Honestly, the guy is talking shit its a shame there isn't a comment section so he can be told so, applying Earth based science to an alien organism that happens to bear a resemblance to an earth based one within a fictional show? I should think science doesn't make the blindest bit of difference to the survival of the show I think its more to do with viewers watching it.

Further, it doesn't matter if the "science" behind the spore drive is right or wrong. Science gets things wrong in our real world, all the time... and then has to be corrected. The trouble is, until that correction is made which may be years or decades later, everybody follows and listens to the first bit of information as that, rightly or wrongly is the "fact"...

But I digress, that is one for the community board... the show has bigger problems than a bit of inaccurate science... Science, is the least of its problems.
