Carl Sagan had some interesting concepts about intelligent civilizations such as what we deem humans to be doing. He had intelligent civilizations categorized as a class I, class II, and class III and suggested that if we met a more intelligent species, one that had been intelligent for thousands and thousands of years, they would have gotten to the point where they could've controlled energy from their own sun, and therefore the temperature, atmosphere, and everything else on their planet.
In that case they would have abundant and free energy and they could use that energy to travel through the solar system, through their galaxy, and manipulate space-time. This may seem very much into the science fiction realm, but he's making perfectly good sense as he explains this. You can also watch his on YouTube on this topic, if you are wondering what I'm talking.
Is it possible to control our Sun? If we can control our Sun, we wouldn't have to worry about climate change, as we would be in control. Not long ago, there was an interesting feature discussing this. Science at NASA Online Newsletter posted an interesting story on June 28, 2012 and you can view the online video version on YouTube by searching; "ScienceCasts: Hidden Magnetic Portals Around Earth," which stated that;
"A NASA-sponsored researcher at the University of Iowa has developed a way for spacecraft to hunt down hidden magnetic portals in the vicinity of Earth. These portals link the magnetic field of our planet to that of the sun."
Now then, perhaps we can use this someday to control the Sun, or adjust our Earth's atmospheric heat. Sounds like Science Fiction - well, there have been some Science Fiction stories about such things such as;
1. Sunstroke - Arthur C. Clarke
2. The Naked Sun - Isaac Asimov
We ought to use these portals to generate energy, and to adjust our ice melt at the poles and solar radiation to cool the planet as we humans feel necessary. Eventually, we can use these portals to send instructions to control our Sun. If we could send information, energy, and directed beams through these portals, we should be able to control what is coming back, and therefore control the intensity of the Sun's radiation as it hits our atmosphere.
If we could do this, we would go from a class I civilization to a class II as per Carl Sagan theory. Okay so, enough science fiction for today, and futurists projections. Indeed I hope you will please consider all this and think on it.
