It’s just a thought and I sure it’s been discussed. But if radio waves are so problematic and slow wouldn’t a technologically advanced species, use light in deferent spectrums to send a signal? Are we looking for the right source of communication ? Al |

Are we looking for the right source of communication ? Radio isn't slow or problematic; in fact, it's relatively "fast" and easy to detect and work with. - Radio travels at the speed of light in a vacuum, so it's not slow. - Artificial radio transmissions are comparatively easy to detect against the background noise of space. - Radio transmission is relatively "cheap" and easy to accomplish, especially directed, narrow beam signals, though it does become more costly at longer distances. In terms of speed, it doesn't matter what other part of the spectrum ET uses since anything in the electromagnetic spectrum travels at the same speed in a vacuum. Radio is cheaper and easier to generate than X-Rays or Gamma Rays. It *has* been postulated, however, that ET may use the visible light part of the spectrum instead, so you're on to something there. There is an "Optical SETI" division of the SETI Institute though it is not as well funded or supported as radio searches. If ET is using some other, more complicated or advanced form of communication, there's not a whole lot we can do about it since we don't yet have the technological capability to easily detect it. If they're embedding information into gravity waves somehow and sending them at Earth, we'd be out of luck as far as detecting it for the foreseeable short term future. |

Are we looking for the right source of communication ? . . . there is - maybe - a possibility that they're using 'Pulsed Tachyon Beaming' - embeddin' said Info's within that space > will get back @ a later date regarding said matters . . . meantime, neXt: BOINC Wiki . . .
