  1. +Melroy van den Berg The sun dies. Depending on the star's size, our sun will begin to use up its hydrogen fuel and become a red giant star, and begin making heavier elements than just helium such as producing carbon, this is thermonuclear fusion and its system the way it does it and the amount of energy it then releases is even greater, the size of the star becomes huge in the red giant phase, it's density decreases because it's releasing all the mass in the form of energy and expands in volume and it's density, gravity isn't strong enough to keep the outer layers together, so it starts exploding immense layers as well as let layers to drift off into space (it's not a super nova in scale, these explosions would be like burbs relative to other cosmological explosions). Eventually what is left of a star the size of our sun is a white dwarf, essentially very dense material made of carbon and other elements, not to include any new iron, our sun isn't massive enough enough to ever produce iron or many other elements even below iron, I think nitrogen and oxygen are among the heaviest our sun will create. Bigger stars will continue the fusion process until iron develops in their core, at which point iron actually absorbs energy rather than releasing energy so gravity wins and the the star collapses from the outside in, suddenly the energy from the collapsing star reaches a critical amount in the center core and it bounces back out causing an explosion, a super nova, expelling all the material outward so fast the elements continue to fusion to the rest of the heavier elements above iron all the way to uranium. What is then left behind in the core is a neutron star, extremely dense material, with degenerate matter extremely dense thus heavy, it may not have any protons, only neutrons because the density thus gravity is so strong only neutrons can exist, but they decay slowly in to electrons and/or protons; thus they all produce very strong magnetic fields. If a neutron star spins as most do they produce a pulsar star intense magnetic radiation. And appears that new formed pulsar stars are actually the most extreme magnetic thing to be observed in space, a magnetar an extremely magnet pulsar star. If the the super massive star is sufficient in size it will still rebound and explode creating a supernova, but instead of a neutron star, pulsar, or magnetar, it creates a black hole, the core essentially falls into 0 volume, or an undefined density that is mass is divided by 0. All the energy at the core is focused onto space-time, the matter is utterly destroyed, the energy remains with a locality transferred directly onto space-time, and known physics at this singularity breaks down, because it gives you an undefined number divide by 0 error aka you're relationships in your equations are no longer have a relationship that can describe anything useful. However, the outside of the black hole still interacts and can be described, its where you get the event horizon, and what black holes do to the surrounding area, the event horizon actually does grow in size the more massive the black hole. At the hart of the singularity of the black hole however, this isn't any size, there's no volume anymore. But lots of mass, which again, can be increased as things fall onto it.
