OK this makes me so mad cuz it confuses the hell outta me. Ok scientists have been saying that the universe expands and contracts you know gets bigger and smaller. But how can something that has no end possibly grow and shrink?? Doesnt it have to have an end somewhere?? But then I mean it cant be like your flyin and all of a sudden you smash into the wall. Cuz what would the wall be made of? and there would have to be something on the other side. But what if lets say well ill use an example lets say the Universe was 100 ft wide (just an example) maybe when you get to the end of the hundred feet you just end up back at one?? You know what i mean like youll just keep flying not in circles but like as soon as you get to the end your right back in the beggining? I dunno what do you guys think??
