Metakosmia

The metakosmia (Greek: μετακόσμια; Latin: intermundia), according to Epicurean philosophy were the relatively empty spaces in the infinite void where worlds had not been formed by the joining together of the atoms through their endless motion. Epicurus held that the metakosmia were the abode of the gods, whom he considered to be immortal and blissful living beings made of atoms.
