Discussion Overview

The discussion revolves around the characteristics of cosmic electromagnetic radiation, specifically whether it follows Gaussian distribution or if the noise is uniformly distributed across all wavelengths. Participants also explore implications for detecting signals, such as those relevant to the SETI project.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions whether cosmic electromagnetic emitters exhibit Gaussian characteristics or if noise is uniformly distributed across wavelengths.
  • Another participant expresses curiosity about how space instruments convert electromagnetic vibrations into sound.
  • A third participant mentions the blackbody spectrum at approximately 3 degrees Kelvin as a relevant factor.
  • A later reply raises the idea that the SETI project might focus on low noise areas for better signal detection, though this is contingent on the existence of such areas.

Areas of Agreement / Disagreement

Participants express curiosity and raise questions, but there is no consensus on the characteristics of electromagnetic noise or its implications for signal detection.

Contextual Notes

Participants do not clarify assumptions regarding the definitions of "noise" or "tranquility" in electromagnetic radiation, leaving these terms open to interpretation.

Hi,

Does the cosmic electromagnetic emitters, if viewed in the function of electromagnetic intensity and in the particular wave length, follow the gaussian characteristics or is the noise uniformly distributed over all wavelengths? I.e. is there "tranquility" in intensity (or least amount of noise) in particular area of electromagnetic radiation in the universe?

Thanks!

I actually wonder the same thing!

What i also don't understand is how the instruments in space can "convert" the electromagnetic vibrations from the object into sound ?
 
its a blackbody spectrum at about 3 degrees kelvin.
 
Hi guys,

Well the reason I asked is that I was wondering one day if the SETI-project is concentrating these low noise areas (if there are any of course). I mean If was to get a message heard I would rather do it in the most noise-free place I could find...
