Right now it uses hydrogen, some day that runs out.
Then primary will be helium, and shit will suck but we can probably maintain life on Earth... But Mars would like be in flames.
Then the helium burns off, and a heavier element becomes primary fuel.
At that point, the flames of the sun likely extend out to the Earths orbit.
I skip steps sometimes and like I said, long enough timeline.
But you skipped the entire "red giant" step...
Before it can become a white dwarf, it's gonna barbecue our entire planet as a red giant...
yup. agreed on your timeline.
