What do you wanna see Neil explain next!?

I never know what I want explained until I hear him explain it.

I like Chuck's closing statement... _"In another dimension, we'd have all the time in the world."_ ...That is profoundly astute.

This video was brilliant. The writing, visuals, and audio were all masterfully done. Thank you 🪐✨

Love it! To go from not understanding to understanding. Lightbulbs turned on. Thanks Neil, science, sense, humor all at once.

The ability to turn a complex concept to a comprehensible one is truly astounding. Such a master teacher.

10:28 "In another dimension, we would have all the time in the world" That's some lowkey 🔥🔥

This is a great simplified teaching on dimensions, love it!

Wow! That was very informative! Answered questions I had in preparations and advanced testing of delicate components before launch time! You guys got this! Thank you, Leo

2:50 Chuck's got a point, in the digital space people need to meet at the same time, but also in the same digital location. Whether its a URL address or some server, the computer and its code is just an extension of your body at that point. An extension that can interact with the digital space.

Summary Forward and backwards = 1st dimension Left and right = 2nd dimension Up and down = 3rd dimension In the Past and to the future = 4th dimension In simpler medical terms The length of the body = 1st dimension The width of the body = 2nd dimension The skin or outer layer = 3rd dimension The ability to see through everything especially through the skin = 4th dimension. This is the most beautiful thing I’ve learn from UKposts.

I’ve been trying to wrap my head around the 4th dimension explanation for the longest time and this video is the closest I’ve gotten to truly grasping it! So cool! Thanks Neil!

The way Chuck passively absorbs Neil’s science talk is probably the best part. They make a great pair lol

Does anyone one else get the feeling that Neil deGrasse Tyson is possible a truly brilliant stoner ... Bc this is the kinda stuff that pot heads contemplate.

Chuck outsmarting Neil by pointing out virtual presence! Loved the way Neil looked, he surely didn't expect that!

Neil...you are the best scientist of our time for us laymen. You break it down for us and make it not only mentally digestible, but entertaining. Thank you 🙏

"We are prisoners of the present.. forever transitioning between an inaccessible past and unknowable future". 🔥

As a bicycle commuter who has given a great deal of thought to traffic interaction, the image of me and a truck occupying the same space at (hopefully) different times occurred to me long ago. Many cyclists want separated bike infrastructure to protect us from motor traffic. But the intersections are always the hardest part. By definition, intersections are where people’s world lines can intersect on a road. So if you want to separate bikes and cars at intersections, there are only two ways: space or time. Either add a third physical dimension in the form of an overpass or tunnel, or control the time dimension with a separate green phase. That’s it.

Neil! I just want to comment that one time my mother heard you say that colds and flu is caused by viruses not by temperature (cold weather) and in her eyes it completely discredited you as a person of science to her and I find it exponentially hilarious. I love and admire your work. Thanks for existing!

How did I discover this channel just today? Subscribed immediately.

I remember when Picard dealt with 2-D "beings". I found Data's intel rather interesting. He mentioned the Enterprise D's forward sensors could not detect them, and he used additional probes to scan. And this now links my memory to scanning space back in Eve Online using multiple probes, which scan in a sphere. Each sphere covers an area, and when the scans overlap, you get interesting results. Move them around alot, changing scan strength, etc.. Generally, the more probes,.. the better. But not needed. In space, I suppose you could find something with just one probe, but it's going to take a very VERY long time. But when your using 3, 4, 6, or even 8, your covering tons more. Fun stuff.

"very low bar" I was thinking the same haha. I agree with Neil in that the subway and the cars on an overpass are existing below or above the original flow of traffic, but all of those vehicles can still only exhibit two-dimensional travel. the cars on the overpass aren't flying, they're just traveling on a parallel planar surface. and of course, the two-dimensional travel I mentioned isn't truly two-dimensional, because vehicles *can* travel up and down as long as the surface they are traveling on curves up or down, though we wouldn't consider these vehicles to be flying either. I don't think I've watched any videos from this channel before, I'm glad I stumbled across this one. a little mental stimulation on a sleepy Friday afternoon at work has been quite welcome!

This is why I love "Flatland" by Edwin Abbott. That was the first time I could ALMOST get a feel for a 4D being's view of the world.

Great explanation Mr. Neil! We must not also forget that time is relative. Each of us experiences time differently, depending on the level of vibration we are in and vibration consists of our memories, thoughts, emotions, beliefs, behavior, and traits which can be characterized as either good or bad. Higher vibration = empathy, compassion, kindness, transparency. Lower vibration = everything that is opposite to the ones mentioned above. 🙂 Thanks a lot for your video, Mr. Neil. 4D surgery, that's an amazing idea.

Man these two men are genuinely hilarious together 🤣 nothing feels scripted or forced in any means lol. They aren't try hards, just for likes, views etc. I love this content.

