it.
Some pieces? Lol we lack almost everything.
Truth exists, “thruth,” on the other hand, doesn't. 😬😆
@@st3althyone I've fixed the typo, thanks.
I think we delude ourselves if we think we can achieve getting closer to "truth" (a human concept) by using the same brains that invented that concept.
We are just hairless apes that can think and imagine abstract bullshit with unknown and known millions of preconceptions, cognitive biases and other nature baggage byproduct of evolution and the survival warfare, all the past the began in this planet 4.5 billion years ago when the first proto life form emerged.
Then as much as brilliant minds exists to imagine and invent new ways of thinking and models of reality, the harsh truth is that our brains is our hard-ceiling. The more we approach the fundamental stuff the more it eludes us because of our ego centric way of thinking. Scientific progress about our fundamental reality has been hindered by linguistic traps that the human brain puts there without us realizing.
Try to imagine a universe were we humans or any lifeform did never existed to begin with. Therefore no conscious minds to perceive it, experience and try to discern it. What happens then?
This mind excercise should be practiced more because too many scientist fall into this antrophocentric principle trap without even realizing and this contaminates everything, even math and pure logic. Because we cannot avoid ourselves.
It's interesting that he mentioned a universe that was positioned 10 meters to the left because there was a Futurama episode in which the main character Philip J. Fry ended up traveling through time (don't ask me how, this doesn't make much sense to me either) to a universe identical to his original universe but different only in that it was positioned about 4 feet or so to the right from the original universe, in a time-travel episode, using Professor Farnsworth's time machine which only travels to the future (to prevent time travel paradoxes, according to Farnsworth). ✨
Futurama creator also made Simpsons and all sorts of weird truths were revealed in those episodes.

My physics professor used to tell us : You can count on your fingers the number of physicists in the world who really understand GR and Spacetime. She would always end her semester by saying: I hope I have confused you enough! 😮.
Lee's 'Life of Cosmos" taught me to take the whole universe into complete understanding (Einstein's COMPREHENSION). If we think local, time will have a beginning, apse give a singularity, infinite, none of these make sense as because infinite space and time are indispensable.

Assuming we can see how dreams come to manifestations perhaps we can pray out of time from our own space...we are simply trying to understand what we didn't create. Why should measure space if it were just a single mass in which we live in physically & spiritually... #TimeIsEverything
Sorry, compliments due for reading Lee's work, yet Your manner of presenting in this chat post is poorly expressed.
@@olarenwajufalusi4979 also poorly expressed...
I loved the simplicity of viewing physics as an infinite set of causalities. It seems to me that both space and time are emergent from that view. I was confused by how he contradicted himself in the end by separating time when it is perhaps even more derivative from causality analysis than space.
One must be good at that theory thing. And focusing too.
Most of our confusion is self-generated, and produced by a disconnection from the general theory of Common Sense, which doesn't need an expert to create in their free time.
I think it's about time to stop this philo-madness. It doesn't sound "profound" anymore, it nearly sounds ridiculous. Help my brain connect with my mind here: Where is all this "expanding space" expanding into? Anti-space? Conversation like this, even if they have more than 400 years of philosophy, (because let's get grounded here, it's all mental-matters, not our actual experience), it all sounds like a black hole for our common sense, interpreted as "profound deep inquiry". Do people actually get paid to sit on their couches and drool in their own thoughts. Strange occupation.
@@josephfreetimer1736 Great comment... and another thing I note too is this effort at attempting to have a unified field theory or what they've called "The Theory of Everything". It just appears the acedemics are trying to describe reality in mathematics and if it gives the expected results then given time passing, it must be true because the maths doesn't lie. (Does Dark Matter ring a bell here?) Yes, I know about Newtonian mechanics were superceeded by Einstein's Special and General theories we have today but this was all capable of being proven by scientific experiment. The leading candidate for the TToE is so-called 'String Theory' which is impossible to prove now and in the future.
I'll just return to my couch and sip on some tea and contemplate the expansion of the Universe, and get paid for doing so from the public purse.

I’ve always “felt” that the two where distinctive of the other. Space to me is distance between point A & B. Time is, what it takes you to get from A to B. Speed of light is not faster than the speed of space.
It doesn't matter. You are talking about mutually exclusive ideas. Causality is what defines spacetime.

If meditation reveals, then (General(s)...heed) time is a potential (i.e. amplitude) not a cause. These people, figures, that we know of from many years from their time have amplitude.

I think time is an invention to describe the movement of matter over distance. If you stop every particle from moving, you’ve stopped time. If you move every particle back to where it was at any previous point, you’ve gone back in time
That would be ignoring bell’s inequality where a particle wave has many movements spontaneously determined outside of measurement and time. If you move a particle from point A to point B, we could observe the time it takes to travel that distance but we cannot observe the superposition of other paths it has taken.
Everythin stopping is the present (now).
