It's really hard. We can only imagine x, y, z dimensions. if we add w dimensions, we can't really imagine it. Maybe 4D entity see its 4D world in 3D image. Just like us see our 3D world in 2D image. When we imagine 4D world in 2D image, no matter what, it just can't as precise as 4D entity imagine it.

"If you were placed into a higher dimension could you handle it emotionally?" Great question Mr. Tyson. People these days struggle with simple internet comments which they don't even have to read. I say they can't handle it.
If a caterpillar which is a 2 dimension can transform into a butterfly to understand and grasp the 3rd dimension, I don't see how we humans have to inability to grasp and understand a 4th dimension. We just need something to transform us like how a caterpillar transformed into a butterfly. We already know the 4th dimension is there. Evolution is probably the transformation we need. Religion is probably 4 th dimension which we can't comprehend but have the ability to feel it.

The concept of higher dimensions, often visualized through the idea of a hypercube or tesseract, extends our understanding beyond the familiar three-dimensional space. A hypercube is a four-dimensional analogue of a cube, representing how objects might exist in higher-dimensional spaces that are difficult for us to visualize. This exploration of higher dimensions has profound implications in fields like string theory, where additional dimensions are posited to exist beyond our perception. How might the study of higher-dimensional shapes like the hypercube enhance our understanding of the universe and the fundamental forces that govern it?

Dr. Tyson, First of all, I am a big fan of you and all you do to make people of all ages understand and love science, and, by extension, math. Thank you! I would like to share with you an observation of how a 2-D world (ant) experiences its interaction with a 3-D world (sphere). I am quoting you describing this interaction. "...If we are ants on a sheet of paper living only on that 2-D, flat world, and we take a sphere and pass it through that sheet of paper, what would that look like to the ant? The ant would say, wait a minute, there is a dot, oh, the dot just became a circle..." The way I see it, the ant, first of all, wouldn't be able to distinguish between shapes: circles, squares, etc., they would look similar since the third dimension is missing to tell where the edge is moving, for example, in a 90 degrees direction as the one of a square. Secondly, the ant would notice something appearing out of the blue coming toward it. The ant has no choice but to retreat to avoid a collision. After a while, the thing starts running away from the ant, and assuming that the 2-D ant follows it, the said something will disappear the same way it appeared in the first place. The perception of a dot, circle, square, etc. does not exist in a 2-D world, unless our 2-D ant is brought up in the third dimension and is looking down on the new, strange phenomenon (the sphere passing through the sheet of paper) to see the dot and the circle(s). Thank you for giving me the reason to think like an ant, and share my observation with you (and the TH-cam community). Live long and prosper, Dr. Tyson!
Actually i think it would percieve a circle. you are thinking of it like the ant would stand in one position and look from away. from far away it would look like a line, but what if the ant moves near the circle and starts circling around ? it will definitely know that its a circle in that case. Sure the ant cant see the circle as a whole from one perspective. if you compare it to our world: can you see all the faces of a cube from one perspective? the answer is no, same for the ant, it cant see the circle as a whole. now in a 4d world, a 4D being can see the 3D cube as whole just like you can see the 2d circle as a whole... hope i explained.
@@ahmadbaydoun707 In a standard experiment the position of a singular observer, is supposed to be fixed. But even if we go with your very inquisitive, moving ant, it would still not perceive a circle. Remember, the sphere is moving. At best, it would perceive a vanishing *spiral!* Definitely, not a circle, as NDT says, *in any case.*
@@Z1BABOUINOS to understand other dimensions you need to compare them to your own dimension. 1:are you fixed in a 3d world or you are capable of moving? 2: suppose the sphere is not moving and fixed, then the ant will know it is a circle. 3: imagine a hypercube passing throught our world, at some point it stops moving, what will you see it as? as cube right? you see, just like there is no law that states that you should be fixed,there is no law that states that a 2d being must be incapable of moving. plus even if the sphere is moving, the ant has to make only one loop around the circle to realize it is a circle. after that it would know it is a circle growing and shrinking, not a spiral.
@@ahmadbaydoun707 I'm sorry but you're wrong on all counts. You change the parameters of an experiment to fit your narrative (a big no-no!) and even then you're wrong. The very concept of a sphere is incomprehensible to a 2D space inhabitant, the same way a 5 or 8D object is *visually incomprehensible* to us. Now, if you want to change *all* the parameters, including the question (what the ant comprehends, instead of what the ant sees), and you argue that your ant is the Stephen Hawking, cubed... of its universe, you might reach your conclusion.... although still, the poor ant would not be able to conclude if the object is a sphere or a striped type spiral. _ Again: The parameters *are given* in the video. The question was what AN ant *SEES,* from a *FIXED position,* when a *MOVING* sphere passes through it. The answer is *A LINE,* not a circle._

Hello! Just a few ideas about dimensions... The Star is the bridge between the dimensions of physics and chemistry. The living cell is the bridge between the dimensions of chemistry and biology. The Human is the bridge between the dimensions of biology and...? That's your dimensions right there. It's not mathematical in nature, it's rather simply a point where the sum of the parts of a certain "dimension" open up another dimension altogether. The Sun represents the harmonious interactions between Hydrogen atoms and where all other atomic elements are forged. The living cell represents the harmonious interactions between chemical components (like a controlled chemical reaction in time which can self-replicate). The laws of physics are what they are because they allow for the "world" of chemistry to exist. The laws of chemistry are what they are because they allow for the "world" of biology to exist. The laws of biology are what they are because they allow for humans (self-aware sentient creatures) to exist. The laws governing humanity will be what they will be because they will allow for ... to exist. Isn't that a good way to summarize the entire story of Humanity? Trying to uncover the laws which allow for a harmonious interaction between humans? No "4D" probing for you until you've understood and assimilated this...
