A very incredible sci-fi story being happened in the far distant future, a thousand year from now! Humans discovered a lot of new technologies. they built space elevator, ships moving with the near-light speed, we can revive the corpses! Humans don't literally speak orally but rather mentally by using braincaps which transport our thinking to another person's brain directly without speech. there're no crimes, religions, though there are still nations but they never conduct a war. we can make use of antimatter just like a kettle in kitchens now. Humans created an artificial mini black-hole which can level entirely planet if used malevolently. Yes, Science is like a kitchen knife. you can cut a bread or stab someone. ha ha.
