How is the sun stable? And it doesn't just go and burn out or explode in a colossal, cataclysmic event? It's almost like it's so perfectly designed to send the exact amount of heat. We are not quite sure exactly how it all works yet, but those stars are all doing that, and they're running us a fusion cycle inside their core. Eventually they do run out of fuel, and then they explode, that's a super nova. So, you know, we got to get out of the solar system before, before that happens likely. But really, we got problems to solve, like in the next forty years on.
