It canāt due to some basic communication basics. The truth is that the radio or TV signals from the most powerful stations are so weak by the time they pass Uranus that they are not recoverable.

But considering this and the other thread, you are having some sort of crisis, regarding the permanence of our actions, wich is a great and very vast topic. But it is the oposite of punk. 1 Link to comment Share on other sites More sharing options...

But we know how exoplanets are discovered and we know how to analyze the chemistry of the most irradiated elements. And let's not mention the fact that in 20 or 30 years we will have a much more powerful telescope than the unstable and precarious James Webb.

Orwar Posted January 24, 2022 Share Posted January 24, 2022 Ā Ā Having better telescopes in the future doesn't change anything about how radio waves are dispersed in space, though. Ā Ā The point is, by the time radio waves leave our solar system, they're practically indistinguishable from the naturally occurring radio waves already in space. Thus, there won't be anything much for a far-distant civilizations to detect. Ā Ā "Shostak calculates that Nasa's recent broadcast of Beatles music towards Polaris, the North Star, using a 210ft antenna and 20kW of power, would require any potential aliens to have an antenna seven miles across to be aware of it. To actually receive it as music, this would need to be increased to a 500-mile wide antenna."

"Radio" describes a subset of the electromagnetic spectrum on which we transmit information. The entire spectrum is the only way energy/information can be projected. Orwar's explanation of signal-to-noise ratio (SNR) applies to any energy you might project. His explanation is also superfluous in situations where the SNR is already too low for interpretation at the source. 2 2 Link to comment Share on other sites More sharing options...

Cinnamon Mistwood Posted January 24, 2022 Share Posted January 24, 2022 (edited) @Tama SukiĀ several people in these fora already have you on ignore, so you will not get as many replies as you have in the past.Ā You have fun and thought-provoking ideas for posts, but unfortunately in a page or two they become flame-fests and personal insults. They then predictably get locked.Ā This wave thread may not have been well thought out because there are science nerds, engineers, and doctors of various sorts here to call out the incorrect thinking and fallacies and explain in aĀ nauseatingly long and boring maths lecturesĀ where you went wrong(I actually enjoy those posts a great deal š.)Ā Yes, you can block/ignore people and not see their posts.
