By definition, an advanced civilisation must grow faster than the frequency of life-threatening catastrophes. Since large meteor and comet impacts take place once every few thousand to million years, a Type I civilisation must master space travel to deflect space debris within that time, which should not be much of a problem. Ice ages may take place on a time scale of tens of thousands of years, and so a Type I civilisation must learn to modify the weather within that period.

dar nu, am perseverat si rezultatele se vad :))
Pentru aprofundare uite un link ce sta la mine in bookmark-uri de ceva timp si n-aveam cui si de ce sa-l dau:
http://www.mkaku.org/articles/index.html

"Firefox can't find the server at www.mkaku.org."

E haios Kaku asta, nu stiu insa cat de in serios merita luat.
Da' e haios oricum.
