    This is incorrect. Ghosts do have mass, they just don’t interact with the EM force and only through the gravity, the strong and the weak interaction (and a fifth interaction that we don’t know about). That’s right, all that dark matter and dark energy is actually ghosts.

      This is the best explanation I’ve heard for dark matter that doesn’t involve the assumption that our cosmological models are completely correct.

      Can we define ghosts simply as the extinguished consciences of sentient life? So, dark matter and dark energy are the thoughts and memories of our universe.

      With no mass they will continue in a straight line at the velocity they were at when they transcended.

      Ghosts everywhere!

    The only things that aren’t bound by gravity are massless. Massless things always have to be moving at the speed of light. So really the question is, what direction would the ghost shoot off to? Momentum would have to be preserved, so it’d be the opposite direction of where the corpse drops. Or maybe the corpse just move a teensy bit to the opposite direction of the ghost?

    Note: this assumes Newtonian or at least semi classical physics. In general relativity, there is no such thing as being unbound by gravity.

    I have a memory of seeing this exact idea in another comic on here but can’t find it! (Assuming it is a case of multiple discovery and not plagiarism)

    I always thought that this would be a similar issue with time machines. Go back even 1 second and you’re floating in the void.

      That’s actually kinda my head cannon as to why the doctor in doctor who is so hands on when piloting the TARDIS a time machine that only travels through time is useless because you can’t affect history while floating out in space and it’s also dangerous if you happen to pop into existence inside a block of dirt the more I think about it doctor who is a pretty realistic depiction of what time travel will be like even with the TARDIS moving air out the way before landing instead of creating a shockwave from TARDIS molecules materializeing inside of atmosphere molecules

    But in which frame of reference? Our solar system is also moving, so is our galaxy, our universe is “expanding”, and let’s not even talk about the multiverse, that’s overdone as it is.

    We move (with the Sun) around the Milky Way at about 792.000 km/h. At that speed, you wouldn’t even see the earth getting away from you.

    Maybe the gravity ghosts are subjected to is in relation to the location they died and not the mass of earth.
