World's First Time Machine.

This is the Daily Mail. This is not the Enquirer, nor is it the Onion.

Holy crap, y'all.

Causality doesn't forbid time travel. Only Strict Local Causality does.

If you have global causality, but not local causality, you get timre travel as a possibility. Including the "can't travel back before the first time machine goes online" kinit.
