Our perception of time often relates to changes in our surroundings or within ourselves. The concept of time is intertwined with changes in states, events, or motions of objects. When there's no change or movement, time can seem less apparent or perceivable. Time often becomes noticeable due to the transformations or alterations in the world around us.

This law doesn't depend on how we feel or think. It works the same for everything, even at the quantum level. If a molecule moves at light speed and comes back, it ages less, as if it's traveled to the future. The interesting part is that everything feels normal while traveling, the time ticks normally, but the real difference in time only shows up when you return.

Abs if your answer contains 'space-like' or 'time-like' phrases so the time is not a dimension.

So, by not understanding the topic ... you're qualified to rate it?

A study which was just published in the international journal Animal Behaviour, showed that small-bodied animals with fast metabolic rates, such as some birds, perceive more information in a unit of time, hence experiencing time more slowly than large bodied animals with slow metabolic rates, such as large turtles. I think that other factors that varies between humans also affects how we perceive time

This is the first time that I've heard spatial contraction at relativistic speeds is due to the "angle" at which we view 3d objects within 4d space-time. Fascinating concept.

The way I conceptualize it is essentially like looking down our world through various sized straws as we continue to accelerate. We start with a big gulp straw, boba tea straw, soda straw, coffee straw, until you’ve reached seeing nothing, which would indicate you’ve reached the speed of light. You’re narrowing off your peripheral view the faster you go, or in this case, closing your aperture to the amount light that travels with you.

The time is not relativistic and it is exactly relativity that has prevented quantum field theory from making any real progress! The truth is that time is nondimensional it simply doesn’t have any physical dimension whatsoever! That is to say that time is not a physical entity in any true sense and therefore geometrical concepts of time fall short or give answers that do not reflect the true nature of what is taking place, such as length contraction and other matters of that ilk. Even that theory suggests zero dimensionality of time when one moves at exactly the speed of light in a vacuum this reduces the destination time to 0 because one is perpetually suspended above the 1 dimensional surface of the destination. Clearly this is evidence that the mathematics is indicating something that just isn’t complete and therefore doesn’t work. Proving this would take many pages of complex proofs, however.. the math has already been done, it just isn’t public knowledge.

Maybe another thought: imagine the appearance of an object in 4D (just skip one dimension and imagine an object in 3D) and then apply this thought to space-time by just skipping one space dimension (just like in the video). Now imagine how objects would appear in that space-time. Imagine how you would appear as an 4D object in space-time (ok, skip one dimension so you can imagine a §D object). You would appear as a kind of bent and curved spaghetti, with one spaghetti end marking your birth (appearance in the world) and the other end marking your death (disappearance from this world) all aligned along the time-axis. Now of course immediately you can ask: is this object fixed or can it move depending on your actions. A fixed spaghetti means all your actions are predetermined, and you are just experiencing your actions that are already there. A movable spaghetti means that by your actions and decisions are not predetermined, and therefore you can change the appearance of your space-time object (your spaghetti) depending on the places you visit (depending on your actual movement through space-time) during your life. A movable spaghetti also means there must be another additional "time-like" dimension in which your 4D spaghetti can move. This other dimension defines then the choice realm or the choice dimension. So our world must be at least 5 dimensional, with 3 space dimensions and 2 time dimension.

It is happening all at once to some conscious. Time is relative.

One point: It IS possible to slow down the passage of time, as we perceive it. I can tell you that without a doubt. Sitting in the cockpit of an F/A-18 in a knife fight with an Iraqi Mig, I witnessed the passage of about 4 seconds take far longer. Time slowed to a crawl. That 4 seconds to everyone else became almost 30 seconds for me. I could see the raindrops deform as the swept over the fuselage of my aircraft. It was absolutely terrifying and incredible. Afterwards I felt like I had been run over by a train, my entire body ached from head to toe for days. I've pulled 9 G's many times and never suffered so badly. The adrenaline that my brain dumped into my system in those moments aged me about 4 months in 4 seconds.

