    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.

      This explanation has a problem: why the person who remains younger due to travelling near the light speed (you say just one second younger) don't see the other older person 300 M km away if the time is a real dimension, and why we can not move backward in it? Abs if your answer contains 'space-like' or 'time-like' phrases so the time is not a dimension.

    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.

      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.

However, to all of my friends (bless them!) both time & space had moved quite normally, if perhaps a bit uncomfortably.

    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.

      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.

      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

    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.

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.

    Stretched between the past and future, but have not extended far enough in the future for time to be visible. Like this very informal presentation, and our manner of iterating/refining subjects in general, it seems that our means of extension is but a language barrier. 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.

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.

      What's amazing is that you can see inside of something if you are in the fourth dimension looking at a three-dimensional object, this is what always amazes me and in the book they have to be careful not to move somewhere and accidentally put their hand through someone or even through themselves.

      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.

      Side note: I feel clocks are an antiquated way of measuring time. Its not really a good way for humans to measure and perceive time. Thinking about how we divide time into a working day, should really be a way to measure the energy we can spend moving through space.

    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."

    • @Liliquan
      @Liliquan ปีที่แล้ว +1

      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
      @avonlave ปีที่แล้ว +4

      Yes but why does it change based on speed through space? The fact that it's not an absolute constant is what's puzzling. In other words, if time=change, why does increased speed cause change to occur at a different rate?

    • @ryanj2768
      @ryanj2768 ปีที่แล้ว +3

      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

    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.

    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?

    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. :)

      Also, as far as imagining four spatial dimensions, you CAN imagine what a 4D cube (hypercube/tesseract) would look like if you unfolded it. Just like a 3D cube unfolds into six squares, a 4D cube would unfold into six cubes.

      @@angelxenmai4413 Hmmm... I don't know. I just read that in a Brian Greene book.
      The way they try to represent these things graphically there's a cube in the center, each of its faces is part of a cube, and there's one on the outside. 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.

    I like to think about it as similar to a 2D animation movie. In the same way, each frame of the film is just a two-dimensional slice of the whole thing, I think about 3D space and the world we experience is simply a three-dimensional slice of a higher-dimensional universe. It's like a 3D frame of a movie. Time is basically the frame rate that this 3D "movie" is being played back.
    If a sphere passed through a 2D plane, the cross-section would be a dot expanding into a circle until it gets smaller and disappears again in a single point. I can't see how the Big Bang isn't the same thing as that, just in three dimensions.

    Thanks Mr Bacon. Such a warm response. Yes I know nothing about the science of time or light. Just what I see on YT. It is fascinating. There seem to be some that agree time is not a dimension. I tend to agree and think that time can be different when one is moving faster or slower or near objects of great mass that bend space and so effect the time taken to travel between points in space. Just the measure of the distance between events not a dimension itself.

      Dear Mr. Carroll,
      You're very welcome! I noticed that you were addressing another individual named Christian in the comments, but not replying to him in the appropriate way as you would on TH-cam. 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 TH-cam 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 TH-cam or educational platforms like Coursera or Khan Academy. Furthermore, I am happy to recommend other videos and TH-cam 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

    I used to be fascinated by information like this, but over the years, I became less interested in these topics, because after realizing our Human minds seem to be designed to not completely understand it all... almost like we weren't mean to. So now and days, whenever I do watch these kinds of videos (which is rare), I just enjoy the video. Great video 🙂

      You have access to one human mind. That mind has made the choice to not spend the energy required to fully understand this information. A reasonable choice given that understanding this information is not an imperative for survival. However, it is an error to generalise your choice to all minds. There are some who have the ability. and the curiosity to drive that ability, to understand. I applaud them although my interests lie in other directions.

    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.
