@Charles_in_Charge @NoDoxGregBrady I think about this shit untill i have a headache. Can we make a propulsion system with enough speed to visit the solar system in a reasonable amount of time? Even at the speed of light which we can never reach even the closest star is lifetimes away so if there are aliens or habitable worlds how could we reach them?why have we not seen any intelligent signals after nearly 80years of looking?Are there wormholes or shortcuts in spacetime? What was here before the big bang? How am i alive or more precisely, how is it possible i am a living self aware person when the odds of that are trillions to one or basically completely impossible?