I wonder if the stress hormone has an effect on recorded memory. If you are in fight or flight mode then your senses are heightened and perhaps the more primitive parts of the brain take over leaving the rational part to observe in high detail like a slow motion video recording. Perhaps this is also part of the cause of PTSD after stress i.e. more things are recorded in memory than during normal activity where we fail to observe an record and time passes quickly.

Incredible explanation! I’ve been thinking about this for over a decade and had the substance of what you described. The flatness of our experience in the 4th dimension was the essence of what I’ve been searching for. Thank you!

This is the most comprehensible explanation I have ever run across, thank you.

I like this explanation. It fits with another I like, which completes the picture a little: if we continue to imagine the Z axis as time, and X as space, the sum of the two speeds - spatial and temporal - equals the speed of light. So when you are stationary in space (arrow pointing up), you are travelling through time at the speed of light. Conversely, if you are stationary in time (arrow pointing right) you are travelling through space at the speed of light. If you tilt anywhere diagonally - so you are moving through both time and space in any distribution, the sum of the two speeds is always the same: you are just distributing speed from one to the other. And this sum is equal to the speed of light. Which implies both that everything is always travelling at the speed of light, and that the speed of light cannot be broken.

Enjoyed the visual way to explain this! Still not sure if I get it though :)

I like the description of 4D from Cixin Liu's book "Deaths End". He describes 4th dimensional objects as being vaguely comprehensible to 3D observers ( Assuming they are also in 4D space ). Analagous to the infinite tunnel effect 2 parallel mirrors make when reflecting each other, we'd see a silhouette conveying a "tunnel" of near infinite 3D topological information. Imagining a 4D cup of coffee: you'd "see" the information of every possible 3D perspective of the cup and it's contents ( layer by layer ) down to the resolution of the planck distance. All from a singular 4D perspective. The takeaway from this is that instead of imagining 4D objects as arbitrary "complex" shapes, think of things in terms of conveyable information as limited by perspective. A 2D person would have to change their orienation by rotating within X,Y to see things at a different angle on their plane. However as 3D observers we can see all concievable 2D information simply by looking down at this 2D world in the Z axis. A 4D observer would be no different, merely gazing from a direction that our spacial physiology prohibits us from being aware of. It's pure sci-fi that doesn't factor in time as Alex does here, but it helps put into context the incomprehensibility of such thinking as long as we exist within a lower dimensional framework. It also embeds how terrifyingly different beings of higher dimensions could be. Able to make sense of the most complex 3D structures imaginable as easily as we witness the wrinkles on a sheet of paper.

You may think more like myself, then, and would benefit from checking out Steven wolfram's computational understandings of things. He breaks down both space and time as essentially various different ways the universe processes information, and that is it. Seeing as we are a part of the universe, that is also true for us. What might really blow your mind is that linear time, as we experience it, is simply a byproduct of us being trapped within three spatial dimensions of existence. Beyond that, everything is occurring simultaneously, as if beings at that level of existence had such a perspective as to see you essentially stretching through the universe like a giant snake of yourself, from the moment you were born to the moment he died. Obviously, it wouldn't look exactly like that, but describing movement through the fourth dimension table language that is only designed by three-dimensional understanding requires even more sloppy shortcuts then language normally does, which is a pretty ridiculous amount, in the first place

If you expect the space expansion is consequence of moving in time dimension that could have any speed [m/s], than it means it is kind of a spatial dimense measurable in meters, but not kind of time dimense measurable in seconds. In that case you need any additional extra time dimension, because it expect the shape of 3d space in next aditional 4th spatial dim. where you can move in the times pace. Due to the fact the moving is not "single dimensional" function, it is fnc meters and seconds.

We had no awareness of our place in the 3D world, yet the moment we understood we realised we were already there, it simply became official, stands to reason that the moment we speak the language of higher dimensions fluently is when we find ourselves ALSO standing in the future, looking down into a wishing well.

