Is the future trying to save us from ourselves? A series of scientific papers that have been kicking around for a couple of years suggest that if the Large Hadron Collider ever were to find something that shattered the cosmos, the future universe might protect itself by sending a backward-causality wave to break the LHC, or at least warn us.

Sure enough, the LHC is broken - leading The New York Times' Dennis Overbye to wonder half-jokingly whether there was something to the claim after all.

Does that sound spooky? What if I told you that the idea of going back in time to derail out a world-ending particle collider goes back even farther, to a novel written about the fate of the long-canceled Superconducting Super Collider? And that the author of that book is a physicist who has been conducting research into ... backward causality?

Interesting subject. Would not a backward causality (wave) create a paradox?

I need to go back two days to stop myself bashing my thumb with a hammer.
