i realized this at a very very young age in fourth grade when my teacher said the order goes city, country, continent, planet, solar system, galaxy, universe, thats it...whats after universe? it cant just STOP...there CANT be an end to existance it is impossible to comprehend if you think about it. it also makes you feel very insignificant tot hink your 5-6 feet tall in a univers with incalcuable size. and if there is an end to the universe...how is that possible..i mean do you just come to a stop and eveything ends, like...something has to be in something else, that si where infinity comes from, therefore the universe is never ending