I hope some day we get a detailed description of 0-dimensional space, perhaps omni-dimensional as well (if there's such a thing) in layman's terms. Unfortunately understanding that level of reality might by reserved for people as smart as NDT.
Hey Neil! As a software engineer, I understand that mathematically, we can have as many dimensions as we want. We use these dimensions (programatically) quite often... but, that's in the "mind" of the computer. If higher dimensions (beyond 4) exist in reality, how would we even go about testing for such dimensions?
"A tesseract is a small cube within a larger cube, where the inner cube is able to escape the outer cube, while still remaining attached. ... Sixteen total points, (2 cubes).. representing teleportation by exceeding the speed of light & escaping time." - Alburt Ienstiyn, 1962
what are the theoretical limitations to this 4th dimensional viewpoint? whats the difference between seeing inside me and seeing my liver to seeing inside my liver? or seeing inside the atoms that make up my liver?
Neal doesn't understand this at all... We are in the 4th dimension.. We are 4 dimensional beings. A 2 dimensional being can't perceive the second dimension. A stick figure looking at another stick figure would only see a line, the first dimension. 2 dimensional can only perceive 1 and 0 dimensions. We, as 4 dimensional beings can only perceive 3 and lower dimensions. A 2 dimensional being popping into existence would be invisible from every angle, as light cannot reflect an infinitely thin sheet of paper.
@StarTalk So when you say accessing a higher dimension to tranform medicine do you mean to say we are working on being able to do that? Or that is purely speculative?
People go back and forth on this. Most don't consider time to be a "physical place" like the 1-3 deminsions. In fact, time might always be a top level dimension. So we have 1, 2, 3 (where we are now), 4 (a new dimension we can't access) and then time on top being the 5th dimension. Its definitely confusing. Lol
@@JasonWW2000 possible. Though I would put time as the 1st, since it is required for matter as we know it to exist. Atoms needing time for electron clouds to carry a charged orbit. Supposedly at "absolute zero" it would stop in the same way, and not be able to sustain itself
I'm sorry Neil, but the "Flatlands" example of 'ants on a sheet of paper' does not work. Ants (and the thickness of the paper) have *_3 dimensions!_* BUT you _can_ *imagine* it and treat it as the abstract construct that it is. Luckily math is abstract too ~ and can be used to model these things.
The great thing is that we can imagine the transition of lower dimensions into the next. I've been thinking a lot about higher dimensions and an explanation of the 4th dimension of time and I came to the following explanation that I think will most people understand the concept better (feel free to correct me if I'm wrong, in science you have to accept If your hypothesis is wrong 😉 and if something is unclear I'm happy to answer further questions). Imagine 1 dimensional space, a line. On that line is a point which is our 1 dimensional creature and let's call the starting time time X. If the creature moves time passes but if you want to describe the position of the creature in the next moment in time you would draw another line with the position of the creature at time X+(amount of time passed). If you stack the different positions with new lines going forward in time you would stack them on top of each other in a 2nd dimension (the X axis being the dimension it could move in and the Y Axis would be the movement through time). The creature wouldn't see along the time line but it would experience the movement in the 2nd dimension as the passing of time. Same applies with 2 dimensions where the creature could move along the X and Y axis (this is actually easier to compare to a frame or a picture). This time instead of a line you would need to make a copy of a 2 dimensional space similar to the creature's "universe" and you stack the next moment on top of the previous one. This time the 'frames of time" would stack in a third dimension which the 3 dimensional creature couldn't move through (at least not the way it moves in its 2 dimensions) or see but it would experience the passage of time. So if you apply this to our 3 dimensional Space our time would move in a 4th dimension which we perceive as the passing of time. Our universe could be like a cube or a sphere and to discribe the position of us or really everything, life form, atom, particle, anything in our universe would be inside that sphere and the next moment would be the exact copy of our universe but with the positions of that moment in time and it would stack in a 4th dimension (let's call it the Z axis). Out present is Z0, our past is in the Z- direction and we move to the future in the Z+ direction. I would imagine the time between one moment to the next would be the Planck time (10 to the power of - 43 seconds if Google is right). This would also make sense with the time dilation at different speeds. If the Planck time is a fixed minimum unit an object moving faster than another would jump a bigger distance in the same amount of time. If both go in the same circle both objects would have the same distance to make a full circle. But the amount of time needed to close the circle would be less "time spheres" to the faster object than for the slow one. So at a speed high enough (close to c the speed of light) the time the object could pass through would be much less and compared to a slow moving object. Maybe we need to check if the Planck distance and time are in relation to the speed of light. I hope this makes sense and helps understand the time dimension, keep learning 😘
So would certain particles and energies that only exist (or are only perceived to exist) for only a short space of time, would these be able to be described as being of a higher dimensional object passing through our 3D plain?