This was so simple, but makes so much sense. Thank you!

i have a graduate degree from a good school but not in physics or cosmology. however, i have taken up those two areas of study as a "hobby." as to the existence of time, i had an odd experience recently. i have been down with a cold and flu and have been confined to bed with all the normal symptoms of those exceptional ailments. one night i awoke from a dream. in that dream, i was in a very large open warehouse room. there were not a lot of items in this huge space, just me sitting in a chair and various small tables some distance away from me in the dim light. as i was sitting in the chair, a thought entered my mind that i was existing in my own reality in that chair. off in the distance i could make out shapes and tables but i knew they were just "there" - they were not experiencing any changes or movement or "existence" as i was in my chair. i realized that there was no "time" for these other objects. whatever had been their state "in the past" was the same state they were existing in "the present" and that their existence would not change "in the future." "time" was not a concept that affected their reality. it seems to me that time is only relevant to living things on this earth. living things are born, and live for some period of "time" and then they pass away out of existence. but just because living things go through this cycle in no means requires that everything else in the universe needs to go through some "birth, life, death" cycle. what this would mean for the reality outside of "human reality" is that the past, present, and future all exist at the same time. try my thought experiment. imagine you are in a dimly lit large warehouse with a few items visible around. then think about what is going on in the space you are occupying and then "suspend" that thought and imagine the reality around all the other objects in the room if nothing at all is happening to the other objects. the universe and the quantum world may simply be a "reality" that is just "going on all the time." large space and quantum space are just active places where events are occurring but not in a "linear" manner but just in a "random" manner. humans exist in a linear reality but "our reality" is not the ONLY "reality."

How have you been on youtube for 16 years.

Excellent summary. A very tough topic to explain, which you did very well 👍

I believe that time is just a model we use to describe changes. It seems natural to think about time when you look around you, when you consider your age or anything else in life. But time is a really elusive concept. What you actually model with time is change. If there is no change, does time still exists? I believe that time, as we think about it, does not exist. We should think about changes and what drivers those changes. But maybe that is what we actually do with the 't' variable... I feel like we are missing something, maybe more conceptually than matematically. Time is something that relates, It describes relationship, It is the core or the nature itself of relativity. Imagine many particles, where each does not 'feel' the others, where there is no relationship. Would you tell that 'time' exists in that context? Sorry... just thinking 'out loud'..

From the right perspective, the singularity in a black hole would look just like the Big Bang. I imagine that the universe is like a big swiss cheese. Each local universe is the inside of the event horizon of a black hole in an outer universe, and each local universe contains a multitude of black holes, each of which contains its own local universe. The outer universe of a given local universe isn't larger, but all the black holes together form an network of black holes. None of these singularities are the beginning of the universe, but from inside they look like they are the beginning of their local universe. This network is eternal. I think of this as the Big Cheese Theory.

I don't know if the ones in the center and on the outside really exist or if they're just a consequence of the geometry of the six cubes "connecting" them. Sort of like if you were to spin a circle about an axis it forms a sphere, but does that sphere really exist? The way I was thinking about it, if you think about it in terms of faces, a square has one, a cube has six, and a hypercube has thirty-six. So I would think a 5-cube would have 216. What does that mean? I have no idea.

This was very clear in its explanation. Thank you.

Time is fundamental to how we think and understand. Instead of conceptualizing time as a direction, I consider it a description of matter. If that makes sense. The first three dimensions are descriptions we give to help us understand and relate to others, information about matter. On a graph where all spacial dimensions are compressed into an xy axis, i would use the time z axis to describe the change of the first 3 dimensions values. This allows us to reference things in the past, present, and future when we relate information to another. In this graph: At any point in the z axis, there will be a set cluster of values representing the 3 dimensional object you want to describe. Great thought provoking video

An interesting exercise in space time energy conservation. The way I always looked at it was a balance of energy. (space x time) = constant energy. If time slows or goes down, then space must increase in energy and vice versa. That change in energy is either by speed or gravity or the lack of. Thanks for the share Awesome!

