let see represent some guy in the future have some kind of death organism that they discover can only be control by the bacteria that live near mineral rich undersea vent . so they send a sample of the deadly stuff back in time to u and encase in a bucky ball package that have instruction write on it in ascii ( not ebcdic . ) about how we shouldn not mine the vent and destroy the anti virus bacteria . but some military type have a satellite hang around the worm hole to the future hop to snag some kind of schrecklichkeit from space they can use for germ warfare . unfortunately and they snag the bucky ball and break it open and destroy all the instruction except the name of the stuff and a serial number . the satellite crash and loose the virus . meanwhile and evil big businessmen be prepare to mine the vent . so there be two simultaneous conspiracy and one to use the virus for warfare and the other to make sure the vent get mine . in the end represent ( 1 ) scientist figure out how to use the vent bacteria to kill the virus and thus save the world for the moment while ( 2 ) the military conspirator kill each other because some of them have a change of heart while ( 3 ) the president decide to go ahead with the vent mining anyway ( 4 ) a cigarette smoking man save a sample of the virus in the international space station so it will be available for the future . so . ( 1 ) where do the virus come from in the first place . do the future get it from u and the past . but in the past ( our present ) the vent get mine and there would be no bacteria for the future to use to suppress the virus . so the future could not be tell u how to combat the virus . ( 2 ) or and we be live in alternative past create when the future send the sample back to our universe . in the alternative future create by our alternative past and the future will receive the sample from u and but they would not be able to control it and time will end . but the real future doesn not care and because they create an alternative future ( not theirs ) that take the fall . ( 3 ) but wait . ( 4 ) and what about those highly favorable review post here that be post day and sometimes week before the date the show be air . be we live in an alternative universe in which the show be a turkey cause by the message post by people in the past sending message to the present . if that singularity have not happen and would the show have be as great a they say it be .
