Suppose one fine day several gods and goddesses whom rules over light (apply to all electromagnetic spectrum) such as Hyperion and Apollo decided to ride Zhu Long, a chinese divine dragon whom also governs light all go on strike. My question is can we in the present day still be able to fly or ferry across seas and oceans? If so how can we proceed safely without begging for mercy? In this scenario assume the strike went on for about a week so that the air composition isn't lethal for us, assume all planes and ships either are about to leave ports or already on course when all photons ceased to exist. GPS satellites are still orbiting obediently around Earth but let's forget them they are just demoted to space junks and stars still going through nuclear fusion but don't produce photons any more.
