The Life and Death of Stars

Every star you see is actually a ticking time bomb fighting for its life. It is a constant

war called hydrostatic equilibrium where gravity tries to crush the star inward while nuclear fusion

pushes back out. As long as they burn hydrogen, they stay alive. But for massive

stars, the moment they try to fuse iron, it is game over. Iron drains energy

instead of creating it, causing the core to instantly collapse and explode into

a supernova. You end up with a dense neutron star or a black hole so strong not

even light escapes. The universe is expanding, and we are just watching the aftermath.
