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:
|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.
