AI Thread Summary
The discussion centers on whether cosmic electromagnetic radiation follows Gaussian characteristics or if it is uniformly distributed across wavelengths. Participants express curiosity about the existence of low noise areas in the electromagnetic spectrum, particularly in relation to the search for extraterrestrial intelligence (SETI). There is also a question regarding how instruments convert electromagnetic vibrations into sound, especially given the blackbody spectrum at approximately 3 degrees Kelvin. The idea of focusing SETI efforts on low noise regions is proposed as a strategy for clearer communication. Overall, the conversation highlights the complexities of cosmic electromagnetic radiation and its implications for scientific research.

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...

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Our Beautiful Universe - Photos and Videos'

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b. I start this...