As far as I understand, the fact that our sense can only deal with 3 spacial dimensions do not mean that we only exist in 3 dimensions or that we are even composed of 3 dimensions. Isn't it possible that we are, lets say, 2m in the z axis, 20 cm in the x axis, 50 cm in the y axis and 70cm in the w axis (the hypothetical 4th dimension)? There is no reason that we would no have any measure in the dimensions we can't perceive.
What if the fifth dimension is a higher dimension of time, with three dimensional space and two dimensional time. If that is a possibility we could travel along the line of time. Imagine a six dimensional world with three dimensional space and three dimensional time, you could do time travel in three axes. Your existence can be defined by three space co-ordinates and three time co-ordinates. Position,displacement,velocity,acceleration and everything becomes extremely complicated.
With the recent idea that the universe may be positively curved because of the cosmic radiation research, and the curve being considered a dimension of space beyond our 3d physical area understanding, is the universe's expansion simply the 3d observation of the positive curved sphere's expansion? Similar to drawing dots on a balloon and blowing it up?
Can a species from higher dimension show them to us in a different form which will be like a 3d to us like shapeshiting for us to not freakout and interact ..can they do that
Oh, what a joyous day, I get to correct Neil deGrasse Tyson on something. Though I am quite sure that Neil deGrasse Tyson is aware of this. An ant would not percieve a sphere descending on their plane as a dot, or a circle (that requires a view from a 3 dimensional space). The ant would se something in front of it, something that gets wider and wider before it starts to get thinner and thinner until it is gone.
Yeah. Ants, paper and desks are all horrible analogies for 2 dimensional space. Open up a 3D modeling software, create a flat plane and rotate it so it faces to the side. It disappears! It is at least a superior way of showing off 2 dimensions perceived in 3 dimensions.
@@theobserver9131 He is in the right just about always, but for once he misspoke (but that is probably to make the information easier to understand), and thus it afforded me the opportunity to correct him, even though I am quite sure he is aware of how the sphere would appear.
@@malelonewolf80 he's wrong on the sphere too.. It's only visible as a circle from above... which doesn't exist in 2 dimensional space... It would appear as a dot, then a line, growing and shrinking. 2 dimensional beings can only perceive the first and 0 dimensions. Just as us 4 dimensional beings can only perceive the third and lower dimensions..
In interesting thought about higher dimensions is that when people think about 2 dimensions, they always omit the up dimensions or the z dimensions. But is it possible for there to be two dimensions that have the xz or the yz dimensions where there exists an up/down and left/right only or a up/down and forward or backwards. What about the 4th dimension. Any 3 combination of 4 dimensions or any 2 combination of 4 dimensions. We can also do any combinations of any higher dimensions.
2:33 my issue with the EA Abbot model is that a 3D object cannot pass through a 2D plane. This was a literary device used to show how a sphere is actually a series of perfect concentric circles and would be only observable as cross-sections of cencentric circles to a 2D observer. But a 3D object cannot pass through a 2D planes; the metaphor does not actually work as described so basing our understanding of super-dimensional beings on that idea of lower-dimensional being interaction is nonsense.
how are we so sure time is a dimension, if we get past the time dimension that means there is no time on a higher dimension? how about 1 and 2 dimensions? that appears before the time dimension.
Since higher dimensional objects would look peculiar to humans, perhaps even "popping in and out of existence" as stated by Dr. Tyson, could this mean that since quantum particles do in fact appear to pop in and out of existence that matter is inter-dimensional? If so then do these higher dimensions collapse or become inhibited at the human-observable scale?
Could virtial particles be popping in and out of existence because they are in a higher dimension and occasionally just cross paths in our space-time every now and then?

Exactly.. A theoretical 2d ant can't perceive the second dimension. Only 1 and 2. Neal doesn't understand this at all.. That's why he thinks we are 3d. Obviously we are 4d, experiencing time and perceiving the third dimension.
@@Alexa-Raine Hmmm We can be in 10 Dimensional Universe but it doesn't matter because we can only access three dimensions(for now) and experience 4th as we cannot move back and forth so we are the prisoners of time.
