If we could in theory actually contact et's, wouldn't it make sense that their
planet is orbiting a star and emitting "pink-noise" radio signals, much like earth does as it orbits the sun? Hmmm... allow me to elaborate. By pink-noise I mean the random radio signals that we send out for radio, television, basic communications. And if these signals act like light wouldn't they theororetically be pulled into the "groove" that the earth's orbit dig's into space as it spins around the sun? Should astronomers not be looking for planets, but the wake left in their trails? I'm also curious to what you send out as signals. I think it'd be a good idea to recreate the scenario from "Close Encounters." Like right a piece of music to sent out, but begin with a signal of 3bps, have the signal pulse and pause for an equal time and allow the signals pitch to increase and duration increase at a steady rate until the pitch reaches 180bpm (i think) and have the instruments tuned to a-441 since its a number divisible by three. steve(vote for me2020!) http://members.aol.com/_ht_a/whyweig...mtbrand=AOL_US "music is like this porthole into another world... the world of truth."- trey Stick it to the man in 2004, wait? who's the green candidate in 2004? |

The problem with looking for broad spectrum radio noise (be it pink, white or brown) is that there are natural radio noise sources, like stars, that are much stronger than the random radio signals given off by a civilization with a technology equivalent to our own. If the little green men want to be heard, then we expect them to transmit a non-noisy signal which can be picked out from the noisy background. And if these signals act like light wouldn't they theororetically be pulled into the "groove" that the earth's orbit dig's into space as it spins around the sun? You've completely lost me on this one. What makes you think light gets pulled into a "groove"? Have you ever seen light wakes that are left by other planets, or by the Moon? I haven't and I'd expect radio wakes to be similarly difficult to detect even from short distances. I'm also curious to what you send out as signals.

My understanding is that the achievable data rate over the sort of signal that we are capable of transmitting over interstellar distances is a fraction of a bit per second, so analogue audio signals are not suitable. Anyway, we don't actually know that the ETs have ears. Binary data signals are more sensible, possibly using Frequency Switched Keying, or by simply switching the carrier signal on and off to send one and zero bits. Probably the most significant thing that you can say in such a transmission is an indication that we are here and we don't mind anyone knowing, and that message can be achieved by simply sending an unmodulated narrow band carrier wave. -- Mike Williams Gentleman of Leisure |

Is not pink noise gaussian?
what's guassian mean? steve(vote for me2020!) http://members.aol.com/_ht_a/whyweig...mtbrand=AOL_US "music is like this porthole into another world... the world of truth."- trey Stick it to the man in 2004, wait? who's the green candidate in 2004? |

e. What makes you think light gets
pulled into a "groove"? I guess it's just one of the ways a being can interpret the general theory of relativity steve(vote for me2020!) http://members.aol.com/_ht_a/whyweig...mtbrand=AOL_US "music is like this porthole into another world... the world of truth."- trey Stick it to the man in 2004, wait? who's the green candidate in 2004? |