That was one of my favorite shower thoughts. Another thing that I wondered about is at the big bang we were pushed in time very very fast, and we can fight against the speed at which we were pushed "forward" that is why time seems to be moving in only one direction. But if we can ever move in space very fast, close to the speed of light, moving through time would be easier. Also, this is the reason time feels like a different dimension to us, only because it happened to be the one we are moving the fastest through but in reality, it's just another direction that our brains interpreted as a different one, because it's the only one we can't change, YET. No scientific basis for anything here, but that is how I like to make sense of the universe when I'm alone. :)

I ve heard all these points before but never pictured them being brought together this way, especially time dilation being explained as a re-orientation in another dimension instead of just a simple length contraction is pretty profound.

What we refer to as time is a sequence of countless events that change the image of the universe and beyond. If we could reverse all these events we would be able to go back in time which is not possible, as it is also not possible to reverse entropy. Why is it possible in filmed events? Because in those we reverse all the events captured on film, but also (although not visible) all the countless events which occurred during the filming.

The faster we move in space in a loop (with acceleration) the faster we move into the future (the opposite of what the video explains)

without getting too technical, time is just a measurement of change... we use time as a way to measure entropy... and since information is always increasing, the universe is always expanding and time keeps going

@Liliquan

I know nothing of these topics but that’s usually how I regard it. I usually say that time is the measurement of the distance an object has travelled from point A to point B. I guess you could also call that change. But time would then be a singular and non-singular phenomenon depending on point of view. From the cosmic point of view time is the collection of all movement of all things simultaneously regardless of direction or distance travelled. From the point of view of a singular object, time is purely the distance travelled within set coordinates. So, I cannot comprehend this idea of time being a set direction that one travels through at varying velocities. And that one is being compelled to move in said direction. Unless that direction is the heat death of the universe. But in that case, how does velocity slow down entropy?

@avonlave

Totally agree... I have always said time isn't special, and isn't a dimension. All time is... is the measurement of change. The universe is always changing. Atoms are always moving and recycling. If everything was completely still and unchanging, time ceases to exist, because there is no distinction between one point in time versus the other. It's actually possible to time travel back to the past, all you have to do is reset all atoms everywhere to a previous state they once all existed, however, good luck finding the energy to make that happen. And how would you know where every single atom in the universe needs to be to get back to the exact same state. But even that wouldn't be real time travel, just a temporary duplication of a previous time, only if you could also determine and control the vector of changes for each atom to be identical to the previous state, then you have achieved actual (but not really) time travel to the past, where everything is the same AND heading in the same direction as it was before. Anyways, time is simply the measurement of change, and change is always occuring

