it's basic logic. there are 2 forces acting on the sun. gravitation pulls matter towards the center because it is an attractive force and fusion at the core generates photons that move outward.

right now the outgoing photons push everything away from the core and some of them escape into space to end up back on earth as a source of energy that enables all life.

eventually, enough of the mass will be converted to photons and the outward flow of electrons will be less. the theory says that at some point the sun will expand but i don't really understand why. the models basically say that assuming a certain density of matter distribution some computer simulations show that the sun will expand before it eventually collapses into a white dwarf which is basically a very dense ball of metal flowing in space.

anyway, the theory checks out. if you burn trees then you will eventually run out of trees so the same principle works for the sun. it is a finite resource and eventually the material for fusion reactions will run out unless we figure out how to add more fuel to the fusion furnace.

hope that helps. good luck on your journey orbiting your father, mother, and future descendants.
