Prevention:
- Have the tough conversations:
- Ask your parents, "Was I born in the normal way? Or was I created in a particle accelerator by firing charged particles at a wall of heavy nuclei?"
Common Questions:
- Will touching my doppelgänger kill me?
- To the outside observer, you and your doppelgänger will appear to mutually annihilate in a burst of ionizing radiation. However, it may be of some consolation that, under the Feynman–Stueckelberg interpretation, this is equivalent to your body reversing its temporal direction--that the doppelgänger you have been so scared of is simply you traveling backwards through time.
- Is seeing your doppelgänger a bad omen?
- Yes.
- Is seeing someone else's doppelgänger a bad omen?
- Do you want them to be annihilated in a burst of ionizing radiation?
