The Chemical Composition of the Universe

I think it's really understanding how galaxies evolve with time through the basic building blocks, which are stars. And we don't know a lot of it because of the diversity. It may seem like, well, yeah, we know these stars make carbon, but there's so many internal complexities. If you take a galaxy and you map the chemical composition of it, it's not going to be a straight line for every element. We understand it by and large, but the intricacies of it is what we don't understand. See, that's the worrying thing, though. Anyone here who, if they were given a chemistry set? How do I make everything explode?
