I mean, observing the effects of a 21.1cm hydrogen line that came about due to events that took place at least 12 billion years ago should be impossible.
It was really really tough. The signal over background ratio is of about 1/10000. But astronomers managed to build an apparatus and an analysis method allowing to extract this signal.
However, I was not able to find the "something stupid" you mentioned here:
Well, if you find it, you will definitely notice it is stupid. Hint: check all comments to my post.
Thank you for your reply. I have scoured the post much like the cosmologists looking for evidence from the formative years of the Universe. Well, definitely not that thoroughly. But apart from the link to SETi, I can't find anything else. I'm certain I need help from a more experienced person to find something stupid in this post :)
You also need to scour the comments :p
Okay. Let me do that again :)
Have you found it?
The party is over. I have found it. Somehow, I feel a sense of satisfaction even though I found it late with two different pointers. And it is in French!
Thanks for your patience!
Ahaha ^^
