I completed last week the third part of the Three Body Problem trilogy. It was interesting but in this part things got wild! Every twist caught me out of guard. The physics got me lost most of the time (3D vs 4D, etc). But I like how Trisolarians learnt to lie and play long term. How reaching light speed was the proper solution and the most important thing: humans in a spaceship disconnected from Earth, took them 5 minutes to reach Totalitarianism. And all the theories about the Dark Forest hypothesis (Fermi Paradox), deterrence, and something a bit less sci-fi.
Destroying Earth using a 2D plane that sucks the surrounding 3D… but that would suck the whole universe… but that is a good tactic if you can live in 2D… not sure if that was a superior tactic to defeat your adversaries in the dark forest?
