Is there any experimental evidence that confirms or points toward extra spatial dimensions? I have been looking around for a bit, couldn't find anything.
Thomas Larsson said:If extra spatial dimensions exist, they must be smaller than 45 um.
mjsd said:This is if you assume that extra-dimensions are compactified and that gravity is not confined. In the warped spacetime of Randall and Sundrum, you can have "large extra-dimensions" without violating Newton's law.
see for example: Phys.Rev.Lett. 83 (1999) 4690-4693 [hep-th/9906064]

Extraspatial dimensions are hypothetical dimensions beyond the three dimensions of space and one dimension of time that we experience in our daily lives. These dimensions are often described as curled up or compactified, meaning they are too small for us to perceive directly.
Scientists gather experimental evidence for extraspatial dimensions through various methods, including particle accelerators, gravitational wave detectors, and astronomical observations. These experiments look for deviations from the expected behavior of particles and forces, which could indicate the presence of additional dimensions.
One example of experimental evidence for extraspatial dimensions is the work done at the Large Hadron Collider (LHC) in Switzerland. The LHC has been searching for evidence of supersymmetry, a theory that predicts the existence of additional dimensions. Although no conclusive evidence has been found yet, the LHC has ruled out certain possibilities and continues to search for signs of extra dimensions.
Extraspatial dimensions play a crucial role in theories like string theory and M-theory, which attempt to unify all the known forces and particles in the universe. These theories propose that the fundamental building blocks of the universe are not particles, but tiny strings vibrating in multiple dimensions. The number and nature of these dimensions are key components of these theories.
While the study of extraspatial dimensions is still in its early stages, there are potential practical applications for this research. For example, understanding the properties and behavior of extra dimensions could lead to breakthroughs in technology, such as improved energy sources and advanced materials. Additionally, a deeper understanding of the fundamental nature of the universe could have implications for our understanding of reality and our place in the cosmos.
