in which an event is among the causes of another event, which in turn is among the causes of the first-mentioned event.[3][4] Such causally-looped events then exist in spacetime, but their origin cannot be determined.

The notion of objects or information which are "self-existing" in this way is often viewed as paradoxical,[2] with several authors referring to a causal loop involving information or objects without origin as a bootstrap paradox,[6][7][8][9]:343 an information paradox,[6] or an ontological paradox.[10] The use of "bootstrap" in this context refers to the expression "pulling yourself up by your bootstraps" and to Robert A. Heinlein's time travel story "By His Bootstraps".

Funny. No definition includes things that "just are". Everything is not a paradox. Please understand the term you use (and even a brief glimpse at its history will show you're wrong) before you attack someone in your defense of it.


Additional: Chrono's salvation is not a time loop. There is no "loop" involved because his fate is open ended.
