The below three levels of energy usage have kicked around since 1964 in astronomy, and the discussions are very complex. This Professor Kaku knows that with our present technology, it would be sheer luck for us to pick up on other intelligent life in our galaxy, since there's so many ways to imagine communication that, given our development, and given the much more advanced development that virtually any extra-terrestial intelligences would be using, technologies beyond our ken, it is impossible to say whether or not our galaxy is teeming with communications or if we're the first to achieve even our low abilities. We could be like ants with modern scientific life on earth completely being unknown despite all the radio and tv signals pulsing through their tiny brains.
ET could be right here, right now, in a variety of ways that we simply cannot know of at this stage of our development.....er, except for maybe enlightened dudes who can pick up on them as devas, gods, etc. John, you should read up on this concept more: you below conclusions and your wordings indicate that you have barely scratched the surface...even to the point of misrepresenting the concept with incorrect subtleties....such as your use of the word "exhaust" below when there's no such consideration in the general concept that a civilization must exhaust any of its resources before it gets the technological ability to harness the energy of a star or a galaxy. Here's the wiki page for the concept: http://tinyurl.com/l3ql5 And I don't believe that the Star Wars scenario had any technology beyond Type II civilization. Type III technology is such a vaster abillity as to make harnessing a single star as insignificant as our "ant like" ability to harness coal and make steam.
