Microdimensional

Microdimensional mastery was proposed by John Barrow, going by the fact that humans (or other civilizations) have found it more cost-effective to extend any abilities to manipulate their environment over increasingly smaller dimensions rather than increasingly larger ones, therefore reversing the classification downward from Type I-minus to Type Omega-minus.

Microdimensional categories of the Kardashev scale:

Microdimensional	Corresponding	Description
Type I-minus	K0.3	capable of manipulating objects over the scale of themselves: building structures, mining, joining and breaking solids
Type II-minus	K0.7	capable of manipulating genes and altering the development of living things, transplanting or replacing parts of themselves, reading and engineering their genetic code
Type III-minus	K0.7	capable of manipulating molecules and molecular bonds, creating new materials
Type IV-minus	K0.9 to K1	capable of manipulating individual atoms, creating nanotechnologies on the atomic scale and creating complex forms of artificial life
Type V-minus	K1 to K2	capable of manipulating the atomic nucleus and engineering the nucleons that compose it
Type VI-minus	K3	capable of manipulating the most elementary particles of matter (quarks and leptons) to create organized complexity among populations of elementary particles
Type Omega-minus	K4	capable of manipulating the basic structure of spacetime and the fabric of reality

According to this scale, humans, having wide expertise in various branches of chemistry and biology, have passed the stage of Type III-minus. Type IV-minus technologies (that have had practical and widespread applications) have been seen in areas like nanotechnology, semiconductors, materials science and genetic engineering, whereas Type V-minus has seen large scale application in the field and subfields of nuclear physics. Type VI-minus has had tentative research in the field of particle physics with particle colliders such as the Large Hadron Collider.