@@Alexa-Raine About the ant analogy, 2d being can only see a dot turning to a line that increases in length ( horizontally ), and then reaching its peak and turning back into a dot and disappear. One can only see a circle if you see from above, but for ant, it will be line changing its size.
@@Shogun619 We perceive only 3 and lower dimensions, therefore we cannot perceive time of the 4th dimension, only experience it's consequences. We are necessarily made up of time, however, as we are living creatures dependant on the progression of time. Therefore we are 4 dimensional beings, only perceptive of the 3 dimensions. A stick figure, infinitely flat on a paper could not perceive a second figure stood next to it. It would only see an infinitely thin line, (assuming infinitely thin perception could detect an equally thick line). A 2 dimensional being can't perceive the second dimension, only the first(a line) and lower. The same logic holds true for us, and our perception of the 3rd dimension.
A 2D object can easily interact with a 3D object... in Neil's analogy, the ant can interact & feel it when a 3D foot steps on it. Also it will see the shadow or light cast onto it from the 3D object, like a magnified light from the sun roasting the ant.
An ant is 3 dimensional. 2 dimensional beings cannot perceive the second dimension. Only 1 and 0. Everything an infinitely thin stick figure sees would be a line or a dot. Same as us 4 dimensional beings can only perceive the 3rd dimension.
Looking at us, we in our 3 dimension world do not and have not seen or observed any living being or physical element in 2d or 1d, how can we assume a higher dimension being can observe us in our 3d dimenion world ? A higher dimension being can understand 3d concept, but cant observe our world like we do
If the 3rd dimension is depth and 2 dimensional beings can only process it one layer a time, would that not mean that the equivalent in the 4th dimension is the "now"? The only slice of time that we can process at a time. I imagine 4 dimensional beings would not necessarily see our insides but they would see our entire timeline. To them, we would be a singular event.
This is a stretch, and i am not a college educated individual, but three dimensions as i understand it only applies to things that take a shape connected at sides. Everyone says the 4th dimension is space time. So my thoughts, if the entire Earth is considered only 3 dimensions and time in space is the 4th dimension, what would gravity be? The way i see it is the 3 dimensions that we live by on earth depend on the gravity to keep us locked in the solar system and our feet on the ground. Meaning our 3 dimensional sun causes the 4th dimension of gravity. I look at time as a 5th dimension because gravity directly affects the 1, 2 and 3rd dimensions. The way i perceive it is time, in space, is the result of gravities affect. Without gravity what is time? I point this out because you cant have a 2 dimensional object without 2 lines intersecting and you need 2 seperate 2 dimensional objects to build in the 3rd dimension. We require 2 specific 3 dimensional objects (sun and earth) to live and so on. Its a play on the number 2 unintentionally thats just how it comes to mind when i analyze dimensions. Ps: are ant's not considered a 3 dimensional creature?
Love the tie and the shades . And the man wearing them oh yea and the lessons he teaches :) i think he just gave a little bit of disclosure on a favourite subject of mine lol ;)
so basically the 4th dimenson is space inside of space so even if that space is completed filled up there would still be space left, only in the 4th dimension
Is there actually any physical object in the universe that is less than three dimensions? Even a sub-atomic particle is three-dimensional, right? If there is nothing less than three dimensions, why would we think that there are things that are more?

First of all, I am a big fan of you and all you do to make people of all ages understand and love science, and, by extension, math. Thank you!
I would like to share with you an observation of how a 2-D world (ant) experiences its interaction with a 3-D world (sphere).
I am quoting you describing this interaction.
"...If we are ants on a sheet of paper living only on that 2-D, flat world, and we take a sphere and pass it through that sheet of paper, what would that look like to the ant? The ant would say, wait a minute, there is a dot, oh, the dot just became a circle..."
The way I see it, the ant, first of all, wouldn't be able to distinguish between shapes: circles, squares, etc., they would look similar since the third dimension is missing to tell where the edge is moving, for example, in a 90 degrees direction as the one of a square. Secondly, the ant would notice something appearing out of the blue coming toward it. The ant has no choice but to retreat to avoid a collision. After a while, the thing starts running away from the ant, and assuming that the 2-D ant follows it, the said something will disappear the same way it appeared in the first place. The perception of a dot, circle, square, etc. does not exist in a 2-D world, unless our 2-D ant is brought up in the third dimension and is looking down on the new, strange phenomenon (the sphere passing through the sheet of paper) to see the dot and the circle(s).
Thank you for giving me the reason to think like an ant, and share my observation with you (and the TH-cam community).
Live long and prosper, Dr. Tyson!
I had kind of the same question as Alex at 2:24
2:48 An ant in a 2D space, *would not see a circle.*
It would see a line growing in length and then shrinking to nothing.
Who's with me?
