It is found that in d= 11 simple supergravity, with a minisuperspace ansatz, all instantons must have a four dimensional sector. It suggests that this is the main reason why space-time is four-dimensional.doi:10.1007/BF00773627Wu Zhong Chao...
What is the dimensional formula of stress? Which seems more plausible: a. All matter in the universe, which cannot occupy the same space at the same time according to physics, all emerging from a singularity, i.e. the same place, at a single instant, i.e. the same time, and eventuall...
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 dimensionsby squishing it down to three. Plotting four dimensions in the xyzw coord...
In mathematics, space is defined as a boundless, three-dimensional continuum where objects can have relative positions, directions and size. The dimensions are generals associated with the X, Y and Z axes. In some cases, the three dimensions of space are combined with the dimension of time, c...

Within the bulk, as the theory goes, exists our four-dimensional universe (three physical dimensions, plus time), sitting on a membrane ("brane") within the bulk's higher-dimensional space. The number of dimensions in the bulk varies depending on the model — some say five, others seven,...
special effects in films and 3D video games. It enables designers to add layers of pixels with depth qualities, also known as textures, which make 3D images look more realistic. CGI also uses ray tracing, which re-creates how light interacts with solid objects in three-dimensional space. ...

This was one has puzzled the human innumerable era question.In our majority of person's cognition, the universe is the three-dimensional space.We can through the three dimensional coordinates determination space random position.We are right?

The state space of a given system type is represented by a convex set living inside some real vector space. For instance, an atomic quantum system \({{{\mathcal{Q}}}_{2}\) has states living inside a Bloch sphere in a 4-dimensional real vector space, an atomic classical state \({{...