I wanted to advise you that what you are currently doing is making comments addressing the video, but what you want to do (and should be doing) is replying to comments from other individuals on the video who are replying to you. To do this, simply select the person's name and click reply. You'll know you're doing it correctly if the comment starts with an "@" symbol, which KZread will automatically add for you. For example, if you were to reply to me, the message should begin with "@shkotzim_bacon," which is my username. Make sure the message begins with that, and be sure not to delete it; otherwise, the person will not get a notification of your response. Now, moving on to the rest of your message. While I agree that time may not be real in the sense that it's just a construct of our minds, it does indeed exist in science. In the field of relativity, time plays a critical role as a dimension and, when combined with the three dimensions of space, it forms a mathematical framework called spacetime. It's fascinating that you brought up the topic of mass changing the flow of time, which is actually a concept in general relativity known as gravitational time dilation. Gravitational time dilation refers to the effect of gravity on the passage of time. According to general relativity, the presence of mass and energy curves (or bends) spacetime. This curvature of spacetime affects the flow of time itself. In the presence of large masses, such as planets, stars, or black holes, time runs slower relative to regions with weaker gravitational fields. This means that clocks closer to massive objects would tick at a slower rate compared to clocks further away. It's a remarkable phenomenon that has been experimentally confirmed. To put it in everyday terms, this means that the higher up you go on Earth, clocks tick faster, and the time experienced by your feet is a tiny, imperceptible amount slower than the time experienced at the top of your head. On the other hand, kinematic time dilation, also known as time dilation due to relative motion, refers to the time difference experienced by two observers moving relative to each other at constant velocities. This effect is described by special relativity and is based on the principle that the speed of light is constant in all inertial frames of reference. An example of this would be the twin paradox, where two twins begin at Earth, and one leaves in a rocketship towards outer space. When they get back, one is older than the other. The paradox arises because it's relative to whom is actually accelerating - whether the rocket is moving away from Earth or Earth is moving away from the rocket is relative to each observer. Therefore, which one is older? The paradox is resolved because the twin on Earth is in an inertial frame of reference, and the twin, when he is in the rocket turning around, is in an accelerated(non-inertial) frame of reference. Therefore, when the twin arrives back on Earth, he realizes his twin has aged more than he has. If you'd like to delve deeper into the topics of light and relativity, there are various resources that can help expand your understanding. Some recommended resources include books like "Relativity: The Special and General Theory" by Albert Einstein or "A Brief History of Time" by Stephen Hawking. There are also numerous educational websites, lectures, and documentaries available on platforms like KZread or educational platforms like Coursera or Khan Academy. Furthermore, I am happy to recommend other videos and KZread channels if you're interested in that format and learning more. I'd be more than happy to answer any more of your questions or continue the conversation. Please let me know if you would like to explore these topics further. Best regards, Mr. Bacon

Anyway it is clear to me now that time is some kind of illusion. I heard the gurus talk about all events actually happening in the present moment and so that things we perceive as the past or the future are in fact happening simultaneously with that which we perceive as the present. This theory lines up with my experiences, and suggests I have had hints into these other realities. But it doesn’t explain how events in my dreams match up with events in other peope’s realities. It also doesn’t explain how my friend and I seem to be in my dreams together and based on things I then report to him afterward: things he knows about but I don’t (in our waking lives).

Yo girl that's cool. I just farted.

This is by far the best explanation and graphics animation of special relativity I have seen EVER. And I have had my PhD in physics for 32 years now. However, the title of the video is completely misleading, if not wrong! Anyway, thank you so much for an excellent video.

Maybe time moves through us rather than we move through it, therefore if you travel fast you catch up on it somewhat and it appears to slow down...just a thought, Gravity also seems to play a part in time dilation. The fourth dimension is a fascinating topic. Great video

No. We must move through dimensions. If you don't accept that, you can't even understand 3D space.

Time being a dimension means we can theoretically move in more than one direction through it, maybe it’s just our consciousness that moves through time from one moment to the next and these moments are just like individual still images that form our life movie. Everything is always still, frozen in time, and by moving through it we make it seem as if it’s moving around us. Time is a mental block.

That’s a good point. Why do we only move one way through time but move multiple directions through the lower dimensions? So maybe time is not a dimension? Or we just don’t understand how to effectively move through it?

@@andreshernandez1180See my comments on existence and existence+1 as units to comprehend the same as the time concept. But the existence principal sits on a foundation that everything in the universe exists together but may change independantly from each other. So everything in the Universe all exist in the present and are always in the present. We are all stuck in the present. It's the present that moves along the "Arrow of Time". This arrow is a concept again to try to help our "concept" of what the Universe is. However it is all theoretical but most of it works for local practical applications so I'm not knocking it all I think is no one is ever going to time travel as we are all stuck in the present.

Good job. Building models based on flawed or incorrect assumptions undermines the reliability of science. It's essential to acknowledge the limitations and inaccuracies in previous models, such as the variability in so-called constants. This recognition is crucial for advancing the pursuit of truth and accuracy in scientific understanding.

