Re: Noise and Data - Radio waves and other things

[color=#000000:post_uid0]Personally, I have always thought that the SETI crowd are a bit wrongheaded.  It is highly unlikely that they will find anything at all by listening to radiowaves from deep space.

Our data systems are based on ones and zeroes, or states of on and off-if you like it that way.  We know nothing about potential extraterrestrial's data systems-or on what band of the spectrum they transmit-if at all.  What if they transmit data using cosmic rays-or encoded bursts of gamma radiation?  Messages from across the void of space are likely to be interpreted as static-unless by some obscenely improbably chance, they happen to develop or have developed an interface that is compatible with our antennae.

We're like indians, trying to send smoke signals to a man over the horizon-who is watching for semaphor signals.  We see white objects waving, and think it to be some sort of bird.  He sees smoke clouds and thinks it a forest fire.
Did I mention that our smoke signals are in Navajo and his semphor flag-waving is in Greek?[/color:post_uid0]
