In physics there is something called the 4 Vector which describes space-time it can be described by the matrix[x y z ict]where i is the square root of negative 1 and c is the speed of light in a perfect vacuum and t is time. This describes the 4-dimensional reality we live in.
And for those of you who don`t believe time is a dimension, research Special Relativity. It`s been scientifically proven to be accurate, and relies on time being considered as another dimension, albeit one which we have no control of.
he said anal xD
time is a measurement
just like inches or centimeters
Me too. This used to make sence to me before, but now this video had completely trashed what I used to think I understood.
I`m going back to bed.
I think that dimension 1 is just a line- if you work backwards from their definition of dimension 3= an infinite number of planes laid on top of each other, then 2-d must be an infinite number of lines laid side-by-side.Maybe?I don`t think that ideas have duration. How can you mark when an idea starts? And if you believe that there is no original thought, then all ideas have existed since the beginning of time, and they will end at the end of time. And Time as the 4th dimension is not really what the video is talking about- it fits well, but this is one of the best *mathematical* models for a possible fourth dimension.Of course, my brain is laying in pieces, exploded on the floor, so... nothing makes sense anymore.
I think I get the drawing bit, and infact if a 4d person draws in 3d it can make objects that we can interract with?
We (being 3 dimensional objects) can only percieve one point in time at any given moment.
It just gets kind of weird when you think about drawing in time.
Time is not an illusion.
(1) Duration; (2) Length; (3) Width; (4) Height
This is why time travel will always be impossible - you can only travel in 4D space; you can`t, for example, travel along a line which has only duration and length, but width and height are 0.
Sorry, but I disagree strongly. Please define time and you will find it`s pretty much impossible. We think of things in causal ways, but this is not indicative of any order, or of time. Before us, there was no time. No one to think of it. Because, there is no time. It`s just an illusion.
I could see myself from the corner of the room, yet I was sitting down in the opposite corner, all in real live time!
I AM MUTANT WITH A 4TH DIMENSIONAL SIGHT!!!! WOOHOOO!!
Despite this, however, my head is still hurting from trying to understand this one.
Simply put, a processor`s computation power is not linked to the data stream running into it. It is intrinsic; likewise, humans have the capability of thinking and analyzing in three dimensions, even though they can only technically percieve visually in two of them.
And P.S., for those of you looking for a `testable hypothesis`...are you serious? This is clearly a theory, and is stated as such. NOT as fact. Once we are able to test and even prove the existence of a higher dimension, we (and listen carefully here) have the technology to prove/disprove GOD.
And, perhaps more interestingly, INTERACT with God.
I disagree. Imagine you (as a 3D being) were able to view a VERY LARGE 2D plane - say... the size of the field in a large stadium. Many many many small 2D beings (say, ants... though not technically 2D, this will suffice) are walking on/in this 2D surface. Just because you were able to interact in a higher dimensional space doesn`t mean you`re omniscient. It just means you have a different perspective. In this example, you may be able to see the ants from "above" - implying that you may even be able to see more ants than if you were 2D. But this would be far from omniscience.
1D- no two things can occupy the same point on a length
2D- two things can occucupy the same point on a length, just not on the same width
3D- two things can occupy the same length and width, just not the same height
4D- two things can occupy the same length width and height, just not at the same time
Visualizations such as the one in this video are difficult IMO. This one does a decent job but I think the creators went to far in the inferences. They should have just stuck to explaining higher-dimensional space and left any implications out.
See Plato`s Allegory of the Cave for an introduction.
Perhaps, but not likely. You`d have to impose additional assumptions on this framework - perhaps including a connection between a 4th (or higher) dimension, and death.
A better way to say it MIGHT be to state that "IF ghosts are 3D cross-sections of 4D beings, that would not be inconsistent with ghosts being able to appear and disappear at will - because they would simply be traveling within the 4D space and outside our field of view."
I would do anything to know the answers to these questions....
::stares into space::
Height, width, and depth are dimensions, remember. An easy way to look at it is that difference between 2D and 3D is the addition of depth to the picture. You couldn`t have an object with only height and depth -- it`s progressive.
Man, this stuff is instant mind orgasms.
I`ve always found this subject absolutely fascinating.
Video is too looong.....So I did not watch it all. Plus, the Mac Speech function thing gets old-FAST.
We can`t see them because they`re in the 4th dimension.......but they can see us.
I have no trouble thinking in 3D. This whole thing was like a poor re-hash of "flatland" by someone who didn`t understand it very well.
well.. thats impossible as we are 3d. the same as a 4d lifeform would find it hard to imagine the perspective of a 5d lifeform
Why couldn`t they just have a regular person narrate the video? Surely easier than the fake voice thing.
On a side note the pop-ups are horrible i-a-b. Don`t you love us anymore? If I didn`t have the wonderful AdBlocker on Firefox I would be seriously annoyed.
I love i-a-b, the site kicks ass but don`t ruin it with pop-ups that just sucks...
also because I`ve seen vids like this before and the narrators` voices were not nearly as annoying.
I`m actually quite up on string theory and have been reading about it for the past ten years or so now.
I like "Imagining the 10th Dimension" better anyways.http://www.youtube.com/watch?v=JkxieS-6W...
Agreed. I could only watch so much before it started to agitate me. I noticed the anonymous symbol, they`re still around- Eh?
And Sean162, the world ISNT going to end in 2012. Cripe.
*this lecture brought to you by Scientific American and too much time on my hands*
*oh yeah also my massive BRAAAAAINS*
Time is not a spacial dimension. If there is a fifth spacial dimension, a fourth spacial dimension is also necessary.
Idiots. Everyone knows that time is the fourth dimension. Now the fifth dimension...
