This was my science project for the day. Clearly, this picture is about stars. It’s about the order in which the stars form. As you can see, our star does not have any other form. The red giant for example, has two different forms. First is the red giant, then the white dwarf, then the black dwarf. But the super nova, on the other hand, depends on how high the mass is. The black hole has super high mass, but the neutron star/pulsar only has high mass and only has a fraction of the mass of a black hole. But the white and black dwarf stars have a very low amount of mass, and the older they get, the lower the mass gets. I hope that explains what the picture above is talking about. Bye.