Yes! That illustration is terrible really ...showing 3D ants on a piece of paper as 2D ants ughh
Actually i think it would percieve a circle. you are thinking of it like the ant would stand in one position and look from away. from far away it would look like a line, but what if the ant moves near the circle and starts circling around ? it will definitely know that its a circle in that case. Sure the ant cant see the circle as a whole from one perspective. if you compare it to our world: can you see all the faces of a cube from one perspective? the answer is no, same for the ant, it cant see the circle as a whole. now in a 4d world, a 4D being can see the 3D cube as whole just like you can see the 2d circle as a whole... hope i explained.
@@ahmadbaydoun707 In a standard experiment the position of a singular observer, is supposed to be fixed.
But even if we go with your very inquisitive, moving ant, it would still not perceive a circle.
Remember, the sphere is moving. At best, it would perceive a vanishing *spiral!*
Definitely, not a circle, as NDT says, *in any case.*
@@Z1BABOUINOS to understand other dimensions you need to compare them to your own dimension. 1:are you fixed in a 3d world or you are capable of moving? 2: suppose the sphere is not moving and fixed, then the ant will know it is a circle. 3: imagine a hypercube passing throught our world, at some point it stops moving, what will you see it as? as cube right? you see, just like there is no law that states that you should be fixed,there is no law that states that a 2d being must be incapable of moving. plus even if the sphere is moving, the ant has to make only one loop around the circle to realize it is a circle. after that it would know it is a circle growing and shrinking, not a spiral.
@@ahmadbaydoun707 I'm sorry but you're wrong on all counts.
You change the parameters of an experiment to fit your narrative (a big no-no!) and even then you're wrong. The very concept of a sphere is incomprehensible to a 2D space inhabitant, the same way a 5 or 8D object is *visually incomprehensible* to us.
Now, if you want to change *all* the parameters, including the question (what the ant comprehends, instead of what the ant sees), and you argue that your ant is the Stephen Hawking, cubed... of its universe, you might reach your conclusion.... although still, the poor ant would not be able to conclude if the object is a sphere or a striped type spiral.
_
Again: The parameters *are given* in the video. The question was what AN ant *SEES,* from a *FIXED position,* when a *MOVING* sphere passes through it. The answer is *A LINE,* not a circle._
This week had some very interesting and thought provoking questions! Definitely saving this one to the playlist! 👍🏾👍🏾😁
@4:10 "Well, certainly that makes a certain part of my body happy"
If someone from the 5th dimension can see our insides then what can someone from the 6th see ? Or even higher ? They should see something more or less right ?
4:05 Just like when Neo healed Trinity
If you enter a concert hall first and have any choice of seating, all possibilities exist. Yet, based on an affinity towards certain qualities you tend towards a more select area. There is a non-zero chance that you will select each seat, it's just that seats in the middle of the front row tend to have a much higher probability of being chosen.
I don't like to give creadence to paranormal stuff but higher dimensional creatures popping into our dimension would explain a lot of paranormal phenomenon like the stories of Skinwalker Ranch.
I think paranormal phenomenon can also be fully explained by our brains creating these things.
@@JasonWW2000 Well, that too.
5:19 I build physical models of hypercubes.
We know what they look like.
Hello! Just a few ideas about dimensions... The Star is the bridge between the dimensions of physics and chemistry. The living cell is the bridge between the dimensions of chemistry and biology. The Human is the bridge between the dimensions of biology and...? That's your dimensions right there. It's not mathematical in nature, it's rather simply a point where the sum of the parts of a certain "dimension" open up another dimension altogether.
The Sun represents the harmonious interactions between Hydrogen atoms and where all other atomic elements are forged. The living cell represents the harmonious interactions between chemical components (like a controlled chemical reaction in time which can self-replicate). The laws of physics are what they are because they allow for the "world" of chemistry to exist. The laws of chemistry are what they are because they allow for the "world" of biology to exist. The laws of biology are what they are because they allow for humans (self-aware sentient creatures) to exist. The laws governing humanity will be what they will be because they will allow for ... to exist.
Isn't that a good way to summarize the entire story of Humanity? Trying to uncover the laws which allow for a harmonious interaction between humans?
No "4D" probing for you until you've understood and assimilated this...
I love this channel. I love neil. I love this segment. I thank this channel exists
me when a tennis ball is flying toward my face: 2:51
The best host and the guest. Period.
I hope some day we get a detailed description of 0-dimensional space, perhaps omni-dimensional as well (if there's such a thing) in layman's terms. Unfortunately understanding that level of reality might by reserved for people as smart as NDT.
Awesome show Neil! It is becoming very professional. I like the graphics as well!
These guys a brilliant
These guys are brilliant
*Thank you...* @0:23
4th dimensional beings would be crystals .... with many ways of reflecting light And refracting it !
I always come here to boggle my mind😂
Hey Neil! As a software engineer, I understand that mathematically, we can have as many dimensions as we want. We use these dimensions (programatically) quite often... but, that's in the "mind" of the computer. If higher dimensions (beyond 4) exist in reality, how would we even go about testing for such dimensions?
We need to protect Neil deGrasse Tyson at all costs!
6:01...get started...please!
