re: 3 Body Problem - Netflix

I believe they ended up cutting weight and using 300 nukes, but your point still stands.

I don’t exactly recall everything from the books and need to read again. But..

There is still a civilization on the tri-Solar planet. They still need to predict the movements (it’s impossible though) or they will eventually be wiped out for good.

The books do a much better job with the wallfacers. Maybe the show will also in season 2. Basically they do things in a way that looks like they are attempting one thing but there is another secret idea in there that only they know.