I should say, well done to both of you! What you guys put out has helped me 1000x more than what I learned at school. I understood Astronomy for the most part, my dad was a Science major in college and was a science teacher for a while, but I never had him as a teacher myself until I went into home school when I was 12-15 yrs old. I learn fast, but only if the teacher and I are on the same page, so to speak. I had trouble learning a bunch of things because I had a cyst that was compressing my brain, an arachnoid cyst about the size of a lemon, had brain surgery in 2005, but it took quite a few years to heal up, then started having seizures, it's been rough. No joke. I'm still kickin' though. I have an amazing son and I get to watch him grow up, that's all that matters, and being on disability means I have more time to focus on what I love and enjoy.

Time is an abstract representation of what happens. A representation that we need, just as we need the international metric system. And like the latter, time can only be measured by comparison. That is, what we name time is the result of a comparison, and in an abstract way we say 1 minute. Time is not an illusion, but a tool to understand everything that surrounds us.

It only seems like time slows down as you move fast because the way we measure time is with clocks and the hands of the clock, or electricity that runs thru a digital clock, has farther to go when it's moving fast.

I think about distance and time sometimes. It is facinating to think that the star we see in the sky now may have stopped existing as a star a billion years ago. Our future is the past somewhere else, and it is the inverse for that distant place. Just so interesting.

Great way to illustrate the time-dimension - thanks!

when I was a teenager, I got some extra private help math lessons from a friends older cousin. at one point we started to talk about religion, more specific angels. so I asked him "how can the angel of death by at so many places at the same time". he answered "because of the 4th dimension, which is time" (he continued explaining the details). this happened around 14-16 years ago. and until now I haven't seen or heard anyone talk about time as the 4th dimension, but I always had this is my mind.

Fantastic video and very clear explanation. It would be great if you can make another video to put gravity into your stickman model. I am still trying to wrap my head around gravity and time dilation in the context of the 4th dimension.

0:37 'What is time, you can't taste it, touch it or feel it.' But you can experience it, so many different emotions affecting you depending on the circumstances, like not knowing when it'll be your turn in a hospital waiting room, or in trepidation waiting on good or bad news, or trying to get a task done before a deadline, or rushing to catch the last train for the night, or wondering why that 10 minute snooze button buzzes after what seems like just seconds This is time when you are most conscious of it, when your body reacts so much to it.

Time is the 4th dimension because in 3d i can move up, down, left and right, front and backwards. But with time on equation, i can go back in time after moving to one direction and change direction at the same time. So with time i can move at all directions all at once.

@Av987

8 ай бұрын

That finite amount of something in my opinion is the universe constant of the speed of light. What it tells me is it that nothing can move faster, nor slower than the speed of light. When we are stationary in 3D space, we are moving through the time dimension at lightspeed. When we are moving in 3d space, the speed of light must be divided over the x, y, z and time axis. The closer we move at lightspeed through x, y and z, the less”momentum” can be used for the time dimension, thus the slower time passes. As for the question what drives the force that pushes us over the time axis, I believe everything in space is moving at lightspeed, it’s a given constant of the universe, it is impossible to go slower or faster than the speed of light. We can only manipulate in which direction we are going, in other words, manipulate which portion of the speed of light is used on which axis. If it’s a given that everything is moving at lightspeed at all times, there is no force needed, because only a force is needed to accelerate or decelerate.

@@Av987 This is an excellent thought experiment, thank you for engaging! I have a question regarding light speed and the movement of objects through time and space. Let me first preface by agreeing with you that yes all things move through time at light speed, however we can measure light moving through mediums at speeds slower than light speed. So I believe that it is an important distinction to make about the inherent speed of all things moving through not just time but space and how mediums slow this movement through space below the speed of light and to incorporate this differentiation into our thought experimentation and eventual theoretical models. So I'm unclear what your stance is on the speed of travel through mediums being slower than light speed and how this is incorporated into your thought experiment? Can you clarify this for me? Also, how did you come to the finding that the closer things moving at the speed of light, the less momentum? This isn't a concept that I have a complete intuitive understanding of and Im very interested in your thoughts on this concept.👍
