If someone says: "I am lying", are they telling the truth or are they lying? If they are lying, then they are telling the truth, which means that they are lying. If you went back in time to eliminate your grandfather, you will not have been born. But if you weren't born, how would you go back and eliminate your grandfather? If you went back in time and told einstein (Before he invented the Theory of General Relativity) and told him about the Theory of General Relativity, he would then go on to copy it. This would make future you go back in time and tell him about the Theory of General Relativity, which would repeat the process. So who invented the Theory of General Relativity? If you die in front of one person, they will get you help. But if you die in front of 50 people, nobody will do anything. This is because of the Bystander Effect, which makes everyone around you believe that somebody else is going to call for help. So how could you break this effect? okay thanks yall
