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.

As someone who is not educated in all of the physics and math needed to understand these concepts, I find this to be the best explanation of the dimension of time. Incredible work done here.

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.

At first I was like 'Silly Alex, you're going a bit too basic there with the explanation of our 3D world' and then this turned into the hands-down simplest, cleanest and best explanation of 4D space (and time) I have ever heard - bravo, Mr.! Also the book looks really great, congratz!

Wasn't this supposed to show us why time did not exist?

This video includes comprehensive pure details of space time that I have learned ever since. Congrats and thank you 😊

This is the first time scaling at relativistic speeds has ever been truly intuitive to me. I'm nearly 40, and I've been consuming physics media all my life. Thank you! It's been so long since something was new or different enough to give me that "ah-ha!" feeling.

This is absolutely the best visualization of time as a 4th dimension I have ever seen. Thank you for this!

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.

From waking up from a coma i can confirm this is exactly how i felt when i was gone for a week. Time didn’t exist, i was and still shocked how long i was out because i felt like i blinked my eyes to a tube in my throat

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.

I really like your explanation really helps. The challenge in understanding is that from 1d to 2d and the 3d, we analyze in terms of space. That's perfectly understandable. The challenge is that going to higher dimensions implies introducing things like time which are not spacial per se

Excellent description! Great insight. I only had to rewind 2-3 times to comprehend! That's pretty good for me!

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.

I've always had trouble comprehending the theory of time and space relativity before, but your explanation really broke it down so well that I've finally grasped it! Thank you so much for your detailed, in depth graphs and animations!

one of the best explanations, as of now, providing a great perspective and clarity. 👍🙏

I perfectly understood 4D up until time. I was curious about what does time have to do with it. When you rotated the stickman in time it made all sense to me! This is amazing

Space and time are relative, the more time I spend with my relatives the more space I need
