Additionally, it is probably the smallest unit an immortal might notice. Or not. It depends on the scale of their immortality. An immortal who has been around for a billion years isn't going to notice 27 and a few days, but one who is around 100 years will notice almost a quart of their time.

See, time scales are weird in that they're hard to conceptualize. The dinosaurs died out 66 million years ago or enough time to put 10,000 days into those years 2,409,000 times, but you can put 10,000 days into the time the dinosaurs appeared during the Triassic to when they died 6,789,000 times. You see, there was more time between the T-Rex and the first dinosaurs than between us and the last T-Rex.

Google tells me that 14 billion years is 5,110,000,000,000 days and that 5,110,000,000,000/10,000 is 511,000,000. Let's call 10,000 days a Tool Unit. There have been 511,000,000 Tool Units since the Universe began, assuming we're even close in our estimates of Its age.

It is estimated that every star in the universe will be dead in 100 trillion years. That's 3.65e+12 Tool Units or 3,650,000,000,000 in real numbers.

3,650,000,000,000 ten thousand days. The crazy thing is that this time will pass. It will eventually expire. I won't be there to see it. Neither will you, or the Earth, or the Sun or-- hell-- anything really, but the universe will get there, counting its clock every planck time (0.00000000000000000000000000000000000000000000000539 of a Tool Unit), millisecond, second, minute, hour, day, year, and so on until there is nothing at all.

10,000 Days is a ReQuest.
