    to be a little pedantic, if you take in account the rate of expansion of the universe, and take as a truth that the ghost stays stationary in spacetime, earth would disappear in an instant

        That’s a fair point. So then one might expect the ghost to continue their motion tangential to the orbit of the earth, and so they’ll float away.

        However, the theory of general relativity suggests that gravity isn’t really like other forces. It doesn’t push or pull anything at all; but rather its bends the fabric of time and space. Objects ‘falling’ due to gravity, or ‘in orbit’ around a planet are actually moving in a direct straight line in curved space-time. And this is why gravity still applies to massless objects such as light. So then, I’d say the ghost would still be affected by gravity - and that their main concern would be falling into the earth rather than drifting away.

    So there’s just a long ass trail of ghosts floating in space?

    At least some sections would be heavily populated…

    Nothing is as terrifying as SpaceEngine.

    Frankly. This… software rearranged my brain and changed me fundamentally.

    There are no words to describe being lost in the 10^27 of space. It’s just too much, you will go insane and if you survive you will lose the ability to talk with people, lose every single thing that you thought matters. You will be alone even in the busiest of places, some part of you forever stuck in the 10^27 of emptiness between Galaxy Groups.

    This isn’t a joke. Ignorance is bliss

      There is the Great Ghost Cluster in the distant void, passing messages up and down its endless stream of ghost bodies in order to log world events at the speed of voice.

        This is actually an awesome writing prompt: The older ghosts get updates from the younger ones, and send stories back from their own lives, like a long telephone wire…

          That story wouldn’t get to the beginning of the line without being completely changed to be unrecognisable

            That feels like practically a feature, when you have an eternity to fill and only a finite number of original stories with which to do so.
