ElectricalUncleSam,
I don't know, eUncleSam. It sounds like a closed-minded response. There is a lot we don't know about the universe. And it is true that all the
top-minds' theories, like Michio Kaku, Stephen Hawking and others, are just that. They are theories or guesses based on the available data they have
at the current time. And each of them are humble enough to say so.
Best question to ask yourself is this: The known universe is 14 billiion years old. Our solar system and planet has only been around 4 - 5 billion
years. Humans have been roaming the earth, supposedly, tens of thousands of years. Humans have only occupied known time for only a drop of a bucket.
Ask yourself how would a civilization be if it was 10,000 years older than us? Better yet, how would we perceive a civlization that is a million
years old? Or a billion years old?! They could possibly god-like in our eyes because of their technology is so alien and so wonderful. Do not
assume alien life in the universe develops exactly like humans do.
You should read Michio Kaku's and Stephen Hawkings' books. Very intriguing and good for the mind. It kinda puts you in perspective with our little
pond and the universe.
As for the types of civilization, Dr. Kaku did not invent it. It was created by a Russian phycisist, named Nikolai Kardashev. And the types of
civlization is called the Kardashev scale. See link...
