Ontological Paradox

An ontological paradox is a type of paradox and the opposite of the Grandfather Paradox. In an ontological paradox an item or information either becomes its past self or creates its past self. For example, an engineer is building a time machine and they find a notebook containing instructions on how to build one. They build the machine and then send a copy of the notebook back in time to where and when they first found it. An ontological paradox is currently impossible to make in Achron but the Predestination Paradox is possible.
