The external must remain the external. At least that's what I tend to believe. If and when the sky changes shape and color will you not still be the same being you've always been? It is probable.
Every molecule and atom that holds us together was first forged within our Sun. That is a fact. You can look it up if you'd like to. I urge you to.
And when you do... you must never take the Sun for granted again. It gives us light. It gives us life. It gives us hope.
