I thought that we already conclusively ruled out alien life by observing that there aren't huge, galaxy-sized smoke signals, generated from their massive candles to heat their galaxy-sized cottages? I mean, if aliens were out there, then surely they'd have sent us a notarized letter in the mail by now, as would any civilized culture. I bet they use really fancy quill pens, too!
...seriously though, I can't fathom why people are so caught up on the Star-Trek-like predictions where hyper-advanced aliens are still essentially humanoid. It's at least as absurd as [protocells](https://en.wikipedia.org/wiki/Protocell https://en.wikipedia.org/wiki/Protocell) assuming that all advanced life would be essentially protocelluar.

I can't fathom why people fail to realise that being bombarded for decades with pictures of hyper-advanced aliens still essentially humanoid somehow shapes the general public imagination regarding "aliens". /s
- kayaeb 7y agoSome people claim to have ruled out type III civilizations [1], which I think is what you're referring to. I thought also that some researchers claimed a star had signals consistent with a type II [2].

- dvdkhlng 7y agoAccording to recent news, the alien megastructure proposed in [2] may just be a shredded moon [3]. [3] http://www.astronomy.com/news/2019/09/evaporating-exomoon-could-explain-weird-light-patterns-of-tabbys-star http://www.astronomy.com/news/2019/09/evaporating-exomoon-co...
- stinky 7y agoThat's no moon...
- dogma1138 7y agoNo one seriously thought Tabby’s Star was aliens it was just weird.
- human20190310 7y agoIndeed. I suspect that the things we know almost nothing about (e.g. the nature of consciousness), and perhaps things we don't even suspect "exist", end up being far more important than physical expansion for intelligent beings over the long term. Communication itself might be of little interest to such beings.
