The concept of negative dimensions in the context of quantum theory is not a well-established or widely accepted idea within the scientific community. In standard physics and mathematics, dimensions are generally understood as positive integer values that describe the number of independent coordinates needed to specify a point in a space.
Quantum theory itself does not directly propose the existence of negative dimensions. Instead, it provides a mathematical framework to describe the behavior of particles and fields on various scales, including the microscopic realm. Quantum mechanics is primarily concerned with the probabilistic nature of particles and their interactions, rather than the geometric properties of space.
While there have been various speculative theories and ideas proposed in theoretical physics that go beyond the traditional understanding of space and dimensions, such as string theory and higher-dimensional models, the concept of negative dimensions has not been supported by empirical evidence or widely accepted within the scientific community.
It's important to note that theoretical ideas and speculations should be subject to rigorous testing and verification through experimental observations or compelling mathematical evidence before they can be considered as part of the established scientific understanding. there is no experimental or observational evidence supporting the existence of negative dimensions.
