Liu Cixin's "Three-Body Problem" mentions the "Law of the Black Forest" of the universe: in the universe, our planet should always be careful, just like the prey in the forest, always be careful of the hidden hunters in the forest, and if you are not careful, you will become the object of hunting. In fact, this is another version of nature, nature and the universe have something in common. Hawking has also warned humans not to send signals of contact to outer space to expose the location of the Earth.
It took hundreds of thousands of years for mankind to move from barbarism to civilization, and the bloody reality witnessed by upright people gradually expelled barbarism and cruelty with compassion and humanity, and it is still impossible to eliminate darkness, brutality, and massacre. In the vast universe, other civilizations may also be at different stages, and there may be various unexpected situations, such as the three-body planet with extremely scarce resources and extremely harsh environment, so Hawking and Liu Cixin's concerns are very reasonable.
When humanity eliminates the dark side of humanity such as selfishness, greed, ferocity, and possessiveness. Only then did true civilization become realized, and the natural laws of the weak and the strong could be truly changed. Do you think this day will come? Can it come?