2:47. Chuck's intervention, …silence. It was good to point it out about a virtual reality that is quite real in another "dimension". Nice.

"You have a very low bar for what's called a flying car." We can always count on Chuck.

Teachers are so very important, excited to learn is a gift very few have to give

Great video! This is getting super interesting!

"We are prisoneres of the present forever transitioning between our inaccesseible past and an unknown future..." What a beautiful thought...and as always just amzing episode...fun and learn both😊😊👌👌Lots of love and respect from India Neil and chuck...

wow loved the explanation really openned my eyes, keep them coming

You two always bring a smile to my face ❤

“We are all inmortal spirituals beings living a human experience “. Nice episode !🤙

At the age of 55, my mind is drawn toward the wonders of the universe. I would have to say you are one of the most intelligent human beings, yet you can convey your knowledge so that an average dope like myself can appreciate and almost comprehend it. I've just become a fan but I have yet to watch a boring podcast with Neal on or hosting. Wish I did not wait until so late in life to learn these fascinating facts about our universe.

Brilliant! Will share this with my students

What an amazing lesson 😀. Thank you both.

Neil and Chuck never fail

Flatland I remember having to read that in my Linear Algebra class in college. I was always doodling in class. While in Linear Algebra, I drew a 4th dimensional cube on a 2 dimensional surface (a piece of paper). It didn't look like what we typically think of as a cube. It looked like a spherical diamond with a lot of facets. It was actually pretty cool.

Carl Sagan explained this beautifully on Cosmos. Neil has done it brilliantly, too, though. Keep the great videos coming. Neil is a living legend.

so teleportation would require access to the 4th dimension

I never ever get tired of these 2 gentlemen

I personally absolutely love the animations going over what you’re saying!

This is one of the simplest explainations i heard on dimensions 👌👌

That was probably the best explanation I've heard of 4 dimensions

Always fascinating and thought-provoking topics to enjoy. Thank you so much StarTalk!!

One small suggestion to the editing and animation team: This time the animations wasn't able to capture what Neil was saying accurately. Especially in regards to seeing a 2D body in a 2D world and the "dimensional" surgery. Either they didn't understand what Neil was saying or they don't have the technical know-how to make it. My bet is on the former, because they seem very skilled otherwise. Lots of love to Neil and Chuck and the team of StarTalk. You all make my day a 100 times better ❤

My friend and I discussed this topic all day long, I'm glad we weren't far off the distinctions between dimensions

so 4d is just Minecraft spectator mode

About 35 years ago, I watched a lecture given by Thomas Banchoff. He had a series of computer generated films (really a big deal at the time end of the 1980ies!), which were 2+1 dimensional projections (two dimensional plus time) of movements in higher dimensions (mostly 4+1, but also some 5+1). What really impressed me at the time was that after watching them for a while, you really had some kind of four dimensional vision. Seeing a 4-cube rotating appeared no longer as some flattening and morphing of interlocked 3-cubes, but became a fluent movement of a single body in four dimensions. So my impression at the time was: We would be able to see four dimensions, we just don't get the right stimulus for our eyes and brains to process.

You can't fathom the enormity of how much I love this podcast.

Wow this is so well explained! Thank you!

That is the most interesting and fun explanation of hire dimensions I've ever heard

This video reminds me of one of my favorite books, "Flatland: A Romance of Many Dimensions" by Edwin A. Abbot, and all of this made me think about entangled particles, and how they could defy our notion of being close, acting as they really were, when they are instead so distant. Are they maybe close in another inaccessible (to us) dimension? Or we share the same dimensions as the entangled particles, but we are very thin in that dimension; we are like people living on a sheet of paper, while entangled particles can move as they want in that dimension.

One of the earliest books I read which I can still remember was called startalk (I don't know if it's the only startalk book or not) and I just recently found it again, Neil you have been an inspiration to me since I was a child, thank you for everything you do.

These two compliment each other so much! Humor and intelligence. From both guys! Love em!!

I haven’t seen this wonderful channel since before Covid!

2:44 @Chuck, on the live Zoom call, you are kind of in a state of #superposition; existing in 2 spaces (digital & physical) simultaneously. So, you made a good point/observation there, sir.🫡 Perhaps we need to start viewing the online space as a dimension (a virtual one), which essentially would make us 4th dimensional beings even if the other dimension is one we created.

One flaw, he said we will be a prisoner of the present. But there is nothing besides this ever-lasting moment which is NOW, ever is, and ever will be. Even if you go to the future or past you will still exist in this moment now, you cannot escape it, everything exists NOW.

