Thought experiment.

Imagine if on Saturday 3rd January 2009 a paradox was created.

A paradox that meant, that even if time travel was invented, one could not return to change the events of January 3rd.

A successful change of that Saturday would remove the need to return to change the event.

That paradox would echo in time until it disappeared and time would move on seemingly unaffected by infinite efforts.

That makes all other efforts look so insignificant.

Immutable Truth Saturday 3/1/09 happened and it cannot be rewritten.

Immutable.

True.

Have fun being awake.
