You mentioned Michio Kaku

shunwah has left a new comment on your post "腦控電腦 by a.s.":

You mentioned Michio Kaku's Future of Civilization. I had read about this theory in Astronomy 2002 Februray.
But the idea was from Nikolai Kardasev published in the Journal of Soviet Astronomy in1964.

I want to know when you got this?
Who are you?
