time paradox n.
a paradox caused by an action of a time traveller which alters history so that the action is no longer logically possible, such as travelling into the past to murder a dictator which leads to a peaceful world from which the time traveller would have had no reason to depart; cf. grandfather paradox n., temporal paradox n.
Also time-travel paradox.
Someone, sometime later than 2806, copied Dwar Smit’s earleist calculations and directions, traveled back through time, and left them in your friend’s mail box. Dr. Hawkinson could therefore copy a machine that was not really made until centuries after his death! It sounds almost incredible at first. It’s what you might call a paradox.]

Once more I was confronted by one of the inexplicable paradoxes of time traveling. Here this man had learned my name before I told it to him; he had learned his own future before it transpired, through history books written half a million years before his birth.]

My dear Collingwood,…don’t drive yourself crazy trying to resolve the paradoxes of time-travel. ]

Cyril Kornbluth’s Dominoes and John Wyndham’s The Chronoclasm…are beautiful jobs of writing, but their time-paradox plots strike me as stale.

The exemplary form of time-paradox story is that which takes the closed loop and complicates it.
Time in P. Nicholls Encyclopedia of Science Fiction 605/1
‘A time-travel paradox,’ said the small man. ‘There wasn’t any failure with the equipment. It wasn’t the hardware. You just ran into one of the basic laws of the universe, something we don’t know much about yet. Fortunately it was just a little paradox.’

It creates a time paradox!… A person can’t be both alive and dead at the same time! It violates the laws of physics!

And this would not set up a time paradox.

We particularly enjoyed ‘From Here You Can See the Sunquists’ by Richard Wadholm, which, rather than sidestepping the old time-travel paradox of meeting yourself when you back into the past, confronts it head-on and builds the whole story around the premise.

If there’s an equivalent to the locked-room mystery within SF, it’s surely the time-paradox story…. Only a new and novel take on the subgenre is going to hold the attention, which is where the challenge lies. Enter Peter F Hamilton, whose time-paradox, crime-thriller novella [etc.].
