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.

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

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.

We are traveling through time at the speed of light is a tremendous insight!

[@ryancook1873]

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.

[@cellphone6482]

I think this video is intentionally misinforming the general public. I think they mixed up how speed is not time, perceptual time is a conscious concept and not a strictly physical concept.

What if the direction of time is the effect of universe expansion? Or perhaps, the force propelling you through space is the expansion of the universe, as the universe expands, even if you are standing still in space, space is "moving" around you, hence your "movement" through time. Your relative position in an expanding universe is always changing.

[@groovejet77]

So time exists because of the big bang and we must be in an infinitely expanding universe. We could be moving close to the speed of light without knowing it relative to a stationary object but then again what is stationary? If we are both flying apart at half the speed of light then each one looks like they are travelling at light speed to the other yet the effects of relativity wouldn't be observed. Maybe there's no such thing as a stationary object.

[@Sirvlaric]

@@groovejet77 I tend to think that there is no such thing as an object that is standing still. More than moving, I think more about each object's reference point in "space". Because space is expanding, your reference point is constantly changing within that ever-expanding space.

I think your brain fell off when u crossed a "wormhole" in your own mind.

[@M4R479]

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.

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'm interested in our perception of reality in this case.

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.

[@lefthandedelite]

Whoosh. Everything IS happening all at once, its just our perception that its not. That was kind of the whole point of the video.

[@aaronnathaniel9135]

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.

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.

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.

[@castonyoung7514]

That is correct falling is a result of spacetime being bent so that our direction of time is angled toward the center. And I believe a black hole is where space has finally been bent at 90 degrees (well between 45 and 90 degrees).

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]

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]

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 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.

Great vid. Couple of points - 1) a sailboat can travel faster than the wind pushing it because it has a keel. Sailing is more like squeezing a pip out between your fingers. The wind pushes one side, the keel pushes the other, and the boat gets squeezed out between them. Thus, sailing directly in line with the wind is not the fastest you can go. Boats can also tack. That is sail forwards against the wind direction. 2) motion is relative. For the person on the left, the person on the right appears to go slower in time as illustrated. However, it is also the case that the person on the right sees the person on the left going slower in time too. For the person on the right, their clock is still ticking at the normal speed, and it is the person on the left who’s angle has changed and thus appears to be going slower in time. It’s more like a symmetrical divergence than a one-sided thing. 2b) There is a hint of the ‘twin paradox’ here, where the person on the right goes away, then comes back and has aged less. You could argue ‘motion is relative’ and make the case that from the person on the rights view it is the one on the left who travelled away and came back. But that is not the case, as the one on the right engaged in what is known as non-inertial movement ie acceleration. It is that effect that makes one age less than the other. Hope that helps!

You are an excellent speaker in your video, which is well paced. You remind me of Brian Cox, who also studies and lectures on cosmology. I've long understood time in the context as you mention, and also I expand on that in the sense that "numbers" do not exist on the "number line" but are units of measure humans (and it seems some other species) use to count sets of objects or measure abstractions, such as the volume under a curved roof, and so on. I did not really enjoy math until I took trig in college, and later studied calculus, and finally computer programming which allowed me to practically use math (in my case, designing free art programs for children and adults and as a systems accounting instructor). You've won a new subscriber to your channel--you speak to your audience at just the right level, using analogies that make something that has baffled teachers, like myself, in explaining, since time measurement is very important in some applications of systems programming.

[@CharnavinT.Charnuvanik]

I appreciate the break down in this video with the graphs. For me, the image that comes to mind when thinking about time slowing while movement increases is one of resistance of the two directions, like they are fighting over a finite amount of something.

[@Av987]

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.

[@stephencarlsbad]

@@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.👍

@@Av987this model does make complete sense to me. But I have one question… what if we want to travel maximally through time and not through space at all? Is there an “absolute” origin of space time or does every individual thing have a space time axis of its own?

How do we know if we are actually not moving through space if there are no other objects to reference?

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.

