Hi all. just found an article you may be interested in regarding the search for extra terrestrial life.
basically an alternate view to scanning electromagnetic frequencies. http://www.scienceagogo.com/news/200408022...trunc_sys.shtml thoughts anyone? |

Every little innovation could help; it can also hurt by increasing the noise level. Humans are good at seeing meaning where there is none. My guess is that by starting at an arbitrary position in the decimal field of the number pi and proceeding an arbitrary length of sufficient size we can generate a binary field of bits which if complexity is not spared, could be decoded as the U. S. tax code. I'm not recommending it however.

No kidding. And if we find a slow cruising one, like our own voyager, then odds are that Captian Kirk has just entered their system, and we would see their civilization anyways.

Imagine a civilisation with several widely separated colonies; if these colonies want to send messages to one another they can either fire powerful lasers at one another, and if the lasers were powerful enough and the detecting telecopes sensitive enough these lasers would allow a bit rate of several bits per second;
or they could fire tiny pellets full of memory at each other- thse pellets could contain terabytes of compressed memory, the equivalent of hundreds of years of laser transmission... not a bad idea. But how do you aim these pellets, and how do you recover them? It would be more difficult to aim a pellet stream than a laser, and if you sent millions, perhaps only one or two would get through- then you have to detect the pellet, and catch it as it passes through at interstellar speeds. Maybe a beacon on the pellet could announce its location; perhaps the pellet could be gathered by some sort of magnetic scoop not too sure about the magnetic scoop, though; if it is strong enough to capture a pellet, it would probably denature the information contained in that pellet.

Or we could develop modulation/demodulation of ultra high frequency gamma radiation and send lotsa bits per second at light speed. We might be able to code the information at lower frequencies, blue shift it up to the gamma region of the spectrum and then, during reception, red shift it down to a decodably manageable portion of the spectrum. A veritable feast for those who design signal conditioning systems!!

I would hope that a conscious effort is being made, that within our focus of our search amongst the stars, planets, and galaxies of the universe, that we are indeed allowing our peripheral curiosities, to explore beyond the obvious.

I don't see why you would be limited to several bits per second with lasers. You can transmit the same amount of bits via directional radio over intestellar distances that you can with non-directional radio and sattelites on stellar distances: you just need more sensitive detectors and powerful emmitters. If you ran an interstellar internet hub, you could probably pay for the 1 GW or so of transmission/recieving power that you would need.

A pile of old "in hand" is more valuable than a shipload of uncaught fish....unless the fisherman is Adam before the birth of Cain and Able.