"A tesseract is a small cube within a larger cube, where the inner cube is able to escape the outer cube, while still remaining attached. ... Sixteen total points, (2 cubes).. representing teleportation by exceeding the speed of light & escaping time." - Alburt Ienstiyn, 1962
what are the theoretical limitations to this 4th dimensional viewpoint? whats the difference between seeing inside me and seeing my liver to seeing inside my liver? or seeing inside the atoms that make up my liver?
Nail like a universe boss.
Neal doesn't understand this at all...
We are in the 4th dimension..
We are 4 dimensional beings.
A 2 dimensional being can't perceive the second dimension.
A stick figure looking at another stick figure would only see a line, the first dimension.
2 dimensional can only perceive 1 and 0 dimensions.
We, as 4 dimensional beings can only perceive 3 and lower dimensions.
A 2 dimensional being popping into existence would be invisible from every angle, as light cannot reflect an infinitely thin sheet of paper.
Have you seen Flatland the Movie? Because it's such a good visualisation of all the concepts you talked about here.
A good read beyond this video is Flatland by Edwin Abbott. It talks about the sphere passing through 2D and a bunch of other things.
I love these guys. Neil for president.
The is the most fun show on TH-cam
@StarTalk So when you say accessing a higher dimension to tranform medicine do you mean to say we are working on being able to do that? Or that is purely speculative?
Time is a dimension. We reside in the 4th, a higher would be the 5th
People go back and forth on this. Most don't consider time to be a "physical place" like the 1-3 deminsions. In fact, time might always be a top level dimension. So we have 1, 2, 3 (where we are now), 4 (a new dimension we can't access) and then time on top being the 5th dimension. Its definitely confusing. Lol
@@JasonWW2000 possible. Though I would put time as the 1st, since it is required for matter as we know it to exist. Atoms needing time for electron clouds to carry a charged orbit. Supposedly at "absolute zero" it would stop in the same way, and not be able to sustain itself
Gots to appreciate this channel...
Higher dimensional beings may explain paranormal activities. 😳
crazypeligro paranormal activities could be people from a higher dimension trying to communicate with our dimension 🤔
I have been to a higher dimension in the Hunter's Dream... and became a Great One.
I'm sorry Neil, but the "Flatlands" example of 'ants on a sheet of paper' does not work. Ants (and the thickness of the paper) have *_3 dimensions!_* BUT you _can_ *imagine* it and treat it as the abstract construct that it is. Luckily math is abstract too ~ and can be used to model these things.
The great thing is that we can imagine the transition of lower dimensions into the next. I've been thinking a lot about higher dimensions and an explanation of the 4th dimension of time and I came to the following explanation that I think will most people understand the concept better (feel free to correct me if I'm wrong, in science you have to accept If your hypothesis is wrong 😉 and if something is unclear I'm happy to answer further questions).
Imagine 1 dimensional space, a line. On that line is a point which is our 1 dimensional creature and let's call the starting time time X. If the creature moves time passes but if you want to describe the position of the creature in the next moment in time you would draw another line with the position of the creature at time X+(amount of time passed). If you stack the different positions with new lines going forward in time you would stack them on top of each other in a 2nd dimension (the X axis being the dimension it could move in and the Y Axis would be the movement through time). The creature wouldn't see along the time line but it would experience the movement in the 2nd dimension as the passing of time.
Same applies with 2 dimensions where the creature could move along the X and Y axis (this is actually easier to compare to a frame or a picture). This time instead of a line you would need to make a copy of a 2 dimensional space similar to the creature's "universe" and you stack the next moment on top of the previous one. This time the 'frames of time" would stack in a third dimension which the 3 dimensional creature couldn't move through (at least not the way it moves in its 2 dimensions) or see but it would experience the passage of time.
So if you apply this to our 3 dimensional Space our time would move in a 4th dimension which we perceive as the passing of time. Our universe could be like a cube or a sphere and to discribe the position of us or really everything, life form, atom, particle, anything in our universe would be inside that sphere and the next moment would be the exact copy of our universe but with the positions of that moment in time and it would stack in a 4th dimension (let's call it the Z axis). Out present is Z0, our past is in the Z- direction and we move to the future in the Z+ direction.
I would imagine the time between one moment to the next would be the Planck time (10 to the power of - 43 seconds if Google is right). This would also make sense with the time dilation at different speeds. If the Planck time is a fixed minimum unit an object moving faster than another would jump a bigger distance in the same amount of time. If both go in the same circle both objects would have the same distance to make a full circle. But the amount of time needed to close the circle would be less "time spheres" to the faster object than for the slow one. So at a speed high enough (close to c the speed of light) the time the object could pass through would be much less and compared to a slow moving object.
Maybe we need to check if the Planck distance and time are in relation to the speed of light.
I hope this makes sense and helps understand the time dimension, keep learning 😘
So would certain particles and energies that only exist (or are only perceived to exist) for only a short space of time, would these be able to be described as being of a higher dimensional object passing through our 3D plain?
