Don't use the sun as an amplification vector and attract Extraterrestrial attention!

Haha, Three Body is a great fiction story

Spoiler alert, that's still in my TOREAD list :/

Sorry :( You should still definitely read it! It's an excellent story.

Everyone remembers what Arecibo was originally built for right?

I don't, and for those who like me didn't know:

Apparently it was initially meant to help identify re-entering warheads so that they could be shot down before hitting their targets.

Or pick up radio signals from Russia when they bounced off the moon... https://steveblank.com/secret-history/

The article mentions searching for gravitational waves. Anyone have info on how they might accomplish that via radio telescope?

Ah hah! I thought it might be something like that, but figured there was something I wasn't considering. Thanks for the link.

Strange that the last news from FAST was on August 9th: http://fast.bao.ac.cn/en/index_eng.html

Basically for month and a half pretty much no press releases from them.

I didn't see it in the article, but I recently heard that NIST played a role in the design of this telescope.

That is the original ap.org link

Sorry your submission didn't come out on top, but thanks for the link! We've updated the URL of this one from http://phys.org/news/2016-09-china-world-largest-radio-teles....

I love the light handed, thoughtful, considered moderation on HN. The contrast with Stack Overflow (as per an active thread at the moment) is stark. Well done, please keep it up.
