This is probably my favourite answer as of now.  Sad that it's technically wrong as stars don't burn or produce fire, but are undergoing fusion reaction. (Oxygen is a requirement for fire, but there is close to none in space.)

and yet we still stars to "burn out" as they near the end of their life cycles, and "burn their fuel" as their cores collapse.

furthermore, fire/flames as a chemical reaction, is the production of ionized gases that react by giving off heat and light. This most scientific definitions are the principle properties of plasma. Stars are essentially balls of plasma that are produced by the nuclear fusion reaction.

<p>Admittedly, I'm only 60 something episodes in, so this may already have an answer. 
However, as hypothetical as this may be, due to the fact it seems impossible, I'm simply curious what hardcore Fairy Tail fans think might happen if Natsu were able to eat the fire of a star? Just how strong might he become? How much might his physical form change? Would a star's gaseous fire even be compatible?
If you've got the knowledge, I wouldn't mind someone applying some "scifi" theoretical science and possibly even math to the answer. Looking for a great read of an answer! Good luck and thank you!</p>
