Ok everyone, ever since i was 16 i have been studying this kind of stuff. Anyways I'm now 18 and a senior in high school and really want to get one of my theories out there. Im not giving my complete theory but i want you guys to give me straight answers on this. We all know we were basically made of stardust. Well everything even atoms are made of mostly hydrogen. Well someday hydrogen will run out and we'l have no more left. This is right isn't it? Hydrogen combines with helium which creates massive elements. So basically someday down the road when stars can no longer exist because of no more hydrogen then it would be impossible for any kind of human life to exist too right? Also is there a site (this is off topic) where i can post my own info and copyright my own theory so no one can steal it? I wanted to use the physic forums for this because you guys are the most intelligent people i ever heard on forums about this kind of stuff. This is just a hobby of mine but I'm trying to make stuff that gets out there someday and I'm hoping i only get more clever since I'm already making my theories up at only 18 years old. Anyways thanks for reading and tell me what you guy think about hydrogen running out someday.
