Deep space thoughts...

Saw some old dreams tonight.  The ones I saw when I was a little child.  Like the movie.  Many dreams are like movies, or to be more precise, like computer games.  Same characters look different when you perceive them through an adult brain.  Couldn't sleep the rest of the night.  Today there is an early meeting at work.

Also, it's the end of shuttle Discovery's mission and it will be retired by the end of day.  A thought occurred to me: if there would be alien races and they would scan different planets for signs of intelligent life, it is possible they would use different scanning parameters than Earthly scientists, searching not for infrared radiation, or signs of carbon/oxygen/bacteria in the environment of the planet, but certain brain wavelengths.  This way they would be able to find "alien brothers and sisters" and not bother with less developed inhabitants of the Universe.  Because it would be a waste of a lot of fuel to fly from the far reaches of galaxy just to find out the animal/bird/reptile life on some planet.  Maybe alien life is out there, but we as humanity are still not detectable on their long-range scanners.
