Tama Suki Posted January 24, 2022 Author Share Posted January 24, 2022 6 hours ago, Orwar said: Having better telescopes in the future doesn't change anything about how radio waves are dispersed in space, though. 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. "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."

But I've never talked about noise and radio waves. We certainly won't be able to see any stars in the sky if the photons decay. I think that now that we have overcome this obstacle we can continue more easily in our gracious and nice chat, thank you. Link to comment Share on other sites More sharing options...

Waves is waves. Orwar's signal-to-noise ratio explanation covers the entire electromagnetic spectrum, from gamma rays to VLF (Very Low Frequency).

I understand that maybe adding links on links can be a tiring exercise, maybe next time. A more complete and exhaustive report would be welcome. When redshift will be in a spectrum impossible to perceive with any instrument, perhaps, as Lawrence Krauss says, astrophysics will become a kind of philosophy because we will have no way of assuming that there is anything in the universe beyond our galaxy. I don't know when that will happen, perhaps in another 13.7 billion years. Maybe my post 13.7 billion years from now will make more sense to you, I'm a patient.

Just prepare the links and put them on the table at the appropriate time. I remember doing this a lot when I was doing ornithology and discussing birds with friends years ago. I learned the names of many exotic species. It is a fun and useful hobby as long as you are in the right context. 1 Link to comment Share on other sites More sharing options...

ETA: On Saturday, we had a swift and steady 5°F breeze from the west, in excess of the minimum cruising speed for the hawks and falcons in my area. This affords them the ability to hover by flying into the wind. I imagine this is advantageous, as their visual systems needn't subtract away ground motion while searching for prey. It's fun to see them riding thermals over fields on calm days, but I love to see them take advantage of high winds. Saturday felt unusual, though. On the short drive from my home to my emergency backup kid, I watched a total of six hawks hovering over road shoulders. This alone would be remarkable, but I also spotted two field mice scurrying across the road at other points on the trip. That's even more remarkable. Though I can't think of a reason a brutal cold wind would drive mice to risk road crossings, I do wonder if the hawks knew a good thing when they spotted it.