I have trouble fully accepting time as the 4th dimension. If a 4D hypersphere was to cross through our dimension, you would see a sphere growing and shrinking. Similar to an MRI scan, which has 2D slices which represent a 3D object. A way you can understand more is by using shadows of an object. Take a hollow cube, which just has edges and vertices, but no faces, its shadow would show a tesseract, but a 2D representation of it. That's why I find shadows very interesting because you're taking a 3D object, to create a 2D representation of a 4D object 😂 But none of this uses any time whatsoever. Time could possibly be a 5th dimension, but in my opinion, size/scale is the 4th dimension. This could still be interesting because say you have a chocolate bar, and you pass that through the 4th dimension, you can increase its size and have a chocolate bar that lasts virtually forever (before it goes off). I suggest you play around with hollow or transparent objects with shadows, and it'll trip you out lol

This leaves me with more questions 1. “Fourth dimension allows you to go to the time before you got locked in a cage. “ Would that mean you can avoid what’s coming even though it has happened? 3. It enables you to move to the future, does this only apply to your perspective? I’m not sure if this video debunked fourth dimension for me

6:35 I would posit that the "present" does not actually exsist. If you really think about it, there is only the past and the future. We only have the "present" in the colloquial sense.

This is something that I've been talking about for many years. To see Neil finally tackling this aspect is really encouraging!

Shortly: We as 3D humans can see everything in 2d worlds. Like a drawn stickfigure is 2d, we can see inside it’s head and inside a 2D house. So a 4D being can see inside our 3D heads and houses without needing any windows or doors. Scary thought

Every time I listen to Neil, I feel a little bit more awesome. Thanks bruh.

Thanks lads struggling to understand this correctly for years, this helped a lot and pleasure to hear you both. Subbed and shared xo

I too believe Chuck has a point. If zoom is a platform where we all meet, than that's our virtual location in the virtual space.Also, we are in different time zones , so we are meeting at relative times not the same time. Which might also mean that we are not meeting at all. We are just responding to each other's recorded audio-visual representation in almost real time. I am saying this is a a topic for one whole episode, it's up to the great minds to take it up.

I thought our comprehension of the 4th dimension and higher dimensions we’re referring to *spacial* dimensions exclusively. For instance, in 4th dimensional space there is still an additional dimension of time. So any higher dimension is always +1 (time). Certainly time can be thought of as a dimension, and Neil does a great job here of explaining its importance, but I think it’s important to differentiate what we’re referring to, spatial vs temporal.

“OK, let’s keep talking about dimensions, ready!” 😂😂 that has to be the most funnest tag lines I have ever heard on star talk. 2:43

If beings that are 2D have even the thickness of on atom, then they would be 3 demintional. Nothing can be 2D unless it doesn't have any thickness at all. Is there any matter that doesn't have any thickness?

I'm so Loving This!!!! Thank you Neil & Chuck!!💛💫💕👍👍

I audibly said “oooooooooooooh” when you explained unraveling a 4D knot….you guys rock

This is really interesting and he explains it so well 😊

Dr. Tyson, you always find a way to blow my mind. Thank you for this new knowledge!

Thanks, Gentlemen! Superb as always.

Very nice explanation🙏🙏🙏❤❤❤... I needed that.. 😮

Not gonna pretend I understood the whole dimensional surgery thing.

Finally the ELI5 version!!! All the other explanations are as if you already understand dimensions. Love the way Neil explains this here because I've watched countless of his interviews and this is the best yet.

Neil! I am convinced that time is a fourth dimensional property that permeates our 3d dimensional reality and we only see it passing because it cant be fully formed in our dimension. This suggests that the fourth dimension is infinate (time ceases to pass) Photons therefore are simply 1 giant 4d object intersecting our 3d realm, we can only see them as individual particles, so they appear to be moving, and limited in our dimension to the speed of light. (the maximum velocity our dimension can accept before collapsing into a lower, or breaking into a higher dimension) < is this plausabile?

I saw an episode from the original Outer Limits about a being that existed in all 4 dimensions. The creator of that series, Leslie Stevens, had a physics degree. Which sometimes makes the show quite smart. He doctored the scripts with particle physics, as the series' inhouse science advisor.

This was why the movie Arrival clicked for me when i first saw it. They experience their life circularly all at once. The Cephalopods were 4 dimensional beings. And they introduced their "language" (understanding of time as a language) to us

Thank you Neil for breaking that down, I watched another video which lead to more questions and then stumbled across this video .. The first one NOW makes sense !!

That was a pretty awesome explanation! I always wondered what they meant by time being the 4th dimension. It finally makes sense.

My "bucket list" tour 🎉

Did he explain string theory at 8:21? Where the knots and loops of a string of energy create the building blocks of our 3D world? Light = wavy string, Rock = knotty string. Different types of knots = different particles with specific characteristics. In 4D, these knots would be simple to understand and manipulate, "...just pull the ends!" . 4D sees the string as part of a ribbon. 5D the ribbon is part of a rope, 6D is braided rope, etc. I'm no scientist, but its fun to think of the possibilities!

