The Swan site was situated over a pocket of exotic matter-energy, or EM. (Note: may need a better abbreviation; people are already starting to call it electromagnetic energy. --PC) The energy released by Juliet Burke's nuclear device was absorbed almost entirely by that EM, which spread over the island like fallout, weakly interacting with normal matter. This perfusion of EM exacerbated many of the already known properties of this island. EM has a different relationship with the arrow of time than does normal matter; the flow of entropy and heat can be halted or reversed, for instance, and biological processes can be sustained indefinitely. This presents in males as an increase in sperm count, and in females as an inappropriate, and fatal, immune reaction to pregnancy. There is still lively debate on the actual etiology of this reaction: is the supercharged immune system breaking through the placental barrier, or are the transplacental T-cells actually traveling through time from an earlier or later version of the woman? Further research may yield novel treatments for many diseases, particularly infertility and the recent outbreak of an unidentified immunosuppressant agent.
(Great, I think the Groots and AH will approve. Have you given any thought to Jerry's Quantum Consciousness station? He still insists he saw ghost of a Roman noblewoman when he visited the site last spring, and all this talk of the arrow of time and the suspension of natural laws will just spin him up. --HG)
