there is no scientific evidence or theory that suggests matter can be collapsed into two dimensions or fractional dimensions like 2.5 dimensions. The dimensions we commonly perceive in our everyday life are the three spatial dimensions: length, width, and height.
In physics, the concept of dimensions goes beyond our intuitive understanding. In string theory, which is a theoretical framework aiming to unify quantum mechanics and general relativity, it is postulated that there may be more than three spatial dimensions. However, these extra dimensions are considered to be compactified or "curled up" at scales far smaller than what we can currently observe or interact with.
The idea of solid state teleportation, where an object is instantaneously transported from one place to another, is still purely speculative and falls outside the realm of our current scientific understanding. While teleportation of quantum states has been achieved in experiments using quantum entanglement, it involves the transfer of information rather than physically moving objects through space.
It's important to distinguish between scientific concepts and the portrayal of dimensions or teleportation in popular culture, such as science fiction. While such ideas can be entertaining and thought-provoking, they often exceed the limits of our current scientific knowledge and understanding.
As scientific research and exploration continue to advance, our understanding of the universe may evolve, and new theories may emerge. However, as of now, there is no scientific basis to support the collapse of matter into two dimensions or the possibility of solid state teleportation as commonly depicted in fictional works.
