Greetings,
Indeed, the time distorsion is not linear. I was just simplifying too much.
Concerning other comments:
"Sounds to me like the kind of twaddle a scifi writer would come out with- Asimov or Clarke from the sound of it. "
Nope, it came from a very serious scientific community. First time I read about it, it was in Discovery magazine then I made some more researches on the web. It is a simple classification. There are others, but this one is the most known and it is done in relation with energy consumption. I am not a physicist or futurologist. Just a simple engineer. hehe
"Why would you *want* to harness all the energy of a galaxy, or a solar system, or a planet? If we could harness all of Earth's energy, we would have thousands of times more energy than we had any clue what to do with."
Not really. Our knowledge of the universe and fundamental physic is far beyond our technological knowledge. Only the energy of the earth will be far from suficient in a distant futur. I gave as an example the Star Trek Enterprise. In theory, a ship like that one would deplete the earth energy in a very few time.
I am not offensed at all. Just that I can't put here the whole "Energy classification" thing. It was more to point out to some people to fin some reading. I underestimated the people by simplifying too much. Anyway, next time I'll have more scientific rigor.
Thank you