Such as Dark Energy, Dark Matter, Gluons etc.?
As far as I understand, the fact that our sense can only deal with 3 spacial dimensions do not mean that we only exist in 3 dimensions or that we are even composed of 3 dimensions.
Isn't it possible that we are, lets say, 2m in the z axis, 20 cm in the x axis, 50 cm in the y axis and 70cm in the w axis (the hypothetical 4th dimension)?
There is no reason that we would no have any measure in the dimensions we can't perceive.
It's a possibility like anything else we do not yet know.
Chuck is the best but Neil is also the best
What if the fifth dimension is a higher dimension of time, with three dimensional space and two dimensional time. If that is a possibility we could travel along the line of time.
Imagine a six dimensional world with three dimensional space and three dimensional time, you could do time travel in three axes. Your existence can be defined by three space co-ordinates and three time co-ordinates. Position,displacement,velocity,acceleration and everything becomes extremely complicated.
With the recent idea that the universe may be positively curved because of the cosmic radiation research, and the curve being considered a dimension of space beyond our 3d physical area understanding, is the universe's expansion simply the 3d observation of the positive curved sphere's expansion? Similar to drawing dots on a balloon and blowing it up?
3:25 ghosts. Freaking ghosts.
Thank you I had missed it
We need an episode with Chuck and Paul mecurio
What would a 4d grid look like from our 3d world?
The idea of us being shadows of higher dimensional beings absolutely terrifies me
Relax! When the light comes, the fear goes away!
Can a species from higher dimension show them to us in a different form which will be like a 3d to us like shapeshiting for us to not freakout and interact ..can they do that
Neil awesome man learning every watched almost every star talk episode. Thanks for all the information we never got in school
"Know thou that the Kingdom is the real world, and this nether place is only it's shadow stretching out" 'Abdu'l-Baha
Oh, what a joyous day, I get to correct Neil deGrasse Tyson on something. Though I am quite sure that Neil deGrasse Tyson is aware of this. An ant would not percieve a sphere descending on their plane as a dot, or a circle (that requires a view from a 3 dimensional space). The ant would se something in front of it, something that gets wider and wider before it starts to get thinner and thinner until it is gone.
Yeah. Ants, paper and desks are all horrible analogies for 2 dimensional space. Open up a 3D modeling software, create a flat plane and rotate it so it faces to the side. It disappears! It is at least a superior way of showing off 2 dimensions perceived in 3 dimensions.
Thank you! Neil is acting as a science mis-educator.
@@theobserver9131 He is in the right just about always, but for once he misspoke (but that is probably to make the information easier to understand), and thus it afforded me the opportunity to correct him, even though I am quite sure he is aware of how the sphere would appear.
@@malelonewolf80 After listening again, I have to agree.
@@malelonewolf80 he's wrong on the sphere too..
It's only visible as a circle from above... which doesn't exist in 2 dimensional space...
It would appear as a dot, then a line, growing and shrinking.
2 dimensional beings can only perceive the first and 0 dimensions.
Just as us 4 dimensional beings can only perceive the third and lower dimensions..
Back in the 70s I thought I was in the fifth dimension. Then I realized I was an aquarius so I let the sunshine in.
@StarTalk
Could you bring an episode about the whole longevity research scene around Dr. David Sinclair and what that could mean for space travel?
In the 4d world surfaces are volumes. Lines are surfaces. Points are lines. The point in 4d can not defined in 3d.
Did anyone notice Neil rocking a Van Gogh tie??
I’m always coming to these videos like a crackhead for a hit of science
In interesting thought about higher dimensions is that when people think about 2 dimensions, they always omit the up dimensions or the z dimensions.
But is it possible for there to be two dimensions that have the xz or the yz dimensions where there exists an up/down and left/right only or a up/down and forward or backwards.
What about the 4th dimension. Any 3 combination of 4 dimensions or any 2 combination of 4 dimensions.
We can also do any combinations of any higher dimensions.
The real answer to many of these questions is - "We don't know" . Drill down past all the verbiage and that's what is left .
I love the fact I could interact with you guys, I guess this is a new way of learning.
"Learning"
I m a simple guy. I see complex thumbnails. I watch them
Thank u sir for this video
2:33 my issue with the EA Abbot model is that a 3D object cannot pass through a 2D plane.
This was a literary device used to show how a sphere is actually a series of perfect concentric circles and would be only observable as cross-sections of cencentric circles to a 2D observer.
But a 3D object cannot pass through a 2D planes; the metaphor does not actually work as described so basing our understanding of super-dimensional beings on that idea of lower-dimensional being interaction is nonsense.
how are we so sure time is a dimension, if we get past the time dimension that means there is no time on a higher dimension? how about 1 and 2 dimensions? that appears before the time dimension.
Genius... I'm impressed
also. i feel for you chuck i really do.
