    I believe anything lower from iron will make a star, when enough material added. Of course, one material from iron will give a much smaller lifespan for a star rather than hydrogen only.

    I think that an iron ball wouldn’t start a fusion. Might just jump right to a black hole if you added even more iron 🤔

      Damn now my curiosity is piqued.

      So let’s theoretically gather together an almighty ball of iron.

      As you add more, would it’s own gravity cause the density to increase to a point where it would collapse into a black hole?

      Would chocolate eclairs achieve fission? I need to submit these to Randall Munroe.

        There is a way to find that out. We can use Schwarzschild radius to find the point at which an objects radius crosses the event horizon and thus becomes a black hole; Rs=2GM/c2, Rs being the Schwarzschild radius, G being the gravitational constant (6.67xe-11), M being the things mass, and c being the speed of light.

        I believe so!

        I assume chocolate is made of lighter elements than iron so yeah, a big chocolate ball enough would become a star!
