@OB
What? Josh was not talking about the moons circular orbit. He meant that as the moon travels outward, it is held by less and less of Earth’s gravity. Therefore, as time goes on, the moon wouldn’t just be traveling outward at the same speed, but it would be accelerating away. I’d say that’s very relevant.

@Josh

The period of the moons orbit is not a relevant variable in these calculations.

What about the compounding effect. In 10,000 years won’t the fact that the moon is further away mean that its distance travelled per year will have increased (due to the corrosponding reduction of gravitational pull)? I still don’t think its a concern for our species, but wouldn’t that cut your estimate about in half? Meaning that the moon’s departure will be a problem long before the explosion of the sun?
