Trope-a-Day: You Can't Fight Fate

You Can’t Fight Fate: According to everything known about temporal mechanics, the universe is a block universe – which is to say, while local causality violations are possible (effects can, sometimes, precede causes), global causality violations are not (effects, nonetheless, always have causes). Or to put it another way, while predestination paradoxes are permitted – and enforced – grandfather paradoxes are not. The probability of any event-chain that might lead to a global causality violation is always zero, and anything which happened in the past, even if it involves the future of your personal timeline, will necessarily happen.

You can sometimes fiddle fate, because what you think you know about the past is not always what actually happened in the past; but you can’t fight it head on. Free will may be stronger than destiny, but it’s not stronger than causality.
