Well I'm a pretty young kid. But i know a lot about physics and a special astronomy. Me and another very intelligent Friend were talking about something today. The first rule of thermodynamic states that energy cant be created nor destroyed. Matter is a type of energy but in a more compact state (I'm not Sure if I'm correct). At the edge of the universe the universe is expanding/Collapsing. If it is expanding more and more of the universe is being created out of nothing. Wouldn't this be matter being Created and if/or it were collapsing were would all the matter go therefore it would be destroyed? Also All the matter being sucked into black holes does the intense gravity destroy anything being sucked in? Thank you for all your answers. O yes i forgot I'm 12 turning 13 if any of you wanted to know.
