Radio waves may also coming out in favor of digital solutions on other planets. If you want to find intelligent life elsewhere, one must therefore look for the light from their cities instead of listening, researchers believe. By Thomas AE Andersen 8 , 2011 at. 07:15
In the search for intelligent life elsewhere in the universe, we have so far primarily been searching for radio signals and ultra-short laser pulses. Now a group of researchers instead suggested that we should look for the light from their cities.
Our technology is moving increasingly away from broadcasting via radio waves over for transmission via cables and optical fibers. Thus we become harder to detect for alien civilizations. If the same applies to other civilizations, luce & light then artificial lights the best way to find them, the researchers believe.
If you look at the Earth at night, it is very obvious that this intelligent life. Avi Loeb admits to onorbit.com that it is a shot in the dark, but it will not require additional resources, and if it did, it would be revolutionary. So when we finally that we are not alone in the Universe.
As with other methods of hunting for intelligent life is the prerequisite course, that other civilizations use the same technologies as we do on Earth. Scientists believe that this is a reasonable assumption, since every civilization that develops in the light from the nearest star, presumably artificial lighting luce & light that can be used at night. Light from alien civilizations
The two scientists propose to examine variations in the light from planets as they move around their parent star. This requires, however, that the light from these civilizations cities can be separated from the light from the parent star.
As the planet revolves around the star, it undergoes the same phases as the moon. When it is dark, there may appear more artificial light from the night side than reflected from the day side. This means that the total amount of light emanating from a plane indicated by cities will vary in a way which is different from planets outside cities.
However, it will require a new generation of telescopes to take advantage of this new method. The technique, which we have mastered today, can initially be tested with bodies at the edge of our solar system. Cities can be seen in the Kuiper Belt
The researchers' studies show that today's telescopes on Earth should see the light of a city the size of Tokyo on an object that is out in the Kuiper Belt. The Kuiper belt is the area about 50 astronomical units from the Sun, which dwarf are Pluto, Eris, and thousands of other smaller bodies are. If there were towns on some of the bodies out there, we should be able to see them.
"It is extremely unlikely that there are alien cities on the edge of our solar system, but the nature of research is to find a method and look for. Before Galileo, it was conventional wisdom that heavier bodies will fall faster than lighter. He tested the theory and found that they fall at the same speed. "

The search for technological life on other planets could be more futile than to buy lottery tickets, but to buy lottery tickets so you win garateret not and the same must be said of the search. Searching can not find nothing.

It is the need for money for new telescopes that have generated this absurd idea. When astronomers luce & light are looking to find investors, the argument luce & light could be understood by all. So even the title of Professor at Harvard no guarantee serious work.
Other civilizations out there are also using radar like we do here on Earth. Any planet that uses satellites are tracking radar, so they can keep track of these and wreckage. Radar systems are high power with a reach far into space and in all directions, because the antennas rotation and also because most planets spin. Our signals began in earnest in 1941 with the English stations, which introduced 3 GHz with 350-450 KW and later up to 850 KW (cavity magnetron) and these signals have now reached approx. 70 light years into space. There are stations today, with 2 MW of power and very large antennas that vill be "heard" many thousands of light years away, that you can be provided receiving equipment that just looks like more or less the ones we use.
It sounds at least as a method which increases the chance
