In theoretical physics and mathematics, the concept of five dimensions can be real in specific contexts, such as string theory, which posits additional dimensions beyond the familiar four (three spatial and one temporal). These higher dimensions are not directly observable but can have implications for the fundamental nature of the universe. In mathematics, five-dimensional spaces are well-defined and can be studied abstractly, but they do not correspond to physical reality as we experience it in everyday life. Thus, while five dimensions are real in certain theoretical frameworks, they are not part of our direct physical experience.

Two dimensional is flat like a square and circle. Three dimensional is real life like, like a sphere and cube.
In a real star, no. In a 2-dimensional star-shape, no. In 3-dimensional star-shapes, yes, there can be.
It is a picture of a fire. Real fires are 3D.

3-dimensional, if it's in real life. If it's merely a picture, then it's a 2-dimensional object depicting something that's 3-dimensional.

Two dimensional is flat like a square and circle. Three dimensional is real life like, like a sphere and cube.
A 5-sided 2-dimensional figure is a pentagon and a 5-sided 3-dimensional shape is a pentahedron.
3D stands for 3 dimensional. If something is 3 dimensional it appears to you as if it were real and lifelike.
A photograph is a two dimensional representation of a real-life scene. A hologram is three a dimensional representation.
Electrons, like all physical objects in the real world, are 3 dimensional (or 4 dimensional if you include time, as Einstein does). Two dimensional objects with zero thickness exist only as mathematical abstractions.
In a real star, no. In a 2-dimensional star-shape, no. In 3-dimensional star-shapes, yes, there can be.

The model is similar to the real object because of how it is three-dimensional.
