vivian, even if what you say applies. If, as Scientific Amercan wrote " -- will add LUSTER to the Mlky Way--, it would be LUSTER in what shines in the MILKY way?, what is it? STARS, NOVAE, or the gases they iluminate, but STARS that shine.
Your point was about the sun absorbing material to remain shining for long (actually, that would shorten it's lifespan, but whatever), your quote was about something entirely different. Sorry, but you don't get to retro-fit your erroneous claims and now try to say they match something completely different.
just asking: both sides of an equation balance out to zero, but there is there not value on both sides? adding up now , but aslo cancelling out at the end?
Define what you mean by value.
