I posit that time does not exist at all. People invented time to manage day to day life. But it’s an illusion. When I work time does not exist - I work as a shaman or healer.

My question is this: if a predestination paradox were to arise or a temporal causality loop wouldn't they exist for a seemingly brief time in an alternate reality of potential and then fade or pop out existence?

If a stable time loop were created it would need a tremendous amount of energy to remain stable, yes? no? maybe?

This scenario would need an explosion of a several megatons in a nuclear bomb to set an alternative reality in motion with a predestination paradox or temporal causality loop. Otherwise time would self-correct. Yes? No? Maybe? I'm not a scientist, nor a physicist, but...
