energy and iron. heat death does not mean no matter or energy, it means that there is no usable energy (maximum entropy). the thing most people misunderstand about the concept of work, is that you have to have a differential in order to do work. if everything is at the same temperature, you can’t extract any work from it, without adding energy to the system, and at heat death there is no way to get that. also, iron, because all elements transmute to it over time, so ya, iron stars are still floating around.
