What is exactly mean 4D? i heard that there is 11D how can that be possible?

Question

please do tell me about dimensional theory and who proposed it.

Answer 1

This is a very difficult concept and you probably won't get a great answer for it. First off, this is only speculation - there is not a shred of evidence that there are 11 physical dimensions. We can only claim 3 (time is considered the 4th dimension, because you need all 4 to describe to fully describe an event - for example, if you throw a rock in the air, if you want to know everything about where it lands you have to know the longitude, latitude, altitude and time with regards to a reference point).

11 physical dimensions spring from string theory, which postulates that everything including time and space and matter and force are made up of vibrating "strings", either open ended or looped like rubber bands. These strings are inconceivably tiny - if an electron were the size of the solar system out to Jupiter's orbit, filling in the volume, the string would be about the size of a granny apple. It's thought that physical dimension 4-11 curled in on themselves at the Big Bang, and are only relevant on the same scales as the strings themselves - the other 3 expanded to fill the universe that we know today.

One way to image it is to imagine the Earth as a perfect sphere, without mountains or valleys, no hills, no riverbanks, no sidewalks, just a perfect, absolutely perfect sphere. Now imagine an ant walking on the sphere. The Earth is so fricken huge compared to the ant that the ant will only think there are two dimensions, x and y (assume that the ant has no self-awareness, and didn't realize he himself is above the x-y plane). In reality, the Earth is a sphere, with a z component, but the ant will never know that. The same, in reverse, could be true for the other 7 dimensions - they are so small we can never comprehend them.

Unfortunately, with today's physics, that also means we can never confirm or deny their existence. Without empirical proof, string theory is just beautiful mathematics, without a shred of proof.

Answer 2

Think of an empty cardboard box. It has 3 physical dimensions -- length, width and depth. That's 3D. There's also one more dimension associated with those three -- time. This is so because it takes time to move from one place to another in the 3D world.

The 11 dimensions you asked about are purely theoretical and so far have not been confirmed as actually existing. Eleven dimensions are required to make some of the math equations associated with a theory called "string theory" to come out correctly.

Answer 3

Hi, interesting question because I am researching about this number 11 and the 11th dimension fits into growth and decay as far as I can see.
I do actually see the superstring theory fitting into this too
Although all the dimensions will have relevance to each other=width depth and length, time is square making all dimensions equivalent yet all will hold a unique purpose too, like the third dimension is associated with electromagnetism the 11th is growth and decay-

my opinion

Answer 4

in basic terms went to a theater on the national aquarium the place there's a 4D action picture. replaced into questioning an identical element what's 4D? It seems that 4D is 3-D plus you get to sense specific issues interior the action picture. while a guy spits there is water that shoots up at your face, while it snows there are flakes that fall interior the theater, your seat strikes or shakes, and there are a number of different issues that ensue to incorporate your experience of touch.

Answer 5

There is no 11D so far. However, 4D is true. Game like WoW is a example of 4D game.

Answer 6

4D is 4-Dimensional
The Dimensions of Space, Mass, Time and Weight
are equivalent to Length, Breadth, Height and Width
4D is more advanced than 3D and also has provision to include the 4th dimension of Time in Quantum Physics

Answer 7

That was me. I was nominated for the Nobel Prize for Physics in 1987 for my proposal.

I am very proud. My dog, Fred J. Muggs, was the first to propose the theoretical structures...I simply ironed out the fine details.

We are the Batman and Robin of theoretical physics.

Answer 8

Hi, if you are referring to 4D movies, it is revolutionary technology in digital cinema.
in 3D movies we feel the length, breadth and depth in the movie, whereas in 4D movies, you will feel the senses (as 4th dimension). that means, if cool breeze blows in the movie, you feel the chillness, if any insect crawling in the movie, you will the crawling sense on your feet, if it rains in the movie, you will get wet (lightly) in your seat. it's amazing, isn't it?

Answer 9

Lord Voldemort will use the curse.
Potter be aware

Answer 10

i dont know either, sounds fascinating though
