An Extended Kardashev Scale

Understandably, it’s not very detailed. But here we go:

A type 3 civilization is of another order of evolution altogether, probably taking 100,000 years or longer to get there. Kardashev saw it as “a civilization in possession of energy on the scale of its own galaxy”. […] … What’s next after such an advancement? Kardashev didn’t see a need to hypothesize any further civilizations, but prognosticators since then have proposed that a type 4 world would be able to harness the energy of an entire universe, while a type 5 can do the same in a multiverse, drawing power from multiple universes. […] What about type 6? We are talking god stuff here, controlling time and space, creating universes at will. Type 7? We can’t even imagine and understand what that could be like. …

(It’s hard to be confident about why Type 7 needed tacking on.)
