Stars don’t die because their fuel runs out. Stars change their colour and brightness from time to time. Large numbers of helium burning stars are dying prematurely according to traditional sun theory. Half of the stars skip the red giant phase. There is no nuclear power plant inside stars. Stars are electrically connected and externally powered.
Scientific theories change very slowly, and the traditional understanding of how suns work is way behind what the data is now suggesting. Suns receive energy from the galaxies of which they are a part. Stars are not energetically isolated. Planets receive energy from solar sources – lightning, aurora, solar wind etc. Stars absorb energy from the galaxies, and send energy to planets.
Stars form on filaments, in threads.