Since higher dimensional objects would look peculiar to humans, perhaps even "popping in and out of existence" as stated by Dr. Tyson, could this mean that since quantum particles do in fact appear to pop in and out of existence that matter is inter-dimensional? If so then do these higher dimensions collapse or become inhibited at the human-observable scale?
Could virtial particles be popping in and out of existence because they are in a higher dimension and occasionally just cross paths in our space-time every now and then?
I’m dimensionally handicapped. I’m missing my left dimension
Wtf
Incorruptus I appreciate the support brother. Let’s get that Crowd Fund going for me! Lol
Incorruptus Although I appreciate your tenacity, I’m afraid pocket change won’t be enough. I’m severely dimensionless and will require at least billions of dollars.
Correction : it would be a line not a circle for an ant.
Exactly..
A theoretical 2d ant can't perceive the second dimension. Only 1 and 2.
Neal doesn't understand this at all..
That's why he thinks we are 3d.
Obviously we are 4d, experiencing time and perceiving the third dimension.
@@Alexa-Raine Hmmm
We can be in 10 Dimensional Universe but it doesn't matter because we can only access three dimensions(for now) and experience 4th as we cannot move back and forth so we are the prisoners of time.
@@Alexa-Raine About the ant analogy, 2d being can only see a dot turning to a line that increases in length ( horizontally ), and then reaching its peak and turning back into a dot and disappear.
One can only see a circle if you see from above, but for ant, it will be line changing its size.
@@Shogun619 precisely and well put.
Neal, though perhaps for the audience, is very wrong in his analogies this time.
@@Shogun619 We perceive only 3 and lower dimensions, therefore we cannot perceive time of the 4th dimension, only experience it's consequences.
We are necessarily made up of time, however, as we are living creatures dependant on the progression of time.
Therefore we are 4 dimensional beings, only perceptive of the 3 dimensions.
A stick figure, infinitely flat on a paper could not perceive a second figure stood next to it. It would only see an infinitely thin line, (assuming infinitely thin perception could detect an equally thick line).
A 2 dimensional being can't perceive the second dimension, only the first(a line) and lower.
The same logic holds true for us, and our perception of the 3rd dimension.
A 2D object can easily interact with a 3D object... in Neil's analogy, the ant can interact & feel it when a 3D foot steps on it. Also it will see the shadow or light cast onto it from the 3D object, like a magnified light from the sun roasting the ant.
An ant is 3 dimensional.
2 dimensional beings cannot perceive the second dimension.
Only 1 and 0.
Everything an infinitely thin stick figure sees would be a line or a dot.
Same as us 4 dimensional beings can only perceive the 3rd dimension.
Looking at us, we in our 3 dimension world do not and have not seen or observed any living being or physical element in 2d or 1d, how can we assume a higher dimension being can observe us in our 3d dimenion world ? A higher dimension being can understand 3d concept, but cant observe our world like we do
If the 3rd dimension is depth and 2 dimensional beings can only process it one layer a time, would that not mean that the equivalent in the 4th dimension is the "now"? The only slice of time that we can process at a time. I imagine 4 dimensional beings would not necessarily see our insides but they would see our entire timeline. To them, we would be a singular event.
I just stumbled upon this video and don't know why but that shirt and tie just reminded me of Larry King
So why does the the forth dimention involves time? Is time a dimention ?
Chuck nice jacket is clean af.
This is a stretch, and i am not a college educated individual, but three dimensions as i understand it only applies to things that take a shape connected at sides. Everyone says the 4th dimension is space time.
So my thoughts, if the entire Earth is considered only 3 dimensions and time in space is the 4th dimension, what would gravity be? The way i see it is the 3 dimensions that we live by on earth depend on the gravity to keep us locked in the solar system and our feet on the ground.
Meaning our 3 dimensional sun causes the 4th dimension of gravity. I look at time as a 5th dimension because gravity directly affects the 1, 2 and 3rd dimensions. The way i perceive it is time, in space, is the result of gravities affect. Without gravity what is time?
I point this out because you cant have a 2 dimensional object without 2 lines intersecting and you need 2 seperate 2 dimensional objects to build in the 3rd dimension. We require 2 specific 3 dimensional objects (sun and earth) to live and so on. Its a play on the number 2 unintentionally thats just how it comes to mind when i analyze dimensions.
Ps: are ant's not considered a 3 dimensional creature?
Try Wassily Kandinsky Point and Line to Plane 1926.
Love the tie and the shades . And the man wearing them oh yea and the lessons he teaches :) i think he just gave a little bit of disclosure on a favourite subject of mine lol ;)
Neil deGrasse Tyson: Don't get me started. 🥰😂😂
This is the first time I have seen 0 dislike in a video with more than 800 views.
so basically the 4th dimenson is space inside of space
so even if that space is completed filled up there would still be space left, only in the 4th dimension
Is there actually any physical object in the universe that is less than three dimensions? Even a sub-atomic particle is three-dimensional, right? If there is nothing less than three dimensions, why would we think that there are things that are more?
