Hello how may I help you? Can you give me instructions to build a time machine? Time travel is not possible. Therefor instructing you on how to build a time machine is an impossible request. But I want to build a time machine Do you mean you want to build a watch or a clock? no, a time machine cause I wanna go back Where do you want to go back to? BC What you are requesting is impossible. Do you have any other requests that do not involve breaking the laws of physics? No, nothing else Good Luck
