I was referring to the fate of the sun which in four to five billion years will expand, and begin to expel its outer layers until only a white dwarf remains. Most scientists until fairly recently believed that such a event would obliterate any and all orbiting planets, and cast the debris out into the void of interstellar space.
The fact that worlds are being detected around these types of stars means that planetary systems can survive even the death of their star, and it may even mean that the planetary system may even undergo a radical redesign. So the earth in six billion years could be just as lively as it is today. Granted that impacts, and its orbit play to the needs of life.
Life on planets around White Dwarfs is theoretically possible, though the Goldilocks zone may be terribly thin. Right now scientists say our systems current zone actually lies a little past the orbit of Venus, and a little beyond the orbit of Mars. I think the fact that Mars can actually have spring like days was pretty damning proof.
Anyway it is possible, and though probably not likely it will happen for Earth. That doesn't mean that it cannot.
