Gravity seems holographic. What does that mean for reality?

    > Holography implies that you can do that — reconstruct every fold, vessel, and neuron in three dimensions — without actually looking inside. Simply photographing the surface of the brain somehow suffices.

    Gah I am not a fan of pop-sci simplifications like this for the sake of a soundbite. The author goes onto explain how no, a picture is not enough, you need to actually measure the distortion of spacetime at the surface. Somebody is going to walk away thinking this stuff is possible, that maybe psychics really can detect something wrong with them.

      It is Quanta, the home of sensationalist oversimplifcations. What did you expect, solid science?

        Yes, the rest of the article is pretty good.
