According to Einstein , you need to describe where you are not only in three-dimensional space — length, width and height — but also in time. Time is the fourth dimension. So to know where you are, you have to know what time it is.
Scientists have confirmed the existence of a fourth dimension that Albert Einstein once predicted but could never prove.
In 1880 Charles Howard Hinton popularized it in an essay, "What is the Fourth Dimension?", in which he explained the concept of a "four-dimensional cube" with a step-by-step generalization of the properties of lines, squares, and cubes.
In 1905, Albert Einstein showed in his Special Theory of Relativity that space is intimately connected to time via the cosmic speed limit of light and so, strictly speaking, we live in a Universe with four dimensions of space-time.
Generally speaking, when we talk about a fourth dimension, it's considered space-time.
Theoretical physicists believe math shows the possibilities of a fourth dimension, but there's no actual evidence—yet. Albert Einstein believed space and time made up a fourth dimension. An example from a string theorist gives a view of what a fourth dimension could be.
Thankfully, there are no 4D creatures inhabiting our Universe, as they would appear indistinguishable from physics-defying, godlike entities. But what if instead of us being higher-dimensional creatures in our Universe, the Universe itself had more dimensions that it has right now?
In physics, information has sometimes been proposed as the fifth dimension, the first three being the three axes of space, and the fourth being time. This is because information influences and shapes the physical reality of the universe similar to space and time.
The 5th dimension is a conceptual, unobservable microdimension of space. It's considered a spatial dimension, like the 3D length, height, and depth we're familiar with. In theory, it's a plane of spacetime that's curved in on itself so tightly, the entire dimension is a loop smaller than an atom.
Albert Einstein accepted the modern cosmological view that the universe is expanding long after many of his contemporaries. Until 1931, physicist Albert Einstein believed that the universe was static.
The 3D volumetric structure or form of human facial features contains spatial dimensions of breadth, height and width, combined with a unique surface pattern. The 4D temporal pattern of the human face encompasses all dynamic movement and changes to this 3D spatial form that evolve with time.
The Bible also contains examples of appearances which also are easily explained with the use of the Fourth Dimension. Twice, Jesus entered the room of the disciples without using a door (John 20:19-23, 26-29). Entering a room through its walls is only possible via the Fourth Dimension.
According to Einstein , you need to describe where you are not only in three-dimensional space — length, width and height — but also in time. Time is the fourth dimension. So to know where you are, you have to know what time it is.
Finding it too formal, Einstein believed that Heisenberg's matrix mechanics was incorrect. He changed his mind when Schrödinger and others demonstrated that the formulation in terms of the Schrödinger equation, based on wave–particle duality was equivalent to Heisenberg's matrices.
Our brains are not hardwired to picture anything beyond 3 dimensions. Life on Earth only goes until the 3rd dimension. The human brain cannot imagine something that it has never been exposed to (such as the 4th dimension).
A polytope in seven dimensions is called a 7-polytope. The most studied are the regular polytopes, of which there are only three in seven dimensions: the 7-simplex, 7-cube, and 7-orthoplex.
Six-dimensional space is any space that has six dimensions, six degrees of freedom, and that needs six pieces of data, or coordinates, to specify a location in this space. There are an infinite number of these, but those of most interest are simpler ones that model some aspect of the environment.
What is 11th dimension? The 11th dimension is a characteristic of space-time that has been proposed as a possible answer to questions that arise in superstring theory. The theory of superstrings involves the existence of nine dimensions of space and one dimension of time for a total of 10 dimensions.
The Sixth Dimension is the final realm and highest plane of existence in the Multiverse whose inhabitants exist beyond time and are capable of things beyond the imagination of most living beings.
As of now, we can't see the fifth dimension, but rather, it interacts on a higher plane than we do. It's because of this that we can't really study nor fully prove it's existence.
In the tenth and final dimension, we arrive at the point in which everything possible and imaginable is covered. Beyond this, nothing can be imagined by us lowly mortals, which makes it the natural limitation of what we can conceive in terms of dimensions.
A 4-D being would be a god to us. It would see everything in our world. It could even look inside your stomach and remove your breakfast without cutting through your skin, just like you could remove a dot inside a circle by moving it up into the third dimension, perpendicular to the circle, without breaking the circle.
Likewise, we can describe a point in 4-dimensional space with four numbers – x, y, z, and w – where the purple w-axis is at a right angle to the other regions; in other words, we can visualize 4 dimensions by squishing it down to three. Plotting four dimensions in the xyzw coordinate system.
Needless to say, humans cannot touch objects defined in 4D space, since their bodies are situated in 3D space. The tactile sensations are the information mapped onto their skin, which is arranged in 2D surface.
