    • Consider the following gedanken experiment: Let us assume that we can localize the (sub-luminal) Planckian photon with almost zero velocity within 1 cm for a few seconds. Now we build a box made of ordinary (sub-Planckian) material around the Planckian photon, which is nearly at rest. Another (inertial) observer, however, who walks by at 1 m/s, also sees the Planckian photon standing still (remember: no preferred frame). So either this observer sees the Planckian photon (eventually) outside the box or, even more drastically, the (sub-Planckian) box following him/her. In both cases, locality is violated. Imagine, for example, that the Planckian photon interacts with some ordinary matter inside the box;

    • and, without non-locality, we know how ordinary matter and space-time behave on large scales.
