Kardashev Type 4.0 Universal Civilizations

A civilization that has transcended its galaxy and harnesses the energy of the entire visible universe. This implies mastery over cosmology itself—the ability to manipulate dark energy, harness the radiation of the cosmic microwave background, and perhaps even control the expansion rate of the universe within their domain. Their projects span billions of light-years and billions of years.

Kardashev Type 4.0 Universal Civilizations *Example: The Q Continuum from Star Trek, beings that exist outside of time and play with cosmic forces, or the Time Lords from Doctor Who at the height of their power, approach this level. A Type 4.0 civilization might be responsible for the apparent fine-tuning of physical constants, or be fighting a war using galactic clusters as ammunition.*
