    I agree with rhe sentiment but small correction, the moon is falling away from earth.

      Well that might depend?

      Because as far as orbital mechanics are concerned it’s falling toward us (because that’s what orbiting usually involves) but because the orbit is slowly getting larger it’s falling is slowed, maybe? Well can’t really be that because the speed should be pretty constant?

      Huh, that’s kinda a hard thing to answer comprehensively for someone who didn’t take that astrophysics course everyone else took…

        Orbits are closer to spirals, earth and the moon are moving around the sun, with the moon spiraling around earth. It’s just a larger and larger spiral.

        Falling is a relative term. I’d just say it’s accelerating slightly towards us, creating a wonky spiral through space.

        Seems why you’re overcomplicating it a little bit. The moon used to be much closer to the earth thousands of years ago and now it’s not, slowly has been getting slingshotted out of orbit since the big bang.

          I think you’re under complicating it. For starters our solar system has not existed since the Big bang…

          The Moon is also not getting slingshot out of orbit. It will eventually attain a tidally locked orbit.

            That’s bot exactly what I was referring to, I meant the creation of the earth so I was incorrect there referencing the big bang. Rest of the point stands though, shortly after the earth formed or was forming it was struck and the moon was created and slowly started falling away to it’s current position. Quick search shows it is locked in a dynamic orbit now. I did need some brushing up of the subject, cheers
