Or we can use the Tapestry theory (as formulated by Doc Brown while teaching temporal mechanics at MIT.[I think it was the class of 2307.])
Time is a tapestry and we are the threads - pull on a thread and you may change the pattern. but Time is a living tapestry. It repairs itself and a thread that's been tugged on too hard may find itself attached to a different place/or time.
I recall hating temporal mechanics. It gives me a headache.
