Ashes to Ashes
In however many billions of years, planet earth will cease to exist when our sun explodes. Earth won’t burn, because burning requires a time lapse, and earth itself won’t explode, at least not in the context humans are familiar with, because we will liquidate instantly, our atoms gone faster than any increment of time humanity uses currently.
It won’t be like a Tom Cruise movie or even like an atomic bomb dropping on a city. There will be no time for humans to react, to look up, because it will happen faster than any motion humans can make inherently, more quickly than blinking. You likely wouldn‘t even register the blinding light of it, because by the time the light reached your eyes, every atom that makes up your body will be obliterated, the DNA in your cells unraveling backwards, faster than the back button on your laptop when you click it repeatedly or someone making an Irish exit at a large, uncomfortable family gathering.
Ashes to ashes. In less than a nanosecond of a nanosecond of a nanosecond. You get it. You wouldn’t even turn to dust. Earth‘s life span as a planet will have been insignificant in relation to that of the universe, humanity snuffed out before the breath even reaches the candle.