Dr Tyson's delivery keep's me wanting to know more

@StarTalk @Neil Sir, can we consider the possibility that time is not the 4th dimension? My thinking is that time is a dimension that can be applied right from the very first axis/dimension. It is globally applicable. In other words, even if we were two dimensional beings, time could've been a dimension that can get applied. Also, a majority of things that happen in nature get unanswered if time becomes the 4th dimension. So, it would be great if you could share some thoughts on how time was decided as the 4th dimension. Just curious to know. Thank you for sharing this video. Beautifully explained, as always.

Reminds me of Carl Sagan explaining Flatland, so awesome and very informative!

There's something very therapeutic and calming listening to Neil talk. If you want to watch something very very interesting, I highly suggest watching ' What the Bleep!! Down the rabbit Hole' Thank me later! Peace and Love to you all! 😁

Gotta love this man and his passion for passing on knowledge

I love Chuck’s comment that with Zoom we converged at the same place digitally. Neil looked stumped for a moment and moved on after making a weak point to answer Chuck. Economists (and probably others) use multi dimensional modelling. Subways don’t utilize a third dimension as they can only go backwards or forwards. They cannot go up or down or left or right.

Listening to him explain it this way made me realize that the transportation of people and things increases exponentially when you have access to the next dimension. For example, a road (2 dimensional travel) people and Cars move one behind the other or side to side. But on the subway way (3 dimensional transportation). The car is larger, trains move one behind the other, side by side, above or below eachbother and so you can transport orders of magnitude more people than the road. On zoom (his idea of 4th dimension travel) you can have orders of magnitude more people than the subway,since you dont need to be in the same physical space (or even the same time if its a recording). Someone please look into this.

I could listen Neil talk all day, but I don't have the time like in other dimensions.

Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an ENTIRE CITY, with NO INTERACTION with each other, until they used the subway, complain about the same time paradox unless it was effected by it? Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? 🎶Ti-i-i-ime, is on my side. Yes, it is!🎶 If you can think of a better way to do a blind survey - of an entire city - in that small window of opportunity, well then, I'm all in. Until then, I invite you to spend a couple years in the subways. Between 2pm -10pm and you'll see for yourself. Just listen as an entire city gets off of work and gets out of school. You'll see it's more than a, "coincidence of circumstances." ;-P

Love it, that was fascinating and funny talk on dimensions. Neil and Chuck always leaving us wanting more.

about 3 minutes in, Chuck Nice still made sense. Our physical location differed as Neil tries to emphasize, but the digital location was all at Zoom! As Chuck pointed out. Not one at Facebook, the other UKposts, etc.

I love these guys 😅entertaining energy hehe & informative content

There are so many questions in my mind after hearing these concepts. I have been fascinated with the concept of time and space for a long time and time as a dimension seems complex and mostly incomprehensible to me. There are still questions which I would like to know the answers to. First: If we, the 3D beings are prisoners of the present which means we cannot traverse the 4th dimension freely. Similarly, the two dimensional beings are also the prisoners of the present as well as the third dimension. Because they are also flowing in a single direction of time which is from past to future. Accessibility to the 4th dimension for both 3D and 2D beings seems the same. Of course we are faster because we can access the 3rd dimension...otherwise we all have the same experience as the 2D beings. Second: Can the flow of time be different for people...because as you know...the existence itself is highly dependent on that singular dimension of time without which there is no flow and hence on interaction, no entropy and hence no existence of anything. Third: If we take away the time dimension from the 2D beings will they be as they are or they will cease to exist, just like a static drawing like pausing your TV when you want. Fourth: Is there a possibility of a 2D world being separately existing outside a 3D world...suppose...there is a world where only 2D beings live...and if that is true... wouldn't they think that for them...the third dimension is time as we have deduced for ourselves. There are other questions still ringing in my head... I can't understand them maybe someday I will be able to learn some maths which will allow me to probe them...Now I can only hope to get the answers from you sir. And also...you have been my childhood hero from the frist time I saw your premiere of Cosmos on National Geographic Channel. So please if you can relieve me of my torment....I want to know that's all.😊 If you read this I will be happy. 😁 But I still want to know

The ending... Splendid!!

So this is something I hypothesized many years ago. And before I watch this video I will make my statement. A 4th dimensional being would see an object in its totality. Technically we live in a 3D construct yet we see in 2 dimensions (that is why we can trick our mind with art that has perspective. Time doesn’t exist as we know it in the 4th dimension as everything exists all at once. So similar to how we can look at a dvd and the whole story of a movie exists in the DVD, in order to experience it we have to add the element of time which means you have to spend the hour and a half or whatever to watch the show, but the whole story exists all at once in the DVD or MP4 file.

Came here to learn about dimensions. Ended up thinking about dimensional surgery and a clear explanation of Last Epoch gameplay. 10/10