[@stevenhoffman-cq6dp]

THANK YOU! Finally someone got it. I started working on this concept in the early 90's when in college. I would say the only thing you are missing is that 3-D space is curved. Your 2-D representation of 3-D space is actually like the surface of a sphere, rather than a plane. Space is also expanding. It is expanding through the 4th dimension of time, which is why we feel time moves in one direction. Now, if you move your 2-D person along the surface of that expanding sphere, you easily how he "relatively" moves slower in time than a person not in motion. If you look at the distance traveled along the same vector in time, the person that moved will have traveled less. It is the curvature of space that causes the time dilation. I also agree that the theory implies that space is expanding at the speed of light. This is not what we "measure", but that is due to the fact that we are measuring within the space and not within 4 dimensions. Also, the curvature explains why objects further away are moving away from each other faster than objects closer. This is the first time in over 30 years I heard anyone say anything close to my ideas, and you pretty much nailed 95% of it. Congrats on thinking outside the box.

[@thoughtsfocused2262]

This idea of dimensions is a misconception. There are no discrete dimensions as all matter has height, length and width. Nothing can exist in only one or two dimensions, if something has any one geometric value, then it will inherently have all three geometric values. That makes the concept of a fourth dimension based on a logical fallacy.

[@christ9467]

Lower dimensions are not “real.” That is true, but to say the idea of it is a misconception or fallacy is misguided. Dimensions as we know them are inherently in the abstract, besides the third where we exist. These abstractions do add value to our understanding of the third and hold as absolute truths. All of geometry that you are taught in school doesn’t exist in reality, but it does have real, measurable and applicable aspects. To use this same reasoning with higher dimensions, they may not exist in reality. But still an understanding of these as abstract concepts could add value to our understanding of what is real.

Yes, true.

Personally, I think the Cosmos is a total mystery, despite our boasting about it's size and it's 'birth'. I beleive it is eternal, no end, no bedginning, just IS and that it is 'made-up of dimensions we haven't discovered yet..i.e. that has made us hard wired to being conscious of it as a living entity since the beginning of human existence. .

Great video. As one who has done much research into the subject myself, I find the concept of time as a fourth dimension to be particularly compelling. You ask in the video what force, or "wind" pushes us through the dimension, as we cannot control it, and are at the mercy of it's power. My theory is this: science has long held that all objects in the known universe are expanding outward as a result of the Big Bang. So, all the galaxies are being pushed, if you will, ever forward from the site of the original explosion that began the universe. Therefore, the force, or "wind" pushing us through the fourth dimension, or "time", is the exact same force which is pushing the universe and expanding it outwardly. Time was created by the Big Bang, and we are reluctantly along for the ride, moving forward along with the stars of which we are a part. As the brilliant astronomer Carl Sagan used to say, "We are star stuff". This explains why light and speed are components of time dilation as explained by Einstein in the theory of relativity.

Question: If time slows down the faster you go, will it slow down to zero and go negative--back in time?

[@michaelzoran]

Excellent work. This is a very impressive video that explains the concepts of Relativity and Time Dilation very clearly. The fact is, we all have a "Constant" rate of "Motion" that is equal to the "Speed of Light." That "Constant" rate of "Motion" is divided between "Space" and "Time." If we are 100% "still" in "Space" and do not move at all, it means we are travelling through "Time" at the maximum possible rate of "Motion." As we move faster through "Space," the higher rate of motion causes us to move slower through "Time." If we travelled through "Space" at the "Speed of Light," which is the maximum rate of "Motion," it means this speed would be subtracted from the "Constant," which would leave zero through "Time." As a result, "Time" would have no effect on us at all.

​@@NoX-512 An object of ""Matter" contains so much "Mass" that there is not enough "Energy" in the entire universe to make it so the object of "Matter" could reach the "Speed of Light" according to the formula e=mc^2. The only reason photons move at the "Speed of Light" is because photons contain virtually no "Mass." This is sort of like cheating in the equation of e=mc^2, because you are in a sense multiplying by the "0,." This essentially means that because there is virtually no "Mass" in the object, it means there is virtually no "Energy" needed to move the object. It has been proven many times in a variety of ways that the "Speed of Light" cannot be exceeded in normal Physics. For example, if a person on a train throws a baseball at 50mph, another person on a train measures the baseball at 5mph in that frame of reference. However, a person standing still in a different frame of reference off of the train measures the baseball at the rate of 100mph, because the ball is thrown at 50mph and the train is moving at 50mph. But, this changes if light is measured. on the train,. If a person turns on a flashlight on the train, the photons would be measured at the "Speed of Light." However, a person standing still off of the train in a different frame of reference would not measure the photon as "The Speed of Light plus 50mph." Instead, the photon would remain at the "Speed of Light." This shows the "Speed of Light" is the maximum speed possible in the universe.
